Yes it was the valve. Very pricey touch. I went looking online and the valve is at least $250 plus shipping to Canada, which according to UPS apparently near the moon. Joe at Outback / Trillium
installed a new valve for $450, including the valve. Not bad seeing as he spent hours getting the exhaust apart. I think he gave me a deal.
Yeah, that's allot of cash for a rusty, 34 year old furnace
. But, before I discovered all the other great things about a Trillium
4500, I really liked the idea of a gravity furnace
. And especially the one on a 4500. And I likely would have spent more on a new one, that I don't like as much. Other then the valve, not much to go wrong. The burner and all other steal shows just a thin and spotty layer of rust.
A question for those in the know. Do I paint
the burner and or fire box with anything, or just leave it alone?
Attached are pictures of the vent re-build. Or, as I like to call it, the Fannkin Vent. Notice that I still have the same problem with fit that I had before. The top of the vent is about an 1/8" out from the bottom. The top row of hole go into the bottom of the closet. Otherwise I would do what I am going to do with the rest of the holes, which is using a stainless steel bar, 1/16" thick or so, and 1/2" wide. Use it as a large washer for stainless nyloc nuts on stainless counter sunk bolts.
I tried to pound the vent with a pry bar and a hammer, (yes I wore safety glasses). But I just don't have the knack for metal bashing. I can live with the damage I did to the vent. Now I am thinking gasket. Any recommendations?
