SPECIFICATION FOR DOMESTIC WATER HEATERS

Power Combustion, Low NOx, Gas-Fired Water Heaters with Nickel-Plated Storage Tanks

Furnish and install MAXIM power combustion gas water heater(s) as manufactured by PVI Industries, LLC of Fort Worth, Texas. Supply quantities and model numbers as indicated on the plumbing schedule.

Gas and Electrical Consumption

The water heater will operate at a minimum of 82% thermal efficiency. The water heater will comply with paragraph 7.2.4.4, the thermal efficiency, the standby loss, and all other 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. All tank connections will be non-ferrous. 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.

Tank 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 a forced-draft power burner with a gas train meeting the following agency requirement for the input specified:

___ UL (standard)

___ FM

___ IRI

___ Other ______________________

Burner and heating section will be certified to operate with NOx emissions not to exceed 30 ppm corrected to 3% O2 (at or above 400,000 Btu) and 55 ppm corrected to 3% O2 or 40 nanograms per joule (below 400,000 Btu). Water heater will be a category I, non-condensing appliance. It will be UL listed for use with non-pressurized, type B venting material.
