FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE.
The 5059 Pilot Relight Control is a low voltage control that
generates ignition sparks. It is energized by the thermostat on a call for heat. Once flame is established, the
control senses the flame and stops sparking. If the pilot
flame is extinguished during a call for heat, the relight
control will begin sparking immediately upon sensing
absence of flame. The control delivers very low current
sparks (approximately 6,000 volts).

PRECAUTIONS
If in doubt whether you wiring is millivolt, line, or low
voltage, have it inspected by a qualified heating and air
conditioning contractor, electrician, or someone familiar
with basic electricity and wiring.
Do not exceed the specification ratings.
All wiring must conform to local and national electrical
codes and ordinances.
This control is a precision instrument, and should be
handled carefully. Rough handling or distorting components could cause the control to malfunction.
CAUTION
!
To prevent electrical shock and/or equipment
damage, disconnect electrical power to the system, at the main fuse or circuit box, until installation is complete.
Electrical Rating:
24 VAC (30 VAC max.)
60 Hz
0.030 Amps
CAUTION
!
Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper
and dangerous operation.
Following installation or replacement, follow
appliance manufacturer’s recommended installation/service instructions to insure proper operation.
This control is not intended for use in locations
where it may come in direct contact with water.
Suitable protection must be provided to shield
the control from exposure to water (dripping,
spraying, rain, etc.).
WARNING
!
Do not use on circuits exceeding specified voltage. Higher voltage will damage the control and
may cause shock or fire hazard.

NOTE
This control requires a connection to a dead metal
ground for proper control operation (mounting screws
provided accomplish this requirement). When used in a
grounded secondary circuit, T2 terminal must be connected to ground.
Some furnace manufacturers paint their furnaces. If so,
the paint must be scraped from both sides of a furnace
where the grounded mounting hole (identified by a chassis ground symbol on the 5059 pilot relight control) comes
in contact with the furnace wall (see figs. 1 and 2). To
ensure a positive equipment ground, make a final continuity check between the control grounding hole and the
furnace using an ohmmeter.
Grounding hole is identified
with chassis ground symbol

INSTALL THE 5059 CONTROL
Mount the control inside the furnace in a position so that
you have enough high voltage spark wire to reach the
electrode, but not to expose the control to excessive high
temperature conditions caused by the burner flame. The
5059 control can be mounted directly onto the furnace or
can be mounted on a standard 2” x 4” switch box.
The 5059 control has a 1⁄4” (interior) diamter terminal with
a ribbed spike. To connect a high voltage wire, cut the end
of the wire flush, to make a flat surface at the wire end.
Then push the wire end securely into the spike terminal to
ensure a proper connection (see fig. 3).
