- An overheat label is located on the clean-out cover of the steam generator. The triangle in
the center of the label, as shown below, is normally gold color. This triangle turns black at
450° F, indicating that the generator has overheated at least once. The operating
temperature of the generator should be between 350° and 400° F. If it is not, the thermostat
should be replaced.
Note: the overheat label will not return to its original gold color once it has turned black. It should
be scraped off and replaced so that the thermostat can be monitored at all times. In addition, in the
event that the thermostat has to be replaced, it is important to replace the label immediately after-
wards so that someone at a later inspection will not suspect a faulty thermostat.
3. To Remove.
- Disconnect the water riser tube.
- Disconnect electric wiring at the two terminals.
- Remove 16 hex nuts. Note: Remove food drawer and hold screws up to prevent turning.
- Lift off generator.
4. To Replace.
- Remove the old gaskets from the discharge plate and scrape residue silicon and lime de-
posits from the discharge plate. Clean the groove of the discharge plate. To install the new gaskets
in the discharge plate grooves, as shown in Figure 2. Place discharge plate on the steamer (gasket
facing towards generator) so that steam holes line up with the twelve round holes in steam chamber.
Place the generator on the above assembly so that mounting holes line up with the sixteen round
holes in the discharge plate. Tape the carriage bolts in place from inside steam chamber and then
tighten the nuts with lock washers. Remove all tape. Place casting on plate carefully so that holes
align properly. Replace screws and tighten securely. Apply a bead of RTV around the edges of the
discharge plate and steamer. Allow the RTV to set approximately 24 hours before operating unit.
