NOTES:-
Power On light is permanently illuminated when 120V / 60 Hz AC external supply is connected to
burner.
Additional wiring is required to install an optional extra thermostat and / or time clock.
If no thermostat is required then a jumper is fitted between terminals R and W1. In this configuration
the burner will continuously fire until the 120V power supply is disconnected.
Wire specification:- 18 AWG (1.0mm²), Tri-rated, 105°C
