Subject: Re: SMOKE! After I turn off my BA6 Gas Heater
Content-Type: text/plain; charset=us-ascii
I went out and cleared out the space under the passenger
seat. There was nothing completely blocking the air vent,
but my K&N filter cleaning kit was kind of in front of the
opening.
I tried the BA& out, with the levers in a variety of
positions and it was working OK with no smoke. I did not
try it while driving (which is when I had my original
problem) but at the moment it looks like the partially
obstructed air intake under the seat was the culprit. The
heater is now working fine again. Does this make sense?
Thanks,
Chris
