INST 318 HINRG HEATER – V01-18
Do not
install spa
blowers in the
same room as
a gas heater. This is potentially dangerous to spa users.
Do not store chemicals or fuel in the same room as the gas heater. This may cause fire or explosion. When installing in a
garage the HiNRG Series Heater must be installed 450 mm above floor level.
ELECTRICAL CONNECTION
The heater is supplied with a standard 10 amp 3 pin plug for connection to a 240V 10 amp GPO. All pool or spa equipment
connected to mains power should be protected by an RCD circuit breaker.
GAS CONNECTION
175/250/400 MODELS:
The gas connection is on the left side of the heater. A 20mm FI. connection is provided for gas line connection. An approved manual
shut off valve must be installed in the gas fitting line before the heater.
The gas fitting line should be installed by an authorized person and comply with local regulations and Australian Standard code
AS/NZ 5601. The gas line from the meter will usually be of a larger size than the gas inlet connection.
The heater gas valve has a built in pressure regulator and 2 x ⅛” pressure test points. On starting the heater, a manometer must be
used and the supply inlet pressure checked while the heater is running against the heater data plate. Incorrect inlet pressures may
void warranty and may result in service charges, should service be required. Gas valves are pre-set and should only be adjusted by
trained Astral Pool technicians or qualified gas fitters.
WATER PRESSURE SWITCH ADJUSTMENT
The HiNRG Pool Heater incorporates a water pressure switch which allows the burner to operate only when the circulating pump is
operating. The pressure switch is designed to operate with the heater installed up to 3 metres above or below the surface level of
the pool or spa.
