General Specifications
These heaters are design certified and tested under
the requirements of ANSI Z21.56/CSA 4.7 American
National Standard / CSA standards for gas-fired pool
heaters.
The heater is interchangeable and can be used either
indoors 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 heaters contain a self-
generating electrical system operating between .25
and .75 volts.
Ambient Temperature Rating of

Rated inputs are 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. For Canada,
reduce input 10% when installed at 2000-4500 feet
elevation.
INSTALLATION
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.
Code Requirements
Installation must be in accordance with local codes, or,
in the absence of local codes, with the latest editions
of the National Fuel Gas Code, ANSI Z223.1, and the
National Electrical Code, ANSI/NFPA 70; for Canada,
the latest edition of CAN/CGA B-149.
Base Installation
Heater must be mounted on a level surface. It can be
installed on combustible flooring. Heaters may not be
installed on carpeting.
Clearances
NOTE:
These instructions are intended for use by
qualified personnel only, specifically trained and
experienced in the installation of this type of heating
equipment and related system components.
Installation and service personnel may be required
by some states to be licensed.
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.
NOTE:
The heater should not be located in an area
where possible water leakage will result in damage
to the area adjacent to the appliance or to the
structure. When such locations cannot be avoided, it
is recommended that a suitable drain pan,
adequately drained, be installed under the
appliance. The pan must not restrict combustion air
flow.
WARNING:
The heater shall not be located in an
area where water sprinklers, or other devices, may
cause water to spray through the cabinet louvers
and into the heater. This could cause heavy internal
rusting or damage some electrical components, and
this would void the warranty.
