General Information

WARNING:

Installation methods other than those described

in the following sections must comply with the

National Fuel Gas Code and all applicable local

codes for providing sufficient combustion air to

the furnace.

Provisions must be made during the installation of this
unit that provide an adequate supply of air for combustion.

• Instructions for determining the adequacy of an

installation can be found in the current revision of the

NFGC (ANSI Z223.1 / NFPA54).

Consult local codes

for special requirements

. These requirements are for

US installations as found in the NFGC.

• The requirements in Canada (B149.1) are structured

differently. Consult with B149.1 and local code officials
for Canadian installations.

WARNING:

Combustion air must not be drawn from a

contaminated atmosphere. Excessive exposure

to contaminated combustion air will result in

safety and performance related problems.

To maximize heat exchanger life, the combustion air
must be free of chemicals that can form corrosive acidic
compounds in the combustion gases. The recommended
source of combustion air is to use clean air from outside.
DO NOT place any chemicals with flammable or caustic
vapors or these other corrosive chemicals near the
vent termination:

• Gasoline/Kerosene

• Permanent wave solutions

• Chlorinated waxes and cleaners

• Chlorine based swimming pool chemicals

• Water softening chemicals

• De-icing salts or chemicals

• Carbon tetrachloride

• Halogen type refrigerants

• Cleaning solvents

• Cements, glues, paint removers, varnishes, etc.

• Hydrochloric acid

• Masonry acid washing materials

• Plumbing Stack

Air openings in the door of the unit, warm air registers,
and return air grilles must never be restricted. If the unit
does not receive an adequate supply of air for combustion,
the flame roll-out control located above the burners will
open, turning off the gas supply to the burners. This safety
device is a manually reset switch.

IMPORTANT NOTE

DO NOT install jumper wires across this control to defeat

its function or reset the control without identifying and

correcting the fault condition.

If this control must be replaced, use only factory authorized
replacement parts. See the Replacement Parts List on

page 25

.

Vent Termination

This unit has been equipped with an integral venting
system and designed to operate only with this venting
system. No additional venting shall be used. This unit
must be vented to the outdoors.

WARNING:

This unit is intended for outdoor installation

only. Do not vent the unit through a conventional
venting system.

A vent cover assembly has been supplied with the unit
and can be found secured to the gas controls within
the control area of this unit.

Figure 2

shows the proper

installation of the vent cover assembly over the vent outlet
on the exterior of the corner panel. The fasteners used to
secure the vent cover assembly have been included in
the owner’s package. The vent cover assembly must

be installed to assure proper operation of the unit.

The following list summarizes the requirements for the

location of the vent system termination:

• The location of the vent termination must be consistent

with the National Fuel Gas Code (ANSI Z223.1) or CAN/

CGA-B149 Installation Codes.

• The vent termination must be located at least 4 feet

horizontally from any electric meters, gas meters,
regulators, and relief equipment.

• The vent termination must be located at least 3 feet

above any forced air inlet located within 10 feet.

• The vent termination must be located at least 4 feet

below, 4 feet horizontally from, or 1 foot above any
door, window, or gravity air inlet into any building.

• The vent termination must be located at least 1 foot

above grade.

• The unit should be installed in a way that prevents any

obstruction of the vent termination during accumulating
snow.
