Commercial Pool Heaters
INSTALLATION
This pool heater meets the safe lighting performance criteria with
the gas manifold and control assembly provided, as specified in the
ANSI Z21.10.3/CSA 4.3 standard for gas-fired water heaters.
LOCATING POOL HEATER
1. Maintain all clearances from combustible construction when
locating pool heater. See Clearances from Combustible
Construction, this page.
2. Locate the pool heater so that if water connections should leak,
water damage will not occur. When such locations cannot be
avoided, install a suitable drain pan that is well-drained under
the pool heater. The pan must not restrict combustion air flow.
The pool heater manufacturer is not responsible for water
damage in connection with this pool heater, or any of its
components.
3. Install the indoor pool heaters so that the ignition system
components are protected from any water while operating or
during service.
4. You must install the pool heater on a level, non-combustible
floor.
5. Do not install pool heater directly on carpet or other
combustible material. A concrete-over-wood floor is not
considered non-combustible. Maintain required clearances
from combustible surfaces.
If installing the pool heater in an area with a combustible floor,
you must construct a special combustible floor base. See Base for
Combustible Floors, this page.
6. For outdoor models, you must install an optional vent cap.
Instructions for mounting the vent cap are included in the
venting section. Do not install outdoor models directly on the
ground. You must install the outdoor pool heater on a concrete,
brick, block, or other non-combustible pad. Outdoor models
have additional special location and clearance requirements.
See Outdoor Installation Venting, page 25. A wind proof cabinet
protects the pool heater from weather.
Clearances from Combustible Construction
Maintain minimum specified clearances for adequate operation.
Allow sufficient space for servicing pipe connections, pump and
other auxiliary equipment, as well as the pool heater. See rating
plate for specific service clearance requirements.
Right Side 3" (7.5 cm)
Rear 3" (7.5 cm) (3" min. from any surface)
Left Side 6" (15cm) (24" (0.61m) suggested for service)
Front Alcove* (30" (0.76m) suggested for service)
Top 3" (7.5cm)
Flue 1" (25.4mm)
Hot Water Pipes 1" (25.4mm)
*An Alcove is a closet without a door.
Note: No additional clearance is needed on the right side of the
pool heater for the observation port. An observation port is located
on both the right and left side of the pool heater.
Note: No additional clearances from combustibles are needed for
use of the Direct Vent (DV) air inlet assembly.

Base for Combustible Floors
There are no manufactured combustible floor base kits available for
990,000 - 2,070,000 Btu models. See Table-A for floor base kits that
are available.
If a manufactured combustible floor base kit is not used, you must
construct a base for combustible floor installation. Install the pool
heater over a base of hollow clay tiles or concrete blocks from 8" to
12" thick, extending at least 24" beyond the pool heater sides. Place
tiles or blocks so that the holes line up horizontally to provide a
clear passage through the tiles or blocks. Place a 1/2" fireproof
millboard over the top of the tile or block base. Place a 20-gauge
sheet metal cover over the fireproof millboard. Center the pool
heater on the base. Also follow this procedure if electrical conduit
runs through the floor beneath the pool heater. This base must
meet all local fire and safety codes.
