Replacing the Thermocouple
Important: Use only a factory authorized Flame
®
Guard Safety System 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 and remove the two piece
wire connector from the manifold door (Figure 24).
3. Pull the thermocouple from the pilot assembly
(Figures 28A and 28B).
Be careful not to bend or alter the position of the
pilot assembly components.
4. Push the new thermocouple through the holes in
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
24). Note: Thermocouple contains a thermal
fuse. Do not bend in the location shown below
(Figure 25). Be sure igniter wire is positioned
through the small opening of the two piece wire
connector.
6. See “Replacing Manifold Assembly” Page 23.
Notice: The thermocouple contains a thermal fuse,
which is used as a safety device.
