Specifications

Truma Combi 4E / Truma Combi 6E
The Combi E gas heater is a warm air heater
with an integrated hot water boiler.
The unit can operate on liquid gas (LPG)
or 230V mains electricity.
The heater can be used in ‘winter’ mode that
will produce warm air heating and hot water,
and ‘summer’ mode that will produce hot
water only.
Before operating the heater for the first time
ensure that the 12V system is turned ‘ON’
on the control panel over the doorway,
and that the gas cylinder, and isolation
valve are turned on.
To use the heater on 230V the motorhome
must be plugged into the mains supply,
with the isolation switch in the ‘ON’ position.
