Bend both the corrugated pipes 

toward the flue connection on the 

water heater. Pull and connect the 

inner corrugated pipe to the water 

heater’s flue tube reducer with hi-

temp red silicone (included) and gear 

clamp. Make sure this connection is 

tight and leak proof (see Figure 12). 

*The sealant between the inner 

corrugated pipe and water heater’s 

flue tube reducer must be hi-temp red 

silicone or other material suitable for 

600°F continuous service.

NOTICE:

 If you are using the vent 

restricter plate, the inner vent pipe is 

to go over the side legs and down the

NOTICE: 

To ensure good exhaust gas 

flow, bend vent piping using a smooth, 

easy curve as shown in Figure 12 

through Figure 14. Do not use reverse
