Maintenance
Materials in the device which come into contact with
water are suitable for use with drinking water.
Use wine vinegar into the appliance via the water supply.
Allowing the product to react and then thoroughly flush out
the appliance with plenty of fresh water. To sterilise the
water we recommend "Certisil-Argento". Other products,
particularly those containing chlorine are unsuitable.
In order to avoid the colonization of micro-organisms, heat
up the water heater to 70°c at regular intervals.
Fuses
The control board has a 2 amp mini type blade fuse. This
should only be replaced with a fuse of the same rating.
Fault Finding
Gas operation
When switching on , the
heater does not operate
- No 12 v supply
Check the power supply (operation voltage min 10.5 V)
Check the control board fuse
When switching on the
heater does not operate and
the red lamp lights up after
approximately 30 seconds.
- Cowl cover fitted
- Air in the gas supply
- No gas supply
- Incorrect gas pressure
Remove flue cover and or clear any obstruction.
Check gas valves and gas bottle

The electrical heating element is fitted with an excess
temperature cut out. In the event of a fault, switch off at the
control panel wait 10 minutes then switch on again.
Water supply
Water drips from the safety
valve
- Water pressure from supply
pump to high
Check pump pressure (max. 200 kPa), use a pressure
reducing valve connected to the central supply.
When opening the cold
water tap, hot water comes
out
- Hot water flows back
through the cold supply
Fit a non-return valve in the cold water supply (refer to
installation instruction).
