HEATING AND WARM WATER WITH BOTH
230V HEATING CARTRIDGE AND LPG
BOILER
For use only when electricity or gas alone is
not sufficient.
1. Ensure that the gas supply is connected
and all relevant valves (bottle, manifold)
are open.
2. Set the SC20 ‘Circulating Pump Switch’
to on.
3. Set the SC20 ‘Gas Burner on/off’ switch
to on.
4. Switch the SC20 ‘1kW heating element
on/off’ switch and ‘2kW heating element
on/off’ switches together to select a total
of 1kW, 2kW or 3kW as desired, taking
into account the 230V supply available to
the caravan. (See appliance consumption
figures elsewhere in this manual)
5. Use the TP5000 programmable room
thermostat to determine heating operating
times and desired room temperature.
SWITCHING OFF THE LPG BOILER,
HEATING CARTRIDGE AND CIRCULATION
PUMP
1. Set the SC20 ‘Circulating pump’, ‘Gas
burner’, ‘1kW heating element’ and 2kW
heating element’ switches to off.
2. Switch off the 230V fused isolator located
close to the boiler if the vehicle is not to
be used. If this switch is not set to off, the
boiler will remain in the standby position
and use a small amount of electricity.
3. For LPG isolation set the manifold or gas
bottle valves to off.
IF THE RED LIGHT COMES ON
The boiler is fitted with an ionised flame
sensor. This means that if the flame goes out
for some reason, the electronics will attempt
to re-light it. If the flame is not re-lit within
ten seconds, a solenoid valve within the
boiler switches off the gas supply, the
electronics are ‘blocked’, and the fault
warning LED on the SC20 panel will
illuminate. The electronics must be re-set
before the boiler can be started.
RESETTING FROM THE BLOCKED
POSITION
Switch the SC20 ‘gas burner’ switch to off.
The fault warning light will go out.
Wait for approx. 30 seconds while the
electronics re-set the block.
Set the SC ‘gas burner on/off’ switch back to
on – The electronics will once again attempt
to re-start the boiler.
