D. START-UP INSTRUCTIONS
Before operating the boiler, it is important to remove the cover and verify that the gas line and water lines are connected and that there
are no leaks. If you smell gas, STOP. Follow the safety instructions listed at the beginning 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 is used.
NOTE: To avoid any start-up issues, purge the system of air and review and appropriately set the following settings and parameters at
first power up.
