Function description
The liquid gas heater ‘Truma Combi’ is a warm-
air heater with integrated hot water boiler
(10 litre volume). The burner operates fan-
supported, which ensures trouble-free function
even when on the move.
In winter operation the heater can be used to
heat the room and simultaneously warm water.
If only warm water is required, select
summer operation.
– In summer operation, the water contents
are heated in the smallest burner stage. Once
the water temperature is reached, the burner
switches off.
– In winter operation, the unit automatically
selects the required power setting according
to the temperature difference between the
temperature set on the control panel and the
current room temperature. When the boiler is
filled, the water is automatically heated as well.
The water temperature depends on the selected
operational mode and the heater output.
At a temperature of approximately 3° C at the
automatic FrostControl safety/drain valve, the
valve will open and drain the boiler.
The unit is not suitable for use as a flow heater.
Safety instructions
If the gas system is leaking or if there is a
smell of gas:
– extinguish all open flames
– open windows and door
– close all quick-acting valves and gas cylinders
– do not smoke
– do not activate any electric switches
– ask an expert to inspect the entire system!
Repairs may only be carried out by an
expert!
Any modifications to the unit, including
accessories, exhaust duct, and cowl, or the
use of spare parts and accessories that are
important to the operation of the system
that are not original Truma parts and failure
to follow the installation and operating
instructions will cancel the warranty and
indemnify Truma from any liability claims. It
also becomes illegal to use the appliance, and
in some countries this even makes it illegal to
use the vehicle.
The gas supply’s operating pressure (30 mbar)
must be the same as the unit’s operating
pressure (see type plate).
The vehicle owner is always responsible for
arranging the inspection.
Liquid gas equipment may not be used when
refueling, in multi-storey car parks, in garages,
or on ferries.
