Project Replace Existing Furnace with New High-Efficiency Natural Gas Furnace at Big Flats, NY Plant Materials Center, Shop/Warehouse Building.

Location:

USDA NRCS Big Flats Plant Materials Center 3266 State Route 352 Corning, NY 14830

General Information

1.0 Scope of Work

This project covers the removal of the existing heating unit and installation of a new, high-efficiency (AFUE rating of 95% or more) natural gas furnace to provide reliable heating for the 2851 sq. ft. warehouse/shop building, at the location mentioned above. The work will include all necessary labor, materials, and testing to ensure safe and optimal operation.

Removal and disposal will be off-site by contractor. Pictures are in attachment. All work shall be performed in accordance with all applicable codes, and standards (OSHA, NEC, NFPA, ASHRAE).

2.0 Background

The current system, installed in 1990, is a Rheem up flow, natural gas furnace (model number-RGDA-17EA-JR/ serial number EN3D107 M3989 6972). The current unit is not functioning properly and upon inspection as well as age of unit, needs to be replaced with a new, high-efficiency natural gas unit. Current unit is 131,000 BTU’s.

Contractor Requirements

3.0 Technical Requirements / Tasks

Note: All waste material and debris shall become the property of the contractor. The contractor shall remove and dispose of all waste in accordance with all codes and regulations

Pre-Installation:

Site inspection and load calculation to confirm capacity. Use Manual J from American Society of Heating, Refrigerating, and Air-Conditioning Engineers; or other approved engineering method to calculate heating load estimates and select the furnace.

Verify gas supply pressure.

Confirm venting path per NFPA 54 (National Fuel Gas Code) and manufacturer specs.

Removal & Disposal Disconnect and remove the existing furnace.

Properly dispose of old equipment in compliance with local regulations..

Remove solar system piping that is no longer needed and cap and pipes and lines correctly. See photos on attachment.

Equipment Supply Furnace-Provide and deliver an adequate natural gas furnace for space and square footage.

Minimum AFUE rating of 95% BTU input/output-

Modulating heat stages Ductwork

Reuse as-is, seal all connections, and make sure insulation is adequate and upgrade where necessary.

Inspect piping for leaks prior to installing insulation.

iii. Clean existing ducts.

iv. If the existing ductwork is undersized for the new equipment, recommend modification and include in quote.

c. Thermostat

i. Install a programmable thermostat that is compatible with new furnace and rewire as needed.

ii. Keep in current position.

d. Install CO detector

i. Each carbon monoxide detector as required shall comply with NFPA 720 and be ANSI/UL 2034 listed and IAS certified.

4. Installation

a. Install furnace on existing or new platform, as required.

b. Connect to existing natural gas line, ensuring leak-free fittings.

c. Integrate with existing ductwork; modify or seal as needed for efficiency and compliant with local building codes and standards

d. Connect to electrical supply and thermostat controls.

e. Connect Category IV venting with PVC/CPVC piping and condensate drain.

f. Install gas shut-off valve, sediment trap, and flexible connector.

g. Wire to dedicated 120V circuit with proper grounding.

h. Installations must adhere to the clearances to combustible materials to which the furnace has been design certified. Clearances must also accommodate an installation’s gas, electrical, and drain trap and drain line connections.

i. It is the responsibility of the installer to follow the manufacturers’ recommendations and to verify that all vent/flue piping and connectors are compatible with furnace flue products.

j. Additionally, it is the responsibility of the installer to ensure that all piping and connections possess adequate structural integrity and support to prevent flue pipe separation, shifting, or sagging during furnace operation.

5. Testing & Commissioning

a. Perform combustion analysis and adjust for optimal efficiency.

b. Test safety controls, ignition system, and airflow.

i. Before proceeding with electrical connections, ensure that the supply voltage, frequency, and phase correspond to that specified on the unit rating plate. Power supply to the furnace must be NEC Class 1 and must comply with all applicable codes.

ii. The furnace must be electrically grounded in accordance with local codes or, in their absence, with the latest edition of The National Electric Code, ANSI NFPA 70 and/or The Canadian Electric Code CSA C22.1.

c. Verify thermostat operation and temperature output.

d. Combustion analysis to verify CO levels < 100 ppm.

e. Measure temperature rise within manufacturer’s range.

f. Verify static pressure and airflow per design.

6. Cleanup & Handover

a. Remove and dispose of old equipment and debris from the work, daily.

b. Provide operation instructions and maintenance recommendations.

c. Site cleanup- Broom-clean work area upon completion

d. Filters must be provided, sized and installed properly by the installer. Filters must comply with UL900 standards.

7. Documentation:

a. Provide as-built drawings, equipment manuals, and warranty forms.

b. Complete inspection checklist.

c. Include manufacturer’s warranty documentation.
