3.Make sure that plastic tubing is still attached to the pressure switch and fan housing. Also make sure that wiring connector from motor to control box is securely attached.

4.Do not plug in power cord until vent system is completely installed. The Power Vent operates on 120 Vac, therefore a grounded outlet must be within reach of the 6 foot flexible power cord supplied with the vent (see fig.1). The power cord supplied may be used on unit only where local codes permit. If local codes do not permit use of flexible power supply cord:

A.Remove screws that hold cover plate on control box and remove plate.

B.Cut flexible power cord on inside of control box, as close to inside wall as possible.

C.If flexible cord and strain relief are removed, then opening in box must be covered by a plastic cap on the front side of the control box.

D.Remove plastic cap on the right side of control box and install suitable conduit fitting in enclosure.

E.Splice field wiring into existing wiring using code authorized method (wire nuts, etc).

F.Be certain that neutral and line connections are not reversed when making these connections.

G.Ground heater properly. This water heater must be grounded in accordance with the National Electric Code ANSI/NFPA70 and/or local codes. These must be followed in all cases.

The water heater must be connected to a grounded metal, permanent wiring system; or an equipment grounding conductor must be run with the circuit conductors and connected to the equipment grounding terminal or lead on the water heater, see Figure 7.

H.Replace cover plate and secure with two screws.

5.The blower discharge boot is made to accept only straight sections of 3" pipe. To start off with an elbow, a short section of the furnished pipe, a minimum of 2 inches, must be cut and glued into the end of the elbow that will mount on the discharge boot (see fig. 6).
