Safety instructions
WATER SUPPLY
CONNECTIONS
Plumbing should be carried out by
a qualied plumber. Use approved
plumbing materials only. The diameter
of the pipe lines should be a minimum
of 1/2”.
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 ow rate of
2.5 Litres/min.
1. For long pipe runs water pressure can
drops 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. 5 meters above the shower head is
a minimum requirement if this is not
possible then gravity fed water is
not recommended
WATER SUPPLY
1. Sucient water pressure and ow rate
2. Make sure there are no water leaks
and that the water lter is clean.
3. Only compliant or specied materials
must be used
IMPORTANT
If the water ow is too slow, the gas
geyser will not ignite. Keep the shower
head clean from debris that reduces
ow rate.
To keep the water pressure balanced add
a 400-600kpa pressure regulating valve
on the cold water supply. Install a shuto
valve near the inlet of the gas geyser for
service and draining purposes.
Be sure to connect the water inlet and
the hot water outlet as shown on the
gas geyser. If reversed, the gas geyser
will not function.
Installation of unions or exible copper
connections are recommended on the
hot and cold water lines, so that the gas
geyser may easily be disconnected for
servicing.
Install a non-return between the gas
geyser and the water shuto valve.
