REQUIREMENT: The United States Coast Guard, Training Center Cape May has a requirement to replace a quantity of six (6) in kind of Lochinvar Boilers for the Galley &

Gymnasium Buildings.

(1) Lochinvar Power-Fin Boiler – Replacement boilers shall have a 85% thermal efficiency rating and meet the Lochinvar PBN2001 specifications.

(2) Performance – The Lochinvar PBN2001 Power Fin boilers will replace the existing

Lochinvar boilers and will be used to heat Galley & Gymnasium buildings and produce hot water for the buildings.

(3) Lochinvar Power-Fin Boiler –

Manufacturer: Lochinvar

Model: PBN2001-M13; QTY 6 each.

2.000,000 BTU/hr Input Power-Fin Boiler.

1. General

Commercial boiler(s) shall be supplied in accordance with the plans and specifications, with ratings as listed in the Power-Fin water heater dimensions and specifications and shall be

Lochinvar Model PBN2001PM.

1.1 The unit heater(s) shall be up to 85% thermal efficient, set up for Natural Gas (M13) firing controls, with smart system digital operating controls.

1.2 Optional Equipment shall include; Boiler to include low water cut off w/ manual reset, high

& low gas pressure switch w/ manual reset, boiler circulator, outdoor and system sensors, outdoor reset package, Bacnet Communication Gateway, Modbus Communication kit,

1.3 Voltage 120 vac, 1 phase, 60 hz, power supply.

2. Standard Features

The standard features shall include the following; all bronze circulating pump, on/off switch, flow switch, ASME temperature & pressure relief valve, temperature and pressure gauges, test valves, adjustable high limit (with manual reset), automatic reset high limit.

3. Heat Exchanger

The water containing section shall consist of a heat exchanger constructed of a "Fin Tube" design, with straight copper tubes having extruded integral fins spaced seven (7) fins per inch.

These tubes shall be "rolled" securely into glass-lined, cast iron headers. There shall be no bolts, gaskets or "O" rings in the head configuration. Removable access plugs shall be provided on the heat exchanger headers for the purposes of inspection, cleaning or repair. Water Heater drains shall be provided, having external access. The heat exchanger shall be mounted in a stress free jacket assembly in order to provide a "free floating design" able to withstand the effects of thermal shock. The WATER HEATER shall bear the ASME "HLW" stamp for 160 psi working pressure and shall be National Board listed. The complete heat exchanger assembly shall carry a five (5) year limited warranty against failure caused by defective workmanship or material.

4. Smart System Features

The WATER HEATER shall feature the “Smart System” control with a 2-line, 16 character LCD display, password security, pump delay with freeze protection, pump exercise and PC port connection. The WATER HEATER shall allow 0-10 VDC input connection for BMS control and have built-in “Cascade” to sequence and rotate while maintaining modulation of up to eight water heaters without utilization of an external controller. Supply voltage shall be 120 volt / 60 hertz / single phase.

Local communication, programming and a display of operating and alarm status conditions shall be accessible through the Smart System control panel. The Smart System control panel shall contain an on/off main power switch, a digital display of a temperature functions, the operational status of the WATER HEATER, or an active alarm fault. Data points visible in the digital display include inlet water temperature, outlet water temperature, water temperature differential, percent firing rate, set-point temperatures and set-point differential. Operational status shall be displayed for Off, Standby, Pre-purge, Ignition, and Post-purge. Fault status shall be provided for high limit, gas pressure (optional), low water, blocked drain, louver proving, and air pressure switch status.

5. Delivery Units shall be delivered to U.S. Coast Guard, Training Center Cape May, 1 Munro Avenue, Cape

May, NJ 08204-5002.
