    Common Draft Regulator ?

    Two Boilers,one draft reg , is this o.k.? Both boilers are the same, flue is 8" ,boiler "A" has priority over boiler"B" ."A" boiler flue goes up 2',then 90's horizontal to the right for 2',then an 8" regulator,then 2', then a T,the bull goes down to boiler "B", the run of the T goes to the chimney.I was on a "look-see" so I had no test tools with me.When boiler "B" fired the draft regulator did swing in and out,so ,maybe??Tomorrow or the next day will tell ,when I'll have my truck,tools and test stuff !!! Thanks
