SECTION 2 VTG-IOM-2016-1214 INSTALLATION
undersized common exhaust vent or pressure drop due to the horizontal
run can create a positive pressure common exhaust situation which may
require a mechanical draft assist system.
5. If the common exhaust conguration does not allow for a stable negative
pressure under all operating conditions then a mechanical draft assist
system, such as a variable speed exhaust fan, may be required.
 Venting Terminations
Adhere to the following for installation:
1. All vent pipes and ttings must be installed with appropriate air space
clearances to combustibles. These air space clearances apply to indoor or
outdoor vents—whether they are open, enclosed, horizontal or vertical
or pass through oors, walls, roofs, or framed spaces (See Figures 20 and
21). The air space clearances should be observed to joists, studs, sub
oors, plywood, drywall or plaster enclosures, insulating sheathing, rafters,
roong, and any other material classed as combustible.
2. 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 held responsible for the
eects such adverse conditions may have on the operation of the boilers.
3. The required minimum air space clearances also apply to electrical wires
and any kind of building insulation
4. Listed termination parts must be used.
5. Select the air intake point of penetration where a minimum of 1/4” per foot
(6.35 mm per .3 m) upward pitch can be maintained.
6. It is recommended to install a mesh bird screen, with minimum 1/2” by 1/2”
openings, at the combustion air intake termination. Climates subject to
extreme cold may require alternate congurations to provide an increased
surface area, such a cylindrical screens. Consult your venting supplier for
recommendations.
7. It is important to locate the exhaust termination 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.
 Wall Thimble Installation
Adhere to the following for installation (see Figure 22):
1. The thimble is inserted through the wall from the outside.
2. Secure the outside ange to the wall with nails or screws, and seal with
adhesive material.
3. Install the inside ange to the inside wall, secure with nails or screws, and
seal with adhesive material.

4 CAUTION
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. It is the responsibility of the installer
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.
Do not locate the vent termination too close
to shrubbery as ue products may stunt
their growth or kill them.
The port marked “air” on the SKP25 actuator
cannot be used as a gas vent connection.
Connecting a vent line to this port may
cause operational issues.
