Armor®150,000 to 800,000 Btu/hr Models
The Intelligent Approach to Water Heating
There are several tank-type commercial water heaters on the
market with thermal efficiencies of 95% or higher. They all
promise tremendous savings on operating costs compared to
standard-efficiency units, but none of them truly measures up to
the Lochinvar ARMORTM.
ARMOR is a fully condensing commercial gas water heater. Available
in eight models with inputs ranging from 150,000 to 800,000 Btu/hr,
the ARMOR achieves thermal efficiencies up to 98%.
ARMOR delivers long-lasting life-cycle efficiency surpassing any
commercial unit in its class. When you look beyond the numbers
you’ll discover the many ways that ARMOR technology is in a
class by itself!

Fully Modulating with 5:1 Turndown
ARMOR features advanced Negative Regulation (Neg/Reg)
sealed combustion technology, permitting fan speed to constantly
adjust the volume of fuel and air entering the burner. This ensures
that ARMOR can safely and reliably operate with supply gas
pressure as low as 4 inches water column.
ARMOR is equipped with fully modulating combustion with
5:1 turndown. This means ARMOR can fire as low as 20%
of maximum input when water heating demand is lowest, and
increase the firing rate up to 100% as demand increases. The result
is better overall efficiency and less cycling, compared to all other
tank-type units which are “on-off,” which means they can only fire
at 100% of maximum input.

Stainless Steel Condensing Heat Exchanger
The ARMOR’s stainless steel heat exchanger is built to
ASME Section IV requirements. Its design provides superior
resistance to corrosion caused by
condensation from low entering
water temperatures. Traditional
commercial water heaters will
fail early with low entering water
temperatures; however, with the
ARMOR the lower the supply
water temperature the more
efficiently it performs throughout
the life of the heater.

Shield ® 150,000 to 500,000 Btu/hr Models
96 % Thermal Efficiency for Life
The SHIELD™ commercial water heater delivers best-in-class
innovation from Lochinvar. It operates at 96% thermal efficiency,
with inputs up to 500,000 Btu/hr, and provides a 100% effective
defense against a water heater’s worst enemy—lime scale buildup
inside the tank.
SHIELD uses the industry’s most advanced stainless steel heat
transfer system. Sealed combustion technology delivers a quiet
and environmentally friendly supply of heat to the system. Plus,
with drawdown capacity as much as 15% higher than typical
tank-type heaters, you get more usable hot water than any
other competing models. The result is quiet, long-lasting green
performance…life cycle efficiency that keeps saving money,
year after year.

Long-Lasting Life Cycle Efficiency
High-efficiency tank-type water heaters have one thing that
SHIELD does not, energy-robbing lime scale buildup. This
insulates the water from the heat source, decreasing thermal
efficiency, which increases operating costs. Additionally, the rate
of scaling increases with temperature and usage. Just a ¼” of lime
scale buildup will cause increased fuel consumption and raise
operating costs as much as 25%. Lime scale buildup also requires
periodic acid washes in the tank that will simply result in a shorter
useful life of the equipment.

SHIELD can fire as low
as 20% of maximum

demand is lowest, and
increase to 100% for

This results in better overall
efficiency and less cycling
compared to “on-off” tanktype units that can
only fire at 100%.

Intelli-Fin®1.5, 1.7 & 2.0 MBH Models
The Intelligent Approach to Water Heating
Our 1.5 million, 1.7 million, and 2 million-Btu/hr Intelli-Fin
water heaters are whisper quiet. They are engineered to take
advantage of the power of digital communications. That’s
a powerful advantage, because this capability, along with
Lochinvar’s engineering, means Intelli-Fin provides you with
the lowest total cost of water heater operation.

Pushing the Upper Limits of Efficiency
Independent testing shows that Intelli-Fin reaches up to 97%
thermal efficiency. That means for every energy dollar, 97
cents is converted into useable heat. To achieve this higher
efficiency, Lochinvar utilizes a dual heat exchanger arrangement
to create a heat trap. One heat exchanger surrounds the unit’s
burner, absorbing heat at the point of combustion. A second
heat exchanger captures additional heat as the spent gases are
extracted from the combustion chamber. The position of this
second heat exchanger forces the products of combustion to flow
over it’s entire surface allowing the remaining heat to be absorbed
and transferred to the water.

