I recently put a 10-20K btu in my family room. Overall I am happy with it but
occasionally it will lose its pilot. It makes a sputtering noise when the
burner is on and the noise comes from the pilot. It is like a bunsun burner
that has too much air. I looked at the pilot and do not see any choke
mechanism at all. I have emailed the manu. with no result. I have tried to
phone them and it is always busy. Anyone have any suggestions as the the
problem and cure? Thanks, RW
This is a long shot, but I wonder if there could be some moisture
in the line. Did you put a drip leg in the line just before the
Anyway, disconnect the gas line and blow it out. I think I would
disconnect the pilot burner and blow it out with compressed air too.
(Don't blow compressed air thru the gas control!)
Over the years I ran across this in my garage heater, and my (and me)
neighbors in their home furnaces.
The pilot flame had a "roaring, spitting" sound, and a downdraft would
occassionally blow the pilot out
Looking at it carefully, they had the pilot flame just roaring away, just
touching the thermocouple.
Just barely keeping it warm.
Along would come a downdraft or gust of wind, and blow the pilot flame
sideways (or down) a bit, and cool off the thermocouple.
Immediately, the whole thing would shut down.
The pilot flame was blowing outward so darn hard, it was barely enveloping
the thermocouple, and almost blowing itself out. The raw gas was enveloping
the theromcouple (mainly), and the (warming) flame was almost (past) the
What we did on about 5 furnaces, was to unscrew off the small protective
adjustment (cap) on the gas valve, use a small screwdriver, and adjust the
standing pilot size, where it was a nice, soft flame, enveloping the
thermocouple, and there will be no roaring sound anymore. Then we replaced
the protective cap.
Now gusts of wind do not allow the "wide, soft" flame to blow away from the
These were done about 1970 or 1980, and haven't had a problem since.
If you don't know how to do this, then definitely have someone do it, who is
It's not rocket science, just that (I'm) very, very careful with Gas,
especially if I will be sleeping around it.

Sounds like the ODS is dirty. The ODS is where the pilot flame comes out.
Take a can of compressed air like what is used to clean computers and blow
out the ODS. Blow it first from the two small holes in the sides toward the
back. Then back down where the pilot flame comes out.
