matching pump capacity to vent size. Length of pipe is
equal to total of vertical and horizontal length.
Vertical Venting
Pump Venting Instructions
If the vent pipe is over 30' (9 m) long, insulate it to minimize condensation. Seal all discharge
pipe joints with General Electric RTV 106 or Permatex Form-A-Gasket red high-temperature
silicone adhesive or equivalent.
For horizontal venting:
1. Vent must exit building not less than 7 feet above grade when located
adjacent to public walkways.
2. Vent must terminate at least 3 feet above any forced air inlet located
within 10 feet.
3. Vent shall terminate at least 4 feet below, 4 feet horizontally from or one foot
above any door, window or gravity air inlet into building.
4. Locate vent terminal at least 12" from any opening through which vent
gases could enter a building.
5. Use only corrosion resistant materials for the discharge line from the pump to the
point of discharge.
6 Vent terminal opening must extend beyond any combustible overhang.
7. Install vent terminal at a height sufficient to prevent blockage by snow.
8. Protect building materials from degradation by flue gases.
9. Any portion of flue pipe passing through a combustible wall must be dual insulated
or an approved thimble must be used.
