WATER SUPPLY
CONNECTIONS
Plumbing should be carried out by
a qualified plumber. Use approved
plumbing materials only. The diameter
of the pipe lines should be a minimum of
1/2” copper or pex piping.
To conserve energy and to prevent
freezing, insulate both the cold and the
hot water supply lines. DO NOT cover the
drain valves.
WATER PRESSURE
GUIDELINES
Operation of the gas geyser requires a
minimum water pressure of 14 psi (0,5
Bar) and a minimum water flow rate of
2.5 Litres/min.
1. For long pipe runs water pressure can
drop and additional water pressure may
be required.
2. When the water is supplied from a
water tank, the height of the tank, the
diameter of the pipes and their relation
to water pressure, should be taken
into consideration.
3. For gravity fed water 5 meters head is a
minimum requirement.
GAS SUPPLY LEAK TESTING
1. The gas geyser and its gas connections
must be tested for leaks at the normal
operating pressures before using it.
2. Turn on the gas shut-off valve(s)
3. Use the soapy water solution to test
for leaks at all connections and fittings.
Bubbles indicate a gas leak that must
be fixed.
4. Once the appliance is operating, the
factory connections also need to be
tested for leaks.
