Viron Pool and Spa Heater

MAINTENANCE
It is recommended that you check the following at least every six months and at the beginning of
every swimming season.
1.
Examine the flue outlet and panel louvres for blockages. Make sure there are no obstructions
to the flow of air to or from the appliance.
2.
Keep the heater area clear and free of combustibles and flammable liquids. Chlorine should
not be stored in the vicinity of the heater. Chlorine and acid vapours, when drawn through a
heater, can rapidly cause corrosion of the heat exchanger.
3.
Keep the heater area free from garden refuse and debris. This will help prevent insects nesting
in the unit and ensure extended life and reliability of your heater.
4.
Have your heater professionally inspected at least every 2 years.
WINTER OPERATION
If the pool won’t be 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.
Where freezing is possible, it is necessary to drain the water from the heater. This may be done by
loosening the inlet or outlet barrel union. If the heater is below water level, isolate it from the pool
first by closing shut off valves before and after the heater.
CAUTION: If the heater has been drained for freezing conditions, do not turn on until the system
is circulating water.
