• DESCRIPTION AND OPERATION
These gas water heaters are equipped with:
• A stainless steel burner which can operate with Butane/Propane-Natural.
• A pilot which can be adapted to operate with Butane/Propane-Natural. It can be
taken apart easily for cleaning. Ignition is by piezoelectric spark ignition.
• A fully automatic progressive ignition system which needs no adjusting. This pre-
vents any black smoke being given off during the ignition process.
• A thermocouple safety valve which shuts off the gas supply to both pilot and main
burner in the event of accidental flame failure.
• An inter-ignition valve which cuts off the supply of gas to the burner during the
pilot ignition process, even if there is water circulating through the appliance.
• A total shut-off valve which shuts off the supply of gas to the burner and the pilot,
even during the response time before the safety valve closes.
• A water shortage safety valve which adapts the supply of gas to the burner to the
circulation of water through the appliance.
• A gas economy feature which enables the supply of gas to the burner to be
reduced by up to 60%, to adapt the operation of the appliance when the ambient
temperature of the water supply is high.
• An automatic water flow regulator.
• A temperature selector.
• A heat exchanger made from pure electrolytic copper.
• A draught diverter hood.
