INSTALLATION
 Horizontal Vent Termination
Adhere to the following for installation:
NOTE:  The vent termination is joined to the vent pipe outside the wall. Use
the same joining procedures for vent pipe and fi ttings.
1. The termination of the vent system must be at least 12 inches (30.48 cm)
above the fi nished grade, or at least 12 inches (30.48 cm) above normal
snow accumulation level (for applicable geographical areas).
2. The termination of the vent system shall not be located in traffi c areas
such as walk ways, adjacent buildings, operable windows and building
openings unless the venting system is at least 7 ft (2.1 m) above fi nished
grade, (National Fuel Gas Code, ANSI Z223.1).
3. The vent terminations must be at least 4 ft (1.22 m) horizontally from
electric meters, gas meters, regulators, and relief equipment.
4. When installing inlet and exhaust terminations on the same wall, the
exhaust outlet must be installed horizontally 4 ft (1.22 m) minimum above
and downwind from air supply inlet to prevent exhaust recirculation.
5. Under certain wind conditions, some building materials may be aff ected
by fl ue products expelled in close proximity to unprotected surfaces.
Sealing or shielding of the exposed surfaces with a corrosion resistant
material (such as an aluminum sheet) may be required to prevent staining
or deterioration. Flue should be directed away from surfaces, if possible.
6. The minimum vent height should extend at least 3 feet (0.9 m) above the
roof, or at least 2 feet (0.6 m) above the highest part of any structure within
10 feet of the vent.
7. If the exhaust vent terminates within 10 ft (3 m) horizontally of the air inlet,
the exhaust vent must be at least 4 ft (1.2 m) above the inlet. Dimensions
provided are minimum, and may or may not be suffi
cient for conditions at
a specifi c job site.
8. To prevent the possible re-circulation of fl ue gases, the vent designer
must take into consideration such things as prevailing winds, eddy zones,
building confi gurations, etc. Fulton cannot be held responsible for the
eff ects such adverse conditions may have on the operation of the boilers.
9. It is important to locate the exhaust duct in such a way that it does
not become blocked due to snow, ice, and other natural or man-made
obstructions. If terminating into a prevailing wind, direct elbow upward.
Avoid areas (example: courtyards) where swirling high winds may be
present.
Removing an Existing Boiler
When an existing boiler is removed from a common venting system, the
common venting system is likely to be too large for proper venting of the
appliances remaining connected to it.
