Vent/Combustion Air Equivalent Lengths; Vent Restrictions; Inch (60 Mm) Vent System Restrictions - IDEAL Exalt Solo 110 Manual

CHAPTER 1 - PRE-INSTALLATION REQUIREMENTS
NOTICE
• A specific vent adapter may be required to
transition from the boiler vent outlet adapter
to the specific polypropylene vent system.
Contact the
manufacturer
information.
• When using Polypropylene for the vent
system, PVC or CPVC pipe meeting the
listed requirements in this manual may be
utilized for the combustion air piping.
1.4.

Vent/Combustion Air Equivalent Lengths

• For all venting applications, PVC/CPVC, AL29-4C®
Stainless Steel or Polypropylene, the length must
not exceed the lengths listed in Table 1 below.
NOTICE
• The 90° elbows used to terminate the
combustion air inlet and vent outlet
exterior of the building have been
accounted for in the maximum allowable
vent or combustion air piping length
provided in Table 1below .
• For PVC/CPVC or AL29-4C® Stainless Steel vent
systems, reduce the maximum allowable length
from Table 1 for each elbow as follows:
• 3 feet (0.9 m) for every 45º elbow
• 5 feet (1.5 m) for every 90º elbow
• For polypropylene vent systems, reduce the
maximum allowable length from Table 1 for each
elbow as follows:
• 5 feet (1.5 m) for every 45º elbow
• 10 feet (3 m) feet for every 90º elbow

Vent Restrictions

1.5.1 2 Inch (60 mm) Vent System Restrictions

• The 2 inch (60 mm) vent system requires a 1 inch
(2.5 cm) clearance to combustibles.
• Use long sweep elbows to limit pressure drop and
to avoid excessive vent temperatures.
• In 2 inch (60 mm) PVC vent applications, the first 7
equivalent feet of the vent system must utilize CPVC
material.
To avoid vent failure, the installer must use
CPVC vent material for the first 7 equivalent
feet of a 2 inch (60 mm) PVC vent system. The
installer must also utilize primer and glue that
is certified for both PVC/CPVC materials.
Failure to comply with this requirement can
cause the venting system to fail, resulting in
substantial property damage, serious injury,
• The 3 x 2 Inch reducer required for 2 Inch
venting has been accounted for in the
maximum allowable vent or combustion air
piping length provided in Table 1 below.
• LP Conversions of all Exalt models MUST be
installed using a 3" (80 mm) vent / combustion
