Vent specifications
Establish vent clearances that comply with the vent
manufacturer's specifications and all applicable
national/local codes.
Venting specifications
Condensate drain requirements
An external condensate drain (not supplied with the
heater) must be installed under the following
conditions:
• All vertical terminating vent installations.
• Horizontal terminating vent installations where the
total linear vent length is greater than 6 feet (1.8 m).
• Vent installations where any section of the exhaust
vent pipe passes through an unconditioned space.
Minimum combustion air and exhaust pipe
length
The minimum exhaust pipe length is 3 feet (1m) of
straight vent pipe. The minimum combustion air pipe
length is one 90° elbow.
Maximum combustion air and exhaust pipe
length
The following tables (Tables 5 & 6) display the
maximum allowable straight pipe lengths for
combustion air and exhaust piping with consideration to
the number of elbows used.
Step 1: If using the twin pipe penetration system, refer
to table 5. If using the concentric vent kit
system, refer to table 6.
Step 2: Total the number of 90° elbows and 45°
elbows used on the exhaust piping.
Step 3: Use this value in the appropriate table to
determine the maximum straight exhaust pipe
length allowed.
Step 4: Total the number of 90° elbows and 45°
elbows used on the combustion air piping.
Step 5: Use this value in the appropriate table to
determine the maximum straight combustion
air pipe length allowed.
