Lengths
• For all venting applications, PVC/CPVC, AL29-4C®,
SS or Polypropylene, the length must not exceed
the lengths listed in Table 8 below.
• For PVC/CPVC or AL29-4C® vent systems, reduce
the maximum allowable length for each elbow as
follows:
• 3 feet for every 45º elbow
• 5 feet for every 90º elbow
• For polypropylene vent systems, reduce the maxi-
mum allowable length for each elbow as follows:
• 5 feet for every 45º elbow
• 10 feet for every 90º elbow
1.4. Vent Restrictions
1.4.1 2 Inch (60 mm) Vent System Restrictions
• Derate the maximum boiler input by 3% when us-
ing the maximum equivalent length of 2 inch (60
mm) vent piping on Solo 110 & Excellence.
• The 2 inch vent system requires a 1 inch clearance
to combustibles.
• Use long sweep elbows to limit pressure drop and
to avoid excessive vent temperatures.
• In 2 inch PVC vent applications, the rst 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 PVC vent system. The installer
must also utilize primer and glue that is cer-
tified 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, or death.
1.4.2 3 Inch (80 mm) Vent System Restrictions
Derate the maximum boiler input of the PRESTIGE Solo
250 by 3% when using the maximum equivalent length
of 3 inch (80 mm) vent piping.
