Innovation in Design
The AQUAS commercial pool package is a dramatic advancement in the design of pool heating systems.
The AQUAS package is a factory assembled system featuring a free-standing boiler piped to a dedicated
cupro-nickel pool heat exchanger.
The AQUAS indirect pool heating design gives you…
• Effective heat transfer from a high efficiency, condensing modulating boiler.
• A complete factory assembled package reduces installation cost and time.
• Separating the pool water from the direct-fired heat source reduces maintenance
and promotes longer equipment life.
• Reliability and performance with a positive user experience.
Pool Heat Exchanger - A durable industrial grade cupro-nickel heat exchanger
design provides effective heat transfer. The pool water flows through a series of cupro-nickel

heated water from the boiler. This simple design keeps the

highly efficient heat transfer.
THE AQUAS POOL PACKAGE DELIVERS GREATER HEAT TRANSFER
In addition, this innovative design allows for increased overall thermal transfer exceeding the input rate of the boiler.
A 1,500,000 Btu/hr pool package can match the heating power of a 2,000,000 Btu/hr direct fired pool heater.
This design delivers a higher "Thermal Duty Rating" and reduces the amount of fuel burned to generate comfortable
pool temperatures.

The AQUAS pool package is constructed with
stainless steel modulating condensing boilers
that deliver up to 97% thermal efficiency. Low

Direct-Venting up to 100 Feet
AQUAS offers multiple venting options and tremendous
flexibility for placement of units within the building,
because it permits direct-vent air intake and exhaust
runs up to 100 equivalent feet using either PVC, CPVC,
Polypropylene or AL29-4C stainless steel vent pipe.
Intake and exhaust runs can terminate horizontally
through a sidewall or vertically through the roof.

Insii d e the
e Boill err
The AQUAS is an innovative pool package that begins with the most
advanced boilers in the industry today. The AQUAS boiler is a high
efficiency, condensing boiler perfectly suited for the low water
temperatures typical of pool heating. The following are some of the
exciting features you get with the advanced boiler design.
Negative Regulation Technology
Negative Regulation or Neg/Reg technology is a unique combination of combustion
on
air blower and dedicated gas valve that work together to deliver a precise mixture of gas and air to the burner. With Neg/
Reg, the gas/air mixture remains perfectly balanced for clean combustion throughout the modulating input range with
supply gas pressures as low as 4 inches water column.
“Fail-Safe” Direct-Spark Ignition
With each call for heat, two electrodes will ignite the gas/air mixture and a third electrode will monitor the flame signal.
The SMART SYSTEM and SMART TOUCH control programs will lock out if ignition does not occur and provide you with an
immediate alarm signal.
Two-in-One Stainless Steel Heat Exchanger

Direct Vent with PVC
Reduce your installation cost, save time and effort by installing the AQUAS pool package with
PVC pipe. The AQUAS pool package offers a variety of vent designs in your choice of PVC,
CPVC, Polypropylene or Stainless Steel vent material. What’s more, you can Direct Vent the
AQUAS. By drawing the combustion air into the appliance with a dedicated intake pipe, the
AQUAS is protected from corrosive pool chemicals that could damage the combustion system.
Outdoor Rated Models
The AQUAS OXN400-801 models are specially trimmed for outdoor installation. The jacket is sealed
and rated to protect the boiler against the elements. Pump covers, air intake covers and a speciallydesigned vent assembly complete the package to allow for easy installation outdoors.
