in THE MAIN WALL
Burnham installation manual says draft regulator should be a minimum of 18 inches above top of boiler in flue pipe. Our's is about 4 inches above boiler. Any ideas on this? I notice it never opens just bangs in and out about a quarter of an inch when burner is on.

    How far the regulator opens

    depends on the chimney draft and the way the regulator is adjusted. It's hard to say whether yours is OK without measurements from a draft gauge. A pro can do this for you.

    Q?

    In that 4" above the boiler, how much on center is the horizontal measurement? Sounds like you were hurting for head room to install this damper. Call,,,,,,,,and find out what the draft should read before the barometric relief damper. Chimney draw is also critical and ultimately will determine the final -press reading. There should be no problem installing it in a horizontal run AS LONG as the proper draft can be obtained
