Using the heating cartridge
Electrical operation is selected on the control
panel, the 12-volt relays on the circuit board
trip, allowing the 230 volt supply to reach the
electrical elements.
The heating cartridge is controlled in the same
way as the gas boiler.
Warm water
When only warm water is required, for example
during the summer, no settings need to be
made, the boiler will look after this function
automatically.
The pump will only start when the temperature
in the vehicle is lower than the set temperature
(see item 4, Control Panel). If the vehicle
temperature is higher, the pump will not start.
Important information
• The boiler must not be started if there is no
glycol in the system.
• The LPG boiler and heating cartridge may be
operated in parallel.
• The heating system may be heated up
without the warm water heater being filled
with fresh water.
• Always switch off the main isolator for the
boiler when the vehicle is not being used.
• Always drain the warm water heater of fresh
water if there is a risk of frost.
• The LPG boiler must not be operated when
refuelling the vehicle.
• When washing the vehicle, take care not to
get water in the venting.
!
WARNING:
Care should be taken
to ensure adequate ventilation of the flue
at all times. Its is inadvisable to inhale
exhaust fumes.
The Domestic hot water heater
The boiler is fitted with a built-in warm water
heater with a volume of approx. 8.5-litres fresh
water. The warm water heater can produce
around 12 litres of 40°C water per half-hour
(at a cold water temperature of 10°C). If the
heating cartridges are used instead of gas
for heating the boiler, the capacity is slightly
reduced. Always rinse out the heater before
it is used, particularly if it has not been in
operation for some time.
Note:
The hot water is not intended for
drinking or cooking.
When the heater is in continuous use, it should
be emptied approx. once a month, to ensure
that a new air cushion is formed in the heater.
The air cushion is essential for absorbing
pressure surges in the heater.
Note:
The warm water heater should
always be drained of fresh water when there
is a risk of frost and when the caravan is not
in use.
The warranty does not cover frost damage.
Draining the heater using the combined
safety/drain valve:
1. Switch off the freshwater pump
2. Open all water taps.
3. Then open the safety/drain valve by raising
the yellow lever (M) to a vertical position.
4. The heater will now drain directly below
the vehicle through the safety/drain valve
hose. Check that all the water is emptied out
(about 7-10 litres). Leave the valve in the open
position until the next time the heater is used.
Note:
Check that the automatic check valve
(N) is open and is allowing air to enter the
heater when it is being drained, and that the
hose (O) is not blocked.
