vehicle
10.4.2 Truma boiler
Operating modes The boiler has three operating modes:
 Gas operation
 240 V electrical operation
 Combined operation
The operating mode is set with the operating controls.
The regulation of the water temperature in the boiler is only possible with gas
operation.
Gas operation The boiler is operated exclusively with gas.
 Never let gas escape unburned due to danger of explosion.
 When filling the fuel tank of the towing vehicle, on ferries or in the
garage, never run the boiler in gas operation. Danger of explosion!
 Never operate the boiler in gas operation in closed spaces (e.g.
garages). Danger of poisoning and suffocation!
 The water in the boiler can be heated up to 65 °C. Risk of scalding!
 Switch on the boiler and empty it if the vehicle is not used.
 Never use boiler when empty.
 If the boiler is not being used, empty it if there is any risk of frost.
 Only operate the boiler with the maximum temperature setting if you
require a large quantity of warm water. This protects the boiler against the
build-up of limescale.
 Dethleffs recommends that water from the boiler is not used as drinking
water.
 If the awning is put up and the boiler is running in gas operation, exhaust
gases from the boiler can escape into the awning area. Danger of suffo-
cation! Make sure the area is sufficiently ventilated.
 Remove cap from waste gas vent before using the Truma boiler.
