Check the rating plate and power supply to be sure that elec-
trical characteristics match. All models use nominal 115 vac,
1 phase, 60 Hz. power supply.
A furnace installed in a residential garage must be located so
that all burners and burner ignition devices are located no
less than 18" above the garage floor, and located or pro-
tected to prevent damage by vehicles.
The size of the unit should be based on an acceptable heat
loss calculation for the structure. ACCA, Manual J or other
approved methods may be used.
The furnace should be located using these guidelines:
1.
Where a minimum amount of vent piping and elbows will
be required.
2.
As centralized with the air distribution as possible.
3.
Where adequate combustion air will be available.
4.
In an area where ventilation facilities provide for safe lim-
its of ambient temperature under normal operating con-
ditions.
5.
Where it will not interfere with proper air circulation in the
confined space.
6.
Where the vent will not be blocked or restricted.
7.
Where sufficient space is provided to allow proper ser-
vice access. Minimum recommended service clearances
are as follows:
Twenty-four (24) inches between the front of the furnace
and an adjacent wall or another appliance, when access
is required for servicing and cleaning.
Eighteen (18) inches at the side where access is
required for passage to the front when servicing or for
inspection or replacement of flue/vent connections.
8.
Where it will not interfere with the cleaning, servicing or
removal of other appliances.
9.
Where the following minimum clearances (in inches) to
combustibles can be maintained. Please see Table 1
listed below.

An unconfined space is not less than 50 cubic feet per 1000

Rooms communicating directly with the space containing the
appliances are considered part of the unconfined space, if
openings are not furnished with doors.
A confined space is an area with less than 50 cubic feet per
1000 Btu/hr input rating for all appliances installed in that
