outer shell. Never grasp bare
metal without hand protection.
1. Care must be taken to pro-
tect hands during this step.
Lift outer shell straight up
as shown in Figure 5, until
all three clips engage slots
in lower shell. Screw holes
will line up at this point.
2. Lock clips into place with 3
screws as shown in Figure
5. The heater must not be
operated unless the outer
shell is properly extended
and fully locked into place.

connections for leaks
after installation or
servicing. Never use an
open flame to check for
