MAINTENANCE INSTRUCTIONS
It is recommended that you check the following items
at least every six months and at the beginning of every
swimming season.
1. Examine the flueing system. Make sure there are
no obstructions in the flow of combustion and
ventilation air.
2. Visually inspect the main burner and the pilot
burner flame (on millivolt models). The normal
color of the flame is blue, see Figure 3. When
flame appears yellow, burners should be inspected
and cleaned.
3. Keep the burner area clear and free from combus-
tibles and flammable liquids.
ENERGY SAVING TIPS
1. If possible, keep pool or spa covered when not in
use. This will not only cut heating costs, but also
keep dirt and debris from settling in the pool and
conserve chemicals.
2. Reduce the pool thermostat setting to 25
lower. This is accepted as being the most healthy
temperature for swimming by the American Red
Cross.
3. Use an accurate thermometer.
4. When the proper maximum thermostat settings
have been determined, tighten the thermostat knob
stopper.
5. Set time clock to start circulation system no earlier
than daybreak. The swimming pool loses less heat
at this time.
6. For pools that are only used on the weekends, it is
not necessary to leave the thermostat set at 25
Lower the temperature to a range that can be
achieved easily in one day. Generally, this would be
° C
° C
5.5
to 8.4
lower providing the pool heater is
sized properly.
7. During the winter or while on vacation, turn heater
off.
8. Set up a regular program of preventative
maintenance for the heater each new swimming
season. Check heat exchanger, controls, burners,
operation, etc.

SPRING AND AUTUMN OPERATION
If the pool is being used occasionally, do not turn the
heater completely off. Set the thermostat down to
°
18
C. This will keep the pool and the surrounding
ground warm enough to bring the pool up to a
comfortable swimming temperature in a shorter period
of time.
WINTER OPERATION
If the pool won't be used for a month or more, turn the
heater off at the main gas valve. For areas where there
is no danger of water freezing, water should circulate
through the heater all year long, even though you are
not heating your swimming pool. Where freezing is
possible, it is necessary to drain the water from the
heater. This may be done by opening the drain valve
located at the inlet/outlet header, allowing all water to
drain out of the heater. It would be a good practice to
use compressed air to blow the water out of the heat
exhanger.
