SECTION 2 / GENERAL SPECIFICATIONS
These heaters are design certified and tested under the requirements of ANSI Z21.56 / CSA 4.7 American
National Standard / CSA Standard for Gas-Fired Pool Heaters. All heaters are inter-changeable and can be used
either indoor or outdoors. The appropriate top designated for that type of use is required. If desired, the top can
be changed at a later date to change from outdoor to indoor or vice versa. Millivolt heater contains a self-generating
electrical system operating between .25 and .75 volts.
Ambient Temperature Rating of Heater Components
Millivolt Heater with Honeywell Gas Valve +32°F to +175°F
Millivolt Heater with Robertshaw Gas Valve 0°F to +175°F
Electronic Ignition Heaters* -32°F to + 175°F
*Requires 120V or 240V Power Supply
Rated inputs suitable for up to 2000 feet elevation. For elevations above 2000 feet, reduce input 4% for each
1000 feet above sea level, as high elevation reduces combustion performance.
