2 BG1600M Intermittent Pilot Ignition Control 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 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.
The spark electrode, flame sensor, and BG1600M
must share a common ground with the burner to
operate correctly. Thermoplastic insulated wire with
a minimum rate of 221˚F (105˚C) is recommended
for the ground wire. Ensure that the flame sensor
wire and the high voltage spark transformer wire are
separated from one another by a minimum distance
of 1/4 in. (6.35 mm) and are not wrapped around
any pipe, other wiring, or accessory.
Note: A shorting plug that jumpers pins 2 and 3 of
the damper connector is supplied with the control.
The shorting plug must be used if a vent damper is
not used. When a vent damper has been connected
and power turned on, an internal fuse in the control
will blow and the control will only operate with a vent
damper connected. Now you cannot disconnect the
vent damper plug and put back the shorting plug.
The ignition control will not work.
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 through Figure 6 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.
