ALL ELECTRICAL WIRING MUST BE PERFORMED BY A QUAL-
IFIED 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 boilers. If a
3/4 HP feed water motor and pump assembly is connected to
the boiler, then a 20 Amp circuit is required.
5. If a separate control circuit is used, it should be connected to
the control circuit terminal block.
6. Remote mounted water feed systems (i.e. motor and pump)
should be connected to the junction box provided on the
outside of the boiler jacket.
7. With main power off, make sure all wiring terminations are
tight to avoid arcing, carbonizing or overheating of contacts.
Boilers are susceptible to lightning damage due
to water line connections. An industrial type lightning/surge
protector should be installed according to the manufacturer's
recommendation at the service entrance. Consult your
contractor or electrical dealer.
Substitution of components or modification of
wiring system voids the warranty and may lead to dangerous
operating conditions.
*220V for 380V and 415V boilers.

WARNING
REFER TO NATIONAL AND ALL APPLICA-
BLE LOCAL CODES FOR SPECIFIC INSTAL-
LATION REQUIREMENTS.
1. The boiler should be mounted on a solid,
level foundation.
2. The boiler should be located with suitable
clearances, refer to page 2 and 3 and Code
requirements.

ALL PIPING SHOULD BE INSTALLED BY A
QUALIFIED LICENSED PLUMBER IN ACCOR-
DANCE 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.
6. SSB Boilers have Stainless Steel all wetted
metal parts. SSB boilers shall be operated
using only deionized water, having a
maximum conductance of 1 microSiemen
per cm (1
µ
S/cm) [minimum specific resistivity
of 1 megohm per cm (1
ΜΩ
/cm)].
NOTE:
The safety valve shall not be plumbed
with a line sized less than the outlet size of
the safety valve.
