Series 8H/8HE EFFICIENT CAST IRON COMMERCIAL WATER BOILER

High Performance & Long Term Reliability

Burnham Commercial’s commitment to quality and dependability
continues with the Series 8H/8HE. The features and eciency of the
8H/8HE boiler make it ideal for single and multiple boiler applications.
Oering space heating, or a combination of heating and domestic
hot water, the Series 8H/8HE has a compact design which easily
adapts to existing piping arrangements, boiler room requirements,
and system heating needs.

American-Made Cast Iron Construction

Burnham Commercial’s unique cast iron
formula has an extremely high silicon
content, making it stronger and more
exible. It oers better thermal shock
resistance and greater heat transfer
capabilities than other cast iron products.

• MANUFACTURED WITH QUALITY

Casting Solutions operates a state-of­the-art foundry, in Zanesville, Ohio,
ensuring quality and availability of
boiler sections.

• CAST IRON NIPPLE DIFFERENCE

The gaskets that other manufacturers
use to connect boiler sections can
break down if they come in contact
with oils, boiler ue gases, corrosion
inhibitors, pump lubricants, and
antifreeze. Burnham Commercial is
committed to safety, reliability and
durability. That’s why the Series 8H/8HE
uses cast iron nipples instead of
gaskets. The Series 8H/8HE’s cast iron
nipples remain unaected by those elements, ensuring long life and
eliminating costly repairs. Cast iron nipples expand and contract
with the sections they connect, ensuring the overall integrity of
the section assembly.

• HEAT EXCHANGER DESIGN

The cast iron heat exchanger on the
Series 8H/8HE features a pinned
heating surface. These multi-faceted
pins allow the heat generated from the
combustion process to be transferred to
the cast iron from a number of angles, which contributes to the
boiler’s overall eciency. A vertical ue design extracts heat while
maintaining low draft losses.

• DELUXE INSULATED JACKET

The jacket on the Series 8H/8HE is lined
with three inches of insulation. This
serves to reduce jacket and standby heat
losses, further conserving energy. The
jacket itself is powder coated, insuring a
scratch resistant, long lasting nish.

Two Packaging Options

Knockdown 8H/8HE units are easy to
handle and maneuver at the job site.
Knockdown units are supplied in a crate
which includes an assembled block with
separate cartons containing jackets and
components (shown). Packaged and wired
units are ready to install out of the crate.
A reinforced shipping container protects
against damage.

Modular Optional Equipment

Water Manifolds

Factory fabricated manifolds are available as
a convenience to the installer. The manifolds
are lightweight and forgiving of minor piping
misalignments common to multiple boiler
installations. Available as two-module or
three-module manifolds. For installations of
four or more modules in a row, the manifolds
can be joined together as required. Applicable
to primary-secondary or parallel piping
arrangements.

Flex Couplings

Easy to install ex couplings are available to
facilitate piping connections. They accommodate
misalignments between pipes and permit up
to a total of 8º angular misalignment at each
connection while maintaining a leakproof seal.
Flex couplings reduce installation time and
reduce labor costs.

*Ratings shown are for installations at sea level and elevations up to 2,000 feet. For elevations above 2,000 feet, ratings should be reduced at the rate of four percent (4%) for each 1,000 feet above sea level.

1. When ordering, use prex P for packaged and K for knocked-down. Use sux NSP for natural gas, standing pilot; NEI for natural gas, electronic ignition; PSP for LP gas, standing pilot; PEI for LP gas, electronic ignition.

2. Net I=B=R ratings shown are based on normal I=B=R piping and pickup allowance of 1.15. Consult the Burnham Commercial website for installations having unusual piping and pickup requirements such as intermittent
system of operation, extensive piping systems, etc.

3. 15 foot height is measured from top of drafthood to top of chimney.
