C. Operating Instructions
Before operating the unit, it is important to remove the cover
and verify that the gas line and water lines are connected to
boiler and fully purged. If you smell gas, STOP; Follow the safety
instructions listed in the first part of this section. If you do not
smell gas, follow the next steps.
1. Turn down the thermostats before applying power to the
boiler. If 0–10 volt or other inputs are used, make sure that they
are set so there is no call for heat while programming.
2. Turn on the power to the boiler or boilers if a cascade system
used.
3. Next, check the boiler settings. Adjustment and factory
defaults are outlined within this section. If a cascade system is
used, it is important that all the boilers have the same boiler
settings.
4. Next, check the system settings. Adjustments and factory
defaults are outlined within this section. If a cascade system is
used, it is important that the Master Boiler is programmed with
the correct system settings.
5. Create a demand on the boiler or boilers if a cascade system
is used. The user can monitor system functions when the boilers
are operational.
6. If the boilers fail to start, refer to the troubleshooting section
in the back of this manual.
