THE PARKER DESIGN
The Parker water tube design
offers an extremely efficient, reliable steam boiler built for the long
term and ease of maintenance.
The Parker design offers many
advantages. Compare ours to the
competition.
ADVANTAGES
1. Safety
Our ASME tube bundle is extremely flexible and offers a long life
with a 25 year warranty against
thermal shock. No Parker Boiler
has ever been known to experience an internal explosion.

Horizontal Drum Sectional Water Tube
7-25 HP Gas Fired
103L Steam Boilers 7-25 HP
Low NOx Premix

Steam Boiler
Pressures to
250 PSI
2. Low NOx System
Parker was the first manufacturer
to achieve SCAQMD Rule 1146.2
NOx Certification. Initial installations began in 1991 and to date
thousands of Low NOx boilers are
on-line providing reliable operation for our customers.
3. Durable Low NOx Burners
Parker heavy duty premix metal
fiber burners not only provide the
lowest emissions possible but also
provide long durable service life.
4. VFD
Variable Speed Blowers for electrical energy savings on 2-Stage
or Modulating units (standard over
15HP).
5. Low Cost, Efficient Operation
The staggered tubing design provides a multi-baffled heating sur-
face to increase efficiency. The
Premix system offers precise fuel
air control for optimum efficiency.
6. Fast Heat-Up
Our boiler requires less than ten
minutes to heat up to 100 PSI from
a cold start which is a considerable time and fuel saver.
7. Accessible Internal
Inspection
Cabinet doors can easily be
removed in a matter of minutes,
making the internal boiler, drum,
tubes, and burners readily accessible. Easy to remove gasketed
access plugs are provided at both
ends of every tube. Boiler inspections can be accomplished quickly
and at low costs.
SCAQMD
Certified
to 1146.2
8. Ease of Inspection and Repair
Any boiler may eventually require
re-tubing depending on care and
operating conditions. Re-tubing
does not require special tools,
skills or welding as is necessary
on most boilers designed with
rolled tubes.

THE PARKER DESIGN
A time proven product backed by
one of the largest and most successful manufacturers of packaged steam 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 places of mechanical and operating efficiency before shipment.
9. Codes
All boilers are built in accordance
with the ASME Power & Heating Boiler Codes, Sections I & IV.
Boilers above 15 PSI are furnished
with the “S” Stamp and Trim.
Boilers for 15 PSI are normally
furnished with the “H” Stamp and
Trim. All Boilers are inspected
103L Steam Boilers 7-25 HP
and registered with the National
Board of Boiler and Pressure Vessel Inspectors. All individual gas
and electrical controls are Certified or UL Listed. All Low NOx,
outdoor, propane and natural gas
fired models are ETL Listed as
“Industrial and Commercial Gas
Fired Packaged Boilers” and certified to UL795.
All units are provided with trim
and controls to meet ASME CSD-1
standards for “Controls & Safety
Devices for Automatically Fired
Boilers”. In addition, all units also
meet the standards of the International Conference of Building Officials, the International Association
of Mechanical & Plumbing Officials and the Uniform Mechanical
Code.
