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.
IMPORTANT: Only qualified personnel should
install or service BASO Gas Products®. If any faults are
detected, see Troubleshooting Table 2. If control
module has been opened or any attempts to repair are
done, the warranty is void.

Sequence of Operation
The heating cycle starts when a call for heat from the
thermostat supplies 24VAC to the 24V/TH terminal. After
a 1 second maximum diagnostic period, the control enters
pre-purge mode, after pre-purge time, the spark starts
and the gas valve opens, starting with the trial for ignition
period. If no pre-purge, trial for ignition mode begins
immediately (see Table 1 for red LED normal operation).
During the trial for ignition period, the control sparks while
rapidly flashing red LED. It then turns off the spark and
red LED while checking pilot flame sense. This cycle will
repeat until pilot flame is detected or trial time is over.
When pilot flame is detected, the spark stops, the gas
valve remains open and the red LED stays on
continuously. The control will remain in this state until the
pilot flame is lost or the call for heat ends. Model with no
inter-purge, if the pilot flame is lost, the gas valve
remains open and a new trial for ignition will start. Model
with inter-purge, if flame is lost within 5 seconds of an
established flame, the gas valve remains open; the control
initiates sparking, and begins a trial for ignition period
immediately. If flame is lost after 5 seconds of an
established flame, the gas valve will close, and the control
initiates the inter-purge time delay before beginning
another trial for ignition period. Model with no retry and
one trial, if pilot flame is not detected during the trial for
ignition period, the gas valve will close. Lockout will occur
and a red LED will flash indicating an error (see Table 2
for proper diagnostics of the error). Remove power to end
lockout. Model with retry and three trials, if flame is not
sensed by the end of the trial for ignition time period, the
gas valve will close and the control module will initiate an
inter-purge time delay, followed by another trial for ignition
period (this occurs up to three trials). After the third trial,
the control will initiate a 5 minute retry period. If flame is
not sensed, the ignition sequence will repeat, until flame is
sensed. If flame still is not sensed, remove power to reset
the ignition.
