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

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.

is used. The user can monitor system functions when the boilers
are operational.
