SECTION 7: VENTING
7.1 General Venting Requirements
Install the venting in accordance with the require-
ments within this manual and the National Fuel Gas
Code, ANSI Z223.1/NFPA-54 - latest revision and
CSA 22.1 - latest revision. This section provides par-
tial information about this specification with regard to
size and configuration for venting requirements (see
following figures). However, to provide assurance of
proper and safe operation, it is the responsibility of
the installer to make sure the installation is in strict
accordance with all local and national codes.
7.2 Venting the Pump
• The exhaust connection from the pump is 6" (15
cm) diameter.
• Connect the 6" (15 cm) pump boot (provided) to
the 6" (15 cm) flue pipe, using the 6" (15 cm)
band clamp provided.
• Venting from the pump may discharge either hori-
zontally or vertically. Horizontal discharge is
preferred. See Page 17, Figure 16. Vertical dis-
charge must be arranged as shown on Page 18,
Figure 17. Corrosion resistant pipe is required.
• Both horizontal and vertical venting must be sup-
ported by suitable hangers.
• Vent lengths are allowed as follows:
7.3 Horizontal Venting
The vent material must be either heat treated alumi-
nized tubing 6"(15 cm) O.D. (P/N E0009105) or sin-
gle wall flue pipe minimum 26 Ga. Vent length be
limited to less than 20' (6 m). If using vent lengths
greater than 20' (6 m), condensation will form in the
vent pipe. Insulation and additional sealing measures
will be required.
7.3.1 Horizontal Venting Guidelines
• Vent must exit building not less than 7' (2 m)
above grade when located adjacent to public
walkways.
• Vent must terminate at least 3' (1 m) above any
forced air inlet located within 10' (3 m).
• Vent must terminate at least 4' (1.2 m) below 4'
(1.2 m) horizontally from or 12" (30 cm) above
any door, window or gravity air inlet into building.
• Locate vent terminal at least 12" (30 cm) from any
opening through which vent gases could enter a
building.
• Use only corrosion resistant materials for the dis-
charge line from the pump to the point of dis-
charge.
• Vent terminal opening must extend beyond any
combustible overhang.
• Install vent terminal at a height sufficient to pre-
vent blockage by snow.
• Protect building materials from degradation by
flue gases.
• Any portion of flue pipe passing through a com-
bustible wall must be dual insulated and an
approved thimble must be used.
