Replacing the Thermal Switches
Follow the steps below to replace either of the thermal switches.
When disconnecting each wire, we recommend marking the wire to
ensure they are reconnected in the correct locations.
Step 1:
Disconnect power and gas supply to the fireplace.
Step 2:
Remove glass barriers. See
Section 10
for installation and
removal of glass. Note: it is possible to remove just one side of glass
from the appliance when replacing a thermal switch. Always take
precautions against dirt and damage to glass while servicing.
Step 3:
Remove the screws securing the firebox baffle. It is possible to
remove the thermal switch mounting bracket with one baffle removed.
