* Disk usage--Unless otherwise stated, use perforated disk assembly (factory-supplied in loose parts bag)
1 Wide radius elbow
$ Vent sizing for Canadian installations over 4500 ft (1370m) above sea level are subject to acceptance by the local authorities having jurisdiction.
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, determine the smallest diameter allowed by the table for each pipe, 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 fl for all applications
