Propane Heater Removal

[akav8r]

I am continuing to work on my recent 82FC purchase. THANKS to the
help from the group I have knocked a couple of items off my to-do list.

Most recently I am working on removing the propane heaters (3) for
cleaning. I have the Bryant RV PDF on heater service/maint. I have
turned the gas off and disconnected the supply line at the heater,
removed the front plate with two clips, removed the two screws holding
the front of the unit to the floor and I have removed the center screw
from the intake/exhaust plate on the outside of the coach. Still the
heater will not budge from its place.

As I look into the tubes through the intake/exhaust plate from the
exterior of the coach I see a sheet metal screw protruding through
each of the tubes. It appears to be only a few inches into the tubes
and appears to be through the overlap of the heater tubes and the
intake/exhaust plate tubes. This would account for the heater not
coming out at this point. However I do not understand how to remove
these screws as even on the heater under the rear bed that is most
accesible I am unable to reach the screws from inside or out.

Has anyone else had this problem or is there something I don't
understand or know about the removal of the heaters. I don't know for
sure but I don't think these screws are original or should even be
there.

Once again THANKS in advance for any help.
