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. 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 Electrical 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 19.
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 figure 16).
INSTALLATION OF VENT SYSTEM
Before beginning installation of piping system thoroughly read the section of this manual VENT PIPE PREPARATION.
If you are installing your system so that it vents through the roof, please refer to section titled INSTALLATION OF VERTICAL VENT SYSTEM.
VENT TERMINAL INSTALLATION, SIDEWALL
1.Install the vent terminal by using the cover plate as a template to mark the hole for the vent pipe to pass through the wall. BEWARE OF CONCEALED WIRING AND PIPING INSIDE THE WALL.
2.If the Vent Terminal is being installed on the outside of a finished wall, it may be easier to mark both the inside and outside wall. Align the holes by drilling a hole through the center of the template from the inside through to the outside. The template can now be positioned on the outside wall using the drilled hole as a centering point for the template.
3.A) MASONRY SIDE WALLS
Chisel an opening approximately one half inch (1.3 cm) larger than the marked circle.
B) WOODEN SIDE WALLS
Drill a pilot hole approximately one quarter inch (0.64 cm) outside of the marked circle. This pilot hole is used as a starting point for a
SEQUENCE OF INSTALLATIONS, FIGURE 17
Cut a length of PVC pipe about 3.5 inches (8.9 cm) longer than the wall thickness at the opening. Glue the vent terminal to this section of pipe. Slide the wall plate over the pipe to stop against the vent terminal. Place a bead of caulking (not supplied) around the gap between the pipe and cover plate. Apply enough to fill some of the gap between the pipe and wall. Place some of the caulking on the back of the plate to hold it against the wall after installation. If the vent pipe is installed up to the wall, with a coupling on the end against the wall opening, the pipe with the vent terminal can be prepared for gluing before inserting through the wall. Slide the pipe through the wall and insert into the coupling on the other side of the wall, making sure that the vent terminal ends up pointed in the correct position, see Figure 17.
