One part number, one box, no on-site assembly.\u003c\/li\u003e\n  \u003cli\u003eThis Frost Fighter chimney pipe is a triple-wall flue pipe with a stainless steel outer wall. The triple-wall flue pipe holds heat in the exhaust stream, which keeps the draft pulling even in freezing conditions.\u003c\/li\u003e\n  \u003cli\u003eThe 6 in. inner diameter matches every Frost Fighter IDF and IDH indirect-fired heater flue collar.

Joints must be tight, and the pipe cross-section must not be smaller than the collar. Horizontal runs rise 1 in 10 away from the heater. No elbow may exceed 90 degrees. The flue must end in a vertical section at least 2 ft long. Clearance from the flue extension with rain cap to combustibles is 24 in.
