SPECIFICATION FOR DOMESTIC WATER HEATERS

Power Combustion, Low Nox, Gas-Fired Water Heaters with Polymer-Lined 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 when tested by an independent laboratory 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. 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 lining will:

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

be third-party tested to 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 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.

PV 6314 specifications

PVI Industries has made significant strides in the electric vehicle (EV) market with its innovative product, the PV 6314. This advanced electric bus is designed to meet the increasing demand for sustainable public transportation solutions, reflecting PVI's commitment to eco-friendly technologies and efficient design.

At its core, the PVI PV 6314 is powered by a state-of-the-art electric drivetrain. The bus is equipped with a high-capacity lithium-ion battery pack, offering impressive range and performance. With a full charge, the PV 6314 can travel up to 300 kilometers, making it a practical solution for urban and suburban routes. This extended range allows operators to serve longer distances without the need for frequent recharging, enhancing overall operational efficiency.

One of the standout features of the PV 6314 is its regenerative braking system. This technology captures energy during braking and redirects it back into the battery. As a result, the vehicle not only reduces energy consumption but also extends the lifespan of its braking components. This innovation contributes to lower maintenance costs, which is a significant consideration for fleet operators.

The PV 6314 is designed with passenger comfort and accessibility in mind. The bus offers a spacious interior, featuring wide aisles and low-floor configuration to accommodate all passengers, including those with reduced mobility. Comfort-enhancing features include climate control systems and ergonomic seating that ensure a pleasant travel experience for riders.

In terms of connectivity, the PV 6314 is fitted with advanced telematics systems. These systems provide real-time data monitoring, allowing operators to track vehicle performance, battery status, and location. This data not only facilitates efficient fleet management but also helps in optimizing routes, reducing downtime, and minimizing operational costs.

Safety is paramount in the design of the PV 6314. The bus is equipped with a comprehensive suite of safety features, including anti-lock braking systems (ABS), electronic stability control (ESC), and a robust chassis designed to protect passengers in the event of a collision. Additionally, the PV 6314 includes advanced driver assistance systems (ADAS) that enhance the driver's awareness and response capabilities.

In conclusion, the PVI Industries PV 6314 is a leading example of contemporary electric bus technology, combining sustainability, efficiency, comfort, and safety. Its impressive range, innovative features, and focus on passenger experience make it a strong contender in the growing electric transportation market, poised to shape the future of public transit.
