WINTER OPERATION
IF THE POOL IS NOT BEING USED FOR A MONTH OR
MORE:
Turn the heater off at the main gas isolation valve. For areas
where there is no danger of freezing, water should circulate
through your heater all year long even though you are not heating
your pool.
IF YOU LIVE IN AN AREA THAT HAS THE POTENTIAL
FOR YOUR POOL WATER TO FREEZE, IT IS VERY
IMPORTANT TO READ THE FOLLOWING:
When water freezes, it expands. Due to the high performance
of your Insnrg Gas Heater any expansion of water inside the
heater can cause significant and costly damage when it expands.
Therefore, it is vital to drain the water from the heater anywhere
where freezing is a possibility. The easiest way to drain the heater
is by loosening the inlet and/or outlet barrel union and allowing
the water to drain away. If the heater is below water level,
remember to close the valves before and after the heater first to
isolate the heater from the pool and eliminate the possibility of
draining the pool, then loosen the inlet/outlet unions and drain.
If the heater has been drained for freezing conditions,
remember to turn the pump on first to circulate the water
and fill the heater before turning the Gas Heater on.
