This device must be used only with up to two listed gas-fired appliances equipped with draft hoods, draft diverters, or
barometric draft controls.
Venting system should be installed and supported in accordance with the National Flue Gas Code A.N.S.I.Z223.1, or in
accordance with any local codes. A vent pipe connector shall be supported for the design and weight of the material
employed, to maintain clearances, prevent physical damage and separation of joints. A vent pipe increaser or reducer
may be required for connecting the power venter to the vent system. If needed, place the reducer close to the power
venter. Smaller vent pipe sizes than a chimney-vented system may be used for the vent system.
If mounting venting system near combustible materials, refer to Diagram B for allowable installation clearances.
Clearances are based on an installation using single wall galvanized steel vent pipe. For metal thickness of galvanized
steel pipe connectors, refer to NFPA 211 or NFPA 54 Standards for guidelines. If manufactured double wall vent pipe is
required or used for the installation, clearance should be based on the vent pipes rated clearance. Always check local
code requirements for code restrictions.
Route the vent pipe from the appliance to the power venter using a minimum number of elbows as possible. The
horizontal section of the vent pipe should have a slight upward slope from the appliance to the power venter. For
clearances to combustible materials, multiple appliance venting and other installation requirements, refer to the National
Fuel Gas Code A.N.S.I.Z223.1, and/or any applicable local codes or appliance manufacturer's installation instructions.

To install an outer pipe extension to the SWG power venter, the
end pipe cover on the power venter must be removed. Then, cut a
1-inch square notch into the vent pipe extension before attaching to
the power venter. (See Figure 7) This allows clearance for the
adjustment damper. Install the required length of outer pipe
extension lengths as needed for clearance to combustible
materials. Terminate the outer pipe extension with the end pipe
cover. (See Diagram B.) The table shows minimum allowable
clearances when using single or double pipe systems. When the
outer pipe is extended over the inner pipe use the double pipe
guidelines when determining clearances.
NOTE:
Vent pipe joints
should be secured with at least (3) three sheet metal screws.
