DIRECT VENT TERMINAL INSTALLATION

The air intake provided on the unit contains an air intake screen to

prevent large particles from entering the unit.

Figure 13: AIR INTAKE SCREEN

When the unit is to be setup as a direct vent, the air intake screen

must be removed. The air intake pipe may then be glued to the air

intake (see Figure 13) provided on the unit.

This unit consists of two terminals - an air intake terminal and an

exhaust vent terminal. The air intake terminal is a 2” 90° pvc elbow

with an air intake screen and the exhaust vent terminal is a 2” straight

pvc coupling with a mesh wire screen.

Note: to prevent exhausting products from circulating to the air intake

in windy/cold areas, the maximum practical distance between these

two terminals is recommended.

INSTALLATION SEQUENCE

1. After the points of termination have been determined,

use the cover plates as templates to mark the holes for

the vent pipes to be inserted through the wall. BEWARE OF

CONCEALED WIRING AND PIPING INSIDE OF WALL. If the

vent terminals are being installed on the outside of a finished

wall, it may be easier to mark both the inside and outside

wall. Align the holesby 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 holes

as a centering point for the template.

A.) MASONRY SIDE WALLS Chisel an opening approximately

1/2” (1.3 cm) 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 pipe to easily slide through

the opening. The resulting gap will be covered by the

vent terminal cover plates.) Repeat this step on the

inside wall if necessary.

2. Cut a length of pipe about 3.5” (8.9 cm) longer than the

wall thickness at the opening.

3. Glue the air intake terminal to the section of the pipe.

4. Slide the wall plate over pipe to stop against air intake terminal.

5. Place a bead of caulking (not supplied) around the gap between

the pipe and the wall. Place some of the caulking on the

back of the plate to hold it against the wall after installation.

6. If the air intake pipe is installed up to the wall, with a coupling on the

end against the wall opening, the pipe with the air intake terminal can

be prepared for gluing before inserting through the wall. Slide the

pipe through the wall and insert into coupling on the other side of

the wall, making sure that the air intake terminal ends up pointed in the

correct position (Figure 13A and Figure 14).
