WORK

FOR

B1005 & B1007 CE Compound Gas

Valve Replacement

606 S. Aspen St.

Buckley SFB, Colorado

80011

COA: 14 May 2026

1.0 Scope of Work

1.1 Primary Objective

The contractor shall provide fully qualified technicians and all specialized tools to replace six (6) gas control valves suspected of damage from a faulty gas regulator.

1.2 Gas valve install, System Inspections and Re-commissioning

The contractor shall thoroughly review all equipment’s manufacturer Installation and Operation manuals prior to beginning any work. After reviewing all manuals, the contractor will inspect and carefully install all gas valves with the valve assemblies specified in the manufacturers parts replacement lists (attached). Extra precautions will be taken, and the following will be avoided to prevent potential damage to new gas valves or systems. all valve assembly replacements will be done according to manufacturer’s specifications.

• Cross threading any connections or fittings.

• Using excessive pipe sealant that can restrict gas flow.

• Applying excessive force directly to the new gas valve assembly or body while installing.

Following valve replacement, the contractor shall:

• Conduct comprehensive leak checks on all affected equipment.

• Perform a full safety inspection of all gas-fired equipment, including internal components such as burners, gas valves, heat exchangers, and all electrical/mechanical parts.

• Perform multiple leak checks on each piece of equipment, both while the units are static and again while under full operational load with 460th CES HVAC leadership & Fire Department present.

• Re-commission all boilers and water heaters after a full operational test to certify their continued safe operation.

1.3 Deficiency Reporting

Upon completion of the re-commissioning, the contractor will deliver a deficiency report detailing any compromised components or units requiring further attention. If additional work or a full system replacement is recommended, the contractor must provide a separate, detailed report with clear justification for the recommendation.

1.4 Contractor-Furnished Items

The contractor is responsible for providing all necessary materials and equipment, including but not limited to:

• OEM Gas control valves, assemblies, fittings, gaskets, and valve replacement kits. (must use manufacturer's part replacement list.)

• All specialized tools required to re-commission units, perform gas pressure tests, conduct combustion analysis, and complete operational tests of all gas-fired equipment.

• NOTE: All replacement parts must come from a manufacturer approved authorized distributer / supplier.

1.5 Governing Standards

All work shall be performed in strict accordance with the manufacturer's specifications and the latest editions of the following codes and standards:

• UFC 3-410-01: Heating, Ventilating, and Air Conditioning Systems

• UFC 3-420-01: Plumbing Systems

• ASME Boiler and Pressure Vessel Codes

• All applicable state and local laws/codes

UFC criteria can be accessed via the Whole Building Design Guide at https://www.wbdg.org/ffc/dod/unified-facilities-criteria-ufc.

2.0 Project Logistics & Scheduling

• Period of Performance: 60 days after Receipt of Award

• Building Downtime: No specific building-wide downtime is required. Individual units can be isolated for work as needed, ensuring continuous operations.

3.0 Technical & Compliance Requirements

3.1 Definition of Qualified Labor

The contractor must ensure all technicians are certified and licensed to service and repair commercial boilers in accordance with the standards listed in Section 1.5. Furthermore, all technicians must possess specialized certification and experience with the following specific equipment models:

• Rinnai Tankless Water Heaters: Model # REU-KBD3237FFUDC-US (C199i)

• Lochinvar Knight Boilers: Model # KBN601

• Lochinvar Knight Boilers: Model # KBN286

3.2 System Pressure Testing Protocol

The contractor shall verify the maximum and minimum inlet gas pressures for each unit via its data plate before commencing work. Inlet pressure tests must be performed before and after new valve installation. Under no circumstances shall any valve be exposed to pressures exceeding the manufacturer’s maximum inlet pressure specification. After installation, the contractor will verify the working inlet gas pressure with all systems running to ensure valves are functioning within manufacturer specifications.

3.3 Reporting & Deliverables

https://www.google.com/url?q=https%3A%2F%2Fwww.wbdg.org%2Fffc%2Fdod%2Funified-facilities-criteria-ufc

Upon project completion, the contractor shall submit a final report containing the following detailed information:

• Pre- and post-installation gas pressure readings.

• Results of all leak checks (for both static and operational states).

• A summary of all operational and safety checks performed.

• A complete combustion analysis report.

• A log of all replaced parts.

• A detailed summary of any unit deficiencies discovered during re-commissioning.

3.4 Return of Materials

The contractor shall tag all removed parts with the corresponding unit they were removed from and return them directly to the 460 CES project manager.
