INSTALLING OFFSETS

First, review the Offset Elevation Chart and Figure 34 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 ceiling, first determine the center point for a vertical chimney following the instructions for vertical 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 In- stallation Instructions for cutting and framing ceiling 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.

Step 5. Secure support straps to framing members by nailing under tension in sheer (Figure 35).

Notes:

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

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 Kit

A Blower Kit model BFK36 is preinstalled, standard, on model BCD36MH and is available as an option for model BC36MH. The optional Blower Kit can be installed prior to or after installation of the fireplace.

Note: These fireplace models are not supplied with an optional wall switch (FWSK) for fan operation. BFK36 blower kits may be operated with their integral blower (On/Off) switch.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

IMPORTANT

The fireplace must be wired to the house electrical system at the time of installation in order for the fans to operate, (See Figures 36 and 37).

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

IMPORTANT

This fireplace is not intended to be used as a substitute for a furnace to heat an entire home. Use for supplementary heating only.

The BFK36 Blower Kit is design certified by War- nock Hersey for use with these appliances.
