This is the Round-Tail Spider
heater. Sort of ungainly isn't it? To be quite honest, this is
more of a dismantling, checking all parts, replacing as necessary,
cleaning and painting, reassembling rather than a complete rebuild.
A quick summary of how it
works: There are two levers - the upper solely for opening the
large upper inlet flap. This brings in fresh air.
The lower lever opens the
hot water valve and at the same time opens a second flap. Since
the heater core does not extend all the way forward. The bottom
of this forward flap moves towards the front of the heater about
1" to 1.5". If the exterior plastic flap is open, theoretically,
warm air exits into the cockpit.
Two caveats: Biba Restorations
really hasn't driven Round-Tails all that much. We fix them,
the client drives them. However this one is for BR. Therefore
we are not experts in the actual operation of these heaters.
The other caveat is that three separate '69 Spider heaters were
used in the filming of this extravaganza. The one on the right
is a clients which will unfortunately be installed as is. The
one below along with the outlet repair photos are BR's. The assembly
shots are of another client's since BR's is still somewhat disassembled.
