Question

Hi I have a dometic RM4200 fridge when I fire it up on gas I keep getting a flame shooting out of the 2 holes before the burner when I removed the flue the burner operates fine any help please

Answer

Suggest you do the following-
Clean the flue with a wire brush.
Check the pressure output of the gas regulator - the one on the gas bottle.
Change the pilot jet in the fridge - our ref. 127390
