Degree Bend Termination | United States Stove 6035 specs

DESIGN GUIDELINES FOR OUTSIDE COMBUSTION AIR CONNECTION

1)For installations with horizontal through-the-wall exhaust, it is strongly recommended that the stove combustion air be connected to the outside. If the home is newer or has been tightly insulated it is required to install outside combustion air. If you do not, then bring a 4-6 inch intake into the furnace room in the basement.

2)Connection to outside the house is REQUIRED for mobile home installations. We strongly urge use of the 60FAK Fresh Air Kit.

3)Only noncombustible pipe 2 inches in diameter is approved to use for outside air connections (straight or flexible). PVC pipe is NOT approved and should NEVER be used.

4)If the air inlet is connected to the outside, it MUST be terminated with a vertical 90-degree bend (down) or with a wind hood. Failure to do so could result in a burn back during high winds blowing directly up the air inlet during a simulta- neous power failure (see diagram above).

5)Blockage, excessive length, or bends in the air intake pipe will starve the stove of combustion air. A 90-degree bend is equivalent in restriction to approximately 30 inches of straight inlet pipe.

CAUTION: The operation of exhaust fans such as bath room fans, attic fans, etc. might starve the heater of combustible air creating a negative pressure in the room. Provide adequate ventilation in the room accompanying the heater. If not, the pressure switch may shut off operation of the heater. (Due to negative pressure)
