INTRODUCTION

This 95% efficient gas fired furnace series is CGA / AGA
d
vent pressure) non-direct or direct vent central forced air fur-
nace. It is an upflow, downflow, horizontal left and right fur-
nace suitable for residential and light commercial heating
applications from 54,000 to 108,000 BTU/Hr. When installed
as a direct vent furnace, all combustion air is supplied direct-
ly to the furnace burners through a special air intake system.
(See Section “Ventilation and Combustion Air.”) 

All models may be fired by natural gas or field convertible to
LP gas (propane). The furnace is shipped completely assem-
bled except for the drain trap assembly and the venting.
Please inspect for damage when the furnace is unpacked. 

SAFETY

Throughout the manual, symbols and words are used to draw
attention to potentially hazardous conditions.

Safety Rules:

1. Use this furnace only with type of gas approved for this

furnace. Refer to the furnace rating plate.

2. Install this furnace only in dry indoor locations

(protected from weather).

3. Provide adequate combustion and ventilation air to the

furnace space as specified in the Determining

4. Combustion products must be discharged outdoors.

Connect this furnace to an approved vent system only, as

these instructions.

5. Never test for gas leaks with an open flame. Use a

commercially available soap solution made specifically
for the detection of leaks to check all connections as

instructions.

6. Always install furnace to operate within the furnace’s

intended temperature rise range with a duct system
which has an external static pressure within the
allowable range, as specified in the Furnace Sizing

t

7. When a furnace is installed so that the supply ducts carry

air circulated by the furnace to areas outside the space
containing the furnace, the return air shall also be
handled by duct(s) sealed to the furnace casing and
terminating outside the space containing the furnace.
(Furnace for heating the home located in the attached
garage, for example).

8. A gas fired furnace for installation in a residential

garage must be installed so that the burners and ignitor
are no less than 18 inches above the floor. The furnace
must be located, or protected to avoid physical damage
by vehicles.

9.
