Installing the Mounting Bracket
Use this procedure to install the mounting hardware in
preparation for installing the burner.
NOTE:
If possible, do this work before (or in the very early
stages of) furnace heat-up.
1. Install the burner mounting bracket (21) with gasket
on the precombustor using four T-bolts, washers, and
nuts (23). See Figure 3.1.
The T-bolts are only intended to secure the mounting
plate to the precombustor. The mounting plate must
be supported by the bolt assembly before installing
the burner.
2. Support the burner mounting bracket with a jack
screw (A) and nuts (B). Make sure the horizontal plate
is level. See Figure 3.2.
3. Briefly install the burner and flexible hoses into the
precombustor to make sure the supply piping will
permit easy burner installation.

Whenever the burner is not in use, plug the burner
block with a high temperature fiber wool rolled blanket.

this procedure to adjust the burner tip.

back.
