>Ron,
> I and Camping World installed a Suburban SF30 furnace in my '75 PB a
>few months ago. (I think it was the first GMC he ever worked on). First, the
>back of the furnace must be closed off with a piece of sheet metal and
>allowing holes for the intake and exhaust pipes. Then, Max, of Buskirk, told
>me he builds a platform 4 1/2" high which is the height of the bottom of the
>door under the sink. I figured he knew what he was doing, so I made a plywood
>platform which was fastened to the floor inside the cabinet. Mounting the
>furnace on this platform took care of the sloping wall problem by making the
>dimension to the outside wall long enough to accomodate the furnace body and
>eliminating any need to install the furnace on a slope. Two holes were
>drilled with a hole saw for the two pipes and there is enough extension of
>them to fit to the outside. The trim plates that came with the new furnace
>fit because you're now up high enough on the side to be above the curve of
>the coach wall and I think they look good. The holes from the old Solair
>pipes were sealed and the old trim plate put on which also looks good and
>avoids a patch and paint job on the side of the coach. Next came the ducts.
>My Suburban had four 4" outlets - two on each side, one above the other. The
>ducts as CW installed them are too close to the couch on one side and take up
>all of the lower cabinet on the other side. If you remove the front panel of
>the Suburban, you will see there is provision for feeding the ducts from a 3
>1/2" x 10" opening in the bottom. I had made a "U" shaped plenum with two
>outlet openings on each leg which can be fitted and attached under the
>furnace and between the cabinet base board and the 4 1/2" platform. The ducts
>can then be kept flat on the floor and do not rub the couch or obstruct the
>cabinet. I don't know whether this is clear and one of these days, I'll get
>some pictures. The Suburban is really a tight fit when installed where the
>old Solair was on my PB. Other models may be different, but this is what I've
>done.
