ELECTRICAL SUPPLY AND THERMOSTATIC CONTROL (1 OF 2)
ELECTRICAL SUPPLY 120 VAC THERMOSTATIC CONTROL
24 VAC THERMOSTAT AND TRANSFORMER
•
Voltage: 120VAC- 1 phase- 60 Hz.
•
Maximum Amps: 3.0 (1.33 actual full load amps).
•
Flame safety: Electronic.
•
Ignition: Direct Spark.
•
Wiring must conform to the latest edition of the
National Electric Code (ANSI/NFPA 70) or local
code legally authorized.
•
Electrical power takeoff must be connected to a
separately fused circuit with a disconnect, and
must be properly polarized and grounded to the
heaters power cord.
•
Do not run wiring over the heaters or in direct
view of radiant heat.
•
If any of the wiring supplied must be replaced
use type 16 AWG (1.0mm
2
), or equivalent with
2/64” (.08 cm) insulation and a minimum
insulation temperature of 302°F (150°C).
CAUTION – 24VAC THERMOSTAT
DO NOT try to connect more than three burners to a
24 VAC thermostat. The transformer relay is rated to
operate only three heaters safely. Failure to do so
may cause serious bodily harm or property damage.
SEQUENCE OF OPERATION
BURNER WIRING SCHEMATIC/INTERCONNECTION DIAGRAM
•
Thermostat calls for heat.
•
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 pre-purge time period.
•
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 five (5) seconds.
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.
