Bend both the corrugated pipes toward the fl ue connection
on the water heater. Pull and connect the inner corrugated
pipe to the water heater’s fl ue tube reducer with hi-temp
red silicone (included) and gear clamp. Make sure this
connection is tight and leak proof (see Figure 24).
*The sealant between the inner corrugated pipe and water
heater’s fl ue tube reducer must be hi-temp red silicone
or other material suitable for 600°F continuous service.
Note: If you are using the vent restricter plate, the inner
vent pipe is to go over the side legs and down the stops.
