Installation / Operation Instruction Manual

Water Connections continued-

NOTICE

Typical steam boiler without connections available below the

water line is not 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 coil by chemical additives.

2. Purge air from boiler/water heater piping.

3. Check system for leaks. Repair as necessary.
