berglass particles are present. Disconnect the blue con-
nector on white Hi-Temp wire from purple connector on
white wire coming from the Variable Speed Control.

Run the 2 Hi-Temp wires down the side. Place magnetic

Assembly panel in rebox oor. This may also need to be done in conjunction with gas line installation.
