George,

The Westfalia Dometic fridge should not blow out while driving or in a strong wind or
while driving in a strong wind. If it does, then there is probably one of two things
wrong:
1) Both the air inlet pipe to the combustion chamber and the combustion exhaust pipe
from the combustion chamber must be exactly the same length. If not, differential
pressures at the vent will cause excess air to flow down one or the other of the two
pipes and blow out the flame. If you must shorten one hose then shorten the other to
match.
2) The vent on the outside must not have any leaks around the rubber gasket; the
gasket must have the dimple facing forwards; and the metal dish with the hole in the
middle must be fastened securely to the exhaust pipe and held firmly in place by the
chrome cap. If anything is loose or misaligned then excess air may flow down one of
the two pipes and blow out the flame.

Keep the flame burning. Larry
