PLANNING YOUR INSTALLATION

LOCAL AND NATIONAL CODE REQUIREMENTS

The installation of these appliances must conform with local codes or, in the absence of local codes, with the National Fuel Gas Code, (for USA) NFPA 54 / ANSI Z223.1-latest edition.

Air Circulation Blower: The blower electrical power cord must be electrically grounded per local codes or per electrical codes:

In USA, NEC, ANSI / NFPA 70-Latest Edition.

In Canada, CSA C22.1

WARNINGS

ELECTRICAL GROUNDING INSTRUCTIONS. THIS APPLIANCE IS EQUIPPED WITH A THREE-PRONG (GROUNDING) PLUG FOR YOUR PROTECTION AGAINST SHOCK HAZARD AND SHOULD BE PLUGGED DIRECTLY INTO A PROPERLY GROUNDED THREE-PRONG RECEPTACLE. DO NOT CUT OR RE- MOVE THE GROUNDING PRONG FROM THIS PLUG.

WARNING: TO AVOID ELECTRICAL SHOCK, ALWAYS ENSURE THAT THE POWER CORD IS UNPLUGGED (I.E., THERE IS NO ELECTRICAL POWER TO THE CIRCULATION BLOWER) BEFORE HANDLING THE CIRCULATION BLOWER OR PERFORMING ANY WORK ON THE APPLIANCE.

High Altitude: Gas inputs shown are for elevations up to 4500 feet. For elevations above 4500 feet, contact your gas supplier or qualified service technician regarding the necessary dera- tion of appliance (deration: replacing burner orifice with a smaller one to reduce input). Ratings must be reduced at the rate of 4 percent for each 1,000 feet above sea level. Refer to (for USA) NFPA 54 / ANSI Z223.1-latest edition for orifice re- sizing.

TOOL / EQUIPMENT LIST

The following tools and equipment are recommended for com- pleting the partial assembly required when the appliance is installed:

•1/4” wrench.

•1/4”, 5/16” nut drivers.

•Pipe wrench.

•Phillips head screw driver.

•Flat head screw driver.

•Pipe sealant compound.

•Leak test fluid.

•Leak test fluid “U” tube manometer or pressure gauge (0 - 16” (inches water column) H2O scale.

GAS PRESSURE (WC = Water Column)

Minimum inlet gas supply pressure for the purpose of input adjustment:

Natural Gas - 4.5” WC min. – 7.0” WC max.

Propane (LP) - 11” WC min - 13.0” WC max.

Manifold gas supply pressure:
	LOW		HIGH
Natural Gas -	1.8” +/-.3” WC	(to)	3.5” +/-.3” WC
	25,000 BTU / hr		37,000 BTU / hr
Propane (LP)	6.6” +/-.3” WC	(to)	10” +/-.3” WC
	28,000 BTU / hr		35,000 BTU / hr

Note: ” WC = Inches Water Column
