GAS CONNECTION
Fit a union to the Bosch solar booster gas inlet for easy connection and removal. The thread
diameter is 18 mm.
THIS DOES NOT INDICATE THE SIZE OF THE GAS SUPPLY.
(2)
Fit an AGA approved isolating gas cock in the supply line adjacent to the water heater
gas connection.
(3)
Ensure that the supply pipe and the gas pressure regulator (LPG or Natural Gas) has
sufficient flow capacity for this and other appliances connected to the fitting line.
(4)
For LPG appliances ensure that gas cylinders are of sufficient size. The water heater
alone will require 2 x 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.
Ensure that the gas pipe size is correct. If undersized the appliance will not operate
correctly
SERVICE CALLS ARE CHARGEABLE FOR UNITS WITH INCORRECT PIPE SIZES OR
BLOCKED GAS OR WATER FILTERS.
CONNECTION FROM SOLAR STORAGE TANK TO BOOSTER
Refer to technical sheet for position of connections. The WATER INLET connection is 18 mm
¾"
BSP and requires a union to allow for removal of the water heater. Pipe sizing from the
solar storage tank should be sized according to local BY LAWS for water supply.
ISOLATING GATE VALVE
A GATE VALVE OR BALL VALVE must be used on the inlet to the solar booster. 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.
N.B.
NO PRESSURE REDUCTION VALVE IS REQUIRED UNLESS THE WATER
PRESSURE EXCEEDS 1000 KPA
HOT WATER CONNECTION TO SOLAR BOOSTER.
Refer to Technical Sheet for position of connection. The outlet connection from the tank is 18
mm (¾" BSP) FEMALE thread, and requires an isolating valve & union at the booster to allow
for removal of the unit.
Keep the pipe lengths to a minimum, and make sure that the pipework is well insulated as
correct performance of the appliance is dependent on properly insulated pipework.
DO NOT FIT ANY VALVES OR RESTRICTORS TO THE OUTLET OF THE BOOSTER
DO NOT FIT ANY OBSTRUCTION TO THE PRESSURE RELIEF LOCATED ON THE HOT
WATER OUTLET CONNECTION.
After purging the air from the system using the hot water supply taps, isolate the water supply,
remove the water inlet strainer located on the water supply inlet connection of the booster.
Remove any debris from the filter and replace. When replacing the filter, do not over-tighten
the “O” ring seal.
