EP-100 PUMP INSTALLATION, OPERATION AND SERVICE MANUAL

SECTION 8: VENTING
8.1 General Venting Requirements
Install the venting in accordance with the
requirements 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 partial information about this specification
with regard to size and configuration for venting
requirements (see Page 17, Figure 15 and Page 17,
Figure 16). 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.
8.2 Venting the Pump
• The exhaust connection from the pump is 4" (10
cm) diameter.
• Connect the 4" (10 cm) pump boot (provided) to
the 4" (10 cm) flue pipe, using the 4" (10 cm) band
clamp provided. Connections to flue pipe larger
than 4" (10 cm) require use of an appropriate
taper pattern reducer (not supplied).
• Venting from the pump may discharge either
horizontally or vertically. Horizontal discharge is
preferred. Corrosion resistant pipe is required.
• Both horizontal and vertical venting must be
supported by suitable hangers.
• Vent lengths are allowed as follows:
• See Section 8.4 for vent material
recommendations.
8.3 Horizontal Venting
If using vent lengths greater than 30' (9 m),
condensation will form in the vent pipe. Insulation
and additional sealing measures will be required.
Seal all discharge pipe joints with high temperature
silicone adhesive.
8.3.1 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
discharge line from the pump to the point of
discharge.
• Vent terminal opening must extend beyond any
combustible overhang.
• Install vent terminal at a height sufficient to
prevent blockage by snow.
• Protect building materials from degradation by flue
gases.
• Any portion of flue pipe passing through a
combustible wall must be dual insulated and an
approved thimble must be used.
8.4 Vent Material Recommendations
(in order of preferred use)
1. Porcelain coated tubing 4" (10 cm) O.D.
(P/N 9141030C)
2. Heat treated aluminized tubing 4" (10 cm) O.D.
(P/N 91409408)
3. Single wall flue pipe (corrosion resistant) -
minimum 26 Ga.
VENT LENGTH VENT SIZE
Up To 25' (8 m) 4" (10 cm) vent - 3 elbows
Up To 50' (15 m) 5" (12.5 cm) vent - 3 elbows
WARNING
Carbon Monoxide Hazard
Pump must be vented to the
outside.
Heaters must be installed
according to the installation
manual.
Failure to follow these
instructions can result in death
or injury.
