Replace Burner
After all maintenance/repair is completed,
replacing the burner is generally a reversal of the
removal process with the following additional
guidelines:
1. When the assembly has been pushed back
into the ironing cylinder, have a worker
help guide the tail pipe into place.
2. With two people at the left endframe push -
ing down slightly on the burner assembly,
the third person reaches into the ironing
cylinder helps guide the tail pipe through
the opening in the right endframe.
3. Once the tail pipe is seated in the opening,
slide it the rest of the way into position.
4. Make sure it is properly positioned in its
holding bracket.
5. Reinstall the burner support removed in
Step 13 of Remove Burner on page 4-18 .
6. Make sure the burner is properly oriented
and physically secured.
7. Securely rejoin the gas line union for the
burner (Figure 4-12, B). Use pipe thread
compound to assure a leakproof connec-
tion.
8. Reconnect the pilot gas line (Figure 4-12,
A). Use pipe thread compound or Teflon
tape to assure a leakproof connection.
9. Reconnect the flame sensor and ignition
electrode wires as noted in 6 of Remove
Burner on page 4-18 .
10. Reposition and secure the protective
backplate. This piece should be handled
by two maintenance personnel.
11. Make sure the internal valve is in the fully
ON position.
12. Close and secure both endframe doors.
