CONDENSATE DRAIN
The Viron heater is a highly efficient gas appliance capable of generating 12 litres an hour of
condensation. Suitable drainage provision must be provided to ensure condensation does not build
up in the heater or flood damage surrounding areas. Do not raise the drain hose higher than the
exit point of the appliance.
Alternatively, the condensate can be used to replenish or “top up” your pool water. A Condensate
Drain Kit can be purchased separately and installed so that the condensate is returned into the pool
water.
When the heater commences operation, a solenoid valve will open the condensate line and allow
the vacuum created by the pump to draw the condensate into the pool water.
The condensate has a pH of approximately 6.8. Most chlorines and sanitisers used for pool water
disinfection will increase the pool water pH over a period of time, so an additional advantage of
the condensate produced by your Viron Heater is that the low pH will counter balance the high pH
of the disinfectant used in most pools.
IMPORTANT: Chlorines, disinfectants and sanitisers usually require a narrow bank of pH in
which to work effectively. Ensure you check the pH of your pool or spa weekly, and adjust as
necessary.
