CONNECT STEAM BOILER SUPPLY PIPING

Figure 4 represents a typical steam boiler connection diagram. Refer to the boiler installation manual or contact the boiler manufacturer for an appropriate piping diagram. The use of a union, shut-off valves, and a drain valve is recommended for future service convenience. The use of an in-line “Y”-style strainer is required to prevent accumulation of sludge in the water heater’s coil.

Figure 4 – Typical Steam Boiler Connections (connections available below the water line)

NOTICE

Typical steam boiler without connections available below the water line is no recommended due to insufficient water temperature, especially during warmer months when the space heating system is not operational. Boiler water temperature at the bottom of a steam boiler can be 50°F lower than the boiler’s water temperature limit setting during such periods.

FILL BOILER SYSTEM

1.On new boiler installations, do not purge the boiler or space heating system through the water heater. During any boiler or space heating system flushing, cleaning, or purging, the water heater should be isolated to avoid possible attack on the carbon steel coil by chemical additives.

2.Purge air from boiler/water heater piping.

3.Check system for leaks. Repair as necessary.
