I have a Pensotti oil fired boiler. Sometimes (couple times a month -- as my luck has it -- really cold nights) when there is a call for heat the boiler ignites so hard that it blows itself out, not sure if they call this puffback...doesn't really make a mess but the circulators are on so the water moves through the boiler jacket it just never heats up (if the boiler blows itself out it never attempts to re-ignite -- so in the winter everytime I go away I worry about not heating the house....if no one at all is home I try to get somebody to stop by and check every day.
Called a service guy...his answer was "These Pensotti's are very quirky...if the wind is blowing and disrupts the draft this will happen" I'm no expert but that doesn't seem like much of an answer. So as far as the draft:
6" exhasut from Pensotti into a 8" chimney thimble, into a 13" x 13" chimney opening with no liner at all, just brick.
Found a Pensotti manual which speaks about having too much draft and it can cause puffback along with several other items...the Pensotti manual diagrams a handmade damper of sorts to cut down on draft...wondering if this is my issue...I'd like to go away next winter and not have to worry about my pipes...come home and the pipes will be burst and the fish tank will be a block of ice..
Any thoughts would be appreciated.
Thanks
