Explosion, Fire,
Scald, and Burn
Hazard
All heating appliances must have HIGH LIMIT protection to interrupt electrical power and shutdown the
burner if operating or safety controls fail and cause a runaway condition.
•Follow the appliance manufacturer’s wiring diagrams and note all required safety controls.
•Typical safety controls include high temperature or pressure limits, low water cutoffs, pressure relief valves and blocked flue sensing switches.
•Verify all limit and safety controls are installed and functioning correctly, as specified by the manufacturer, applicable safety standards, codes and all authorities having jurisdiction.
•Ensure that the appliance is free of oil and oil vapor before starting or resetting the burner.
Incorrect Wiring
Will Result in
Improper Control Operation
•GeniSys wiring label colors may not match the wire colors of the burner or other manufacturers’ controls.
•The GeniSys Control should be wired according to the appliance manufacturer’s instructions.
Mounting:
◦Mount the control on a 4” x 4” junction box on the burner, or inside the appliance cabinet. In replacement applications, mount the new control in the same location as the old control. In some replacement applications, it may be necessary to rotate the control on the 4” x 4” box for best fit.
◦Mounting orientation: any orientation is acceptable.
Wiring:
◦Make sure all appliance wiring complies with all local codes and ordinances.
◦Make connections to the control’s terminals as shown in Figures 2 through 9. Refer to the label on the underside of the control for wiring details.
Some Thermostats Are Polarity
Sensitive. Reversed polarity could cause erratic cycling of the burner control.
◦Connect the wire from the RH or R terminal on the thermostat to the TR terminal on the control (if applicable).
◦Connect the wire from the W terminal on the thermostat to the TW terminal on the control (if applicable).
