In Reply to: Caps inslalled on boiler stacks. posted by Boiler Bob on June 13, 2005 at 19:36:27:
Hi Boiler Bob,
I visit the forum now and then seems like not as many posting as I used to see. Yours seemed a bit interesting. Is the boiler in question built with the rear of the boiler directly under the stack uptake, no breeching? If this boiler is using a stack in common with other boiler(s) it should have an outlet damper. I don't think stacks should be capped unles the boiler is decommissioned, never minding that some of them are quite high.
: Are there any rules, especially in the New England states (Maine, New Hampshire, Massachusetts, etc.) that that explain whether or not caps can be added over boiler stacks for the purpose of keeping rain from going down the stack and causing build-up at the ends of firetubes at the back of boiler? Are these allowed? If not, why? Thanks.
