10 BG1100M Direct Spark Ignition Control Installation Instructions
Maintenance Requirements in Severe
Environments
Regular preventive maintenance is important in any
application, but especially so in commercial cooking,
agricultural, and industrial applications because:
•
In many such applications, particularly
commercial cooking, the equipment operates
100,000 to 200,000 cycles per year. Such heavy
cycling can wear out the gas control in one to
two years. A normal forced air furnace, for which
the controls were originally intended, typically
operates less than 20,000 cycles per year.
•
Exposure to water, dirt, chemicals, and heat can
damage the ignition control module or the gas
control and shut down the control system. A
NEMA 4 enclosure can reduce exposure to
environmental contaminants.
!
WARNING: Risk of Explosion or Fire. Do
not attempt to take the ignition control module apart
or to clean it. Improper reassembly and cleaning
may cause unreliable operation, which can lead to
an explosion or fire, and may result in severe injury,
property damage or death.
Maintenance frequency must be determined
individually for each application. Some considerations
are:
•
Cycling Frequency – Appliances that may cycle
more than 20,000 times annually should be
checked monthly.
•
Direct Spark Use – Appliances that are used
seasonally should be checked before shutdown
and again before the next use.
•
Consequence of Unexpected Shutdown –
Where the cost of an unexpected shutdown
would be high, the system should be checked
more often.
•
Dust, Wet, or Corrosive Environment – Since
these environments can cause the controls to
deteriorate more rapidly, the system should be
checked more often.
Repairs and Replacement
!
CAUTION: Risk of Electric Shock.
Disconnect power supply before making electrical
connections to avoid electric shock.
!
WARNING: Risk of Explosion or Fire.
Shut off the gas supply at the main manual shutoff
valve before installing or servicing the control.
Failure to shut off the gas supply can result in the
release of gas during installation or servicing, which
can lead to an explosion or fire, and may result in
severe injury or death.
!
WARNING: Risk of Explosion, Fire, or
Electric Shock. Label all wires before they are
disconnected when replacing or servicing the
BG1100M. Wiring errors can cause improper or
dangerous operation and may result in an explosion,
fire, or electric shock leading to severe personal
injury or death.
Field repairs must not be made to the BG1100M
control. Any attempt to repair this assembly voids the
manufacturer’s warranty. For a replacement control,
contact the original equipment manufacturer or the
nearest BASO Gas Products distributor.
All other accessories, such as flame sensors,
electrode assembles, pilot assemblies, and leads can
be obtained through the original equipment
manufacturer or a BASO Gas Products distributor.
