SPECIFICATION FOR DOMESTIC WATER HEATERS

Condensing, Gas-Fired Water Heaters with Nickel-Plated Storage Tanks

Furnish and install the following POWER VT® gas water heater(s) as manufactured by PVI INDUSTRIES, INC of Fort Worth, Texas.

	Model	Btu/h	GPH Recovery	Storage
Qty	Number	Input	40° to _____°F	Tank
___	____________	__________	________	_______ gallons
___	____________	__________	________	_______ gallons
___	____________	__________	________	_______ gallons

Efficiency

The water heater will operate at a thermal efficiency of 94% when tested to ANSI Z21.10.3. The water heater will comply with paragraph 7.2.4.4, the thermal efficiency and the standby loss requirements of ASHRAE 90.1-1999.

Pressure Vessel and Heating Surfaces

The water heater will be a vertical fire tube design that is constructed and stamped in accordance with Section IV, Part HLW of the ASME code. Both the storage and heating sections of the water heater will be National Board Registered for a working pressure of 150 psi and will be pressure tested at 1-1/2 times working pressure. The fireside of the heating surfaces will be of boiler-grade steel. The waterside of the heating tubes will be sealed in copper. The heating tubes will be rolled, beaded, and seal welded into the tube sheets. The combustion side of the tube sheet will be insulated by a layer of ceramic fiber that will protect the tube sheet from both thermal stresses and failure that can result from the accumulation of scale and precipitants.

Lining

The tank will be a plated with electroless nickel (EN). Plating will occur after the pressure vessel is completely fabricated and all welding is completed. The EN plating will be a high-phosphorus (10%) and nonporous composition suitable for submersion service (ASTM B733 standard may be used as a guideline). The finished lining will not require sacrificial anode rods. For additional protection against galvanic corrosion, which may occur within the potable water system, the EN plating may have a high-dielectric-strength polymer overcoat.

Burner and Venting

Combustion will be provided by an induced-draft power burner that can operate with as little as 4-1/2 inches water column of gas pressure. The water heater will be UL listed for use with plastic venting materials. The heater will be capable of directly venting inlet air rated @ 120 equivalent feet and exhaust rated as follows: 4” vent - 50 equivalent feet on 1 MBtu/h model, 100 equivalent feet for other inputs; 6” vent – 390 equivalent feet on 1Mbtu/h model, 500 equivalent feet for other inputs.

The burner will be equipped with a gas train meeting the specifications of:

___ UL (standard equipment)

___ FM

___ IRI

___ Other ______________________
