WARNING

CONDENSATE ALSO DRAINS FROM TWO LOCATIONS ON
THE BLOWER ASSEMBLY AS SHOWN IN FIGURE 5. A
CONDENSATE HOSE MUST BE SECURED TO FORM A "TRAP"
AS SHOWN IN FIGURE 5 FOR THESE CONDENSATE DRAIN
CONNECTIONS. THESE TWO HOSES MAY BE CONNECTED
TOGETHER. THE HOSE(S) SHOULD BE ROUTED TO A
SUITABLE DRAIN.

 A fitting that may be used to join the two hoses

from the blower assembly is included in a supplied kit.

FIGURE 5

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 110-120 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 a unit only where local codes permit.
If local codes do not permit use of flexible power supply cord:

A. Make sure the unit is unplugged  from the wall outlet.

Remove the plastic top cap. Remove screws and open
panel on the front of the control box on the blower.

B. Cut the flexible power cord, leaving enough to be able to make

connections. Remove the strain relief fitting from the box.

C. Install a suitable conduit fitting inside the enclosure.

D. Splice field wiring into existing wiring using code authorized

method (wire nuts, etc).

E. Be certain that neutral and line connections are not

reversed when making these connections.

F.

Ground heater properly.  This water heater must be grounded
in accordance with the National Electrical Code NFPA 70
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.

G. Close the panel on the control box. Make sure that the

access panel is secured shut.

5. The blower discharge boot is made to accept only straight sections

of 2" 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.

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 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 larger than the
marked circle.

B)  WOODEN SIDE WALLS
Drill a pilot  hole approximately one quarter inch outside of the
marked circle. This pilot hole is used as a starting point for a
saws-all or sabre saw blade. Cut around the marked circle
staying approximately one quarter inch outside of the line. (This
will allow the vent to easily slide through the opening.  The
resulting gap will be covered up by the Vent Terminal cover
plate.) Repeat this step on inside wall if necessary.

SEQUENCE OF INSTALLATIONS, FIGURE 6

Cut a length of PVC pipe about 3.5 inches 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 6.
