To determine the chimney height required for any installation see page 23.
A MAJOR CAUSE OF CHIMNEY RELATED FIRES IS FAILURE TO MAINTAIN REQUIRED CLEARANCES (AIR SPACE) TO COMBUSTIBLE MATERIALS. IT IS OF UTMOST IMPORTANCE THAT THIS CHIMNEY BE INSTALLED ONLY IN ACCORDANCE WITH THESE INSTRUCTIONS.
This chimney is intended for use with solid, liquid and gas fired appliances, including wood fired stoves, fireplaces and furnaces.
Maximum continuous flue gas temperature: 1000 F Brief forced firing 1400 F Tested to (10 minutes) 2100 F
The chimney should be the size recommended by the appliance manufacturer.
Use only ICC Model EXCEL 103HT components. Failure to do so will void the certification and warranty of the product.
Keep these installation and operating instructions in a safe location for future reference.
Contact local building or fire officials about restrictions and installation inspection in your area.
When wood is burned slowly, it produces tar and other organic vapours which combine with expelled moisture to form creosote. The creosote vapours condense in the relatively cool chimney flueof a slow-burnin fire. As a result, creosote residue accumulates on the flue lining. When ignited this creosote makes an extremely hot fire.
Some coals contain large quantities of Sulphur (up to 7%). When coal is burned, Sulphur and coal ash are deposited in the chimney flue. This deposit combines with moisture to form a highly corrosive acid (Sulphuric Acid). In order to protect your chimney, we recommend that you:
1. Burn only low Sulphur coals (less than 1% Sulphur).
2. Have your chimney cleaned within 48 hours of shutting down you stove at the end of the heating season. Be certain that all the soot is removed.
If you are planning to install a wood stove, we recommend that you:
1. Choose a stove that has a label of a recognized Testing Laboratoy (such as UL, CSA, VVH, ULC). The EPA approved, low emissions stoves are highly recommended.
2. Connect only one solid fuel burning appliance to a chimney. Do no connect an oil or gas burning appliance to a chimney venting a solid fue burning appliance.
3. Never over fire your stove. If any part of the stove or stove pipe is glowing red, then you are over firing. Immediately close the stove's damper until the system cools. The high temperatures caused by over firing can permanently damage the stove and stove pipe and may overheat nearby combustible walls and furniture.
4. Install the stove and stove pipe as described in the Installation Instructions accompanying the stove. BE CERTAIN TO MAINTAIN THE REQUIRED CLEARANCES TO COMBUSTIBLE CONSTRUCTION.
5. Keep your flue gases between 300 and 500 F. This will maximize efficiency while minimizing condensation and creosote formation.
6. Do not burn sea driftwood. Salt is highly corrosive to all types of stainless steel. Do not burn treated lumber.
KEEP YOUR CHIMNEY CLEAN Wood stoves can quickly create large deposits of creosote in the chimney. Some wood stoves can create enough creosote in two weeks to cause a chimney fire.
When using a wood stove, we recommend that you:
1. Initially inspect the chimney system weekly. From this you will learn how often it will be necessary to clean your chimney.
2. THE CHIMNEY SHOULD BE INSPECTED AT LEAST ONCE EVERY -TWO MONTHS DURING THE HEATING.SEASON to determine if creosote or soot has built up. When a maximum of ¼" of creosote or soot has accumulated, it should be removed to reduce the risk of a chimney fire.
3. Have your chimney cleaned by a qualified chimney sweep. If you want to clean your chimney yourself, then; clean your chimney using a properly fitting nylon or steel brush. Do not use a brush that will scratch the stainless steel interior of the chimney. Use of an oversize brush may damage the chimney.
4. Do not expect chemical chimney cleaners to keep your chimney clean. Their use does not negate the necessity of periodically inspecting and cleaning your chimney.
If you are having a chimney fire, follow these steps:
1. Close all heater doors and combustion air controls. For fireplaces, block the fireplace opening with a noncombustible material (such as a steel sheet).
2. Alert your family to the possible danger.
3. If you require assistance, alert your fire department.
4. If possible, use a dry chemical fire extinguisher, baking soda or sand to control the fire. Do not use water as it may cause a dangerous steam explosion.
5. Watch for smoldering or fire on combustibles next to the stove, stove pipe and chimney. Check outside to ensure that sparks and hot embers coming out of the chimney are not igniting the roof.
