Power Direct Vent / Sealed Combustion

Standard Features

• Power Direct Venting System - This 2-pipe closed combustion

system utilizes a stand alone vent to exhaust the byproducts
of combustion, and a separate air intake to provide fresh
combustion air to the unit. Vents to an outside wall using
3” or 4” PVC or CPVC pipe.

• Flammable Vapor Sensor - Sensor detects Flammable Vapors

and will not allow burner operation if vapors are present. The
sensor will also detect ongoing flammable vapor events and
prevent burner operation if present.

• Spark to Pilot Ignition System - The control utilizes a spark

to pilot ignition system. This saves fuel by only operating the
pilot during a hot water demand.

• Microprocessor Control - Electronic control constantly

monitors water temperature and burner status to consistently
and accurately maintain water temperature.

Water Heaters

• Non-CFC Foam Insulation - Improved formulation provides

uniform tank coverage with a thick blanket of insulating
foam. This non-CFC polyurethane closed cell foam minimizes
standby losses and maximizes heat retention.

• Glass-Lined Steel Tank - The durable glass lining assures

lasting protection against rust and corrosion while providing
clean, clear hot water. This tank is automatically formed,
rolled, and welded to assure a continuous seam for the glass
lining. Each tank is triple-tested to ensure quality.

• Heat Traps - Factory installed, minimizes heat loss

through piping.

• Dielectric Nipples - Factory installed waterways protect the

tank from corrosive action between dissimilar metals, while
providing piping convenience.

• Side Tappings- Provided for space heating applications.

• Temperature & Pressure Relief Valve

• Brass Drain Valve

• 6 Year Limited Warranty*

(See warranty for details)

• 10 Year Extended Warranty Available

(In residential applications)

* 3 year limited warranty on tank and 1 year limited warranty on Parts

when installed in commercial applications

• Concentric Vent Termination (optional) - 3" vent kit

allows for the air and vent to be terminated vertically or
horizontally through a single opening.
