System Piping Testing; Before Leaving The Installation - FULTON VSRT Series Installation And Operation Manual

ROOF VENT TERMINATION
Adhere to the following for installation (see Figure 15):
1. The minimum vent height should extend at least
6 feet (1.8 m) above the roof, or at least 6 feet (1.8
m) above the highest part of any structure within
10 feet of the vent.
2. When installing inlet and exhaust terminations
above the roof, the exhaust outlet must be
installed 4 feet (1.22 m) minimum above and 4
feet (1.22 m) minimum downwind from air supply
inlet to prevent exhaust recirculation (see Figure
16).
SIDE WALL VENT TERMINATION
Adhere to the following for installation (see Figure 17):
OTE: The vent termination is joined to the vent pipe
–
outside the wall. Use the same joining procedures for
vent pipe and fittings.
1. When penetrating a non-combustible wall, the
hole through the wall must be large enough
to maintain the pitch of the vent and provide
sealing. Use adhesive material to seal around the
vent on both sides of the wall. When penetrating
a combustible wall, a wall thimble must be
used. See Figure 17 for installation instructions.
Minimum wall thickness through which vent
system may be installed is 3.25 inches (8.26 cm).
Maximum wall thickness through which vent
system may be installed is 20 inches (50.8 cm).
2. The termination of the vent system must be at
least 12 inches (30.48 cm)above the finished
grade, or at least 12 inches (30.48 cm) above
normal snow accumulation level (for applicable
geographical areas).
3. The termination of the vent system shall not be
located in traffic 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 finished grade, (National Fuel Gas
Code, ANSI Z223.1).
4. The vent terminations must be at least 4 ft (1.22
m) horizontally from electric meters, gas meters,
regulators, and relief equipment.

5. When installing inlet and exhaust terminations
on the same wall, the exhaust outlet must be
installed 4 feet (1.22 m) minimum above and 10
feet (3.05 m) minimum downwind from air supply
inlet to prevent exhaust recirculation.
6. Under certain wind conditions, some building
materials may be affected by flue 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.

System Piping Testing

Upon completion of the installation, adhere to the
following for system piping testing:
1. Perform a pressure test.
2. Perform soap tests at all welds and joints to
ensure that the system is free from leaks.

Before Leaving the Installation

Before leaving the installation, adhere to the following:
1. Check all controls to ensure they are operating
properly.
2. Cycle the boiler several times.
3. Make sure the installation complies with all
applicable codes.
