Heatmax Furnace Installation and Operation Manual

7.5.1 Authorized configurations in Canada and United States
7.5.2 Authorized configurations in United States only
The installation of this furnace in parallel with another furnace that uses the same system
of hot air ducts are not permitted in Canada. This type of installation is only allowed in
the United States only. Ideally, the maximum input of the existing gas, oil or electric
furnace should be equal to or higher than the wood furnace. It is mandatory to meet the
minimum clearances between the hot air ducts and combustible materials like the wood
furnace was installed alone. Necessary adjustments should be made to the furnace or hot
air ducts to maintain a static pressure of 0.20 PO.CE. To prevent a return air in either of
the two furnaces, a non-return ("back flow damper") damper must be installed. The non-
return damper is necessary to ensure that the hot air flow through the house and does not
return through the plenum of the other furnace. Depending on your installation (see
examples below), a damper may be installed in each plenum.
