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 E Series operating
conditions.
• Waiting Time (Prepurge): The initial delay between
the start signal and the safety time to allow ventilation
of the combustion chamber and flue passages to
displace any unburned gas and/or products of
combustion.
• Safety Time (Trial for Ignition): The time between
energizing the pilot gas valve and de-energizing the
pilot gas valve if the flame signal is not detected.
• 100% Shutoff: Pilot gas did not ignite within the
safety time (trial-for ignition time) or the amount of
trials. The control de-energizes the spark circuit and
gas valve, and enters into lockout.
• Retrial: Failing an ignition attempt, the control enters
the inter-waiting time (retry) and then starts another
safety time (models with optional retrials).
• Running Position (Run): The main valve and pilot
valve remain energized and the spark is de-energized.
The appliance is in normal operation under the
supervision of the ignition control and its flame
detector device.
• Flame Loss Response (Inter-Purge): The loss of
proven flame. The main and pilot valves are turned off
(de-energized) and the control waits the recycle
(Inter-Purge) time before another spark sequence is
started. For controls without recycle (Inter-Purge) time
the main valve is turned off (de-energized) and pilot is
turned on (energized) and a spark sequence recurs
within 2.0 seconds.
• Volatile Lockout (Lockout): The safety shutdown of
the system where a startup sequence can only begin
after the thermostat contacts or main power is cycled
(off, then on) to reset lockout.
• Non-Volatile Lockout (Lockout): The safety
shutdown of the system where a startup sequence
can only begin after the operation of the external reset
switch to reset lockout.
• Recycle (Inter-Purge): If shutoff occurs, the control
delays for a specific recycle delay period before
beginning another trial for ignition (models with
recycle only).
• Inter-Waiting Time (Retry): Period between trials for
ignition when both the gas valve and spark is
deactivated to allow unburned gas to escape before
the next trial. Inter-Waiting (Retry) occurs between
unsuccessful trials on a multi-trial control.
• Alarm Output: The alarm output uses the normally
closed contact on the safety relay. It will turn on if
flame fails to light in the safety time or a fault is
detected in the control. The output will also be on for a
half second on power up until the safety relay turns
on.
