(a) Seal any unused openings in the common

venting system.

(b) Visually inspect the venting system for proper

size and horizontal pitch and determine there is

no blockage or restriction, leakage, corrosion

and other deficiencies which could cause an

	Close fireplace dampers.
(d)	Place in operation the appliance being inspected.
	Follow the lighting instructions.
	Adjust thermostat so appliance will operate
	continuously.
(e)	Test for spillage at the drafthood relief opening
	after 5 minutes of main burner operation. Use
	the flame of a match or candle, or smoke from
	a cigarette, cigar or pipe.
(f)	After it has been determined that each
	appliance remaining connected to the common
	venting system properly vents when tested as
	outlined above, return doors, windows, exhaust
	fans, fireplace dampers and any other gas
	burning appliance to their previous conditions
	of use.
(g)	Any improper operation of the common venting
	system should be corrected so the installation
	conforms with the latest edition of the National
	Fuel Gas Code, ANSI Z223.1/NFPA 54. When
	re-sizing any portion of the common venting
	system, the common venting system should be
	re-sized to approach the minimum size as
	determined using the appropriate tables in Part
	11 of the National Fuel Gas Code, ANSI Z223.1/
	NFPA 54.

For special venting applications that require reduced vent sizes and through the wall venting, the optional D Series Power Vent can be used. Consult the factory or your local Raypak representative.

CAUTION: The heater and its manual shut-off valve must be disconnected from the gas supply during any pressure testing of that system at test pressures in excess of 1/ 2 psig (3.45 KPA). Dissipate test pressure in the gas supply line before reconnecting the heater and its manual shut-off valve to gas supply line. FAILURE TO FOLLOW THIS PROCEDURE MAY DAMAGE THE GAS VALVE. OVER PRESSURIZED GAS VALVES ARE NOT COV- ERED BY WARRANTY. The heater and its gas connec- tions shall be leak tested before placing the appliance in operation. Use soapy water for leak test. DO NOT use open flame.

NOTE: Do not use teflon tape on gas line pipe thread. A flexible sealant is recommended.

A minimum of 7 in. WC and a maximum of 10.5 in. WC upstream pressure under load, and no load conditions must be provided for natural gas or a minimum of 11 in. WC and a maximum of 13 in. WC for propane gas.
