6. Connecting the Gas Supply
Follow the instructions from the gas supplier.
Gas Type
The gas type indicated on the Water Heater’s rating
plate (NG or ULPG) must match the type of gas
being supplied to the Water Heater.
Pressure Test
The appliance and its gas connections must be leak
tested before placing the appliance in operation.
If test pressures are in excess of 1/2 psi (3.5 kPa),
the appliance must be completely disconnected
from the gas supply piping system during the test
process.
Measuring Gas Pressure
• In order to check the gas supply pressure to the
Water Heater, a tap is provided on the gas inlet.
1. Remove the hex head phillips
screw from the tap.
2. Connect a manometer using a
silicon tube.
• In order to check the gas manifold pressure
on the gas valve inside the Water Heater. The
pressure can be checked by removing the hex
head phillips screw and connecting a manometer
with a silicon tube.
Gas Meter
Select a gas meter capable of supplying the entire
MJ/h demand of all gas appliances in the building.
Gas Connection
1. Fit a union to the Water Heater gas inlet for easy
connection and removal. The thread diameter is
20 mm.
2. Fit an suitably approved isolating gas cock in the
supply pipe adjacent to the Water Heater gas
connection.
3. Ensure that the supply pipe and the gas pressure
regulator (ULPG or Natural Gas) has sufficient
flow capacity for this and other appliances
connected to the fitting pipe.
4. For ULPG appliances ensure that gas cylinders
are of sufficient size. The Water Heater alone
will require 2 × 45 Kg capacity cylinders.
5. Before connecting the appliance to the gas
service, purge any debris or air from the gas
service.
6. Check all joints for leaks with an approved leak
tester after connection.
Pressure
Ensure measurement is taken when the appliance is
operating at maximum load.
NOTE THIS DOES NOT INDICATE THE SIZE
OF THE GAS SUPPLY.
The inlet gas pressure must be within the range
specified.
This is for the purposes of input adjustment.
WARNING
Gas pressures below the required minimum
pressure may result in ignition failure, personal
injury or death.
WARNING
Pipe Sizing
• In order to choose the proper size for the gas
pipe, consult local codes and/or the AS/NZS 5601.
• Size the gas pipe according to total MJ/h demand
of the building and length from the meter or
regulator so that the following supply pressures
are available even at maximum demand refer AS/
NZS 5601:
Supply Pressure
Natural Gas ULPG Gas
Min 1.13 kPa 2.75 kPa
Max 3.00 kPa 3.50 kPa
Installation Manual
24
7. Connecting the Water Supply
• Installation and service must be performed by a
qualified plumber.
• Observe all applicable codes.
Installation location
• If installing the Water Heater on a roof (Above
lower-level hot water supply):
If the Water Heater is installed on a roof to supply
water to the levels below, make sure that the
water pressure supplied to the Water Heater does
not drop below 199 kPa. It may be necessary to
install a pump system to ensure that the water
pressure is maintained at this level.
Check the pressure before putting the Water
Heater into operation.
If you do not supply proper pressure to the Water
Heater, noise may increase, the life of the Water
Heater will be shortened, and the Water Heater
may shut down frequently.
Potable water
• Piping and components connected to the Water
Heater shall be suitable for use with potable
water.
• Toxic chemicals, such as those used for boiler
treatment, shall not be introduced into the
potable water.
• A Water Heater used to supply potable water
may not be connected to any heating system or
components previously used with a nonpotable
water heating appliance.
Valve
When water is required in one part of the system at
a higher temperature than in the rest of the system,
means such as a mixing valve shall be installed to
temper the water to reduce the scald hazard.
7.1 Guidelines
• Use approved piping materials.
NOTE • Avoid using joints as much as
possible to keep the piping
simple.
• Avoid piping in which an air
holdup can occur.
• Avoid connection by fluid seal. It
will cause the filter to stick, that
is torn.
• Pipe and fittings must meet the installation
requirements of AS/NZS 3500.4 and local
authority regulations.
• An isolating valve must be installed on the water
inlet in close proximity to the Water Heater.
• A GATE VALVE OR BALL VALVE must be used
on the cold water inlet to the Water Heater,
THIS REQUIREMENT IS AN AUSTRALIA WIDE
REQUIREMENT UNDER THE NATIONAL PLUMBING
CODE. STOP TAPS OR COMBINATION STOP TAPS
AND NON-RETURN VALVES ARE NOT TO BE USED.
• The Water Heater needs a minimum water supply
pressure of 200 kPa to operate.
• Maximum water supply pressure must not exceed
1,000 kPa.
• If the water pressure is too high, use a Pressure
Reducing Valve and a Water Hammer Arrester.
• The unit is fitted with a pressure relief valve.
In some circumstances, there may be small
amounts of water droplets appearing from
pressure relief valve. If required pressure relief
valve should be connected to a suitable drain.
Cold water supply
(Only 32END series)
Ensure this appliance does not receive inlet
water greater than 85°C when used as a Solar
booster.
CAUTION
No pressure reduction is required unless the
water pressure exceeds 1,000 kPa.
NOTICE
Connecting water supply
• Flush water through the pipe to clean out metal
powder, sand and dirt before connecting it.
• Use a union coupling for connecting the pipes to
reduce the force applied to the piping.
