3. APPLIANCE INSTALLATION

Before installation, please read the instructions carefully and make sure you
understand them:
The furnace must be installed in a state of the art manner. Installation must be made in
accordance with the CSA B.365(Canada) and NFPA 211(USA) standards concerning the
normalization of solid fuel units. For installation in United Sates, also refer to NFPA
90B(USA) « Warm Heating and Air Conditioning Systems ». If modifications have to be
made to the existing furnace, these have to be conform with the CSA B.139 (Canada) and
NFPA 31 (USA) regulation for oil furnaces.
Inspect the furnace to make sure that nothing has been damaged in the shipping. Pull
out the wiring kit and the instructions manual from the firebox of the furnace and the
cleaning tools from the heat exchangers.

UNIT LOCATION

The furnace must be installed where outside air supply will be sufficient for proper combustion.
In airtight houses, it might be necessary to install an outside air inlet (see details in: «3-
INSTALLATION» COMBUSTION AIR).
The furnace must be positioned so that the connector is as short as possible. Minimize the use
o
of 90 elbows.
The owner must ensure a proper installation to allow a safe operation of the
appliance.
MATCHING THE TRANSFER DUCT BETWEEN THE TWO HEAT
GENERATORS
Install the plenum and heating ducts in line as in option 1 of appendix 1. In series
connection should be considered only if in line connection is not feasible.
If the ducts are installed in series (appendix 1, option 2) and the oil furnace's fan limit
control is mounted on the plenum, the divider in the plenum must be installed at least 5"
(127 mm) above the fan limit control casing. This divider must be air tight.
Do not install connecting ducts in a way that would allow inversion of the air flow.
Do not use elbows with a radius less than 6 inches (153 mm).
The transfer duct between the existing furnace and the add-on must be at least 320
2
square inches(0.2m ) and deviations radius must be at least 6"(153mm). (see the drawing
on the following page)
Do not remove any safety device from the existing furnace.
