Metal-fab MF-5DIHPTA Direct Vent Ihp Adapter

Product Description

The METAL-FAB MF-5DIHPTA is a direct vent IHP adapter designed to transition between venting systems in residential and light commercial heating applications. This adapter connects direct vent appliance collars to IHP-compatible vent pipe assemblies, maintaining a sealed combustion pathway that keeps flue gases isolated from conditioned air. Licensed HVAC technicians and gas appliance installers rely on this type of fitting when integrating or replacing direct vent furnaces, boilers, or water heaters where IHP-style termination or pipe sections are part of the existing venting layout.

This adapter is suited for direct vent heating systems that require a secure, airtight transition fitting at the appliance connection point. It is typically installed during new appliance commissioning or when replacing a failed or incompatible adapter in an existing IHP direct vent assembly. The 5-inch nominal diameter makes it appropriate for mid-range residential gas appliances that specify a 5-inch direct vent collar.

Key Features

• Designed for direct vent IHP venting systems with a 5-inch nominal diameter
• Provides a sealed transition between the appliance collar and IHP vent pipe sections
• Maintains combustion air and flue gas separation required by direct vent system design
• Engineered as an OEM-style adapter for straightforward field replacement

Compatibility

Designed as an OEM-style replacement adapter for 5-inch direct vent IHP venting assemblies used with residential gas appliances.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified gas appliance installer in accordance with the appliance manufacturer instructions and applicable local codes, including IFGC requirements. Shut off gas supply and disconnect power to the appliance before beginning any venting work. Ensure all vent joints are properly seated and secured before restoring gas and power. Do not modify the adapter or use it outside the direct vent IHP system it is specified for.
