Replacing the Thermocouple
Important: Use only a factory authorized thermocouple
for replacement.
1.
Remove the manifold assembly as directed
previously.
2. Remove the retainer clip from the back of the
two piece wire connector. Remove the two piece
wire connector from the manifold door. Remove
the thermocouple (Figure 22).
3. Pull the thermocouple from the pilot assembly.
(Figure 21 and 24).
4. Push the new thermocouple through the holes in
the pilot bracket. (Thermocouple tube must be
positioned below the pilot bracket.) Insert the
thermocouple tube into the holes provided in the
pilot assembly until it clicks into place.
5. Position the new thermocouple through the larger
opening of the two piece wire connector (Figure
22). Be sure igniter wire is positioned through the
small opening of the two piece wire connector.
6. See “Replacing Manifold Assembly” at the top of
next column.

Replacing the Manifold Assembly
1. Check the door gasket for damage or imbedded
debris prior to installation.
2. Insert the manifold
assembly into the
burner compartment
making sure that tip
of the manifold tube
engages with the slot
in the bracket inside
the combustion
chamber (Figure 23).
3. Inspect the door
gasket and make sure there is no fiberglass
insulation between the gasket and the
combustion chamber.
4. Inspect the viewport for damage and replace as
required.
