VENT PIPING

WARNING: Indoor boilers require a drafthood that must be connected to a vent pipe and properly vented to the outside. Failure to follow this procedure can cause fire or fatal carbon monoxide poisoning.

Vent piping the same size as the draft hood outlet is recommended, however, when the total vent height is at least ten (10) feet (draft hood relief opening to vent terminal), the vent pipe size may be reduced as speci- fied in Chapter 10 of the National Fuel Gas Code, ANSI Z 223.1 (Canada-CAN/CGA-B149.1 and B149.2). As much as possible avoid long horizontal runs of vent pipe and too many elbows. If installation requires horizontal non-vertical runs, the vent pipe must have a minimum of 1/4 inch per foot rise and should be supported at not more than five foot intervals. Plumbers tape, criss-crossed, will serve to space both horizontal and vertical piping. Gas vents supported only by the flashing and extending above the roof more than five feet should be securely guyed or braced to withstand snow and wind loads. We recom- mend use of insulated vent pipe spacer through the roofs and walls. Another option for installation that requires horizontal runs is using the D-2 power vent kit option.

Power Vent

For more detailed D-2 installation information consult the D-2 Power Vent manual 6000.57.

The power vent assembly is a fan-assisted combustion system designed for application to Raypak Pool Heater Models 185-405. The unit, when installed as directed, is capable of operating in applications such as through-the- wall venting and reduced horizontal and vertical vent pipe sizes in new and current installations. It is certified for Category III venting up to 40 feet equivalent 4" diameter venting. The unit is factory wired for 240V, with capability of rewiring for 120V.

For protection against rain or blockage by snow, the vent pipe must terminate with a vent cap which complies with the local codes or, in the absence of such codes, to the latest edition of the National Fuel Gas Code, ANSI

Z223.1 (Canada-CAN/CGA-B149.1 and B149.2).

The discharge opening must be a minimum of two feet vertically from the roof surface and at least 2 feet higher than any part of the building within 10 feet. Vent stack shall be at least five feet in vertical height above the drafthood outlet. The vent cap location shall have a minimum clearance of 4 feet horizontally from, and in no case below, unless a 4-foot horizontal distance is main- tained, from electric meters, gas meters regulators and relief equipment.

The weight of the vent stack or chimney must not rest on heater draft hood. Support must be provided in compli- ance with applicable codes. The heater top and draft hood must be readily removable for maintenance and inspection. Vent pipe should be adequately supported to maintain proper clearances from combustible construc- tion.

Type "B" double wall orequivalentventpipe is recommended. However single wall metal vent pipe may be used as specified in the latest edition of the National Flue Gas Code ANSI Z 223.1 (Canada-CAN/CGA- B149.1 and B149.2).

GAS SUPPLY CONNECTIONS

Gas piping must have a sediment trap ahead of the heater gas controls, and a manual shut-off valve located outside the heater jacket. All gas piping should be tested after installation in ac- cordance with local codes.

Fig. #RP 8090.0

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 PRESSURED GAS VALVES ARE NOT COVERED BY WARRANTY. The heater and its gas connections shall be leak tested before placing the appliance in operation. Use soapy water for leak test. DO NOT use open flame.
