Important notice:
The instructions herein are intended for the use of a
qualified technician, specifically trained and experienced in
the installation of this type of heating equipment. Some
states or provinces require that installation and service per-
sonnel performing the installation be licensed. If this is the
case in the state or province where heater is located, the
contractor must be properly licensed.
WARNING: Failure to comply with the appliance
installation instructions and service instructions in this
manual may result in equipment damage, fire, asphyxia-
tion, or carbon monoxide poisoning. Exposure to prod-
ucts of incomplete combustion (carbon monoxide) can
cause cancer and birth defects or other reproductive
harm.
Conformance with codes:
The heater shall be installed in accordance with all local
and state codes. The heater installation must conform to the
National Fuel Gas Code ANSI Z223.1 and with the require-
ments of the authority having jurisdiction. Design
Certification in the United States is in compliance with ANSI
Z21.56 (latest edition).
For Canadian installations, the heater is to be installed in
accordance with standards CAN/CGA B149.1 and B149.2 –
INSTALLATION CODES FOR GAS BURNING APPLI-
ANCES AND EQUIPMENT and/or local codes, and if appli-
cable, Standard CSA C22.1 – CANADIAN ELECTRICAL
CODE, Part 1.
Location of heater:
Locate the heater in an area where a leaking heat
exchanger or connection leak will not result in damage to
the area adjacent to the heater or to the structure.
This heater must be installed at least five feet from
the wall of an above-ground pool.
The heater shall not be installed with the top of the vent
assembly within 10 feet below or to either side of any open-
ing into the building.
Outdoor installation only:
The following installation and service clearances must be
maintained from surfaces to provide adequate air flow to the
heater.
Figure 1
An A.G.A. Certified main gas valve shutoff must be
installed outside of the cabinet and within 6 feet of the
heater
. Gas shutoff valve must have an inside diameter
large enough to supply the proper amount of gas volume to
the heater
.
NOTE: Do not use flexible appliance connectors on
any gas connections unless the connector is A.G.A.
approved for outdoor Installation, Is marked with the
BTUH capacity (which must be equal to or greater than
100,000 BTUH), and the type of gas (Natural or LP) to be
used.
Propane Gas:
All Propane gas tanks must be located outdoors away
from the pool and in accordance with the standard for stor
-
age and handling of propane gas,
ANSI/NFP
A
58 (latest edi
-
tion) and applicable local codes. If propane gas tank is
installed underground, the discharge of the regulator vent
must be above the highest probable water level.
Propane tanks must have sufficient capacity to provide
adequate vaporization for the full capacity of the equipment
at the lowest expected temperatures. Consult a propane
company expert for correct sizing.
Water piping:
This heater is designed for use with pool and spa/hot
tub water only, as furnished by municipal water distribution
systems. The warranty does not cover heater use with min-
eral water
, sea, salt, or other non-potable waters.
Do not install any restriction in the water pipe between a
heater outlet and the pool/spa with the exception of a three-
way switching valve and associated check valve. Blockage
of water flow from heater return to pool may result in fire or
explosion causing property damage, personal injury, or loss
of life.
Plumbing connections:
Water flow rate to the pool must be between 20 and 70
gpm. If flow rate exceeds 70 gpm an external by-pass valve
must be installed. Figure 2 shows a typical heater installa-
tion.
Electrical system:
This heater is equipped with a standard 3-prong 120 volt
cordset. The plug must be inserted into a GFI protected,
watertight, outdoor receptacle rated for at least 10 amps.
The heater must be electrically grounded and bonded in
accordance with local codes, or in the absence of local
codes, with the National Electrical Code ANSI/AFPA 70.
If the heater must be hard wired, open the junction box
and disconnect the cord. Remove the cord and strain relief
and wire the heater in accordance with local codes or the
National Electrical Code.
The ignition system used to light the burners is a direct
spark system which requires 120 volt AC current as does
the blower motor. The system amp draw is 2 amps.
It is strongly recommended that the heater be supplied
with a constant power source. If remote operation is
required, the heater should be controlled through the ther-
mostat only
.
Installation above or below water level:
This heater is supplied with a pressure switch factory set at
3.0 psi. If the heater does not operate and the pressure
switch is at fault, the following procedure is recommended to
adjust the switch:
