• Keep the control knob pressed down for a further 10
seconds to allow the safety pilot to operate.
Attention: In the event of a fault always wait 2 minutes
before attempting to re-ignite!
If the flame goes out again reignition occurs immediately
during the closing time of the safety pilot (approx 30
seconds). If there is no flame the automatic igniter
continues to operate until the control knob is switched to 0.
If there is air in the gas supply line, it can take up to 2
minutes until there is gas available for combustion. During
this time hold the control knob down until the flame lights.
• To ensure even and rapid warm air distribution and lower
surface temperatures on the heating unit, we recommend
operating the heater with a Trumavent warm air system.
Room Thermostat
To maintain an average room temperature of about 22°C we
recommend a thermostat setting of 3-5 with the fan off, or
4-8 with the fan on.The exact thermostat setting must be
determined in each case, depending on how much heat is
needed and the design of your vehicle.
Note:
The thermostat probe is underneath the heater. Please
note that the thermostat will be adversely affected by cold
draughts from the refrigerator vents, gaps below doors etc.,
or by a deep pile carpet.Always be sure to avoid problems
of this kind, otherwise satisfactory temperature control
cannot be guaranteed.
Switching Off
Turn the control switch to 0 (the automatic ignition will switch
off at the same time). If the unit is not used for a relatively
long period of time, close off at the quick action gate valve
on the gas pipe and the gas bottle.
Changing the batteries on the automatic ignitor
If no ignition sparking can be heard, or only at intervals of
more than one second, the battery needs to be replaced.
Replace the battery only if the heater is switched off. It is
recommended that a new battery be inserted at the start
of the heating season. Remove the heater cover, push the
battery compartment cover up and change the battery.
Ensure that the polarity is correct. Close the battery
compartment.
Cautions
• At least one side of the under floor space of the motor
home must remain open at all times so there is continual
free entry of air to the under floor intake. Any build up of
snow etc must be cleared from around the vehicle.
• The heater must not be used if the flue has been
damaged.The products of combustion pass through the
flue in the wardrobe to the flue cowl.Any damage to the
flue may result in danger to the occupants.
• Avoid hanging wet clothes etc against the flue inside
the wardrobe.
• Curtains must not hang within 150mm of the sides of the
heater or within 300mm above the top of the outlet grille.
• Always wait two minutes before attempting to re-light the
heater after switching off or after a fail-safe shut down.
