120v GeniSys Control Installation and Operation Manual
Incorrect Wiring
Will Result in
Improper Control Operation
•
The control wiring label colors may not
match the wire colors of the burner or
other manufacturers’ controls.
•
The control should be wired according
to the appliance manufacturer’s
instructions.
Fire or Explosion
Hazard
Can cause severe injury, death, or
property damage.
•
The control can malfunction if it gets
wet, leading to accumulation of oil or
explosive oil vapors.
•
Never install where water can flood,
drip or condense on the control.
•
Never use a control that has been wet
- replace it.
Electrical Shock
Hazard
Electrical shock can cause severe
personal injury or death.
•
Disconnect ALL electrical power to
the appliance/burner circuit before
installing or servicing this control.
•
Provide ground wiring to the
appliance, burner and metal control
mounting box.
•
Perform all wiring in compliance with
the National Electrical Code ANSI/
NFPA 70 (Canada CSA C22.1).
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 but not
limited to 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.
Some Thermo-
stats Are Polarity
Sensitive. Reversed
polarity could cause erratic cycling of
the burner control.
◦
Connect the red wire from the R
H
or R
terminal on the thermostat to the T
r
terminal on the control.
◦
Connect the white wire from the W terminal
on the thermostat to the T
w
terminal on the
control.
◦
Some thermostats may require connection
to the T
C
terminal on the control for proper
operation (see Appendix C).
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, except upside down or with
the terminal block (front) facing up.
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.
