INSTALLATION PLANNING

There are two basic types of direct-vent installations:

Horizontal Termination

Vertical Termination

Horizontal Termination Installation

IMPORTANT: Horizontal square terminations require only inner portion of wall firestop. Horizontal installation using round termina- tion require exterior portion of wall firestop (see Figure 18, page 11).

1. Set the fireplace in its desired location and determine the route

your horizontal venting will take. Do not secure the fireplace

until all venting has been installed. Some installations require

sliding the fireplace in and out of position to make final venting

connections.Figures19through25onpages11through13show

different configurations for venting with horizontal termina-

tion that will help you decide which application best suits your

installation. Check to see if wall studs or roof rafters are in the

path of your desired venting route. If they are, you may want

to adjust the location of the fireplace.

2. Direct vent pipe sections and components are designed with

special twist-lock connections.

Twist-Lock Procedure: The female ends of the pipes have

locking lugs (indentations). These lugs will slide straight into

one-quarter turn until the sections are fully locked (see Figure

feet. Use wall strap for this purpose.

3. Any straight pipe section, a 45°, or a 90° elbow can be used

whenfirstconnectingtheventingsystemtothefireplace.Elbows

are designed to twist lock into any of four 90° positions to direct

the venting system to the desired location.

IMPORTANT: Do not attempt to alter the configuration of the

elbows by cutting, twisting, bending, etc.

4. Assemble the desired combination of pipe and elbows to the

fireplace flue collar. If there are long portions of venting run,

pipe sections may be pre-assembled and installed for convenience.

5. Carefully determine the location where the vent pipe assembly

will penetrate the outside wall. The center of the hole should line

up with the center-line of the horizontal vent pipe. Mark the wall

for a 10 ¾” x10 ¾” square hole. Cut and frame the square hole

in the exterior wall where the vent will be terminated. If the wall

being penetrated is constructed of noncombustible material, such

as masonry block of concrete , a 8 ½” hole with zero clearance is

acceptable (see Figure 12).

WARNING: Do not recess vent termination into any wall. This will cause a fire hazard.

WARNING: Never run vent downward as this may cause excessive temperatures which could cause a fire. Operation of improperly installed and main- tained venting system could result in serious injury, property damage or loss of life.
