Combustion gases
If any of these conditions cannot be met, a different
location must be selected.
Surface temperature
The maximum surface temperature of the heater is less
than 85 °C, with the exception of the flue piping. No
special protection measures are required for flammable
construction materials or built-in furniture items.
Air intake
The place where the heater is to be installed must have
an adequate air supply as per AS5601.
4.3 Heater mounting
B Remove the temperature/flow selector and the gas
selector knobs.
B Unscrew the cover fixing screws.
B With a simultaneous movement forwards and
upwards, release the cover from the two lugs at the
back.
B Fix the heater vertically, using the provided screw
hooks and plugs or use fixings appropriate for the
material & weight.
4.4 Water connection
It is advisable to purge the water pipes before
connection, because the presence of dirt may reduce the
flow and, in extreme cases, cause a blockage.
B Identify the cold water pipe (Fig. 5, item A) and the
hot water pipe (Fig. 5, item B), so as to avoid any
possible cross-connection.
B Connect the water pipes to the water valve using the
connection accessories provided.

4.5 Hydrogenerator operation
The hydrogenerator (hydrodynamic generator or HDG) is
located in the water circuit between the water valve and
the heat exchanger. This component has a turbine that
rotates when water flows past its blades. This
movement is transmitted to an electric generator which
powers the heater ignition unit.
The electrical voltage value supplied by the HDG is
approximately 3.0 VAC.
Ventilation requirements as per AS5601.
Use single or twin skin flue in accordance
with AS5601.
DANGER: Make sure that all flue
connections are sealed.
B Fit the flue pipe with an approved flue
cowl.
B Failure to follow this requirement may
cause dangerous exhaust gases to enter
living space which may result in personal
injury or loss of life.
DANGER:
Every part of the flue system must be in the
vertical plane.
CAUTION:
Ensure that the flue is installed to the
requirements of AS5601, including the
requirement to terminate the flue above the
roof level.
CAUTION:
Never support the gas heater on the water
or gas connections.
CAUTION:
If fitting an isolating valve to the water inlet
line it must be a Gate or Ball Valve, a Stop
Cock or Non-Return Valve must not be
fitted.
