7.2 ADDITIONAL FAULTS WITHOUT SPECIFIC FAULT MESSAGES

Refer to Table 7-2 to troubleshoot faults which may occur without a specific fault message being displayed.

TABLE 7-2. WATER HEATER TROUBLESHOOTING WITH NO FAULT MESSAGE DISPLAYED

OBSERVED INCIDENT

PROBABLE CAUSES

CORRECTIVE ACTION

Fluctuating Gas Pressure

Gas pressure going into unit is

fluctuating.

Damping Orifice not installed.

Stabilize gas pressure going into unit. If necessary,

troubleshoot Building Supply Regulator.

Check to ensure that the Damping Orifice is installed in the

SSOV Actuator shown in Figure 7-3. (For DBB Gas Trains,

the Damping Orifice is installed in the downstream SSOV

Actuator).

Air/Fuel Valve “hunting” at

the 80% Valve Position

IGST and Power Supply Boards

in Control Box are outdated.

Check to ensure that the IGST and Power Supply Boards

are Rev. E or higher.
