[. . . ] With an input over 50, 000 BTU's per hour, a 12" termination clearance shall be required. The vent termination point shall not be installed closer than 3' from an inside corner of an L-shaped structure. The vent termination should not be mounted directly above, or within 3' horizontally from an oil tank vent or gas meter. The bottom of the vent terminal shall be located at least 12" above finished grade. Page 4 Diagram A 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. Wood or vinyl siding should be cut so that the unit mounts directly on the wall board to provide a stable support. Check ground circuit to make certain that the unit has been properly grounded. The wiring should be protected by an over-current circuit device rated at 15 amperes. CAUTION MUST be taken to ensure that the wiring does not come in contact with any heat source. All line voltage and safety control circuits, between the power venter and the appliance, MUST be wired in accordance with the National Electrical Code for Class 1 wiring or equivalent. AIR FLOW ADJUSTMENTS In order to obtain proper system draft, the power venter has an airflow adjustment damper built in. When used in a system with a barometric draft control, this damper should be used to make coarse draft adjustments while the barometric should be used for finer adjustments. Loosen the locking screw on the air flow adjustment damper on the outer pipe of the power venter. (See Figure 8) Adjust the damper to the full open position. Follow appliance manufacturer's procedures for starting the heating appliance. Then adjust the thermostat to call for "Heat". After the system has operated for several minutes to stabilize flue gas temperatures, check for negative draft or up-draft at the heating appliance outlet or air flow into the draft hood. [. . . ] Rotate the motor assembly counter-clockwise and slide the assembly into the center. Then pull the motor assembly out of the unit. Clean off any build-up inside the blower wheel housing and the blower wheel. CAUTION: Avoid applying excess pressure on the blower wheel when cleaning off any build-up of material. [. . . ]
