Remediation Steps
Remove power and shut-off gas supply as
necessary.
1.) Remove valve front electrical
enclosure and verify the Pressure Module
terminating connector is fully inserted
in the socket labeled 'PRESSURE' in the
electrical enclosure.
2.) Check for a nearby source of strong
electro-magnetic interference. Reset valve
and burner management system when
corrected.
3.) Remove Pressure Module from valve
body.
4.) Inspect the O-ring provided on the
Pressure Module to ensure that it is clean
and fully seated in its oval groove.
5.) Verify the Pressure Module is correctly
seated on the valve body locating posts,
is flush against the valve casting and the
O-ring is compressed.
6.) Verify the correct mounting location
and pressure port are being used for the
valve model - refer to documents 32-
00017 and 32-00029.
7.) Recommission Low and High gas

pressure settings as necessary.

1.) Verify the Pressure Module rating is

correct for the application.

2.) If the Pressure Module rating is correct,

reset valve and burner management

system, observing burner operation for
proper pressures.

3.) Adjust appliance regulator as

necessary.
4.) Recommission Low and High gas
pressure settings as necessary.
5.) Test Low and High gas pressure trip
points as necessary.
6.) If inlet pressure is higher than Pressure
Module rating, remove power and shut off
gas supply and replace Pressure Module
with higher rated version.
Replace valve main electronics board.
