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.

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

Digital Heater*

-32°F to + 175°F

*Requires 120 or 240VAC Power Supply

 

Atmospheric heaters:

Rated inputs are suitable for up to 2,000 feet elevation. For elevations above 2000 feet, reduce input 4% for each 1,000 feet above sea level, as high elevation reduces combustion performance.

Low NOx heaters:

Rated inputs are suitable for up to 5,000 feet elevation. For elevations above 5000 feet, consult the factory.

SECTION 3 - INSTALLATION INSTRUCTIONS

CALIFORNIA PROPOSITION 65 WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.

IMPORTANT NOTICE

These instructions are intended only for the use of qualified personnel, specifically trained and experienced in the installation of this type of heating equipment and related system components. Installation and service per- sonnel may be required by some states to be licensed. If your state is such, be sure your contractor bears the appropriate license. Persons not qualified shall not attempt to fix this equipment nor attempt repairs according to these instructions.

WARNING: Improper installation, adjustment, alteration, service or maintenance may damage the equipment, create a hazard resulting in asphyxiation, explosion or fire, and will void the warranty.

CODE REQUIREMENTS

NOTE: The heater should not be located in an area where possible water leakage will result in damage to the area adjacent to the heater or to 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 com- bustion air flow.

Installation must be in accordance with local codes, or, in the absence of local codes, with the latest edition of the the National Fuel Gas Code, ANSI Z223.1/NFPA54 and National Electrical Code, ANSI/NFPA 70, and for Canada, the latest edition of CAN/CGA-B149.1 and B149.2 Installation Codes, and Canadian Electrical Code, CSA C22.1 Part 1 and Part 2.
