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).
1.1 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.
1.3 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.
1.7 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.
