SPECIFICATION FOR DOMESTIC WATER HEATERS

Condensing , Low NOx, Gas-Fired Water Heaters with Polymer-Lined Storage Tanks

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

Emissions

NOx emissions will not exceed 30 ppm when corrected to 3% O2 (for inputs greater than 399,000 Btu). NOx emissions will not exceed 55 ppm when corrected to 3% O2 (for 399,000 Btu input). These levels will be certified by independent agency.

Gas and Electrical Consumption

The water heater will operate at a minimum of 94% thermal efficiency when tested to ANSI Z21.10.3. 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. 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 lining will:

be applied only after the tank is completely fabricated and all welding is completed. consist of multiple applications of a high-temperature fluoropolymer.

be third-party tested to and comply with NSF 61 standard.

be continuous and nonporous with no interruptions or discontinuities. require no sacrificial anode rods for protection.

Burner and Venting

Combustion will be provided by an induced-draft power burner with a gas train meeting the following agency requirement for the input specified:

___ UL (standard) ___ FM ___ IRI ___ Other ______________________

Water heater will be a category IV, condensing appliance, UL listed for use with CPVC vent or AL 29-4C stainless steel vent. Burner will be configured to accept ____ room air _____ direct inlet combustion air. Water heater will operate

with a minimum gas pressure of 4 ½ inches water column.
