General Information

This series is design certiﬁed in accordance with American National

Standard/CSA Standard Z21.86 and CSA 2.32 by the Canadian

Standards Association as a Fan Type Direct Vent Wall Furnace to

Any alteration of the original design, installed other than as

shown in these instructions or use with a type of gas not shown on

the rating plate is the responsibility of the person and company

making the change.
Important

All correspondence should refer to complete Model Number, Serial

Number and type of gas.
Notice: During initial ﬁring of this unit, oil from the heat exchanger

may bake out and smoke may occur. To prevent triggering of smoke

alarms, ventilate the room in which the unit is installed.
Installation in Residential Garages

Gas utilization equipment in residential garages shall be installed

so that all burners and burner ignition devices are located not less

than 18" (457mm) above the ﬂoor.
Such equipment shall be located, or protected, so it is not subject

to physical damage by a moving vehicle.
Qualiﬁed Installing Agency

Installation and replacement of gas piping, gas utilization equipment

or accessories and repair and servicing of equipment shall be

performed only by a qualiﬁed agency. The term "qualiﬁed agency"

means any individual, ﬁrm, corporation or company which either in

person or through a representative is engaged in and is responsible

for (a) the installation or replacement of gas piping or (b) the

High Altitudes

For altitudes/elevations above 2,000 feet (610m), input ratings should

be reduced at the rate of 4 percent for each 1,000 feet (305m) above

sea level, this may be accomplished by reducing manifold pressure.

The maximum allowable reduction in manifold pressure for Natural

gas shall be from 3.5" w.c. (.872kPa) to 2.8" w.c. (.697kPa). The

maximum allowable reduction in manifold pressure for Propane

(LP) gas shall be from 10.0" w.c. (2.49kPa) to 8.0" w.c. (1.99kPa).

For Canadian high altitude applications, this appliance is suitable

for installation at elevations between 0 feet (0m) and 4,500 feet

(1,372m) without change.
