Manometer settings recommended by Hitzer?

PostBy: Bobs86GN On: Thu Sep 04, 2008 8:51 pm

Does Hitzer actually have a recommended manometer reading for a 50-93 hand fired stove? I can't seem to find it anywhere. I just received my Dwyer #25. Not cold enough yet to fire it up but I can't seem to decide what setting is best even with reading all the posts. I read all kinds of numbers in various posts and I'm more confused than what is normal for me. :oops: My old Hydrafire boiler also does not have the info I need in the paperwork (28 yrs old). It is also hand fired. I assume you get a hot fire cranking and then adjust the baro to limit the reading to whatever # is recommended right? If Hitzer doesn't actually recommend a setting is there some kind of consensus on what I should use for a setting? Also, is there a consensus for a setting for my boiler?
This is the boiler I am using.

A good starting point for most hand fired stoves is .05-.07"wc Any more draft and you are pulling too much heat up the chimney, much less and you may not have enough air being pulled through the coal bed.

Same figures for the boiler as well? And if there are no issues at those settings is it worthwhile to try to tweak them down further?

I doubt if there is any measurable fuel savings or increase in heat output between say .05" and .07". The main function of a barometric damper is to keep the draft fairly steady within a range of draft. This is to even out the wide swings in draft that make it difficult to control the burn rate.. The minor adjustments can be made with the combustion air control.

It certainly doesn't hurt to experiment a bit with the draft, since every instalation is different, you may find a setting that is a 'sweet spot' for your instal.

My instructions that came with my model 82 said .06. The instructions seemed pretty generic for there various models.
