Vent Pipe Slope

All horizontally installed portions of a vent system shall have a slope (upwards for Category II, III, or IV

appliances) not less

than 1/4” (6.4 mm) every 12 inches (305 mm) to prevent collection of condensate at

TO CUT PIPE FOR SINGLE WALL ONLY

The pipe may be cut to length on the non-expanded end using aviation snips or a hacksaw with a 24 tpi blade. Make certain to

keep the cut end square & cylindrical. The cut end must be filed or sanded smooth before joining (see images 9 & 10).

Make certain to account for the correct insertion depth when measuring for a cut length of pipe.

2 INCH INSERTION DEPTH FOR DIAMETERS 3 INCH THRU 12 INCH

3 INCH INSERTION DEPTH FOR DIAMETERS 14 INCH THRU 24 INCH

i) Measure 2 inches (for diameters 3 inch thru 12 inch) or 3 inches (for diameters 14 inch thru 24 inch) from cut end

and draw a line to indicate depth insertion.

ii) Insert male end into female end to within ¼ inch of the drawn line to achieve full depth insertion.

Cut pipe joint connections not meeting the full insertion criteria can cause personal injury, death or

substantial property damage.
