9. Remove the high limit thermostat from the heater
element by cutting the three stainless steel bands
with a diagonal cutter.

fitting from the thermostat.
11. Apply high temperature pipe compound to the fitting
and install the high limit thermostat (or replacement)
fitting in the heater plate with an open ended wrench.

To Install:
13. Install new gasket onto the four threaded studs on
the steam generator.

only be installed in the correct way. This pin is on the
left of the steam generator. When properly installed,
Terminals 1, 2 and 3 are on top.
15. Install the four lockwashers on each of the threaded
studs. Install the four 1/2 inch nuts by hand to retain
