HeatMax II Furnace Installation and Operation Manual

Exhaust blowers that are in a fuel storage room should be installed so as not to create
negative pressure in the room where the solid fuel appliance is located.
A fresh air supply may be necessary to prevent solid fuel units from rejecting products of
combustion into the house. The indications used to determine if an additional fresh air
supply is necessary are not appropriate for all the situations. When in doubt, it is
recommended to install a fresh air supply.
A fresh air supply may be needed if:
- Solid fuel units present anomalies, such as irregular draft, smoke return, bad
combustion, and/or reversed draft (whether there is combustion or not);
- Existing solid fuel units such as a stove or fireplace release odours, heat badly, cause
smoke returns, or reversed draft (whether there is combustion or not );
-
The opening of a window, even slightly, in calm weather (windless), eliminates every
problem mentioned above ;
-
The house is equipped with a tight vapour barrier and adjusted windows, and/or is
equipped with an interior air mechanical evacuation device ;
-
There is excessive condensation on the windows in winter; and
-
The house is equipped with a ventilation system.
If, according to these symptoms or other similar ones, there is insufficient combustion air, it
is necessary to ensure an additional combustion air supply (see Section 6: Combustion
Air).
