INDOOR INSTALLATION (USA ONLY) OUTDOOR SHELTER INSTALLATION (CANADA)

(See additional instructions for outdoor PowerMax units in PowerMax Appendix)

All products of combustion and vent gases must be completely removed to the outside atmosphere through a vent pipe which is connected to the draft hood. A vent pipe extension of the same size must be connected to the draft hood and extended at least 2 feet higher than highest point of the roof within a 10 foot horizontal radius, and at least 3 ft. higher than the point at which it passes through the roof, or as permitted by local code; see Figures 21 and 22. The vent should terminate with an approved vent cap (weather cap) for protection against rain or blockage by snow. Double-wall vent pipe and an approved roof jack shall be employed through the roof penetration. The use of double-walled type B vent pipe is recommended.

The draft hood must be installed so as to be in the same atmospheric pressure zone as the combustion air inlet to the pool heater. The certified (factory) draft hood must not be modified in any way and must be employed in every indoor installation (with the exception of the PowerMax units).

The heater must be located as close as practical to a chimney or gas vent. The heater should be installed at least 5 feet away from the pool or spa.

The heater must be placed in a suitable room on a non-combustible floor or on a non-combustible base and in an area where leakage from heat exchanger or water connections will not result in damage to the area adjacent to the heater or the structure. When such locations cannot be avoided, it is recommended that a suitable drain pan with adequate drainage, be installed under the heater. The pan must not restrict air flow.

P/N 471048

Installations in basements, garages, or underground structures where flammable liquids may be stored must have the heater elevated 18 inches from the floor using a non-combustible base. The following minimum clearances from combustible materials must be provided.
