8 BGQ15HAA-1 Retrofit Spark Ignition System Installation Instructions
5. Remove the seal screw at the end of the regulator
stack.
6. Turn the gas on and place the thermostat at the
highest setting to cycle the ignition system.
7. Allow the system to stabilize. Adjust the screw in the
regulator stack to the desired reading on the
manometer. (Turn clockwise to increase the outlet
pressure and counterclockwise to reduce the outlet
pressure.)
8. Reinstall the seal screw, which incorporates the
proper size hole for venting to the atmosphere. (It
may be necessary to cycle the valve several times to
verify the desired outlet pressure.)
9. Turn off the gas supply and place the thermostat at
the lowest setting.
10. Remove the manometer and reinstall the pressure
tap plug.
11. Turn the gas on and check for leaks at the pressure
tap plug with a soap solution.
12. Set the thermostat to the desired setting before
leaving the site.

WARNING: Risk of Explosion or Fire. Follow
this or an equivalent checkout procedure after
installation. Before leaving the installation, verify that the
BGQ15HAA-1 functions properly and that the system
has no gas leaks. Gas leaks can lead to an explosion or
fire, and may result in severe personal injury or death.
!
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).
