Result in Improper
GeniSys wiring label colors may not match the

ers’ controls.
The GeniSys Control should be wired accord-
ing to the appliance manufacturer’s instruc-
tions.
Control Operation
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 ue
sensing switches.
Verify all limit and safety controls are installed
and functioning correctly, as specied by the
manufacturer, applicable safety standards,
codes and all authorities having jurisdiction.
Ensure that the appliance is free of oil and oil

All heating appliances must have HIGH
LIMIT protection to interrupt electrical
power and shutdown the burner if
Explosion, Fire, Scald,
and Burn Hazard
operating or safety controls fail and cause a
runaway condition.
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 t.
Mounting orientation: any orientation is ac-
ceptable.
