Please make sure the vent- air intake system, properly reassembled and sealed after any dis- assembling, or repairing
them. ( Follow up vent manufacturer, instruction for re sealing)
In all installations avoid vent termination locations where excessive debris or snow could accumulate leading to blocking
of the vent terminals. Vent terminals should avoid being installed where the building exterior could be tarnished from
the flue gases, a shield or another location should be considered. The vent terminals shall be installed according to
the instructions as provided terminals shall not be less than 2 inches [50mm] from the wall surface or more than 10
inches [254mm] from the terminal to the wall. For high traffic locations, the vent terminal shall be guarded. According
to the national gas codes [CSA B149 & ANSI Z223.1/NFPA 54] a vent shall not terminate:
● Directly above a paved walkway or driveway which serves two or more buildings or where the flue gas condensation
or vapor could create a hazard or improper operation of regulators, relief’s or valves or any other device.
● Above or below any electric or gas meter, regulators & relief devices unless a 4ft [1.2m] horizontal clearance
distance to be maintained.
● Less than 7ft [2.1m] above any paved sidewalk or driveway.
● Less than 6ft [1.8m] from any combustion air inlet source from any nearby building.
● Less than 4 ft. [1.2m] above a meter/regulator assembly horizontally from a vertical centerline of the regulator
vent outlet to a maximum vertical distance of 15ft [4.6m].
● Less than 1ft [03m] above grade or normal snow level in the area is expected.
● Less than 3ft [0.9m] from windows, doorways, and combustion air supplies nearby buildings or other appliances.
●
Under a veranda, porch or deck, unless [1] the veranda, porch or deck is fully open on at least 2 sides underneath.
[2] The distance between the top of the terminal and the grade is greater than1ft (0.3m)
For other than direct vent appliance , the appliance must be located as close as practicable to a chimney or gas
vent. The appliance should be located in an area where leakage of the tank or connection will not result in damage
to the area adjacent to the appliance or to lower floors of the structure. When such locations cannot be avoided ,it
is recommended that a suitable drain pan, adequately drained, be installed under the appliance. The pan must not
restrict combustion air flow.
