IR ELEMENT AND CATALYTIC CONVERTER
Removing and Installing the Catalytic Converter
1. Remove the IR Element.
2. Once the IR Element has been removed, remove
the Catalytic Converter Clip (Item135) to access
the Catalytic Converter. Figure 34.
: It may be necessary to remove the
Blower Motor Assembly (see page 41) to get
access to the top of the Catalytic Converter.
This will allow the Catalytic Converter to be
pushed down out of the housing. Figure 34.
3. Remove the Catalytic Converter (Item 136).
4. Install a new Catalytic Converter.
Installing a new IR Element
1. Gently squeeze the new IR Element together in
order to get the Terminals and Lead Wires into
the cavity and through the mounting holes.
: Do not allow the Thermocouple
Lead Wires to kink. They are solid wire and
will break.
2. Once the IR Element is installed, expand the IR
Element in order to reinstall the Shim Washers
(Item 131) and Snap Rings (Item130). Figure 34.
: Be sure that the Snap Rings sit in the
grooves on IR Element.
3. Reconnect the IR Element Lead Wires to the
EMI Filter and the High-Limit Thermostat.
4. Reconnect the IR Thermocouple Lead Wires
to the Thermocouple Extension Wires – Yellow
to Yellow and Red to Red.
