1c).
1. Disconnect the Staged Ignition Assembly
solenoid from the Gas injector Tube of the
Igniter-Injector (Figure 8-1a through Figure 8-
1c) and inspect Gas Injector to ensure it is not
clogged or damaged.
2. Defective Staged Ignition
Solenoid (Figure 8-1a through
Figure 8-1c).
2. Close the Manual Shutoff Valve. Attempt to
start the unit and listen for a “clicking” sound
that the Staged Ignition Solenoid makes
during Ignition Trial. If “clicking” sound is not
heard after 2 or 3 attempts, replace the
Staged Ignition Solenoid.
1. Gas pressure going into unit is
fluctuating.
1. Stabilize gas pressure going into unit. If
necessary, troubleshoot Building Supply

2. Damping Orifice not installed.
2. Check if the gas train is supposed to have a
Damping Orifice, and if so, ensure that it is
installed in the SSOV Actuator, as shown in
Figure 10-1, below. For DBB Gas Trains, the
Damping Orifice is installed in the
downstream SSOV Actuator).
