Step 27
Install combustion cham-
ber
The combustion chamber
material is fragile, and can be
cracked or gouged with in-
correct handling. HANDLE
CAREFULLY! DO NOT
use the chamber if it is dam-
aged.
Use of an approved dust
respirator is strongly recom-
mended when handling the
insulating components of the
boiler.
1. Insert the chamber into the top of the
section assembly as shown.
2. Position the chamber with the
ROUND hole toward the front and the
SQUARE hole to the rear.
3. The combustion chamber should sit
evenly in the opening, with its FLAT
surface facing up and even with the
surface of the sections.
Step 28
Position the burner gasket
Use of an approved dust
respirator is strongly recom-
mended when handling the
insulating components of the
boiler.
1. Carefully place the burner gasket
on the surface of the combustion
chamber.
Step 29
Apply Resbond adhesive
to the burner gasket
Rubber gloves are recom-
mended for this procedure.
1. Apply a generous bead of Resbond
adhesive (supplied with boiler)
around the entire burner gasket.
2. Position the bead in the center of the
gasket.
3. This adhesive will bond the gasket
to the burner when the burner is
installed.
