WARNING: Risk of Explosion or Fire. Verify
that there are no gas leaks by testing with appropriate
equipment. Never use a match or lighter to test for the
presence of gas. Failure to test properly can lead to an
explosion or fire and may result in severe personal injury
or death.
Make sure all components function properly by performing
the following test.
1. Before starting the appliance, perform a safety
inspection of piping, burners and venting. Check for
water leaks, etc. Check all wiring for proper
connections. Be sure the system is properly
grounded, including ground connection to the pilot
burner.
2. With the gas and thermostat off, turn on power to the
appliance.
3. Turn the thermostat to a high setting and verify that
the control goes through the operating sequence to a
shutoff condition.
Note: The burner does not light because the gas is
off.
4. Turn off the thermostat.
5. Turn on the gas and purge gas lines of all air.
6. Check for gas leaks on all pipe joints upstream of the
gas valve with a soap solution.
7. Turn the thermostat to the highest setting and verify
successful ignition and a normal run condition for at
least 5 minutes. If the appliance fails to run, see the
Troubleshooting section.
8. Check for gas leaks on all pipe joints downstream of
the gas valve with a soap solution.
9. Turn the thermostat down for at least 30 seconds
and then back up again. Verify successful ignition at
least five times.
10. Return the thermostat to a normal temperature
setting before leaving the installation.

WARNING:
The control module can not be serviced by user. If any
faults are detected, the control module must be
replaced. If control module has been opened or any
attempts to repair are done, the warranty is void.
Operation
Operating Mode Definitions
The following definitions describe the BG1600M operating
conditions.
• Prepurge: Initial time delay between thermostat
contact closure and activation of the spark circuit and
pilot valve.
• Trial for Ignition: Total time the pilot valve is
energized and spark/sense sequence is activated in
an attempt to light the pilot. The control attempts to
prove flame within the trial-for-ignition time.
• 100% Shutoff: If the control does not prove the
presence of pilot burner flame within the trial for
ignition, the spark circuit and pilot valve are
de-energized.
• Recycle: If 100% shutoff occurs, the control delays
for a specific recycle delay period before beginning
another trial for ignition (models with recycle only).
• Run: Main valve is energized and spark turns off after
pilot flame is proven. The main valve remains
energized until the thermostat is satisfied.
• Flameout: Loss of proven flame. Should a flameout
occur, the main valve de-energizes and spark recurs
within 2.0 seconds.
• Lockout: An internal or external fault has caused the
control to de-energize the spark circuit and valve
relays. The thermostat contacts must be opened for
30 seconds and then closed to begin another trial for
ignition.
• Inter-Purge: Period between trials for ignition when
both the gas valve and spark are de-activated to allow
unburned gas to escape before the next trial.
