POSITIONING THE FURNACE

WARNING
Fire and explosion hazard.
The furnace must be installed in a level position, never
where it will slope toward the front.
Do not store or use gasoline or any other flammable
substances near the furnace.
Non-observance of these instructions will potentially
result in death, bodily injury and/or property damage.
CAUTION
This furnace is not watertight and is not designed for
outdoor installation. It must be installed in such a
manner as to protect its electrical components from
water. Outdoor installation will lead to a hazardous
electrical condition and to premature failure of the
equipment.
If the furnace is installed in a basement or on a dirt floor, in a
crawl space for example, it is recommended to install the
unit on a cement base 2.5 cm to 5.0 cm (1'' to 2'') thick.
The unit must be installed in an area where the ambient and
return air temperatures are above 15˚C (60˚F). In addition,
the heater should also be located close to the center of the
air distribution system.
2.2

CLEARANCES TO COMBUSTIBLE MATERIAL

2.2.1.

Heating unit

The furnace is approved for zero clearance to combustible
material regardless of the heating capacity.
2.2.2.

Supply air ducts

Ducts for furnaces with a heating capacity up to and
including 20 k W, can be installed with a zero clearance to
combustible material.
Ducts for furnaces of 23 kW or more must have a clearance
of 25 mm (1'') to combustible material for the first 0.9 m (36'')
of duct. Thereafter the clearance can be zero.
Units of 23 kW and up, installed in the downflow position
must use a DFB-FEM downflow base, which is especially
designed for this purpose.
clearances are being adhered to.

Upflow installation

The return air opening may be located on either side of the
furnace. Care should be taken not to damage the wires
inside, while cutting the opening.
supplied with the unit according to the instructions provided
with it. It is also recommended to install the blower door
before handling or moving the unit. Refer to Figure 1 for
additional details.

Downflow installation

When the furnace is installed in the downflow position on a
combustible floor,
materials must be adhered to. The downflow base DFB-
FEM can be used to ensure these clearances. Refer to
Figure 2 and the installation instructions provided with the
base.

Horizontal installation

2.3.3.
When the furnace is installed in the horizontal position, either
suspended or on a combustible floor with a choice of right or
left discharge, the clearances from combustible material
must be adhered to. Refer to Figure 3 for additional details.
