- Derate the maximum boiler input by 3% when using
the maximum equivalent length of 2 inch (60 mm)
vent piping on Solo 110 & Excellence 110.
- The 2 inch vent system requires a 1 inch clearance
to combustibles
- Use long sweep elbow to limit pressure drop and to
avoid excessive vent temperatures.
- In 2 inch 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
PVC vent system. The installer must also utilize
