".......but is there any reason why I can't install the
knife valve flanges on the sides of the ac box?
there is pleanty of room for the flanges on the front
sides, and thus removing the two water tanks
would not be necessary. Will I still get enough
volume from the sides vrs the front?"
Although I have not performed this particular
modification I have recently had the heater fully
dismantled.
If the flanges were mounted on the front sides,
the air would have to make a 90 degree turn to
go out the new vents.Sooner or later the air has
to make the turn anyhow so I don't think it
would make a significant impact to the air flow.
Having the air make the 90 degree turn inside
the heater box may even prove more efficient
than through a bend in the hose.
I suspect one of the reasons for cutting the
openings into the front cover is that the cover
can be removed, modified and then reinstalled.
To mount the flanges to the side of the box
would probably involve doing it in the coach.
Not that difficult but a consideration.
I would want to have the front cover off anyhow
to insure that there is sufficient room inside to
permit the vents to be cut on the side of the
box without hitting the internals.
Possibly someone who has completed this
modification will comment.
