Heatmax Furnace Installation and Operation Manual

In such a case, when starting up the fire, do not operate appliances that evacuate air
outside the house, such as:
•
Range hood
•
Air exchanger
•
Clothes dryer
•
Bathroom blower
•
Ventilated central vacuum system
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.
Additional combustion air can be provided following the following methods, provided that
they satisfy chapter 4 of the CSA B365 standard for Canada:
-
Direct connection: solid fuel units can be connected directly to a source of new
combustion air only if they are certified for this kind of installation, which must respect
the manufacturer’s instructions.
- Indirect method: new combustion air can be brought into a pipe located within
approximately 300mm (12 inches) of the unit. If the pipe is too close to the furnace, it
may interfere with its operation.
- Mechanical ventilation system: if the house is equipped with a ventilation system (air
exchanger or heat recovery), the ventilation system may provide sufficient auxiliary air
to the solid fuel unit. Otherwise, the owner should be informed that the ventilation
system may have to be rebalanced by a ventilation technician after the installation of
the solid fuel unit.
