Figure 18 shows a correct pilot

flame pattern. Figure 19 shows an

incorrect  pilot  flame  pattern. The

incorrect  pilot  flame  is  not  touching

the thermocouple.This will cause  the

thermocouple  to  cool.  When  the

thermocouple  cools,  the  heater

will shut down. If   pilot  flame  pattern
is incorrect, as shown  in  Figure  19.

1.

Remove screws from the fan

 bracket panel , pull the fan bracket
 panel  out to remove. Then disconne-
ct two wires  free to fan.
2.

Mark or tag each wire removed

 for its  exact reconnection. Remove
the four screws from the fan .when
 installing , reverse the steps above.
(See  Figure 23 and Figure 26)

2. Remove two screws and hex nuts,
 take out the control module.  When in-

The primary air inlet holes allow the
proper amount of air to mix with the
gas. This provides a clean burning
flame. Keep these holes clear of  dust,
dirt, lint, and pet hair. Clean these air
inlet holes prior to each heating season.
Blocked air holes will create soot. We
recommend that you clean the unit
every three months during operation
and have heater inspected yearly by a
qualified  service  person.
