ONSIDERATIONS

Adhere to the following warnings and cautions when installing,
adjusting, altering, servicing, or operating the furnace.   To ensure
proper installation and operation, thoroughly read this manual
for specifics pertaining to the installation and application of this
product.

This furnace is manufactured for use with natural gas. It may be
field converted to operate on L.P. gas by using the appropriate L.P.
conversion kit listed in the

 PROPANE GAS/HIGH ALTITUDE INSTAL-

LATIONS section

 of this manual

Install this furnace only in a location and position as specified in

LOCATION REQUIREMENTS & CONSIDERATIONS section and INSTAL-
LATION POSITIONS section 

of this manual.

Provide adequate combustion and ventilation air to the furnace
as specified in 

COMBUSTION & VENTILATION AIR REQUIREMENTS

section of this manual.

Combustion products must be discharged to the outdoors. Con-
nect this furnace to an approved vent system only, as specified in

CATEGORY 1 VENTING

 section of this manual.

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 specified in 

GAS SUPPLY AND

PIPING

 section of this manual.

Always install a furnace to operate within the furnace’s intended
temperature-rise range with a duct system which has external
static pressure within the allowable range, as specified on the
furnace rating plate and 

OPERATIONAL CHECKS

 

section

 of these

instructions.

When a furnace is installed so that supply ducts carry air circu-
lated 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.

A gas-fired furnace for installation in a residential garage must
be installed as specified in the 

LOCATION REQUIREMENTS AND

CONSIDERATIONS

 

section

 of this manual.

This furnace may be used as a construction site heater only if
certain conditions are met. These conditions are listed in the 

PROD-

UCT APPLICATION

 

section

 of this manual.
