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ammableorcaustic

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

correctingthefaultcondition.

If this control must be replaced, use only factory authorized

replacement parts speciﬁed in the Replacement Parts

List provided online.
