INTRODUCTION TO "FD" SERIES
STEEL BOILER BURNER UNITS
Due to an excellent combination of boiler and burner,
the "FD" Series boiler-burner units are capable of
developing the optimum in combustion and thermal
efficiencies. The burner provides 12½% CO
2
for a
combustion efficiency in excess of 83% on #2 fuel oil.
Forced draft operation is accomplished by means of a
3450 RPM motor and blower wheel on the burner and a
factory sealed combustion chamber. The commonly
used refractory type combustion chamber is not
required.
Pressure is produced within the boiler by the "forced
draft" operation of the burner eliminating the need for a
chimney thus resulting in a substantial savings in
building costs. A vent to the outside of the building is
the only requirement. Boiler rooms can also be kept to
a minimum size since one boiler equipped with a
tankless heater can supply all of the heating
requirements for comfort heating and domestic hot
water.
For optimum performance and serviceability from these
units adhere to the following recommendations:
1) Clean boiler flueways (firetubes after removing
turbulator baffles) with a 3" OD flue brush, at least
once a year and preferably at the end of the heating
season, or as may be necessitated to remove all soot
and scale. See Page 10 for cleaning instructions.
2) Have burner and controls checked at least once a
year. See Pages 14, 15, 21 and 22 and burner
manual for burner adjustment specifications.
3) Retain your contractor or a competent service
agency to assure that the unit is properly adjusted
and maintained.
4) The interior of the venting must be inspected and
cleaned before the start of the heating season and
should be inspected periodically throughout the
heating season for any obstructions. A clean and
unobstructed vent is necessary to allow noxious
fumes that could cause injury or loss of life to vent
safely and will contribute toward maintaining the
boiler's efficiency.
For additional information consult the service department.
FLUE DAMPER:
The boiler is provided with a breaching damper which
should be secured in the open position for initial start up
of the burner. The adjustable damper in the flue collar
at the boiler outlet is provided so that if the installer or
serviceman desires, he can easily introduce a flow
restriction at the boiler outlet and thereby increase the
pressure in the firebox. Normally, it is best to leave the
damper wide open and to control air flow to the burner
entirely by adjustments at the burner inlet. Flue
restrictions such as a partially closed damper tend to
make starts rougher. Boiler tests were run at 12½%
CO
2
and 0.1 inches of water stack pressure to
demonstrate ample burner air capacity for good
performance up to this pressure. Boiler pressure drop
does not change measurably at different stack and
firebox pressures as long as the burner is adjusted to
maintain the same percent CO
2
.
MINIMUM INSTALLATION CLEARANCES TO
COMBUSTIBLE MATERIAL:
FRONT - 48 Inches ABOVE OR TOP - 18 Inches
SIDES - 18 Inches VENT CONNECTOR PIPE - 18 Inches
REAR - 18 Inches
NOTE:
1. Listed clearances comply with American National
Standard ANSI/NFPA 31, Installation of oil burning
equipment.
2. FD Series boilers can be installed in rooms with
clearances from combustible material as listed
above. Listed clearances can not be reduced for
alcove or closet installations.
3. For reduced clearances to combustible material,
protection must be provided as described in the
above ANSI/NFPA 31 standard.
4. Check dimensional data for boiler service
recommended clearances.
