Specific installation regulations for side-wall and vertical terminations, respectively, are described in
the following two sections (Sections 3.2 and 3.3).
3.2. INSTALLATION PROCEDURE FOR VENTING SYSTEM THROUGH
WALLS
The minimum distances from adjacent public walkways, adjacent buildings, operable windows and
building openings shall not be less that those values specified in the National Fuel Gas Code, ANSI
Z223.1 and/or CAN/CGA B149, Installation Codes.
Minimum clearance of 4 feet horizontally from, and in no case above or below, unless a 4-foot (1.22
m) horizontal distances is maintained, from electric meters, gas meters, regulators and relief
equipment.
Refer to the notes below and Figure 9, when determining the location of the vent outlet.
a) At least 12 inches above finished grade, or at least 12 inches above the normally expected
snow accumulation level in geographical areas where snow accumulates. With a vent
termination clearance of at least 4 feet from any air openings into a building.
b) In Massachusetts, when side-wall venting is used, the vent termination must be located a
minimum of 4 feet above grade.
c) At least 3 feet (92 cm) above any forced air inlet located within 10 feet.
d) At least 4 feet horizontally from electric meters, gas meters, regulators and relief equipment.
e) For horizontal runs, keep vent pipes away from any combustible material, electric wires, and
building insulation.
f) Do not terminate vent over public walkways or over an area where condensate or vapor could
create a nuisance or hazard or could be detrimental to the operation of regulators, relief
valves, or other equipment.
g) Do not locate the vent termination too close to shrubbery as flue products may stunt growth or
kill them.
h) Some building materials may be affected by flue products expelled near unprotected surfaces.
Sealing or shielding of exposed surfaces with a corrosion resistant material (such as aluminum
sheet) may be required to prevent staining or deterioration.
See the National or Canadian Codes listed at the beginning of these instructions for additional
information on termination location.
