Flue Pipe Extension That Adds the 3 ft of Vertical Run Frost Fighter's Manual Calls For
The flue collar on a Frost Fighter IDF or IDH heater is short. The manual requires the flue to end in a vertical section at least 2 ft long, and calls a 36 in. extension before the rain cap highly advisable. The Frost Fighter 48807 Flue Pipe Extension is that pipe: 3 ft of 6 in. galvanized flue pipe, sold without a cap.
Key Features and Benefits
- The Frost Fighter flue pipe extension provides the 36 in. of pipe before the rain cap that the IDF manual calls highly advisable for outdoor use.
- Galvanized single-wall steel with one crimped end that nests into the heater's 6 inch flue pipe collar or the next pipe section. The open end fastens onto the heater's flue.
- The 6 in. diameter matches every Frost Fighter IDF and IDH heater. No adapter or reducer is needed.
- Sold without a cap, this Frost Fighter flue pipe extension suits a buyer who already owns a 48808 vent cap or needs a replacement pipe only.
Pipe, Cap, or Both
Four Frost Fighter heater parts cover the flue, and each serves a different purpose. If you need the pipe and cap as one chimney pipe extension, the 48809A ships with the rain cap already attached. The 48807 is pipe only, paired with a separate 48808 vent cap.

How It Fits
Frost Fighter's IDF manual gives a two-step instruction for the Frost Fighter flue pipe extension. First, fasten the rain cap on the end of the 3 ft pipe. Then fasten the open end onto the heater's flue collar. Joints must be tight. The pipe cross-section must not be smaller than the flue collar. Horizontal runs rise 1 in 10 away from the heater, and no elbow may exceed 90 degrees.
Which Heaters Use It
This flue pipe extension fits every Frost Fighter heater with a 6 in. flue. Frost Fighter's manuals give a 6-inch flue pipe on the IDF350, IDF500, IDH200QR, IDH350QR, IDH400QR, and IDH500QR. It does not fit the IHS series, which vents at 8 in.; the IHS700H and IHS700P take the 78809A. DF direct-fired heaters have no flue.

Which end of stove pipe goes up when installing a flue extension?
