Lochinvar & A.O. Smith 100278058 Adapter
The Lochinvar & A.O. Smith 100278058 Adapter is a critical venting component designed for professional high-efficiency HVACR installations. This DuraVent appliance adapter is engineered specifically to transition between the unit’s flue collar and the vent pipe system, ensuring a gas-tight seal for Category II, III, and IV gas appliances. Built from premium-grade materials, this adapter is compatible with condensing boilers and water heaters from the Lochinvar Knight and A.O. Smith commercial series. It eliminates the need for field-fabricated connections, mitigating the risk of flue gas leakage or condensate corrosion in the venting stack.
When installing the 100278058 adapter, technicians benefit from its precision-machined fit, which integrates seamlessly with the FasNSeal or Special Gas Vent systems. This OEM replacement part is essential for maintaining the pressure integrity of the exhaust system, especially in high-efficiency HVAC equipment where positive pressure and corrosive condensate are constant factors. Relying on this appliance adapter ensures your installs meet strict UL 1738 and ULC S636 venting standards, protecting both the equipment and the facility. For contractors managing Lochinvar boiler maintenance, keeping this adapter in the service truck is a best practice for reliable flue-side repairs.
Key Benefits:
- Precision Compatibility: Designed specifically for Lochinvar and A.O. Smith high-efficiency units, ensuring 100% interface alignment.
- Corrosion Resistance: Manufactured to withstand acidic condensate common in condensing heat exchangers.
- Regulatory Compliance: Supports safe exhaust of Category IV appliances, adhering to building code requirements for gas venting.
- Simplified Installation: Reducer/adapter design facilitates a direct connection, reducing labor hours and the need for messy sealants.
Common Questions:
Is this adapter compatible with PVC venting?
The 100278058 is typically utilized for stainless steel or DuraVent PolyPro systems. Always verify your specific Lochinvar technical manual for approved venting material transitions to ensure compliance.
Can I use this for a Category I appliance?
While engineered for positive pressure venting (Categories II, III, IV), it is critical for a tech to verify the chimney or vent stack pressure rating. This adapter is specialized for condensing systems that require moisture-tight seals.
Does it require additional silicone sealant?
When used with DuraVent FasNSeal components featuring internal gaskets, additional sealant is generally not required, though local mechanical codes and specific boiler flue requirements should be consulted.
