turbotom wrote:"mano gauge", like what used to measure propane flow when setting up a propane burner? is this something inexpensive? definitely want to fix the check damper, just not sure how ill go about it, im hoping someone will chime in with some parts....? love this forum, great stuff here.
A mano gauge can measure very slight differences in gas pressure, such as the lower pressure inside the flue we call "draft", compared to room air pressure.
If you do a search you'll find lots of info on how to set up and use them, plus what people are observing about their stoves to help adjust the dampers to get the maximum safe heat output. This Mark 2 model by Dwyer is the most common one used by the guys on here (cause like many of us, it's the cheapest one that works well ! ). http://www.amazon.com/dp/B009PAN3C8/ref=biss_dp_t_asn
The check draft plate knob's shaft looks like it's simply peened over on the inside of the plate. A new plate can be made by cutting some 1/8 inch sheet steel to size, bend a matching curve in it, drill the plate and refasten the handle to it.
