AIR CIRCULATION OF THE HEATING SYSTEM
Always refer to the applicable building code before installing the hot air conduct.
It is recommended to install a floor screen in order to balance the air pressure between the
floor where the appliance is installed and the superior floor. It is also recommended to
install those floor screen to each home extremity.
An air supply must be installed if :
a) The appliance seems to have an irregular draft control, a smoke return, a bad
combustion and a counter-blow even though you have a combustion or not.
b) Your other appliances, such as hearths or other heating appliances, release odors,
heat badly, provoke smoke return or a counterblow, even though there is
combustion or not.
c) An opened window, even slightly, by a calm temperature (without wind) stops the
situation above.
d) Your home was built with isolated dandruffs and with well adjusted windows,
and/or was built with a mechanism to evacuate the interior air.
If, with these indications, there is not enough air infiltration, you must ensure an air
supply.
In doubt, it is recommended to ensure an air supply.
Hot air pipe : 8" diameter for 20 feet length.
6" diameter for 15 feet length.
