8.
Use a 9/16” (or 14 mm) wrench
to remove the compression nut
connecting the burner gas tube to the
brass elbow. See Figure 9. Be sure to
use a ½” wrench to hold the elbow in
place so that the torque on the elbow
does not damage the back of the
main burner assembly. Remove screw
indicated in Figure 9.
9. Gently tilt heater forward to remove
burner panel. Be careful to not let
anything enter the holes in the panel.
10. Remove two screws that secure L-clip
and remove L-clip. (Only necessary
when replacing burner assembly). See
Figure 8.
11. Inspect the burner assembly. If any
foreign debris is on the surface,
attempt to manually remove. Do not
use any cleaning agents, vacuum
cleaner, or pressurized air to clean the
surface of the pad.
IMPORTANT:
If catalytic pad
deterioration is known or suspected,
take the heater out of service and
replace the burner assembly (see
Service Parts section on page 11).
12.
Inspect and clean pilot (mounted to
bracket) by using a vacuum or apply air
pressure through the holes in the pilot.
NOTE:
Burner should be removed as
described in Steps 1-10 above before
cleaning pilot due to the fragility of the
catalytic pad.
Burner and Pilot Flame
Visually inspect the burner and pilot
flame (by looking vertically down inside
the pilot guard) periodically during
use. The pilot flame should be blue
in color (not yellow) and will extend
beyond the thermocouple. The flame
will surround the thermocouple just
below the tip. Figure 6 shows a correct
pilot flame pattern and also shows
an incorrect pilot flame pattern. The
incorrect pilot flame pattern is not
touching thermocouple. This will cause
the thermocouple to cool. When the
thermocouple cools, the heater will
shut down.
If the pilot flame pattern is incorrect
or the pilot is yellow, cleaning may be
required.
It is also necessary to periodically clean
the interior casing of the heater behind
the burner for any foreign debris that
could cause a fire. Before performing
any cleaning action on the heater, the
burner must first be removed. Use the
following procedure to remove the
burner assembly.
1. Allow heater to thoroughly cool before
performing any maintenance.
2.
Turn OFF gas supply at remote cylinder
valve, and disconnect hose from
heater.
3. If wall mounted, remove from the wall
by lifting up and then away from the
wall.
4. Remove the access panel at the lower
back of the heater by removing the
(4) access panel screws. See Figure 7.
Remove the burner access panel by
removing the (2) burner access panel
screws.
5.
Remove the (2) two screws at the
bottom of the grill that secure the grill
bracket to the main enclosure of
the heater. See Figure 7.
6. Pull grill bracket away from the heater
by pivoting the grill out and upward.
Be sure that the hooks on the top
part of the grill do impact the fragile
catalytic pad causing it to puncture. If
the pad does become punctured, the
burner assembly must be replaced.
7.
Remove the (4) four screws connecting
the burner to the back of the heater.
See Figure 8.
