Step 1 Find Suitable Location For Water Heater Installation
Consider the following 7 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. Ensure that any surfaces in contact with the Water Heater are rated to at least 70 degrees C.
iv. Ensure that the location allows access for servicing the Water Heater.
v. In selecting the Water Heater location, ensure that the flue terminal will be located on a flat and
exposed outside surface, avoiding trim strips.
vi. The flue terminal must be positioned at the side of the vehicle that an awning will never be fitted to.
vii. Only the supplied flue terminal is permitted to be used in conjunction with this Water Heater. This flue
must not be positioned within 300mm 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.

Diagram
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.
Step 2 Cut Out Hole For Flue
See the flue template supplied with the Water Heater.
i) Position template on the inside of the wall with side ‘A’ visible, then drill hole at centre position marked ‘X’ on the
template.
ii) 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. Ensure that the flue outline is on a flat surface avoiding trim strips etc.
If the flue needs mounted in a higher position, the Water Heater mounting board can be raised to suit provided there
is sufficient height available.
iii) Drill four 6mm corner holes and cut aperture using flue template (provided) as a guide.
