BURNER WIRING SCHEMATIC/INTERCONNECTION DIAGRAM

If any of the original wire as supplied with the appliance must be replaced, it must be replaced with wiring material
having a temperature rating of at least 302°F (150°C) and shall have a minimum size of 16 AWG.

BURNER WIRING LADDER DIAGRAM

•

 

When the 120 VAC thermostat calls for
heat, power is applied to the factory
supplied power cord, or when the 24
VAC thermostat calls for heat, the
relay is energized applying 120 VAC to
the factory supplied power cord.

•

 

120 VAC is applied to the blower and
validation light PL-1 indicates power is
ON.

•

 

Air flow switch closes contacts after it
senses an increase in air pressure due
to fan reaching operational speed.

•

 

Validation light PL-2 indicates
combustion air supply and exhaust
venting back pressure is normal.

•

 

Ignition Detection Control (IDC) is
turned on and begins a 15-second pre-
purge time period.

•

 

The pre-purge period is followed by a
15-second trial for ignition during
which a spark is developed at the
igniter and the gas valve is opened to
the first step of its two step operation.

•

 

Burner ignites and 5 seconds later the
gas valve steps up to its operating
position.  DC electrical current flows
from sensing electrode through flame
to ground.

•

 

IDC senses flame presence, turns
OFF spark, gas continues flowing
through valve.

•

 

Validation light PL-3 indicates normal
burner operation.

•

 

During first trial-for-ignition period or
upon any flame outage at sensing
electrode, the IDC responds and
begins sparking within 0.8 seconds.  A
15-second trial-for-ignition period
begins to re-light the burner.  If flame
is re-established, normal operation
resumes.  If the burner does not light
after first try, the inter-purge sequence
is completed between trials to re-light
the burner.  If the burner fails to light
(10DX-117) or after third trial (35-725),
IDC will de-energize the valve and go
into lockout mode.

•

 

For lockout recovery, reset thermostat
below ambient temperature or
disconnect electrical power supply for
5 seconds. If the flame does fail during
ignition or normal operation, it is
detected by the flame sensor rod, and
the IDC then closes the gas valve
locking out the system until the
thermostat is cycled to the OFF
position.

•

 

When the thermostat is satisfied, the
whole system is de-energized until
another call for heat.

•

 

When installing or servicing this
heater, wait at least 5 minutes
between attempts for ignition.

If any of the original wire as supplied with the appliance must be replaced, it must be replaced with wiring material
having a temperature rating of at least 302°F (150°C) and shall have a minimum size of 16 AWG.
