REFER TO NATIONAL AND ALL APPLICABLE LOCAL CODES FOR SPECIFIC INSTALLATION
REQUIREMENTS.
1.
The boiler should be mounted on a solid, level foundation.
2.
The boiler should be located with suitable clearances, refer to page 3 and Code requirements.
NOTE:
Allow minimum of 21 inches clearance in front of door for servicing of heating elements.
ALL PIPING SHOULD BE INSTALLED BY A QUALIFIED LICENSED PLUMBER IN ACCORDANCE
WITH NATIONAL AND LOCAL CODES.
1.
When water feed is other than pump type the water supply pressure must be 10 psig greater than boiler operating
pressure to assure water supply maintains proper water level in the boiler. Insufficient water levels can result in
improper boiler operation. (Keep feed water valves open at all times during normal operation.)
2.
If pump and boiler are plumbed within 30 feet (pipe length) a minimum of 2 check valves are required to avoid
damage to pump.
3.
Connect steam line with customer supplied outlet valve to boiler steam outlet.
4.
Provide for boiler drain connection, a daily blowdown is required. A "Blowdown Separator Tank" may be necessary,
check with local code.
5.
Safety valve shall be plumbed according to local code.
NOTE:
The safety valve shall not be plumbed with a line sized less than the outlet size of the safety valve.
ALL ELECTRICAL WIRING MUST BE PERFORMED BY A QUALIFIED ELECTRICIAN IN
ACCORDANCE WITH NATIONAL AND LOCAL ELECTRICAL CODES.
Assure that the power voltage and phase being supplied to the boiler matches the power voltage
and phase of the boiler. Connecting incorrect power supply can damage boiler components or cause
improper boiler operation. If the boiler power requirements do not match the power to be supplied to the boiler the
boiler must be returned to the factory for conversion. Boilers cannot be field converted.
ALL BOILERS ARE PRE-WIRED AND TESTED PRIOR TO SHIPMENT.
1.
Ground boiler according to National Electric Code requirements to avoid shock.
2.
Power wiring to boiler should be in accordance with National and Local Electrical Code requirements following
wiring diagram supplied. Use proper size wire. Wire size is specified adjacent to field wiring terminals. This label
states the wire size [AWG or MCM], minimum temperature rating (90 C) and conductor material (copper only).
Deviation from these requirements may result in improper or unsafe boiler operation.
3.
A disconnect switch employing circuit breakers or fuses should be installed between the main power source and the
boiler. This disconnect switch should be located near the boiler and clearly marked for easy access and identification
should the boiler need to be turned off due to an emergency.
4.
Boiler control circuit is 120 Volt*. Unless boiler has an optional step down transformer, a separate 120 Volt power
feed wiring is required to be connected to the control circuit terminal block. A 15 Amp circuit is required for all boil-
ers. If a 3/4 HP feed water motor and pump assembly is connected to the boiler, then a 20 Amp circuit is required.
