line of high efficiency
commercial gas heaters gives you all the advantages
of copper-finned tube heat exchanger technology plus the
benefits of a sealed combustion system. Every Copper-Fin
model offers four major advantages: higher efficiency,
smaller footprint, smaller vent diameters and a wide
variety of venting options.

Outstanding thermal efficiency

Copper-Fin2 gas heaters offer a remarkably high 89%
thermal efficiency. This means that 89¢ out of every fuel
dollar goes into heating the water, dramatically reducing
the operating cost of the equipment. Copper-Fin
this efficiency through the combination of an advanced
fan assisted combustion system and an exclusive
gasketless copper-finned tube heat
exchanger. A time tested
and proven combination.

The heat energy from the
combustion process is efficiently
transferred into the water as it passes
through the solid copper-finned tube heat exchanger. The
sealed combustion design of the Copper-Fin
external heat loss. This means that the energy dollars heat
the water, not the mechanical room. It also ensures that the
jacket stays cooler, providing greater safety and requiring
less clearance from combustible walls - just 1” in most
cases.

Meets the toughest air quality standards

Because of our unique fan-assisted

combustion process, the Copper-Fin2
exceeds today’s toughest NOx emissions
requirements. An independent certification
laboratory test gave us a rating of less than

20 ppm —corrected to 3% O2. And less NOx

means a cleaner environment.

Compact design - for installation ease

The Copper-Fin2 is compact
enough to fit through
standard 36”
doorways with
ease. Even
our
2 million
Btu/hr
model is
only 33-1/2”
wide. This

space-

saving
design frees
up more
space in
the mechanical
room.

And our optional Lochinvar Stack
Frame lets you put two units in the
footprint of just one. See our Stack
Frame literature for more details.

Automatic pumped bypass standard

All Copper-Fin2 heaters are equipped with an automatic
high temperature CPVC bypass to ensure proper flow and
return water temperatures to the heater. This results in
longer equipment life and trouble free operation. The CPVC
bypass is provided as standard equipment in a horizontal

configuration.
A vertical
configuration
is also available
offering the
flexibility to
meet mechanical
room space
requirements
or piping
constraints.

Making installation easier...for less

High-efficiency, fan-assisted combustion means you can
use a smaller diameter vent stack — up to 8” smaller than
typically required. This makes installation less expensive
and more flexible.
