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sufcient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.
