How Does the Truma Combi Work?
1 Control panel
2 Gas connection
3 Solenoid valve
4 Combined combustion air/exhaust cowl
5 Combustion air fan
6 Gas burner
7 Ignition electrode
8 Combustion chamber
9 Flame tube with baffle
10 Combustion air fan
11 Heat exchanger
12 Electric heating elements
13 Four warm air outlets
14 Stainless steel water container,10 litres
15 Hot water connection pipe
16 Cold water connection pipe
17 Room temperature sensor
18 HDF thermal jacketThe furnace is switched on and the required temperature for heating and warm water is set on the Truma Combi LCD control panel (1). The gas supply to the furnace is controlled by the solenoid valve (3). The necessary combustion air flows through the outer pipe of the combined inlet for combustion air/outlet for exhaust (4) into the furnace and is transported into the gas burner (6) with the help of the combustion air motor (5). The gas burner ignites the gas-air mixture in the combustion chamber (8).
The hot exhaust gases are deflected at the end of the combustion chamber on the baffle plate of the flame tube (9) and flow back between the burner's flame tube and the inner wall of the heat exchanger. They leave the furnace through the exhaust outlet (4).
The circulation air fan (10) feeds the air to be heated into the device. The air flows along the heat exchanger (11) ribs, which ensure optimum heat transfer with their large transfer surface. Additional electric heating elements (12) are situated in the heat exchanger. Water and/or air can be alternatively or additionally heated by them. The warm air is then distributed in the vehicle via four warm air outlets (13). The fresh water is located in the outer stainless steel water container (14). It is heated by heat transfer from the heat exchanger (11).
