ing to the NFGC (U.S.) and Appendix B of B149
(Canada). The minimum flue pipe diameter for con-
ventional venting is: 4 in. (102mm) for Models 300 and
500, and 6 in. (152mm) for Model 850.
The connection from the appliance vent to the stack
must be as direct as possible and shall be the same di-
ameter as the vent outlet. The horizontal breaching of
a vent must have an upward slope of not less than 1/4
inch per linear foot from the heater to the vent termi-
nal. The horizontal portions of the vent shall also be
supported for the design and weight of the material
employed to maintain clearances and to prevent physi-
cal damage or separation of joints.
NOTE: A vent adapter (field-supplied) may be re-
quired to connect the Category IV vent to the boiler.
Termination
The vent terminal should be vertical and should termi-
nate outside the building at least 2 ft above the highest
point of the roof that is within 10 ft. The vent cap
should have a minimum clearance of 4 ft horizontally
from and in no case above or below (unless a 4 ft hori-
zontal distance is maintained) electric meters, gas
meters, regulators and relief equipment.	Fig. 20: Vertical Venting
