When using a Class A or double wall flue pipe connection, follow the manufacturer's instructions.
When constructing a single wall smoke pipe, the following guidelines must be observed.
1. The smoke pipe should be 24 gauge or heavier
stainless | steel or black pipe. |
2.Secure all joints with three #8 screws.
3.If the smoke pipe must pass through a wall, an ap-
proved | insulated or ventilated |
thimble, at least three times the | diameter |
of the smoke pipe must be used. (i.e. a 6" diameter smoke pipe needs an 18" thimble).
4. The smoke pipe should not be used as a chimney.
IMPORTANT INFORMATION FOR
ALL SMOKE PIPES
The smoke pipe must be constructed and installed so that it maintains clearances, keeps condensation and creosote within the pipe, and is capable of withstanding a two to three thousand degree chimney fire.
1.The smoke pipe should slant down toward the furnace a minimum of 1/4" to the foot. At no time should the pipe turn downward toward the chimney or run horizontal.
2.There should be no more than two 90 degree elbows.
3.The smoke pipe should never be longer than six feet. If it is absolutely necessary to make a run of more than six feet (not recommended) use extra support brackets every 3 feet.
4.The smoke pipe should never be reduced to a smaller size than flue opening on the furnace.
5.The smoke pipe should not block the flue of the
chimney | or extend into it in any |
way. |
|
6. A good airtight thimble should be used to hold the | |
smoke | pipe in the chimney. It |
should be constructed so the | smoke |
pipe can be removed for cleaning. |
|
7.The smoke pipe should not leave the heated portion of the building to reach the chimney.
8.The smoke pipe should not pass from one story to the next before entering the chimney, nor should it pass through any closed or enclosed space.
9.Heat reclaimers should not be installed or used in the smoke pipe.
10.The smoke pipe should not be located near or in a walk way or well traveled area.
11.All male ends of smoke pipe should run or point
towards | the furnace. |
DAMPERS ON STOVE PIPES
When burning coal, we recommend a Barometric Draft Damper be installed at a safe convenient place between chimney and your furnace.
When you have installed the smoke pipe connecting your furnace to the chimney, tap the pipe hard with your fingernail. Remember the sound it makes - it will be a "ting" echoing inside the stove pipe. If later you tap and hear a muffled thud, you are building up soot in the pipe and should clean it. This pipe should be cleaned at least once or twice during the
heating season.
DO NOT CONNECT TWO HEATERS TO THE SAME CHIM- NEY FLUE. The National Fire Prevention Association recom- mends that woodburning appliances vent into a separate chimney from gas or oil furnaces. If such an installation is contemplated, first check with a local building inspector to find out if a separate flue for a woodburner is required.
If codes allow, use extreme care in making such installations. Be sure that one pipe is higher than the other so that the two openings will not be opposite each other. Also, when connect- ing two heaters into the same chimney flue, the flue size should be large enough to handle both heaters. Very few codes and standards allow same flue connection. Such installations can cause severe problems. Gas hoods and barometric dampers allow excess air into the chimney causing cooling of the flue gases and a greater creosote
HEATED AIR DISCHARGE
The Hotblast furnace is designed for use as a supplemental heating source. When used as a supplementary furnace, the 1600/1800 is connected in conjunction with an oil, gas, or electric furnace to the existing duct work which distributes the heated air into several rooms and/or areas.
When used as a space heater, heated air from the 1600/1800 furnace is expelled directly into the room in which the furnace is located. In installations of this type, the flow of heated air from the furnace must not be blocked. It is recommended that an elbow be attached to the heated air discharge to divert the heated air away from combustibles. All other criteria for installation remains unchanged.
CONNECTING HOT AIR DUCT TO FURNACE
We strongly recommend that the hot air duct work be installed by a home heating specialist. If doing the installation yourself, before you decide which installation will best suit your needs, consult a qualified heating technician and follow his recom- mendations as to the safest and most efficient method of installation.
The following illustrations are the only acceptable configura- tions when installed with existing oil or gas furnaces.
