ERROR CODE TABLE

Check gas, water and electrical supplies are available at the
1
boiler
Electrical supply = 120V ~60 HZ
2
The preferred minimum gas pressure is 3.5" wc for Natural
3
gas and 10" for LPG
Perform electrical system checks, i.e. Ground Continuity,
4 Resistance to Ground, Short Circuit and Polarity with a
suitable meter.
NOTE: These checks must be repeated after any servicing
or fault finding.
Ensure all external controls are calling for heat and check
all external and internal fuses. Before any servicing or
5
replacement of parts, ensure the gas and electrical supplies
are isolated.

E
a) If within a time between 15...30 seconds of the burner
lighting the boiler temperature has not changed by 2°F.
b) If within 10 minutes of the burner lighting the boiler
temperature twice exceeds the selected temperature by
80°F.
In these instances poor primary circulation is indicated.
E
normal burner operation.
E
interrupted, ignition has failed or flame has not been
detected.