8. Do not use the stove again until yourchimney and stove pipe have been inspected by a qualified chimney sweep or Fire Department Inspector.
1. The chimney is intended for use with cooking, heating and other low-heat appliances.
2. A chimney venting a fireplace or an incinerator shall not vent any other appliance.
3. The clearance between single wall stove pipe and unprotected combustible material must not be less than 18" (reference the National Building Code and NFPA 211).
The distance between a vertical stove pipe and the ceiling may be less than 18" when it is installed with an Excel 103HT support. The reduced clearance in this area has been confirmed as part of the chimney safety testing.
The distance between the horizontal stove pipe and a vertical wall may be less then 18" where the insulated chimney passes horizontally through the wall using an Excel WRS. The distance will be determined by the WRS.
4. The maximum height of unguyed chimney above the roof is 5 feet.
5. Portions of the chimney which may extend through accessible spaces shall be enclosed in all cases to avoid personal contact with the chimney and damage to the chimney.
6. Do not fill the air space around the chimney with insulation or any other material. Do not fill the factory built supports or radiation shields with insulation. Insulation placed in this area could cause adjacent combustibles to overheat.
7. The chimney shall extend at least 3 ft. above its point of penetration with the roof and at least 2 ft. higher than any wall, roof or adjacent building within 10 ft. of it. For chase installations, the chimney must extend at least 8" above the top of the chase.
8. Excel must be assembled using the stainless steel screws supplied with the chimney.
9. The following does not apply to installation in single and two-family dwellings: Factory built chimneys which extend through any story above that on which the connected appliance is located are to be provided with enclosures having a fire resistance rating equal to or greater than that of the floor or roof assemblies throuah which they pass.
To determine the chimney height required for any installation see page 23.
Typical round and square support installations are shown in drawings 1 thru 4 on page 8.
The clearance between the chimney and combustible material must not be less than 2" except for areas protected by the support. Do not fill this area with insulation. If the support is installed in a cathedral ceiling, follow the instructions for Cathedral Ceilings.
If the support is installed in a ceiling with an attic directly above, the support also acts as the attic radiation shield when installed with a CARST attic radiation shield top.
I. Locate the chimney in a convenient place as near as possible to the appliance outlet. Cut and frame the holes in the floor ceiling and roof where the chimney will pass. Refer to the technical specifications on page 3 to determine the required rough opening for the support model and size you are installing.
NOTE - Look Up - The round and square supports are designed to protect the surrounding combustible materials and as a result they permit 1" clearance from the chimney to combustible framing - in the area that they protect. When these supports are installed in a roof truss insure that the chimney has 2" clearance at the top of the truss. This may require you to block out the support at the bottom. Another option is to install a support extension (see page 13). Trim the support extension flush with the roof, this will permit the chimney to pass within 1" of the truss.
2. From below, push the support into the framed hole. The support must protrude at least 4" below the finished ceiling. Nail the support to the framed joist using 8 - 3" spiral nails or # 8 X 1 l/2" wood screws. Place the Finish Collar around the support and fasten it to the ceiling using the two screws provided. Note: If you are using a 6" square support you may find it difficult to screw it in place because there is not much room inside it. We have provided angle brackets with this support which can be screwed to the outside of the support box and nailed to surrounding framing as required. Use a minimum of four # 8 X 1/2" screws per bracket. In some cases these brackets may need to be trimmed (e.g.: to fit under a flashing).
3. Attach the flue extension (found in the support box) to the bottom of the first chimney length using the 3 metal screws provided. Put this chimney length, with the flue extension down, in the support. Push it down firmly in place.
4. From below, install a firestop - radiation shield in each additional floor through which the chimney passes.
5. Stack the next chimney length on the first length. Line up the exterior vertical seams and this will ensure that the screw holes align. Fasten the three screws supplied through the holes to fasten the chimney together.
6. Continue until the required chimney height is reached.
At the attic level, install a radiation shield (RS) from below. This shield acts as the joist and the attic radiation shield.
IF YOUR CHIMNEY IS ENCLOSED IN THE ATTIC, PROCEED AS FOLLOWS :
7. Install the roof radiation shield in the roof joists.
8. Install a vented roof flashing on the roof.
IF YOUR CHIMNEY IS NOT ENCLOSED IN THE ATTIC, PROCEED AS FOLLOWS:
7. Install a Storm Collar (SC) over the attic radiation shield. This will prevent insulation or debris from falling into the area around the chimney.
