Questions & Answers

Q:Can this be used for a vent pipe for natural gas furnace and hot water heater

Answer This Question

A:  No, a single wall, 30 gauge pipe should not be used for this. Heavier Gauge Pipe is used to vent boilers, furnaces and hot water heaters. You can check with the product manufacturer's for their requirements.

    Answer This Question

    A:  If you want to have a return inside a studded wall you will need to change over to a rectangular duct equivalent to the 6” round one. Calculate the 6” area using geometry (pie…3.16) and then buy the rectangular duct that is at least the same area or larger that’ll fit inside your walls. Once down to where your return vent needs to be you will need to create the opening and create a terminal box to connect the grill. You will need some metal bending tools, to cut and put back drywall etc etc. If you are not skilled in these areas you ought to contact a handyman company proficient in this area.

        A:  A 6” duct will likely not fit inside a wall as studs are usually only 3.5” in depth. A 6” duct is adequate but only as an additional supplemental return, typically an 8” or larger is used. Boxing in a return duct is fine but make sure you screw any joints together and then seal the joints with aluminum duct tape.

          Q:How come the crimping is on the inside, rather than the outside? Does this make a difference when trying to fit that end into a non-crimped, smooth 6" duct?

          A:  The crimping side is the male end. It goes inside a non crimped pipe

          by|Dec 22, 2022

            A:  The crimping process runs the metal through and crimps both the metal all at once inside and outside. The crimped end should fit in a non-crimped end. If you have any other inquiries about our Master Flow products please email warrantyllbp@gaf.com
