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. Any surfaces in contact with the Water Heater must be rated to at least 70 degrees C.
iii. The location must allow access for servicing the Water Heater.
iv. The flue terminal must be located at the side of the caravan. Acceptable flue lengths are 0.75 metres, 1.25
metres and 2 metres. A flue may be shortened to a minimum length of 0.75m, but must not be cut any
shorter than this. Flues must not be lengthened.
v. The flue terminal must be positioned at the side of the vehicle, that an awning will never be fitted to.
vi. Only the Whale flue terminal (supplied with this Water Heater) 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.
vii. 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 be a minimum of 300mm below the window.
viii. If supplied with a reset button the user must be able to access it to clear lockouts.