8.Install a regular roof flashing.
CONTINUE
Put the roof flashing in place. Seal the joint between the roof and the flashing with roofing tar or silicone.
For sloping roofs, place the flash ing under the upper shingles for approximately half of the flashing length and the on top of the lower shingles.
Nail the flashing to the roof using roofing nails. Place the storm collar over the chimney and the flashing. Tighten it in place. Caulk the joint between the chimney and storm collar with silicone.
9. Fit the rain cap to the top of the chimney. Screw the three metal screws provided through the straps and into the top chimney length.
If your home has a cathedral ceilings (no attic space between the ceiling an the roof), install the chimney and support as follows.
1. Situate the chimney in a convenient location as near as possible to th appliance outlet. Cut and frame a hole in the roof for the support. The sides ( this hole must be vertical (see page 3 for hole size) 2. Place the support in the opening. Lower it to the correct height a determined by the table and diagram below.
Using a level, make sure the support is vertical. If the support extends abov the roof, cut it flush with the top of the roof. Nail the support to the fram opening using 8 - 3" spiral nails or # 8 X 1/2" screws. Note: If you are using 6" square support you may find it difficult to screw it in place because it is less tha 10" x 10" inside. We have provided angle brackets with this support which can be screwed to the outside of the support box and nailed to surrounding framing a required. Use a minimum of four # 8 X 1/2" screws per bracket. In some cases thes brackets may need to be trimmed leg: to fit under a flashing).
Place the Finish Collar around the support and fasten it to the ceiling using two screws provided.
3. Attach the flue extension (found in the support box) to the bottom of the fi chimney length using the 3 metal screws provided. Put this chimney length in t support. Push it down firmly in place.
4. Use a regular roof flashing. Put the roof flashing in place. Seal the joint between the roof and the flashing with roofing tar or silicone. Place the fiashing under the upper shingles and on top of the lower shingles. Nail the flashing to the roof using roofing nails. Place the storm collar over the chimney and flashing. Caulk the joint between the chimney and collar with silicone caulking.
5. Put the remaining required lengths of chimney in place. Fasten the lengths together using three metal screws at each joint (provided with the chimney). If the chimney extends more then 5 feet above the roof, install a roof brace.
6. Fit the rain cap to the top of the chimney. Screw the two metal screws provided through the straps and into the top chimney length.
Steep pitched cathedral ceilings may require the use of a support extension. This piece fits down inside the support and can be adjusted to increase the support's length by up to 16". The extension is attached to the support using the eight metal screws provided. Be sure there is at least a 2 inch overlap where the extension joins the support.
The universal band is a sub-component of the following parts:
WALL BAND (WB) WALL SUPPORT (WS) ROOF BRACE (RE) OFFSET SUPPORT(OS)
The universal band is shipped frorn the factory pre-assebled for 6" diameter chimney. To use the band on 7" or 8" chimney simply move the bolts from the holes marked 6" to the corresponding 7" or 8" holes. The following instruction are not necessary in most cases since the bands come pre-assembled.
1. Place the two stainless steel band halves on a flat surface with the 90" tabs facing upwards. Overlap the two halves until the square hole corresponding with the size of chimney you are installing lines up with the 8" hole on the other half. As you can see in the drawing the outside hole is for 8" chimney, the middle hole is for 7", and the inside hole is for 6".
2. Insert a 1/4 inch X 1" elevator bolt through the square holes so that threaded end points upwards, place two washers on the bolt, then tighten 1/4" nut.
3. Bolt on the additional components as required.
4. Bend the band around the chimney section and secure with the 1/4" X 2" bolt, lock washer and nut provided. The band will bend to conform with the diameter of the chimney. Always insure that once the support is installed you fasten the band to the chimney with the three metal screws providided.
The roof support is used to support the chimney on a flat or inclined roof.
When using a roof support the chimney must extend in to the room a minimum of 18 inches below the finished ceiling.
With the chimney extending through the hole in the roof proceed as follows
1. Assemble the support.
2. Slip the support down over the chimney until its brackets rest on the roof. Tighten the collar around the chimney, then secure it by screwing three metal screws through the holes in the collar and into the chimney. Tighten the four nuts which hold the brackets to the support band.
