BASIC SYSTEM OPERATION
START-UP AND OPERATION
START-UP AND SHUTDOWN INSTRUCTIONS ARE ON THE LABEL ATTACHED TO THE INSIDE COVER OF THE APPLIANCE
WATER CONNECTION PANEL.
BEFORE START-UP
A. This appliance does not have a pilot. It is equipped
with an ignition device which automatically lights the
burners. DO NOT try to light the burners by hand.
B. BEFORE OPERATING, smell all around the appliance
area for gas. Be sure to smell next to the floor because
some gas is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
– Do not try to light any appliance.
– Do not touch any electrical switch; do not use any phone
in your building.
– Immediately call your gas supplier from a neighbor's
phone. Follow the gas supplier's instructions.
– If you cannot reach your gas supplier, call the Fire
Department.
C. Use only your hand to turn the gas control on or off.
Never use tools. If you cannot change the ON/OFF
setting by hand, don't try to repair it, call a qualified
service technician. Forced or attempted repair may result
in a fire or explosion.
D. Do not use this heater if any part has been under water.
Immediately call a qualified service technician to inspect
the heater and to replace any part of the control system
and any gas control which has been under water.
E. Do not operate the pool heater unless the pool or spa is
properly filled with water.

PUTTING THE HEATER INTO SERVICE

If the heater's Water Pressure Switches (PS) are below or above the water level by 1 ft (30 cm), after the heater
installation the Water Pressure Switch setting should be adjusted. See WATER PRESSURE SWITCH, in SAFETY
CONTROLS on page 14.
Note: Before putting the heater into service for the first time, follow the instructions under BEFORE START-UP
on page 12. Check for proper operation of the heater by following the steps under OPERATING INSTRUCTIONS

F. Before operating the appliance for the first time or
after it has been off for an extended time, perform the
following checklist:
1. Remove debris or other articles from inside the heater
and the area around the heater and its exhaust vent.
Make sure the ventilation openings are clear of debris
or obstruction. For installations in an enclosed space,
make sure openings for combustion and ventilation
air are unobstructed.
2. Keep heater area clear and free from combustibles,
flammable liquids and chemicals.
3. Check that all water connections are tight.
4. Water must be flowing through the heater during
operation. Make sure that pool/spa is filled with water
and have pump operating. Check that water flow is
unobstructed from the appliance. When operating
for the first time or after an extended shut-down, run
filter pump for several minutes to clear all air from
the system.
