16. ELECTRICAL REQUIREMENTS AND THERMOSTAT CONTROL
All electrical installations must meet local and the latest edition Electrical Code PART 1 CSA
C22.1 in Canada and ANSI/NFPA N0 70 in the U.S.A.. Single heater requires 24 Volt, 60 Hz
electrical transformer sized at 40VA. If multiple heaters are connected to a single transformer,
the proper transformer is 24 Volt, 60 Hz, sized at 40VA for the first heater, and 20VA each for
all subsequent additional heaters. For example, four heaters wired together (parallel), require
a transformer of 100 VA. It is recommended to install at most 2 heaters per zone for best
comfort control and economy of operation. PROPER WIRING POLARITY MUST BE MAIN-
TAINED, particularly when grouping the heaters in a zone.
Total wiring distances of up to 200' must use minimum 16 gauge electrical wire, and wiring
distances of over 200' must use minimum 14 gauge electrical wire. The heater must be elec-
trically grounded in accordance with the local
electrical code. Malfunction of the heating system will result if the voltage varies by more than
±10%.
The heater can be controlled by a line moisture proof thermostat “off-on” switch, or Remote
Control. Total load of all heaters must be considered in determining the required contact rat-
ing of the controlling thermostat or switch.
16.1 REMOTE CONTROL OPTION
Patio Heaters can be operated using Remote Control Option:
 JP-1234-RK Remote Receiver Kit (field installs in heater)
 JP-1234-HS Remote Handset
 Refer to the manual accompanying the Remote Receiver Kit for installation.
Start up - Heat Mode:
On a call for heat the Fenwal 35-60 control will reset, perform a self check routine, flash the
diagnostic LED for up to four seconds. The gas valve and spark are energized commencing
the trial for ignition period. When flame is detected during the trial for ignition, spark is shutoff
immediately and the gas valve remains energized. The thermostat and main burner flame are
constantly monitored to assure the system continues to operate properly. When the thermo-
stat is satisfied and the demand for heat ends, the gas valve is de-energized.
Flame Failure - Multi Trial Model:
Should the main burner fail to light, or the flame is not detected during the first trial for ignition
period, the gas valve is de-energized and the control goes through an interpurge delay before
another ignition attempt. The control will attempt two additional ignition trials before going into
lockout and the valve relay is de-energized.
Recovery from lockout requires a manual reset by either resetting the thermostat or removing
24 volts for a period of 5 seconds. If the thermostat is still calling for heat after one hour the
control will automatically reset and attempt to ignite the burner again.
