SECTION 1.
General Information

Newport boilers have been designed and
con struct ed ac cord ing to ASME codes using heavy
gauge steel tubes and boiler plate.

The reliable heat exchanger incorporates special
flue baffles to assure quiet and efficient operation and
a pur pose designed ceraform combustion cham ber
min i miz es base loss and also provides a tight enclosure
with the heat exchanger.

The domestic hot water coil is located at the top
of the boiler in the hottest zone for an ample supply
of hot wa ter. A unique feature of its attachment is the
raised coil flange which allows the use of clamping
bolts rather than studs, thereby elim i nat ing water leaks
caused by broken studs.

The complete unit comes pre-assembled for easy
in stal la tion and is encased by a fully insulated baked
enamel jacket.

As delivered, the boiler's burner is equipped with
a nozzle for 0.85 (NP 85-110) or 1.25 (NP 125-150)
gallons of #2 heating oil. Provided with the boiler are
two (2) additional nozzles that permit higher firing
rates. See Table 1 below.

Installation of either of the two (2) additional
nozzles, in place of the factory-installed nozzle, will
provide the corresponding performance indicated in
the chart labeled “Performance”, on page 7, for the
alternate nozzle installed. Boilers equipped with Carlin
burners also require a change of the Head Positioning
Bar (also provided).

1.3 Boiler Location

The boiler should be positioned as near to the
chim ney as possible and have a minimum smoke pipe
connector length of 18"(457mm).

CAUTION

Newport boilers must not be directly connected
to a heating system using oxygen permeable
tubing (see warranty). Use a water to water
heat exchanger between boiler and system to
prevent corrosion.

1.4 Boiler Clearances (to combustibles)

Top - 6" (152mm) Front - 24" (610mm)

Rear - 6" (152mm) Sides - 6" (152mm)

1.5 Floor

The boiler must be mounted on a noncombustible
ma son ry or cement floor with no com bus ti bles
un der neath.

1.6 Combustion and Ventilation Air

To insure an adequate supply of fresh air for
com bus tion and ventilation an inlet and outlet opening
should be pro vid ed at floor and ceiling level. Each
opening must have a minimum of one square inch
(16.5 sq. cm) of free area for every 1,000 BTU/h
(293kW) of input or 140 square inches (903 sq. cm)
per one gallon (3.785L) of oil burned per hour. The
openings must not be in a position liable to blockage.

1.1 Boiler Installation

For recommended installation practice reference
should be made to the National Fire Protection
Stan dard for Oil Burning Equipment (NFPA 31 ­Latest Edition).

1.2 Freight Claims

Inspection should be made of boiler and its
com po nents for damage upon arrival. Any claims for
damage should immediately be filed against the carrier
by the consignee.

1.7 Chimney and Draft Requirements

To assure the safe and proper operation of the
oil burner the boiler must be connected to a chimney
having suf fi cient draft at all times to evacuate the
flue gases to at mo sphere. A draft regulator must be
installed in the smoke-pipe as near to the flue as
possible and adjusted to achieve an overfire draft of

0.01 ins. W.C.

1.8 Jacket (normally fitted)

If not fitted, assemble panels in accordance with

in struc tions in Figure 4.

1.9 Oil Burner (normally fitted)

If not fitted, insert burner tube into boiler so
that it is ap prox i mate ly ¼" (6mm) from inside wall of
ceraform chamber, then clamp mounting flange and
bolt up to front-plate (see Figure 3).

The burner should be wired and connected to
the oil line in accordance with the manufacturer’s
instructions.

1.10 Installation of Alternate Nozzles for

Higher Output

This operation shall only be carried out by a
trained and licensed Service Technician in accordance
with the burner manufacturer’s instructions included in
the literature package provided with this boiler.

1.11 Boiler Controls (normally fitted)

If controls are supplied separately, fit them to the
boiler in the positions shown in Figure 3, with jacket
in place.

Circulator - 1¼" return tapping at front of boiler.

Tridicator - temp/press. gauge.

Relief Valve - Provide ¾" tee and auto vent as
shown on front page for air elimination.

Aquastat Relay - L8124A or L7224A - ¾"
tapping in coil plate.

Fit a drain valve (not supplied) in a tee at
hy dron ic return connection and check all connections
are made wa ter tight.

1.12 Oil

USE ONLY No. 2 HEATING OIL. Do not use
gasoline, crankcase draining or any oil con tain ing
gasoline.

1.13 Oil Storage and Pipe Layout

Storage Tank: Consult local fire and building
codes for acceptable fuel storage methods in your area.

Fuel Line: A single pipe system of not less
than 3/8" OD copper tubing is recommended when
fuel storage level is not below the fuel unit. A two
pipe system of not less than 3/8" OD copper tubing is
recommended when lowest fuel level is below but not
more than 8 feet below fuel unit.

Important: Refer to burner (pump) instructions
for detailed fuel line and pump usage information. All
installations must conform to local and national codes.

See Figures 5A and 5B.

layout.

1.14 Electrical Wiring

All wiring must comply with the National
Electrical Code, NFPA 70, local codes and ordinances
regarding wire size, type of insulation and enclosures
etc. (see Figure 6).

1.15 Operation (Honeywell L8124A or

L7224A aquastat relay)

A call for heat from the room thermostat causes
the re lay to “make “ the burner circuit and also feed
the cir cu la tor provided the boiler water tem per a ture is
above the low limit setting (usually 190°F [88°C] to
210°F [99°C]). The burner and cir cu la tor then continue
to run until the room thermostat is satisfied.

A high limit switch shuts off burner in the event
of water temperature exceeding the high limit setting,
usually 20°F (-7°C) to 30°F (-1°C) above the low limit
setting.

The low limit switch and circulator maintain
boiler water temperature for domestic hot water
ser vic es and pre vent circulation of heating system
water if domestic water is not hot enough.

1.16 Domestic Water Piping

1. Connect anti scald tempering valve (12) “HOT”

port to hot water outlet from unit. This valve

should be mounted 3" (76mm) to 6" (152mm)

below the outlet and set for 120° F mixed

delivery temperature or as local codes dictate

(see Figure 1).

2. Connect gate or shutoff valve (13) to anti scald

tempering valve (12) “MIX” port, and another to

the cold water inlet.

3. Connect pressure relief valve (11) (if required

by codes), maximum 150 PSI as close to the unit

as possible. No other valves or restrictions may

be installed between the DHW coil and the

relief valve.

(DO NOT USE A TEM PER A TURE/PRES SURE
RELIEF VALVE AS THIS IS NOT A STOR AGE
HOT WATER HEATER).
