ELECTRICAL SUPPLY AND THERMOSTATIC CONTROL
ELECTRICAL SUPPLY
120 VAC THERMOSTATIC CONTROL
HEATERS IN SERIES WITH A 120 VAC THERMOSTAT
•
Voltage: 120 VAC – 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.
•
Have a qualified electrician check that the
electrical supply circuit and wall receptacle are
properly grounded and that the electrical
supply polarity is correct. The heater control is
polarity sensitive and will not operate properly
if the electrical supply is not wired correctly.
•
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” (.08cm) insulation and a minimum
insulation temperature of 302°F (150°C).
GENERAL INSTALLATION NOTES
24 VAC THERMOSTAT AND TRANSFORMER (MAX. 3 HEATERS)
•
Locate the thermostat as specified in the
heating plan.
•
If it is not in the heating plan, follow the
instructions provided with the thermostat.
•
If instructions are not provided with the
thermostat, locate it four to five feet above the
floor where it will not be directly affected by the
heat from the heater, outside drafts, or the
sun.
•
A location that best represents the average
temperature of the room is the most desirable.
•
If two heaters are installed on a common
exhaust vent they must be controlled by the
same thermostat.
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.

* When installing these heaters to any thermostat,
the installer should allow for 3 amps per heater as
the blower tends to use more electricity than its
rating during its start-up period. This is why all of
the 24 VAC thermostats must be connected to a
120 VAC transformer relay, which will safely
support only three heaters.
Note: The brown wire is not used, but may be electrically hot. Protect
personnel and the circuit by screwing on a wire nut.
