CAUTION	Do NOT use grease or other lubricant on the
CAUTION	vent seals. Only water may be used for this
	purpose. Grease or other lubricant can make
	the seal brittle or cause tearing of the seal
	surface which can result in ﬂue gas leakage.

7.Slide the vent pipe through the wall strap and insert it into the elbow. Tighten the clamp (FIG. 2-3).

8.Install the termination into the top of the vent and tighten the clamp.
