3. SAFE INSTALLATION REQUIREMENTS

Installation or repairs made by unqualified persons can result

in hazards to you and others. Installation MUST conform with

local building codes or, in the absence of local codes, with the

ANSI Z223.1 and the National Electrical Code NFPA70-f 990 or

in Canada the National Standard CANiCGA B149-1 and CSA

C.22.1 -Canadian Electrical Code Part 1.

The information contained in this manual is intended for use

by a qualified service technician familiar with safety proce-

dures and equipped with the proper tools and test instru-

ments.

Failure to carefully read and follow all instructions in this

manual can result in furnace malfunction, property damage,

personal injury and/or death.

• DoNOTusethisfurnaceas aconstructionheater.

• UseonlytheTypeofgas approvedfor thisfurnace(SeeRatingPlate).

• DoNOTuseopen flametotestfor gas leak.

• Sealsupplyand returnair ducts.

• Checktoseethatfiltersareinstalledcorrectlyandarethepropertypeand size.

NOTE:Itisthepersonalresponsibilityandobligationofthecustomertocontacta qualified

installerto ensurethat theinstallationisadequateandconformsto governingcodesand

ordinances.

CAUTION

It is recommended that aqualified service technician check the heat

exchanger integrity every two (2) years, after the first four (4) years of

operation.

4. LOCATING THE UNIT

ACCESS PANELS

See FIGURE1forageneralviewofunitandlocationofaccesspanels.

Carbon monoxide poisoning hazard.

Do NOTinstalltheunit in alocationthatwill permitdischargedairfromthecondenserto

recirculatetothe condenserinlet.

CAUTION

Do NOT operate unit in a corrosive atmosphere containing chlorine,

fluorine, or any other corrosive chemicals.

INSTALLATION

NOTICE

Unit will NOT operate properly unless it is installed level front to rear

and side to side.

The slope MUST NOT be greater than 1/8" per foot (10mm per meter).

For side to side leveling, the drain side MUST always be lower.

Ground Level Installation

Fire and/or explosion hazard.

Make certain the unit is equipped to operate onthe type of gas

available. Models designated as natural gas are to be used with

natural gas only. Models designated for use with liquefied pe-

troleum (LP) gas are shipped with orifices sized for commer-

cially pure propane gas. They MUST not be used with butane or

a mixture of butane and propane unless properly sized orifices

are installed by a licensed LP installer.

Failure to follow this warning can result in property damage,

personal injury, and/or death.
