Wiring Diagram; Parts List - Mr. Heater MH50KT Operating Instructions And Owner's Manual

The parts lists and wiring
diagram show the heater as it
was constructed. Do not use a
heater which is different from
that shown. Heater performance
is effected by air pressure
setting. If there is any uncer-
tainty about the air pressure
setting, have it checked.
A heater which is not working
right must be repaired, but only
by a trained, experienced
service person.
