Hi,
Tried to clean the contact(where the thermocouple connects to main gas
valve) and tighten it? Tried to adjust pilot flame size?
Tony

Wonderful home-repair book I have shows picture of flame-size
and -color, vs hitting thermocouple, and says to adjust
the pilot flame-size by twisting (via screwdriver) a screwhead
on the safety-thermostat body:

1: Yes, mine (honeywell) has a large screw-head available
for turning (via screwdriver), but absolutely no label
on it. How to be sure that's what it is?

2: No visible model-number on body of that safety-thermostat
plus off-pilot-ON twist knob. So can't get on net and
look for explanatory picture...

3: Worst of all, boiler-bottom is maybe three inches from floor,
and pilot-flame is higher than that, under boiler, and
thus CANNOT SEE THE DAMN THING!

I tried morror on extending-pole-thing, useless for my ability
at manipulating maglight and mirror!

(Is gas-fire/explosion likelyhood-dangerous putting
light-bulb down beneath, on floor?)

4: Plus, am 6'2" with hands to match. Tight fit.


ANY SUGGESTIONS? Especially on how to VIEW the stuff?

Also -- any TOOLS (price no issue, compared to having
plumber come by each year (on COLDEST day)) that facilitate
changing termocouple?



No, have not yet tried cleaning out connection. (Wife
worried about playing with gas apparatus & "blow up the house!")

Thanks!
