Frequently Asked Questions
Q: How do I ignite the burner on the Truma S 2200 heater?
Open the gas cylinder and the quick-acting valve, turn the control knob to the spark symbol, press it down fully for a maximum of 30 seconds, check the flame through the viewing window, keep the knob pressed down for about another 10 seconds after ignition, and after a minute switch to high output.
Q: What batteries should be used in the automatic igniter?
Only fit leak-proof 1.5 V AA-size (Mignon, LR6/AM3) batteries rated for heat up to +70 °C - Truma part number 30030-99200.
Q: Can the heater be operated while driving?
Heating on the move needs a safety shut-off device that meets UN ECE Directive R 122 (for example a MonoControl CS gas pressure regulator). Without one, the gas cylinder must be turned off while you drive.
Q: I can smell gas - what should I do?
Remove every ignition source: put out naked flames, don't use electrical switches, phones or radios, don't start the engine or any appliance, and don't smoke. Open the windows and doors, get everyone out of the vehicle, turn off the gas cylinders or supply from outside, and have experts check and repair the whole gas system.
Q: How do I ignite the burner?
Make sure the auto-ignitor has a fresh battery and any cowl cover is off, open the gas cylinder and the quick-acting valve in the supply line, turn the knob to the spark symbol and push it fully in for up to 30 seconds until it lights. Keep it held for 10 seconds more, then leave it on the ignition setting for around a minute before turning it to High.