Intelligent Enough to Speak Your Language
Intelli-Fin is the first water heater designed to be compatible
with LonWorks®, the interoperability language that is fast
becoming the language standard for building management
systems. To enhance this LonWorks performance Lochinvar has
developed a new control, which provides a remarkable amount of
information and the ability to customize equipment for a specific
application. This control along with the Command Display
allows local monitoring of 21 diagnostic points and adjustment
of 6 operational characteristics. If remote system management is
desired, all Intelli-Fin functionality can be accessed, reviewed and
adjusted via a phone line and personal computer.

Adjust Output to Match Demand
Intelli-Fin utilizes variable frequency drive technology to control
gas and air input to the burner, ensuring complete combustion
and enabling infinitely proportional adjustment of Btu/hr output.
In fact, Intelli-Fin can reduce output from 100% to 25% of rated
capacity and efficiently provide heat at any fraction of the load
in between. This variable combustion process combined with
Lochinvar’s new temperature control, accurate to with in 1°F,
enables Intelli-Fin to track the heating load precisely.

Flexibility in Water and Gas Supplies
Intelli-Fin can operate with a minimum inlet gas pressure as low as
4 inches of water column. This reduced input requirement prevents
nuisance operational problems in areas of varying gas supply
pressures. Additionally, the sophisticated heat transfer system of
Intelli-Fin integrates dual heat exchangers with a full automatic
pumped bypass. This design allows Intelli-Fin to operate with return
water temperatures as low as 50°F, providing increased installation
flexibility in applications such as heat pump, snow melting and
radiant floor systems.

An Intelligent Use of Space
Intelli-Fin’s chassis has been engineered so that it makes use of
vertical rather than horizontal space. This allows the smaller
footprint, but the unit is still so compact that it fits in spaces no
higher than 80 inches. For even more convenience, Intelli-Fin offers
several venting options. If your project demands high efficiency,
Intelli-Fin delivers. In fact, it’s virtually impossible to be any better.

Infinite Modulation
With thermal efficiencies up to 87%,
Power-Fin water heaters feature
infinitely modulating burner firing
rates (turndown), precisely matching
the firing rate to domestic water load
requirements. The result is better
overall efficiency and less cycling.
Power-Fin water heaters may be
specified as either 5:1 turndown
(502 - 2001), 2:1 turndown (1501 - 2001), or ON/OFF
(502 - 1302). With 5:1 turndown the burner fires as low as
20% of maximum input when demand is lowest and increases
the firing rate up to 100% as demand increases. Models with
2:1 turndown modulate from 50% to 100% of maximum input.

Gasketless Heat Exchanger
The Power-Fin heat exchanger features an array of 20
or 24 copper-finned tubes surrounding the burner for
maximum heat transfer. Lochinvar also pioneered the
“gasketless” heat exchanger, which eliminates the use
of O-rings and gaskets. Because of the time-proven
reliability of this design, the Power-Fin heat exchanger
is backed by a 5 year limited warranty.

Copper-Fin II® 400,000 to 2,070,000 Btu/hr Models
Thermal Efficiency Is Higher...
While Footprint And Vent Sizes Are Smaller
Lochinvar’s Copper-Fin II® line of high efficiency
commercial gas water heaters gives you all the
advantages of lime scale-free, copper-finned tube heat
exchanger technology plus the benefits of a sealed
combustion system. Every Copper-Fin II model offers
four major advantages: higher efficiency, smaller
footprint, smaller vent diameters and a wide variety of
venting options.

Outstanding Thermal Efficiency
Copper-Fin II water heaters offer a remarkably high 85%
thermal efficiency. This means that 85¢ out of every fuel
dollar goes into heating the water, dramatically reducing
the operating cost of the equipment. Copper-Fin II
achieves this efficiency through the combination of an
advanced fan assisted combustion system and exclusive
gasketless copper fin tube heat exchanger. A time tested
and proven combination.

