VEHICLE HEATER
The auto heater is based on an extremely efficient heat exchanger consisting
of a pair of internally and externally finned aluminium diecastings.
The gas burner is at the bottom of the vertical passage that permits complete
combustion of the gas before meeting with the heat exchanger surfaces.
The combustion products travel along the top horizontal section then
downwards to further galleries while transferring their heat to the motorhome.
The flue outlet is at the bottom of the heat exchanger thus ensuring that the
majority of the heat extracted from the combustion path is completely sealed
from the living space. All the air for combustion is drawn from beneath the
motorhome through the air intake and the products of combustion are
discharged through a flue pipe to a roof-mounted terminal.
The heater is controlled by a knob mounted on the
top of the heater case which operates a thermostatic
gas valve. Ignition is by an electric re-ignition system
powered by two AA size batteries and operated by a
micro-switch mounted on the thermostatic gas control.
Operating Instructions
Before lighting the heater, ensure that the gas
supply is turned on and that the batteries have
been fitted to the ignition unit.
• Turn control knob to thermostat setting 1-10 and
press it down as far as the stop. Ignition takes
place automatically (Ignition sparking audible)
until the flame ignites.

Troubleshooting
If the fridge fails to work, check the following points before calling
a technician.
• Ensure that the correct procedure has been followed for starting the refrigerator.
• Check that the fridge is level.
• Ascertain whether it is possible to run the fridge on any of the energy sources.
• If the fridge fails to work using gas:
• Make sure the gas bottle is not empty.
• Make sure all LP gas valves are open.
• If the fridge does not work on 12V:
• Check the 12V supply is connected to the refrigerator.
• Ensure that the fuse on the 12V supply is intact.
• Check the 12V switch is on.
• If the fridge fails to work on 230V:
• Check the 230V supply is connected to the fridge.
• Make sure the fuse is intact.
If the fridge is not cold enough, it could be due to one of the following reasons:
• The ventilation is inadequate due to reduced area of the ventilation passages
(partial blockages of the grilles from wire mesh etc.)
• The evaporator is frosted up.
• The temperature control setting is incorrect.
• The gas pressure is incorrect, check the pressure regulator at the gas container.
• The ambient temperature is too high.
