Boiler Startup Procedure
NOTE:
Before operation it may be necessary to check the 2000 and 3000 level parameters on each
control board. See Section 9.16 and Appendix B for further information.
1.
Open the manual gas shut off valve (Figure 7-1),
2.
Turn the unit power switch to ON (item “T” in Figure 8-1).

The boiler will fire only when there is a call for heat and the heating temperature setting is
higher than the actual supply temperature. Hold buttons
or
to select the desired
heating temperature. If the external temperature sensor is connected (see Section 5.2.2),
check that the calculated temperature (See User Menu, Section 9.15, parameter 1012 or
parameter 1107) is higher than the actual boiler temperature and that the outdoor
temperature (See User Menu, Section 9.15, parame
ter 1004) is lower than “warm weather
shut down temperature” (See Section 9.16, parameter 2020 in Installer Menu).

If the boiler is connected to an indirect water heater, press buttons
and
to select
the desired domestic hot water temperature.
