Allow stove and chimney to warm up. Insert draft gauge through predrilled hole in upper portion of fire door. Open air shutter (located on bottom of scroll between
stoker motor and gear box about ½”). Then with stoker motor running and feeding coal adjust the
barometric damper until draft gauge reads (-.02). If draft is less than a (-.02) draft with the
barometric damper closed you must close the air shutter (between gear box & stoker motor) a
little and recheck. Repeat until you obtain a (-.02) draft. If the draft is higher than (-.02)
you must adjust the barometric draft regulator. Move the weight on barometric regulator left or
right to obtain the (-.02) Recheck the draft until you obtain a (-.02).

He probably has his set up the "right" way to read a negative value.. Most of us run the tube off the wrong side so we can use the positive side of the scale to measure our negative draft pressure. That way we can see past a "negative" .05 :idea:

So they WANT a backflow in the chimney??? Somethings not adding up here ....

They said "draft" .... so with that said, I don't think you want to be in the RED zone there unless you have it hooked up backwards (hooked to HI instead of LOW). I believe the "-" refers to the black part of the scale, even though the manometer has a "-" in the red.

Either way, I'm confused ....

EDIT: Ok, that makes sense Lightning. Bit o confusion there ... :lol:

SO Wiz, if at some point you need to measure more than a -.05 just hook the tube to the other side of the gauge. Most that I've seen are used this way :D Of course thats assuming you have it hooked up the "right" way, currently..

No your right Wiz - yours is hooked backwards from mine. Mine IS hooked to LOW. My bad.

I gotta stay out of these technical discussions after a bad day and several beers .... :doh: :funny:

I had to go downstairs and check ........ and on my way down I lost my balance & jammed my fingers into the light switch ........ BRRRRRRRRZZZZZZZZZZZZAAAAAAAAPPP!!! :crazy: :wacko: :whistle:

OK, I just checked mine. Its on the LOW side.. See this way you can read your draft on the positive side of the scale, where you can see a reading anywhere between 0 and 3 inches WC.. Yours is hooked up the "right" way which is actually oppostite of mine. I'll upload a pic.. Just a second..

Yep - been a while since I looked at mine. Never realized we used them "backwards". ;)

You can see now that I have the tube on the low side so that my negative draft pressure (vacuume) is measured on the positive side of the scale, its just cooler to do it that way 8-)

Well that explains it, thought I was going nuts. Was wondering why everyone else's on positive side on Mano.

Working well, I actually was almost on target without mano. Now I'll be able to monitor stoker and tweak performance for better burns.