3. Center the chimney and nail or screw the support to the roof using 6 - 23 nails or # 8 X 1/2" wood screws.
ATTIC AREA - IF APPLICABLE
IF YOUR CHIMNEY IS ENCLOSED IN THE ATTIC;
IF YOUR CHIMNEY IS NOT ENCLOSED IN THE ATTIC;
1. Place a storm collar over top of the radiation shield. This will prevent insulation and debris from falli.ng into the radiation shield.
2. A nonvented roof flashing should be installed on the roof.
3. Put the roof flashing in place. Seal the joint between the roof and the flashing with roofing tar or silicone. For sloping roofs, place the flashing under the upper shingles and the on top of the lower shingles. Nail the flashing to the roof using roofing nails. Place the storm collar over the chimney and the flashing. Tighten it in place. Caulk the joint between the chimney and storm collar.
4. Fit the rain cap to the top of the chimney. Screw the two metal screws provided through the straps and into the top chimney length.
This support is used for resupporting a chimney above an offset. Install the chimney and elbows according to the installation instructions. Install the support as follows:
1. Assemble the support.
2. Slip the support down over the chimney to a convenient location. 3. Tighten the collar around the chimney, then secure it by screwing three metal screws through the holes in the collar and into the chimney. 4. Attach the support straps to the floor or roof structure using two 3" nails or #8 X 1 1/2" wood screws.
5. Continue installing the chimney.
If possible install an interior chimney as it will provide better performance tha an exterior chimney. In area with continuous temperatures below -18 C (O F) the use of an exterior chimney may result in operating problems such as poc draft, excessive condensation of combustion products and rapid accumulation of creosote when connected to a wood burning appliance. If you do install a exterior chimney, we recommend that you enclose it using an insulate enclosure.
NOTES:
1. The chimney may be enclosed or unenclosed. Maintain 2" clearance to combustible materials. Do not fill the space around the chimney with insulation or any other material.
2. A wall band must be used to secure the chimney to the wall. Maximum distance between wall bands is 8 feet.
3. The chimney must extend in to the room at least 4 inches.
4. The distance between a single wall stovepipe and a parallel combustible wall or ceiling must not be less then 18". The distance between the horizontal stove pipe and the unshielded vertical wall through which the insulated chimney passes is determined by the Wall Radiation Shield.
5. If an exterior installation is to be enclosed, allow for access to base of Tee to facilitate required cleaning.
6. The minimum distance between the bottom of the chimney and any horizontal combustible is 12".
1. Determine where the chimney will pass through the wall. - For concrete walls cut a hole slightly larger than the chimney. - For combustible walls cut and frame a hole 12 3/8" X 12 3/8" for 6 inch or 14 3/8 X 14 3/8 for 7 and 8 inch diameters
2. Woodwall:
From outside, put the exterior portion (the galvanized part with the square plate of the wall radiation shield in the hole. Nail the radiation shield in place usir 4 - 2" nails or# 8 X 1 1/2" wood screws. Seal the joint between the radiation shield and the wall with silicone caulking.
3. Assemble the Wall Support.
4. Fasten the Wall Support to the outside wall in a convenient location dire above the hole. Use 4 #10 X 3" or larger screws. Insure that the screws fastened into a structural member and not only to the wall sheeting. If the st locations do not line up properly you can use a wall channel available from y dealer. The Wall Support brackets are slotted to allow them to adjust in and out. Adjust the brackets so that the chimney is a minimum of 2" from the wall a parallel with it.
5. Fasten the Tee Cap to the bottom of the Tee.
6 .Fasten the required chimney length to the Tee side entrance. The horizont chimney section must extend through the finished interior wall by at least 4 inches.
7. Fasten a chimney length to the top of the Tee.
8. Install this assembly through the hole and through the Wall Support cell; Tighten the Wall Support collar around the chimney, then secure it using metal screws.
9. Stack the next chimney length in place. Align the vertical seams, this will also align the screw hales. Fasten the lengths together using 3 metal screv Continue until the required chimney height is installed. Some installers prefer to screw two or three vertical lengths together in advance, this is sometimes easier than installing the screws adjacent to the outside wall.
10. Install a Wall Band at 8' intervals. The Wall Band should be adjusted ensure the chimney is vertical and at 2" (or more) clearance to combustible
11. If the chimney extends more then 5' above the roof, it should be secured to the roof using a Roof Brace (RE)
12. Fit the rain cap to the top of the chimney. Screw the two metal screws provided through the straps and into the top chimney length.
