Where condensate vapor could cause damage or could be detrimental to the operation of regulators, relief valves, or other equipment.
2
When locating vent terminations, consideration must be given to prevailing winds, location, and other conditions which may cause recirculafion of the combustion products of adjacent vents
Recirculation can cause poor combustion, inlet condensate problems, and accelerated corrosion of the heat exchangers
3
Avoid venting under a deck or large overhang

Disk usage-Unless otherwise specified, use perforated disk assembly (factory-supplied
in loose parts bag). If one disk is stated, separate 2 halves of perforated
assembly and use shouldered disk half When using shouldered disk half, install screen side toward iNet box.
tWide radius elbow
SVent sizing for Canadian installations over 4500 ft (1370 m) above sea level are subject to acceptance by the local authorities having judsdiction.
NA-Not 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 combustion-air and vent pipe independently, then use the larger diameter for both pipes
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 3-in. diameter vent termination kit for instNlations requiring 4-in diameter pipe.
