WARNING - Ensure power is turned off before removing any TCO.
There are two thermal cutouts: one in the LH room fan assembly (60°C) and the other attached to
the exhaust manifold (120°C).
Exhaust TCO (120°C)
Access to this TCO can be made by following steps 1 to 2 from section “S10 Pressure Switch
Removal” on page 61. Remove the 10 screws (shown in the diagram below) in the access hatch
and carefully remove from the firebox.
Reach in to the hatch and locate the TCO (circled in the diagram below). The TCO has two wires
connected to the main body; remove these. Unscrew the TCO using your hand and remove from
the firebox.
