Venting Installation Tips

Support piping:

·horizontal runs- at least every five (5) feet.

·vertical runs - use braces:

·under or near elbows

Follow items listed below to avoid personal injury or property damage.

·Cut nonmetallic intake pipe with fine-toothed hack- saw.

·Do not use nonmetallic intake pipe or fittings that are cracked or damaged.

·Do not use nonmetallic intake fittings if they are cut or altered.

·Do not drill holes, or use screws or rivets, in non- metallic intake pipe or fittings.

To make metallic vent joints:

·Do not install seams of vent pipe on bottom of runs.

·100% Seal all joints and seams with high temper- ature silicone sealant.

WARNING: Examine the venting system at least once a year. Check all joints and vent pipe connections for tightness, corrosion or deterioration.

NOTE: The words "Flue Exhaust", "Flue" and "Exhaust Vent" are used interchangeably.
