||I have a 2004 18' Roadrunner trailer made by Sun Valley Inc. (they went out of business). I purchased the trailer a couple of years ago from the original owner (retired lady)who only used it a half dozen times or so, it's like a time capsule never used inside! I was camping a couple of weeks ago and noticed the furnace looked like it was sitting cockeyed in the opening behind the grill cover. Yesterday I took the grill off and saw where the installation looked like a 2nd grader tried to get it done. The furnace sits at an angle about 2-3 inches low in the back and 2 inches to left in the back. Underneath it towards the front was a brick to help support it since it wasn't mounted squarely in the cabinet where the flange, when screwed in, would support it. The outside intake/exhaust vents are still in the factory holes and not moved, Obviously the factory installed the vents in the wrong place, then realized what happened and instead of fixing it right they jockeyed the furnace into place, shoved the vents in the back at an angle, shoved a brick under it to help support it, screwed in 2 out of the 6 mounting holes in the flange, put the front grill on to hide it and sent it out for sale!!!
Here's my question, does anybody know of any reason why I wouldn't be able to cut out a section of the vent pipes, replace it with flexible galvanized exhaust pipe and put it back together the correct way? This way I don't have to cut the trailer skin to relocate the vent cover and try to find matching aluminum siding. The 2 vent pipes would have an "s" bend that goes up 2-3 inches and to the side about 2 inches and mount correctly on the back of the furnace.which would be installed flush to the cabinet as it should have been. The furnace is a Surburban NT-20SE.
Any thoughts, comments or suggestions for a better fix are welcome.