Meets The Toughest Air Quality Standards
Because of our unique fan-assisted combustion process,
the Copper-Fin II exceeds today’s toughest NOx emissions
requirements. An independent certification laboratory test
gave us a rating of less than 30 ppm — corrected to 3% O2.
And less NOx means a cleaner environment.

Proportional Firing
The Copper-Fin II’s proportional firing lowers your
energy costs and delivers more consistent water
temperatures. Multiple gas valves supply gas to the
burners in stages, and multiple blowers maintain the
proper airflow to ensure the most efficient combustion
at each level of use. Our built-in sequencer controls each
of these functions. With digital accuracy, the sequencer
carefully monitors the need for heat, and as demand
increases or decreases, it automatically adjusts the blower
output and gas valves. As the demand is met, the system
lowers performance gradually, turning off gas valves and
reducing combustion air in direct proportion.

Compact Design - For Installation Ease
The Copper-Fin II 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 Multi-Stack™ frame
lets you put two units in the
footprint of just one

Copper-Fin® 495,000 to 2,065,000 Btu/hr Models
Installation Flexibility and Cost-Savings
With compact sizes that use less floor space than ever before, all
Copper-Fin units are narrow enough to fit through a standard 36”
doorway–an advantage most commercial boilers can’t provide.
Plus, thanks to special insulating materials,
Copper-Fin units require only 3” clearance
from combustible walls. What’s more, our
Multi-Stack frame allows you to install two
units in the area normally required for one.
This makes it easier to fit multiple Copper-Fin water heaters into
cramped mechanical rooms. And you can even use a smaller
diameter vent stack - up to 8” smaller than typically required for
comparable atmospheric boilers - so it saves money as well as
valuable mechanical room space

Unique Copper-Fin Heat Exchanger

Enhanced to Provide Performance
and Serviceability

The Lochinvar Copper-Fin water heater design uses a two-pass
heat exchanger. Water is circulated through a row of highly-efficient, finned copper tubes. The high rate of water flow
creates a scouring action that prevents sediment and lime-scale
buildup so common in conventional water heaters, and the
finned copper tubes allow maximum heat transfer efficiency.

Our newly enhanced Copper-Fin models offer the same reliable
operation, and feature a more service friendly design. The
referenced gas valves are in the upper deck for easy access, and
the electrical and EMS connections have all been repositioned
toward the front of the unit for easier service access.

To create this special heat capability, Lochinvar extrudes the fins
from thick wall copper tubing to precise specifications -exactly 7
fins per inch. The result is an integrally-finned
tube with a heat transfer ratio 9 times
greater than a plain copper
tube.

HeavyDuty
Gasketless
Design
What’s more,
advanced casting processes allowed Lochinvar to develop
a unique one-piece header system. This gasketless design
provides enhanced reliability, improved durability and optimizes
performance - but without the problems or failures so common
to O-rings and gaskets.

Meets The Toughest Air Quality Standards
Because of our unique fan-assisted combustion process,
the Copper-Fin exceeds today’s toughest NOx emissions
requirements. An independent certification laboratory test gave
us a rating of less than 30 ppm —corrected to 3% O2. And less
NOx means a cleaner environment.

The gas valves are referenced to the sealed combustion chamber
to improve operational performance by monitoring the pressure
in the sealed combustion chamber and adjusting gas flow to
maintain the optimum air/fuel mixture. And the built-in air
inlet filter reduces maintenance and improves performance by
trapping dust and airborne particulates that can foul the burners
and blowers. With duel sight glasses (one on each end), you
can easily monitor burner performance and flame characteristics
throughout the entire combustion chamber.
The operator interface panel provides electronic temperature
control and comprehensive diagnostic status, without opening
the control panel. Its user friendly design simplifies service while
providing additional diagnostic information through a series of
LEDs.

Efficiency+® 150,000 to 300,000 Btu/hr Models
Efficiency+ delivers unsurpassed performance, reliability and energy
savings - year after year. While most competitive models peak at 80%
thermal efficiency, the Efficiency+ delivers a remarkable 85% thermal
efficiency, which means that 85¢ out of each fuel dollar goes toward
heating the water, and not up the flue! When you combine the outstanding
thermal efficiency with the scale free operation of the copper-fin tube heat
exchanger and the convenience and safety of direct venting you have a
product that is simply the smartest choice in water heating.
Moreover, when you package the Efficiency+ with a Lock-Temp storage
tank, you get a system that provides high efficiency and high delivery.
The EfficiencyPac is a powerful combination that lowers operating
costs, provides high delivery rates, and offers longer equipment life than
traditional tank type water heaters.

