Chapter 10: Boilers, Water Heaters and Pressure Vessels

The water feed system to your boiler has a pressure reducer valve. That reduces the pressure delivered from the city (or even a well system) so that the loop is not over-pressurized. The setting on most pressure reducer valves is 12 PSI. That is likely the pressure on your boiler system.

OPERATOR'S MANUAL

If boiler have single pump, open exist pumps in / out valves. d) While filling water into boiler, switch off alarm and burner starter switch on the electricity board. Consequently burner and alarm siren sound system will be shut down and they will be not functional. After completing water filling process, all these switches must be opened.
