BENT STEEL TUBE
CONSTRUCTION
Introducing a new line of Hot Water
Boilers incorporating a built-in
finned steel tube bundle in addition
to the standard boiler tubes. These
heavy duty finned tubes are placed
above the standard Parker tubes,
and they significantly increase the
amount of heat absorbed from the
flue gases, thus increasing boiler
efficiency.
With the additional heating
surface, the already long Parker Hot
Water Boiler life is extended even
further. The efficiency with Atmospheric Burner firing is 82%-85%,
and with our Premix Metal Fiber
Low NOx Burner the efficiency is
84%-86%. Test units have been
in the field under harsh conditions
operating successfully for 11 years.

2. Simplicity
The design of the boiler and control
system is such that the boiler can
be easily operated, maintained and
repaired by regular personnel. On
atmospheric units simplicity is a
decided advantage as there are no
complicated controls, blowers, or
burner air adjustments.
"Never a Compromise for Quality or Safety"
3. Codes
All Parker Direct Fired Boilers are
manufactured in accordance with
the ASME Power & Heating Boiler
Codes and registered with the
National Board of Boiler and Pressure Vessel Inspectors.
Natural gas and LPG fired
models are ETL Listed “Industrial
and Commercial Gas Fired Packaged Boilers” certified to UL795, for
indoor or outdoor service. Canadian
models are C-ETL Listed.

4. Heavy Welded Flexible
Tube Construction
The Parker steel tube bundle is
1-5/16” O.D. steel, over 1/8" heavy
thickness, and the finned tubes
are 1” O.D. (.11”), heavy thickness steel. The welded bent tube
design permits free expansion and
contraction of each tube indepen-

dently when subject to thermal
shocking. Our design eliminates
strain on the metal, warping and
leaking, typical of rigid straight
tube designs. This construction
utilizes heavy material with flexibility to provide extreme safety
and long life.
5. Heavy Insulated Cabinet
The cabinet is durably constructed
with two thicknesses of heavy
steel, insulated on all sides with
high temperature thermal fiber
insulation to effectively reduce
heat losses to a minimum.
THE PARKER DESIGN
A time proven product backed by
one of the largest and most successful manufacturers of packaged boilers whose name is synonymous with quality and safety.
Every boiler is thoroughly factory
fire tested and is required to meet
the highest standards in all phases
of mechanical and operating efficiency before shipment.
