! WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,
and strict adherence to applicable
jurisdictional/professional codes and
regulations.
Fulton cannot assume responsibility
for an air intake or exhaust
arrangement where Caliber boilers
are common vented with any other
type of equipment.
Cements for plastic pipe are
 ammable liquids and should
be kept away from all sources of
ignition. Proper ventilation should
be maintained to reduce the hazard
and to minimize breathing of cement
vapors. Avoid contact of cement with
skin and eyes.
Assure all electrical connections are
powered down prior to attempting
replacement or service of electrical
components or connections of the
boiler.
4. Seal the pipe to the thimble  ange with adhesive material.
5. Install two pipe retaining clamps around the intake as well as vent pipes
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.
 Vent Termination
Adhere to the following for installation:
1. 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 intake and exhaust terminations in such a way that
it does not become blocked due to snow, ice, and other natural or man-
made obstructions.
2. 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. See
Figure 12. Dimensions provided are minimum, and may or may not be
su cient for conditions at a speci c job site.
3. Consider the harmful e ects to landscaping/shrubbery from the slightly
acidic nature of  ue gas condensate when locating the vent termination.
In addition, adhere to the following for Horizontal Installations:
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.
2. When installing inlet and exhaust terminations on the same wall, the
exhaust outlet must be installed a minimum of 4 feet (1.22 m) 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.
In addition, adhere to the following for Vertical Installations:
1. 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.
