COLD WEATHER OPERATION IMPORTANT FREEZE INFORMATION MODERATE CLIMATE: Heater operation can contin- ue during short-term cold spells. When temperatures are between 0° and 32°F, flow (continuous pump operation) must be maintained. CAUTION: Do not use the heater to maintain water temperatures just above freezing or for freeze protec- tion. When heater is used during freezing weather, care must be taken to avoid freeze-ups. Continuous pump operation is a must. Additional protection may be requir

SECTION 2 - GENERAL SPECIFICATIONS These heaters are design-certified and tested under the latest requirements of the ANSI Z21.56 / CSA 4.7 Standard for Gas-Fired Pool Heaters. All heaters can be used either indoor or outdoors. The appropriate top designated for each type of use is required. If necessary, the top can be changed at a later date to change from outdoor to indoor or vice versa. Millivolt heaters contain a self-generating electrical system operating between .25 and .75 VAC.

INDOOR HEATER INSTALLATION The heater is also design-certified for indoor installation when equipped with the approved drafthood. For Canada, indoor installation is restricted to an enclosure that is not occupied and does not directly commu- nicate with an occupied area. Refer to the latest edition of CAN/CGA-B149.1 and B149.2 for specific require- ments. Locate heater as close as is practical to a chimney or gas vent. Heater must always be vented to the out- side.