13. Attach the flue extension (found in the WRS box) to the female end of the horizontal chimney length using the 3 metal screws provided.
14. Put the interior (black) portion of the Wall Radiation Shield (WRS) in to the hole in the wall and push it until it stops against the chimney length. Install the round Finish Trim. Adjust the wall radiation shield so that the chimney is horizontal and screw the Finish Trim to the wall.
NOTE
If the chimney passes through the roof, cut a hole large enough to provide 2" clearance between the chimney and the roof. See the Technical Specifications for the size.
Put the roof flashing in place. Seal the joint between the roof and the flashing with roofing pitch. For sloping roofs, place the flashing under the upper shingles and on top of the lower shingles. Nail the flashing to the roof using roofing nails. Place the storm collar over the chimney just above the flashing. Caulk the joint between the chimney and storm collar with silicone caulking.
If it is necessary to offset the chimney in order for it to pass through an upstairs cupboard or to clear a joist, do this by using 15" or 30" insulated elbows. A maximum of two offsets (4 elbows in all) is allowed in a chimney.
To determine the parts required for your installation refer to the drawing and the offset tables.
You may find it convenient to install an adjustable length between the elbows. This will allow you to offset the exact distance you require. The offset table ,n page 1 9 should be used when no adjustable length is required. Use the table ,n page 20 when an adjustable length is required
The maximum length of unsupported offset chimney is 8'. If the offset chimney is longer than 8', then it must be supported at 6' intervals using an offset support (OS) or wall band (WE).
Install the support and the chimney as described in the support's installation instructions. When you reach the height at which the elbow will be installed, proceed as follows:
1. Install the insulated elbow on the chimney length. Turn it in the required direction and fasten it to the chimney with the 3 metal screws provided. Since the offset direction varies from installation to installation the pre-punched holes will not line up.
2. Place the required length of chimney on the elbow. Fasten it to the elbow with the three metal screws provided.
3. Use another elbow to turn the chimney vertically. Again secure the elbow to the chimney length using three metal screws.
4. Install the remaining chimney as described in the support instructions.
5. An Offset or Roof Support must be installed above each offset (two elbows)to support the chimney above the offset.
This support is only used on a masonry fireplace to provide a positive connection to the chimney. it is not to be used in contact with any combustible material, such as a wood floor.
Once a fireplace is installed, bolt the Anchor plate to the fireplace. Install the chimney according to the Installation Instructions for the Ceiling Support. Omit step 2 since the Anchor plate acts as the chimney's support.
One wall band is required for every 8' of vertical chimney installed above a wall support.
1.Assemble the universal band.
2.The wall band bracket is slotted which allows it to adjust in and out. Adjust the bracket so that the chimney is a minimum of 2" from the wall and parallel with the wall.
3.Fasten the wall band bracket to the wall using #10 X 3" or larger screws. The wall band brackets may be turned away from or towards each other depending on the stud locations. Insure that the screws are fastened into a structural member and not only into the wall sheeting.
When Excel 103HT is approved with a factory-built fireplace, the chimney and fireplace are tested in combination, as a complete system. It is not possible to include specific installation instructions for each make and model of firepiace in these instructions, you must follow the instructions included with the fireplace you are installing.
The roof brace is required to provide extra stability for chimneys which extend more than 5 feet above a roof.
1. Assemble the universal support band. The bolt locations are the same as for a wall band.
2. Place the band at point at least two thirds of the way up the chimney. Adjust the length of the braces by telescoping one tube inside the other until the desired length is reached. The angle of the braces should not be more than 45 degrees from horizontal when fastened to the roof.
3. Tighten the locking bold very firmly. We recommend that you screw the inside and outside tubes together using # 8 X 1/2" screws to permanently lock them in place.
4. Secure the collar by screwing the metal screws provided through the holes in collar and into the chimney.
5. Fasten the braces to the collar using the nuts provided.
6. Fasten the other end of each brace to the roof using a #10 X 4" or larger screw and a washer. Insure that the screws are fastened into a structural member of t~ roof and not only into the roof sheeting. The two braces should be install aproximately 90 apart.
The use of a wall channel will simplify the installation of a wall band or wa support. The wall channel is 26 inches long to allow for 24 inch on centrl framing. Simply place the elevator bolts provided in a suitable location on th wall channel then screw it to a framing member. Use a minimum of four #1 X 3 inch screws.
