Working on sealing up leak points before the weather turns.
Yesterday I started on the furnace
vent, while finishing up the stove vent.
is a Hydro Flame BRC 10A. I believe it is original to the Boler
, and it is working fine.
I am having a hard time removing the back of the furnace
, what I am going to call the exhaust vent. Took the cover off, loosened the putty tape, and removed the blocking from the back of the furnace (through the fridge
vent which is just above).
The exhaust vent is connected to the furnace by a larger (approx 8" diameter) vent box metal tube, and inside of that is a smaller (approx 4 " diameter) vent cap metal tube. Both are connected directly to the furnace by sliding into it. It is clear where the larger vent box tube connects to the furnace and that loosens easily. I cannot see or feel where the inside vent cap tube connects. It is rusty and can't be budged. I have tried WD-40, and various wedges and tools to try to loosen this connection. All I've accomplished is a bit of bending of the vent cap assembly.
In this thread Yvon Chayer's description is similar to what I see in mine: http://www.fiberglassrv.com/forums/f...ver-74517.html
According to the Installation Instructions for this furnace the small tube is the inserted into the large tube as the last outside step. Fiberglass RV - Document Center - BRC-10 Hydro Flame Gravity Feed Furnace - Install
Looks like TimR had this problem as well. I PM'ed him but haven't heard back. http://www.fiberglassrv.com/forums/f...val-70214.html
Looking for creative ideas I may not have thought of yet. As the furnace works and I would need to bust it to get it out, if I can't disconnect it I will clean it as best I can and jam new putty tape in.
