22). Do not use a restrictive gas cock.
The following gas pipe sizes are recommended for natural
gas supply piping. For low pressure LP gas, pipe size may
be reduced by 1/4", with a minimum pipe size of 3/4".
Check for compliance with local codes.

PRESSURE TESTING

Before operating the heater, the heater and its gas connec-
tions must be leak tested. Test all gas connections for leaks
with soapy water.
Risk of fire or explosion. Do not use an open
flame to test for leaks.
The heater and its individual shutoff valve must be discon-
nected from the gas supply piping system during any pres-
sure testing of that system at test pressures in excess of 1/2
psig (3.5 kPa).
The heater must be isolated from the gas supply system by
closing its individual manual shutoff valve during any pres-
sure testing of the gas supply at test pressures equal to or
less than 1/2 psig (3.5 kPa).
SUPPLYING POWER TO THE HEATER
The heater requires a 120V/60Hz/1Ph power supply.
Enclose the 120 Volt line to the heater in an approved flex-
ible conduit connected directly to the junction box on the
inside of the heater jacket.
Line voltage field wiring should be 14 gauge, with a circuit
capacity of 15 amps.

ELECTRICAL WIRING

1. All wiring must be in accordance with all applicable
codes.
2. The heater, when installed, must be electrically
grounded and bonded in accordance with local codes
or, in the absence of local codes, with the National
Electrical Code, ANSI/NFPA 70. A bonding lug is pro-
vided on the outside of the jacket under the vent for
this purpose.
3. Electrical power circuits to the pool heater must follow
local codes and National Electrical Code or Canadian
Electrical Code (as applicable).
4. All wiring between the heater and devices not attached
to it, or between separate devices which are field
installed and located, shall conform to the specifica-
tions of Type T wire (35°C rise).
5. All line voltage wiring shall be enclosed in approved
flexible conduit, and shall be securely attached to the
field wiring box located inside the jacket. The conduit
or cable connector at the field wiring box should con-
tain an insulating bushing or its equivalent to prevent
abrasion of the wires as they enter the box.
6. The filter pump should run continuously when the
heater is on, and for at least 15 minutes after the heater
is off. Any switches in the pump circuit that can dis-
connect the pump must also disconnect the heater.
7. Do not wire single pole switches, including protective
devices, into a grounded line. Observe hot/neutral
polarity when connecting power to the heater.
Connect the hot lead of the power supply to the black
wire, the neutral lead to the white wire, and the ground
wire to the green wire (See Figure 23).
A time clock controlling the filter pump should have a low-
voltage Fireman's Switch that switches off the heater at
least 15 minutes before shutting off the pump.
