INSTALLING OFFSETS

First, review the Offset Elevation Chart and Figure 38 for reference.

Step 1. Determine the offset distance where chimney is to pass through the first ceiling- dimension “A.” To find this point on your ceil- ing, first determine the center point for a verti- cal chimney following the instructions for ver- tical installation.

Measure height to the ceiling from the top of fireplace-dimension “B.” Use the appropriate Offset Elevation Chart to find dimension “A.” Mark point where you will drive your nail to show the center point for your offset ceiling cut.

Step 2. Proceed by using the Straight Up Instal- lation Instructions for cutting and framing ceil- ing and roof openings.

Note: See Framing and Dimension Chart for the sizes of the ceiling and roof openings. The size of the roof opening varies with the degree of pitch of the roof.

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.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Step 5. Secure support straps to framing members by nailing under tension in sheer (Figure 41 ).

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.

OPTIONAL EQUIPMENT

CONSIDERATIONS

Blower Kits (Circulating Models Only)

Blower Kits model FBK-100/200 are available for use with circulating models. The Blower Kit can be installed prior to or after installation of the fireplace.

Note: These fireplace models require a wall switch for fan operation. Refer to the installa- tion instructions included with the Blower Kits for installation details.

THE FIREPLACE MUST BE WIRED TO THE HOUSE ELECTRICAL SYSTEM AT THE TIME OF INSTALLATION IN ORDER FOR THE OP- TIONAL FANS TO OPERATE, (SEE FIGURES 42 AND 43 ).

Note: The utilization of fans will increase the air flow around the firebox. However, only a minimal increase in heat output should be anticipated.
