2 BG1600M Intermittent Pilot Ignition Control with Rollout Switch Installation Instructions
Location Considerations
Choose a location that provides the shortest, direct
cable route to the spark electrode, pilot burner/igniter-
sensor assembly. Easy access to the terminals is
desired for wiring and servicing. The control may be
mounted in any position. Mount the control on a
grounded metal surface with #6 sheet metal or
machine screws through the mounting holes provided
in the enclosure.
The pilot burner/igniter-sensor must be securely
mounted to the main burner to ensure that the pilot
burner flame remains properly positioned with respect
to the main burner flame. The pilot burner must be
located such that the flame receives an ample supply
of air, free from the products of combustion. The flame
must not be exposed to draft conditions, the full force
of main burner ignition, or falling scale, which could
otherwise impede ignition of main burner flame.
Securely mount the pilot burner/igniter-sensor to the
main burner with metal screws at a distance
approximately 3/8 in (9.52 mm) above and 1/4 in. (6.35
mm) away from the center of the nearest main burner
port. Ensure that the main burner flames do not
impinge on any part of the pilot burner.
Wiring
!
WARNING: Risk of Explosion or Fire.
Locate all safety, limit, and operating controls in
series with the thermostat terminal (TH) on the
ignition control. Improper installation may cause gas
leaks, which can lead to an explosion or fire and
may result in severe personal injury or death.
Refer to Figure 1 for wiring diagrams. All wiring should
be in accordance with the National Electrical Code
(NEC) and all other local codes and regulations.
Check the voltage rating marked on the control and
make sure it is suited to the application. Use a Class 2
transformer capable of providing 24 VAC under
maximum load, including valves. A transformer having
excessive primary impedance due to poor coupling
affects the ignition potential.
The high-voltage spark transformer cable is noise
suppression (resistive) type rated for at least 15kV and
must not be in continuous contact with a metal
surface. Use standoff insulators. Ensure that the flame
sensor wire and high voltage spark transformer cable
are separated from one another by a minimum of
1/4 in. (6.35 mm) and are not wrapped around any
pipe, other wiring, or accessories.
!
WARNING: Risk of Electric Shock.
Before applying power to the control, connect the
high voltage cable to the spark transformer terminal
and spark electrode (pilot burner assembly). Verify
the ground wire is attached to the pilot burner and
the control ground terminal strip. Failure to follow
this procedure can cause electric shock and may
result in severe personal injury or death.

continuous retry
•
trial time for ignition is 85 seconds
•
prepurge period of none or 15 seconds
•
interpurge period of 15 seconds
•
main burner 400,000 Btu/hr maximum
•
pilot burners with flow rates of 1,500 Btu/hr or
less
•
must be used with redundant gas valves and
not subjected to temperatures below
-40˚F (-40˚C) or above 170˚F (77˚C)