EfficiencyPac® Water Heater
When you depend on hot water to stay in business, you should expect your water
heater to work “smarter,” not harder! Traditional tank-type water heaters build
up lime scale deposits when they heat water. This makes the water heater work
harder, which leads to reduced efficiency, increased fuel costs, and shorter tank life.
Lime scale build-up can cause a typical tank-type unit to fail in as few as 4–5 years.
Sometimes less!
The Efficiency Pac from Lochinvar combines the high efficiency of an Efficiency+
(EW series) water heater with the durability of a Lock-Temp baffled storage tank to
create a water heating system that performs at peak efficiency year after year.
• Thermal Efficiency – the Efficiency Pac delivers a remarkable
85% thermal efficiency. Most tank-type units peak at 80%.
• No Lime Scale Build-up – the Efficiency Pac limits lime scale build-up with
the scrubbing action of water flow through the solid copper-tube heat exchanger.
• Unsurpassed Delivery – the Lock-Temp storage tank employs a baffle that allows
80% tank draw down without a drop in temperature. When combined with an
85% efficient water heater, the results are a First Hour Delivery that can’t be beat
- 274 gallons for an EPN200-85.
• Direct-Venting Convenience – The Efficiency Pac can draw its combustion air
directly from outdoors. This feature prevents contamination from airborne dirt
particles and chemicals, while isolating the water heater from negative air
pressures often found in restaurants and mechanical rooms.

Copper-Fin® 90,000 to 500,000 Btu/hr Models
High efficiency Copper-Fin water heaters combine the benefits of a copper finned tube heat
exchanger with the simplicity of atmospheric combustion to provide a durable, trouble-free
design with quick and easy component removal for service simplicity.
And with the Lochinvar “Better Idea” system, you combine the highly efficient Copper-Fin
water heater with a separate Lock-Temp storage tank and manifold piping. By separating
the water heater and storage tank, stand-by losses are virtually eliminated and operating
efficiency is enhanced.

THERMAL
82 %EFFICIENCY

For additional flexibility, the Copper-Pak starts with a Lock-Temp storage tank and places
a Copper-Fin water heater directly on top in a unique space saving design. The circulator
pump and piping are all in place and the unit is ready to be installed as a single package.

Copper-Pak® Water Heater
The Copper-Pak packs the high efficiency of the Copper-Fin water heater into
a unique space-saving design. It’s an excellent alternative to traditional tanktype water heaters. Shipped complete in one box, with all piping included and
ready for installation.
Think of the Copper-Pak as two separate units stacked on top of each other–a
highly efficient Copper-Fin (CW series) water heater and a dedicated hot water
storage tank. By combining the two in one unique design, we’ve reduced the
footprint. That makes it easier to install in place of conventional tank-type
water heaters.

THERMAL
82 %EFFICIENCY

Plus, thanks to copper finned-tube technology, the Copper-Pak has efficiencies
up to a remarkable 82% – far exceeding most tank type water heaters. In fact,
our 85 gallon - 180,000 Btu/hr model performs as well as most 100 gallon 200,000 Btu/hr tank-type water heaters. It produces just as much hot water, but
at a much lower cost.

SquireTM Indirect Water Heater Models
The Squire uses the power and efficiency of the boiler that heats the home to generate domestic hot water for showers, dishwashing, clothes washing…any hot water demand required. The
efficiency of the boiler used to heat the home can be as much as 20% higher than a direct-fired
tank-type water heater. So why not use that efficiency to “indirectly” provide hot water for all
domestic applications.

Energy Saver Indirect Models
Make your money work for you! By choosing an Energy Saver Indirect
Water Heater, the same energy spent to hydronically heat your home can heat
your domestic hot water. The Energy Saver Indirect Water Heater is a smart
answer to the question of how to keep your fuel costs down.
The Energy Saver Indirect is an indirect-fired, potable water storage vessel.
It accepts heat from an external heat source, such as a Solution or KNIGHT
Heating Boiler. By sharing heat for two purposes, efficiency results.

