SECTION 2.
Installation
2.1 Pool Heater Placement
The pool heater must be placed to provide
specific clearances on all sides for maintenance and
inspections. There must also be minimum distances
maintained from combustible surfaces. These
clearances also apply to noncombustible materials
because the pool heater requires air circulation for
proper operation.
The pool heater should be mounted on a
level surface. An integral base for an installation
on combustible flooring is provided as standard
equipment on outdoor models. For indoor models,
special base rails part number 10539000 must be used
for combustible flooring.
Do not install a pool heater on carpeting.
Under the national Fuel Gas Code, ANSI Z223.1,
it is permissible to place the pool heater on floors other
than noncombustible when the installation complies
with the American Insurance Code. Figures 2, 3, 4 and
5 show common installation on combustible flooring.
2.2 Installation of Indoor Pool Heaters
Locate the pool heater to provide adequate
clearance for inspection and service on all sides. See
Table 1. For alcove installation, see Figure 6.
Install indoor heaters on a waterproof floor with
an adequate floor drain and a 6" (152mm) minimum
curb on all four sides to protect the building if heater
repairs are required.
The manufacturer will not be
held liable for any water damage in connection with
this pool heater.
2.2.1 Combustion Air Supply
The heater location must provide sufficient air
supply for proper combustion and ventilation of the
surrounding area as outlined in the latest edition of
ANSI standard Z223.1, and any local codes that may
be applicable. Inadequate combustion air supply may
result in incomplete combustion, sooting of the heat
exchanger, and unsafe operation of the heater.
a. Conventional Ventilation
In the United States, the most common of these
requirements specify that pool heater rooms should
be provided with two permanent air supply openings
communicating directly through the wall to outside
air one within 12 inches (305mm) of the ceiling, and
the other within 12 inches (305mm) of the floor. Each
opening should have a minimum free area of one
square inch (6.5 sq. cm) per 4,000 BTU/hr input of
the total input rating of all appliances in the enclosed
area. See Table 2 for recommended air supply for each
