Installation

The distance of the vent terminal from adjacent public

The maximum and minimum venting length for this

walkways, adjacent buildings, open windows and

building openings must be consistent with the NFGC

Category IV appliance shall be determined per the

(U.S.) or B149 (Canada).

Vents supported only by

NFGC (U.S.) or B149 (Canada).

flashing and extending above the roof more than 5 ft

should be securely guyed or braced to withstand snow

The diameter of vent flue pipe should be sized accord-

and wind loads.

 

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.
