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 carbon steel coil by chemical

additives.

2. Purge air from boiler/water heater piping.

3. Check system for leaks. Repair as necessary.

SECTION VI

ELECTRICAL CONNECTIONS

Install electric wiring in accordance with National Electric Code or the

Canadian Electrical Code and local regulations. See the boiler’s

installation manual for wiring diagrams.

DANGER

Positively assure all electrical connections are unpowered before

attempting installation or service of electrical components or connections

of the water heater or building. Lock out all electrical boxes with padlock

once power is turned OFF.

WARNING

When installed, the water heater must be electrically grounded in

accordance with local codes or, in the absence of local codes, with the

National Electrical Code, ANSI/NFPA 70, and /or the CSA C22.1 Electric

Code.

Failure to properly wire electrical connections to the water heater may

result in serious physical harm.

Electrical power may be from more than one source. Make sure all

power is off before attempting any electrical work.
