INSPECTION PROCEDURE
Before starting the inspection of the generator limit thermostat, the unit must be isolated
from the electrical supply and gas supply after which the unit can be worked on as
follows:
1. Move the appliance front panel;
2. Identify the thermostat, which is found in the lower part of the generator pipe,
on the right side above the combustion chamber (see fi gure 8.3 Inspection at
generator limit thermostati on page 71);
3. Disconnect the cables (see Figure 8.3 Inspection at generator limit thermostati on
page 71);
4.
Inspect or replace the component (to disassemble the component, turn it
anti-clockwise);
