The IMPERIAL MFG GROUP USA INC GV0394 is a 26-gauge galvanized steel furnace pipe section measuring 7 inches in diameter by 24 inches in length. This straight pipe section is used in single-wall B-vent and Type-B style venting assemblies for gas-fired heating appliances. The 26-gauge galvanized construction provides corrosion resistance suitable for residential and light commercial venting applications. HVAC technicians and sheet metal contractors install this pipe to connect furnaces, boilers, or water heaters to their flue venting systems. It ships in a package of 10 sections, making it practical for new installations or service calls requiring multiple runs.
This furnace pipe section is used in gravity-type and mechanically assisted venting systems for gas-fired appliances. Typical install scenarios include connecting a furnace flue collar to a masonry chimney thimble, building out a vent run across a mechanical room, or replacing deteriorated sections of an existing single-wall metal vent system. The 7-inch diameter accommodates mid-range residential and small commercial appliance venting requirements. It is suited for installations where code-compliant single-wall metal vent pipe is acceptable per the applicable fuel-gas code.
Designed as an OEM-style replacement and new-construction single-wall galvanized furnace pipe for gas appliance venting systems requiring a 7-inch diameter vent connector.
Installation must be performed by a qualified HVAC technician or sheet metal contractor in accordance with the International Fuel Gas Code (IFGC) and local authority having jurisdiction requirements. Shut down and allow the appliance to cool completely before removing or replacing any vent sections. Single-wall metal vent pipe must maintain required clearances to combustibles as specified by the appliance manufacturer and applicable code. Secure all joints with sheet metal screws and seal per the manufacturer and code requirements before returning the system to service.
