Offset Elbow Assembly

Offset elbows install the same as chimney sections. First, snap the inner section INTO the preceding inner section of flue. Check connec- tion by pulling up slightly to ensure a tight fit. Next, the outer sections snap lock OVER the preceding outer section of chimney. Again, check outer section by pulling up slightly to ensure proper connection is made.

Return Elbow Assembly

Return elbows install the same way as round terminations and stabilizers:

Step 1. Hold return elbow over top of last chimney section.

Step 2. Center inner slip section into inner flue pipe-slip down.

Step 3. Center outer-locking section over outer chimney pipe. Push down until locking joint has firmly engaged.

Step 4. Pull up slightly on return elbow to ensure locking joint has firmly engaged.

Step 5. Secure support straps to framing members by nailing under tension in sheer (Figure 40 ).

Note: The return elbow assembly performs the same function as a stabilizer. Consider this when determining the need for a stabilizer.

Note: Do not apply excessive pressure to any subsequent chimney section following return elbow assembly when installing. Ensure that each subsequent chimney section is securely attached by testing as noted above.

Combustion Air Kits

The installation of an outside combustion air kit is highly recommended. It is very impor- tant to ensure good fireplace operation in homes which are tightly weather sealed or have ventilating appliances installed.

Step 1. Determine the source for outside air, which can be installed through an outside wall or into a ventilated crawl space. In either case, a 4 1/2" diameter hole will be required for installation of the air inlet assembly.

CAUTION: AVOID INSTALLING THE AIR IN- LET WHERE THE OPENING COULD BE BLOCKED BY SNOW, BUSHES OR OTHER OBSTACLES. THE MAXIMUM HEIGHT FOR THE OUTSIDE AIR IS 50 FEET ABOVE THE HEARTH, PROVING THE AIR INLET IS TERMI- NATED A MINIMUM OF THREE (3) FEET BE- LOW THE CHIMNEY CAP LEVEL.

Note: Combustion air inlet ducts must not terminate in attic space.

Step 2. Install the air inlet eyebrow (FOAK-4 or FOAK-4LD) through the wall opening (Figure 41). Push a 4 inch diameter NON-COMBUSTIBLE Class 0 or Class I flexible duct onto the eyebrow.

Step 3. The air inlet for the outside air kit is located on the right hand side of the fireplace (Figure 42 ). Refer to the installation instruc- tions packed with each FOAK-4 air kit for specific installation information. The outside air kit, if used, must be installed before the fireplace is totally framed and enclosed within the finished walls.

After completing the installation of the optional combustion air vent system, the actuator arm must be put in service and tested to ensure proper operation before completing any enclo- sure around the firebox. Failure to do so may result in extensive and costly rework.

To operate, locate the hand operated shut-off lever at the lower right side of the fireplace opening behind the screen. To open the air damper, turn upwards. To close, turn down.

Operate the actuator through several cycles. Ensuring proper operation and freedom of movement. Return the actuator arm to the closed position.
