I am using view 280020 furnace-30,000 BTU, SOl-aire, in the parts book for
reference and the key numbers of the parts are in ( ).

In the process sof repairing my 1976 palmbeach I found that the outside
intake (27,27,7) and exhaust vents (28,7) for the sol-aire furnace appear to
be installed incorrectly. I do not have another one to check so thought I
would see if someone else ahs worked on one.

There is about 1" of space between the intake and exhaust ducts and the
outside of the fiberglass shell of the coach. On the outside is screwed the
cap vents directly to the fiberglass. Is this correct? It would seem that
carbon monoxide could escape into the inside of the coach when installed
like this.

Any help would be appreciated. I don't want to use it until I am sure that
it is correct. At the end of the summer I am going to install a new furnace
but want to use this one for this year.
