Notes:
1) Max vent lengths shown also apply to the intake. For example, Vent Option #1 may have up to 60ft of vent pipe and also up to 60 ft
of intake pipe.
2) First 30” of vent and vent Elbow connected to boiler must be CPVC. Downstream vent pipe can be PVC except as noted in text.
3) PVC Terminal coupling and inlet elbow may be offset on snorkels as shown in Figure 7.6.
4) For models 80 and 100: Make increase in vent diameter from 2 to 3” at boiler collar (before first elbow). Reduce intake diameter
from 3” to 2” at intake collar.
