² Wide radius elbow.
³Vent sizing for Canadian installations over 4500 ft (1370 m) above sea level are subject to acceptance by the local authorities having jurisdiction. NAÐNot Allowed; pressure switch will not make.
NOTES:
1. Do not use pipe size greater than those specified in table or incomplete combustion, flame disturbance, or flame sense lockout may occur.
2. Size both the
3. Assume two 45° elbows equal one 90° elbow. Long radius elbows are desirable and may be required in some cases.
4. Elbows and pipe sections within the furnace casing and at the vent termination should not be included in vent length or elbow count.
5. The minimum pipe length is 5 ft for all applications.
6. Use
b. Reposition neoprene inducer housing outlet cap and clamp to appropriate unused inducer housing connec- tion. Tighten clamp.
WARNING: Inducer housing outlet cap must be in- stalled and fully seated against inducer housing. Clamp must be tightened to prevent any condensate leakage. Failure to follow this warning could result in electrical shock, fire, personal injury, or death.

VENT EXTENSION PIPE
Some furnaces are supplied with a PVC vent extension pipe
NOTE: See label on vent extension pipe for proper installation. This pipe may be shortened if an elbow is used to connect vent extension tube to
3.Working from furnace to outside, cut pipe to required length(s).
4.Deburr inside and outside of pipe.
5.Chamfer outside edge of pipe for better distribution of primer and cement.
6.Clean and dry all surfaces to be joined.
7.Check dry fit of pipe and mark insertion depth on pipe.
NOTE: It is recommended that all pipes be cut, prepared, and preassembled before permanently cementing any joint.
8.After pipes have been cut and preassembled, apply gener- ous layer of cement primer to pipe fitting socket and end of pipe to insertion mark. Quickly apply approved cement to end of pipe and fitting socket (over primer). Apply cement in a light, uniform coat on inside of socket to prevent buildup of excess cement. Apply second coat.
