Venting and Combustion Air Installation
For Delta PERFORMANCE applica-
tions that may exceed the 100 feet maxi-
mum allowable equivalent length for the
venting system, contact Triangle Tube
Engineering Department for additional
information on how the appliance can be
adjusted to the application.
-
For each elbow included in the system,
the maximum allowable linear length
must be reduced as follows:
• Each 90º elbow within the system is
the equivalent of 10 linear feet.
• Each 45º elbow within the system is
the equivalent of 5 linear feet.
It is recommended that the installer uses the
same number of elbows and length of piping
on the venting system and the combustion air
inlet.
