
Ensure the vent is located where it will not be exposed to prevailing winds.

In all roof venting applications, exhaust discharge must point away from the pitch of the roof.

To prevent water leakage, install adequate roof flashing where the pipe enters the roof.

Do not locate vent over public walkways, driveways, or parking lots. Condensate could drip and freeze, resulting in a slip
hazard or damage to vehicles and machinery.

Due to potential moisture build-up, sidewall venting may not be the preferred venting option. To save time and cost, carefully
consider venting installation and location.

Horizontal lengths of exhaust vent must slope back towards the water heater not less than ¼" per foot to allow condensate to
drain from the vent pipe.

The exhaust vent must terminate where vapors cannot make accidental contact with people or pets, or damage shrubs or
plants.

In vacant chimney applications, install and seal a rain cap over existing chimney openings.

All piping must be fully supported. Use pipe hangers at a minimum of 4 foot intervals to prevent sagging of the pipe where
condensate may form.

Do not use the water heater to support any piping.
