and i mean really exploded with a huge 'boom'. My husband was sitting right in front of it at the time and got covered in glass. He is crunching glass between his teeth. We went to Wood Heat and the tech is meant to be coming out on Thursday. Guess we won't be needing him now. I don't even...www.hearth.com
you replied in that post so you must of forgot about it.
Some of these can be pretty violent depending how much gas builds up in the firebox. It's in the Harman install manual that you need screws into the exhaust stub, now if some one wants to put their family at risk by not following the manufactures install procedure that's their choice.
His reply in that thread said he never heard of it happening in a pellet burner, which is what we are talking about here.
I get the occasional poor ignite, and a poof. The worst that’s ever happened is a puff of smoke pushing past the door seal. Never anything violent enough to break glass.
In any case, if the pipe isn’t fixed from movement (like wall brackets) then I’d screw it to the stove collar.
Sharpening drills is one thing I was taught in machine shop class in college. At the old house I never had a place for a bench grinder, so I learned to sharpen them with my angle grinder. They weren’t perfect but knowing the principle of attack edge and clearance, they worked pretty well. Having no money meant I had to keep what I had sharp and regrind broken ones.
