• PIPE WORK DIAMETERS AND CONNECTION SIZES
• 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.

• A set of water inlet and outlet and gas inlet accessories, which make it easier to
connect the heater to the main water and gas supplies.
OPERATION
Once the appliance has been turned on following the indications given in section
A.2.3. “Instructions for starting up the appliance” gas is supplied to the burner
whenever a hot water tap is turned on.
What actually happens is that when a hot water tap is turned on, water starts to cir-
culate through the appliance and a valve, controlled by a diaphragm device which
operates by differential pressure, opens supplying gas to the burner.
When the hot water tap is turned off, the water pressure in the appliance is interrup-
ted, as is the differential pressure in the control device, automatically shutting off the
gas supply to the burner.
Whilst the appliance is in operation, even if there are pressure fluctuations in the
mains supply, the temperature of the water is maintained at all times at the tempe-
rature preset with the “temperature selector” thanks to the action of the “automatic
water flow regulator”.
