Scott, could you draw a picture or describe for a dummy what and where
the furnace face plate is. I have been thinking of the message you
quoted for a long time but wondered how to implement it.

Has anybody else performed this modification on there furnace? I did it last
weekend and it really increases your furnace out put. I did it a little
different, I cut a hole in the furnace face plate, attached a 4" flexible
duct and routed it to the junction box where the other duct goes to to split
in to two ducts. This way you are getting all the hot air in to the living
area of the EVC.

Like others, I've had problems with intermittant functioning of the
furnace. After struggling with it, buying a new battery etc. I believe
I have discovered that the problem is that Winnebago didn't install the
furnace according to specs. The manual says that a minimum of 25 sq.
inches of output ducting must be maintained throughout. Winnebago only
used one of the two output vents on the furnace, thus limiting the
output to about 13 sq. in. This single duct goes to a box which splits
it to the two ducts visible next to the back seat. This restricted air
flow causes the "sail switch" to prevent the furnace from lighting most
of the time. I replaced the cover of the furnace with a makeshift one
with another duct which vents into the rear storage area through a hole
I cut in the storage area wall. The furnace has work very reliably ever
since, even with a partially discharged coach battery and at 10000 ft.
altitude.
I plan to cantact Winnebago and urge others to also...
