For models HS115-4 & HS115-5 use BLACK and WHITE wires from electrical box wip and connect to proper terminals on motor. Upon first startup, as viewed from opposite end of shaft, verify HS115-4 & HS115-5 motors rotate clockwise. Mount electrical box with Fan Prover in a vertical position. [. . . ] It is recommended that the Power Venter be mounted as close as possible to the point of termination. HS-3 HS-4, HS-5 VENT PIPE INSTALLATION If Installing the Power Venter on an appliance not equipped with a draft hood or draft diverter (e. g. Power Burners, Induced Draft), a barometric draft control must be added. The barometric draft control must be the same size as the flue outlet and installed as close as possible to the appliance. After the draft hood, draft diverter or barometric draft control, a tapered reducer should be installed to reduce the flue to the size shown in the selection table on page 2 of these instructions. After the tapered reducer, install the appropriate type of vent pipe to the inlet of the Power Venter. The vent pipe chosen must be in compliance with local codes. The Power Venter inlet and outlet are designed to accept single wall vent pipe. If using vent pipe other than single wall, the installer must supply adapters to connect to the Power Venter. ELECTRICAL SPECIFICATIONS 5 MODEL HS-3, HS-4, HS-5 WIRING WITH SINGLE APPLIANCE The HS-3, HS-4, and HS-5 Power Venters are equipped with 2 relays. One is used to activate the Power Venter while the other is used to isolate the Fan Proving Switch from the load of the appliance. The relays and Fan Proving Switch are factory wired for easy installation. The installer needs to complete 3 steps to wire the Power Venter as noted below: 1. Route the metal conduit from the electrical box to the Power Venter motor and connect the Black, White and Ground wires to the motor. Connect the Red, Blue and Orange wires in the electrical box to the appliance. Supply 115 VAC to the input wires in the electrical box. NOTE: All models as viewed from the opposite end of the shaft should rotate clockwise. The motor should be wired correctly by Tjernlund for proper rotation.

[. . . ] will issue credit to the original distributor or provide a free part to replace one that becomes defective during the one year warranty period. If the part is over 18 months old, proof of date of the installation in the form of the contractor sales/installation receipt is necessary to prove the unit has been in service for under one year. All receipts should include the date code of the Power Venter to ensure that the defective component corresponds with the complete unit. This will help preclude possible credit refusal. [. . . ]
