INSTALLATION
2.13 Electrical Requirements
1. Heaters operate on 120 volts, 60 Hz, single phase.
The maximum amperage requirement (starting
current) is 4.8 amps per heater. The running
current is 1.1 amps.
2. Heater must be grounded in accordance with the
Canadian Electrical Code C22.1 (latest edition).
3. Wiring must not be exposed to direct radiant
output.
NOTE: 120V supply will incorporate a cord and plug, secured by a liquid-light connect when
"Outdoor Use" option is supplied.
24V control wiring will incorporate 5 ft. (1.5m) cord, secured by a liquid-light connect when
"Outdoor Use" option is supplied.
2.14 Thermostat Wiring:
One Two-Stage Thermostat and
One Two-Stage Series Heater
The Burner box contains a 24 volt transformer that
operates the control circuits. The thermostat is part of
this circuit. When installing a "snap action" CE-2S or
"mercury cell" 1F37-408 thermostat a three wire
connection is required.
- 24 volt terminal from the heater to the thermostat
terminal (R).
- 1st stage 24 volt from the thermostat (W1) to
heater number 1 low.
- 2nd stage 24 volt from the thermostat (W2) to
heater number 2 high.
See Figure 2.13.1.
When utilizing a thermostat that requires a constant
24 volt power supply such as the HL 201 or other
programmable thermostat, a fourth wire will be
required. Attach this wire to heater chassis. See
Figure 2.13.1.
