on both ends of the wall thimble (on the inside and outside of the wall)
through which intake and vent pipes are passed. They will prevent the
intake and vent pipes from being pushed or pulled.

Horizontal Vent Termination

Adhere to the following for installation:
1. The vent termination is joined to the vent pipe outside the wall. Use the
same joining procedures for vent pipe and ttings. The termination of the
vent system must be at least 12 inches (304.8 mm) above the nished
grade, or at least 12 inches (304.8 mm) above normal snow accumulation
level (for applicable geographical areas). The termination of the vent
system shall not be located in tra c areas such as walk ways, adjacent
buildings, operable windows and building openings unless the venting
system is at least 7 ft (21.3 m) above nished grade, (National Fuel Gas
Code, ANSI Z223.1). The vent terminations must be at least 4 feet (1.22
m) horizontally from electric meters, gas meters, regulators, and relief
equipment. See Figure 9.
2. When installing inlet and exhaust terminations on the same wall, the
exhaust outlet must be installed 3 ft (.914 m) minimum above and
downwind from air supply inlet to prevent exhaust recirculation. Under
certain wind conditions, some building materials may be a ected by 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.
3. Do not locate the vent termination too close to shrubbery as ue products
may stunt their growth or kill them.
4. The minimum vent height should extend at least 3 ft (.914 m) above the
roof, or at least 2 ft (.609 m) above the highest part of any structure within
10 ft (3.04 m) of the vent.
5. If the exhaust vent terminates within 10 ft (3.04 m) horizontally of the
air inlet, the exhaust vent must be at least 4 ft (1.22 m) above the inlet.
Dimensions listed above and those illustrated are minimum, and may or
may not be su cient for conditions at a speci c job site.
6. To prevent the possible re-circulation of ue gases, the vent designer
must take into consideration such things as prevailing winds, eddy zones,
building con gurations, etc. Fulton cannot be responsible for the e ects
such adverse conditions may have on the operation of the boilers. 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.
