9.2 General Venting Requirements Model EP-100,
EP-200 and EP-300 Series Pumps
This heater must be vented in accordance with the
rules contained in this manual and with the following
national codes and any state, provincial or local
codes which may apply:
United States: Refer to National Fuel Gas Code
NFPA 54/ANSI Z223.1 - latest revision.
Canada: Refer to Natural Gas and Propane
Installation Code CSA B149.1 - latest revision.
Any portion of vent pipe passing through a
combustible wall must have an approved thimble
to conform with the above listed codes.
Vent pipe must be sloped downward away from the
pump ¼'' every 10' (3 m).
The bottom of the vent or air intake terminal shall not
be located less than 1
'
The vent shall not terminate less than 7
above grade where located adjacent to public
walkways.
Vent terminal must be installed at a height sufficient
to prevent blockage by snow, and building materials
protected from degradation by flue gases.
Secure all joints with #8 x 3/8 sheet metal screws.
Seal all joints with high temperature silicone sealant.
Vent terminal must be beyond any combustible
overhang.
9.2.1 United States Requirements
Vent must terminate at least 3
forced air inlet located within 10
Vent must terminate at least 4
4 (1.2 m) horizontally from, or 1
'
door, operable window, or gravity air inlet into any

9.2.5 Length Requirements
See EP-100, EP-200 or EP-300 Pump Series
Installation, Operation and Service Manuals for
complete venting options.
Vent lengths are allowed as follows:
EP-300 Vent
Vent Length
Size
6" (15 cm) -
Up to 10' (3 m)
1 elbow
7" (18 cm) -
Up to 25' (8 m)
3 elbow
8" (20 cm) -
Up to 50' (15 m)
3 elbow
Seal all pipe joints with high temperature silicone
sealant in the vent pipe. Insulation and additional
sealing measures will be required.
Optional heat exchanger lengths are considered as
vent length for length determination.
Subtract 15' (4.6 m) of maximum allowed vent or
outside air duct length per vent elbow if more than
three are used.
9.2.6 Vent Material Recoendations
Vent recommendations:
1. Porcelain coated tubing 4'' (10 cm) O.D.
(P/N 9141030D)
2. Heat treated aluminized tubing 4'' (10 cm) O.D.
(P/N 91409408)
Heat treated aluminized tubing 6'' (15 cm) O.D.
(P/N E0009105)
3. Single wall flue pipe - minimum 26 ga.
(Not suitable for modulating and condensing
system designs.)
4. Schedule 40 ASTM A53 (Latest Edition) grad B
ERW black steel pipe.
NOTE: 4" (10 cm) O.D. Porcelain coated tubing (P/N
9141030D), 4" (10 cm) O.D. Heat treated aluminized
tubing (P/N 91409408), and 6" (15 cm) O.D. Heat
treated aluminized tubing (P/N E0009105) are
equivalent to single wall flue pipe.
