Step 1 Find suitable location for water heater installation
Consider the following 10 points:
i. For weight distribution in caravans, the Water Heater must be positioned as close to the axle as possible.
The installer must avoid locating the Water Heater at the very rear and the very front of the vehicle.
ii. Ensure the pressure relief valve / discharge pipe can be located through the floor without fouling chassis
members etc.
iii If the Water Heater is installed in a raised position, the drain valve must be installed at the lowest
position in the water system, to achieve effective draining. To achieve this, remove the drain valve from the
Water Heater and relocate it, near the Water Heater in the lowest position between the Water Heater and the
non-return valve (if one is fitted), in the water system. Make sure the water system cannot create air locks
that would prevent the Water Heater and the full system from draining.
Ensure that any surfaces in contact with the Water Heater are rated to at least 70 o C.
iv.
v. Ensure that the location allows access for servicing the Water Heater.
vi. In selecting the Water Heater location, ensure that the flue terminal will be located on a flat and exposed
outside surface, avoiding trim strips.
vii. Ensure that the flue terminal can be positioned at the side of the vehicle that an awning will never be
fitted to.
viii. Only the supplied flue terminal is permitted to be used in conjunction with this Water Heater. This flue
must not be positioned within 500mm of a refuelling point or fuel tank breather outlet or any ventilator from
the fuel system(s). The flue terminal must not be fitted within 300mm of a ventilator for the living space or an
opening part of a window.
Fuel refuelling / breather vent
ix. The flue terminal must only be positioned vertically below an opening part of a window if the appliance is
fitted with an automatic shut-off device to prevent operation when the window is open. The flue terminal
must still be a minimum of 300mm below the window.
x. The user must have access to the reset button located at the front of the appliance beside the wiring
harness connection.
Step 2 Cut out hole for flue
See the flue template (WH0822 only).
Position template on the inside of the wall with side 'A' visible, then drill hole at centre position marked 'X' on the
template.
Position the template on the outside of the
wall with side B visible, locate over the
drilled position hole 'X', and ensure the
template is level.
