Connecting Power Venter To Appliance - Field Controls 46256400 Manual

3. After determining the location of the venting system termination point (See Diagram A), cut a square hole through the
wall 1" larger than the outer pipe diameter of the power venter. Mount the power venter through the wall, keeping the
outer pipe centered in the hole. (See Figure 3) Fasten the power venter to the outside wall with appropriate fasteners.
Seal the edges of the power venter base plate to the wall with a high temperature silicone sealant. DO NOT enclose
the spaced plates on the power venter body. This will result in reduced cooling of the power venter body. Galvanized
metal sheets may be installed over surrounding building surfaces to protect building materials for degradation by flue
gases. Brick or tile may be placed on the ground below the power venter to protect the soil and vegetation from the
effects of heated exhaust air. The power venter should be placed so that vegetation and other objects are not in direct
contact with the power venter or blocking the outlet. Snow should be cleared from the outlet area as needed. Wood or
vinyl siding should be cut so that the unit mounts directly on the wall board to provide a stable support. If the siding is
greater than 1/2" thick use a spacer plate or board behind the power venter mounting plate. (See Figure 4)
NOTE: If mounting the power venter through a combustible wall material and the flue gas temperature is above 400EF at
the power venter inlet, line the square hole with a piece of corrosion resistant sheet metal or non-combustible material.
The liner piece should be the same width as the wall section. (See Figure 3) The power venter has maximum flue gas
temperature of 550EF at the power venter inlet. Figure 7 shows how the airflow pattern through an SWG reduces the
required clearances to combustibles. For installation in wall thickness over 8-inches, use an SWG Series Through Wall
Extension Kit, Model PEK.
4. Remove the end pipe cover screws on the sides of the outside pipe and
remove end pipe cover. Then mount the backing plate over the outer pipe and
route the flexible conduit and pressure switch tube through the holes provided
in the backing plate. Fasten the backing plate to the inside wall with appropri-
ate fasteners. (See Figure 5) Re-install end pipe cover and screws.

CONNECTING POWER VENTER TO APPLIANCE

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.
