[VAC] Re: replacement heater (for 70's coaches)

[Chris Bryant <bryantrv@xxxxxxxxxx>]

         As other have said- it does need to be "gas tight"- the object is 
to have all of the combustion products vented to the outside. For a while 
we were doing tests on a recalled Hydroflame furnace that involved putting 
LP gas into the chamber, and checking for leaks with a combustible gas 
detector- so they do have to be pressure tight.

         The new Suburban furnaces have telescoping inlet and outlet tubes- 
the outside edge does *not* have to be flush against the outside skin.
