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