Standard Features
· Shield Combustion System - Corrosion
resistant chamber redirects air through a
stainless steel flame arrestor plate to
prevent flame rollout and flammable vapor
ignition. A resettable thermal switch shuts
down the burner and pilot operation in the
event of a flammable vapor ignition and
also protects against lint, dust and oil
buildup by shutting down when it detects
significant air restriction.
· Power Vented Exhaust System - The
120 VAC blower fan exhausts the byproducts of combustion directly to the
outside the building through PVC style
pipe, eliminating the need for conventional
chimneys or roof penetrations.
· Side Wall or Vertical Venting - can be
vented horizontally with 2”, 3” or 4” PVC
or CPVC vent pipe, depending on the
model. (See vent chart for max. vent lengths)
· Electronic Spark Ignition - Eliminates
nuisance pilot outages and saves fuel by
eliminating the continuously burning pilot,
while providing solid-state ignition.

· Low NOx Burner - This whisper quiet,
360° burner incorporates aluminized steel
into its die-formed design. The large
burner diameter transfers more heat,
while providing clean and efficient
combustion. Satisfies local codes and
emissions standards.
· Non-CFC Foam Insulation - This
non-CFC polyurethane closed cell foam
minimizes standby losses and maximizes
heat retention.
· Glass-Lined Steel Tank - The tank is
automatically formed, rolled, and welded
to ensure a continuous seam for the glass
lining. The durable glass lining is fused to
the interior of the tank at 1600°F to
assure lasting protection against rust and
corrosion while providing clean hot water.
· Magnesium Tank Saver Anode - High
capacity anode rod provides protection
from the effects of electrolytic corrosion.

· Electronic Thermostat - This accurate
control provides an easy way to reset
water temperature for best economy.
Automatic over-heat safety device is
standard. LED status indicator
simplifies setup and adjustments.
· Heat Trap Nipples - Factory
installed waterways reduce heat loss
in piping, while providing piping
convenience.
· Side Connections for Space
Heating - select models are equipped
with side tappings for space heating
applications.
· Temperature & Pressure Relief Valve
· Brass Drain Valve
· Warranty - Six or Ten year limited
tank warranty. Six year warranty on
parts. (See warranty for details)

Two Lochinvar 990,000 Btu/hr Copper-Fin II® water heaters
stacked for a total capacity of almost 2 million Btu/hr.

Another Innovation from Lochinvar
Lochinvar’s Copper-Fin technology not only makes our water
heaters and boilers more efficient, it means they also have a
smaller footprint. So they save space as well as operating costs.
And now there is a way to get greater flexibility and reliability,
save even more space, and get a system that is perfectly
matched to a facility — thanks to the Multi-Stack System from
Lochinvar.
Match Load and Capacity
With this versatile stand, you can stack almost any combination
of our Copper-Fin, Copper-Fin II, and Efficiency+ water
heaters and boilers. So you can achieve the perfect Btu/hr
capacity for each application.
For example, a facility needs a Copper-Fin II water heater with
a total capacity of 1.6 million Btu/hr. Instead of installing an
oversized 1801 unit or a smaller 1441 model, now you can
combine two units — 991 and 651 models — to exactly match
the facility’s needs.

Plus, the total footprint of this combined system is just over
10 inches wider than the 651 unit alone, making it smaller than
either the 1801 or 1441 model. All thanks to the Lochinvar
Multi-Stack Frame.
Added System Benefits
This modular design provides two other important benefits.
First, it allows for system turndown for greater efficiency when
demand is lower. And second, it ensures against system failure
by utilizing two independent but complementary units.
For indoor residential and light commercial needs or
commercial applications up to 4 million Btu/hr, the Multi-Stack
Frame gives greater flexibility without a significant increase in
stack size or overall system dimensions.
Once you have determined a facility’s requirements and the
exact models needed, utilize the charts provided to calculate
total system dimensions.
Note: Indoor Installation Only
