Lucent Technologies TM-4500 Installing Offsets, Offset Elbow Assembly, Or Ceiling

INSTALLING OFFSETS

First, review the Offset Elevation Chart and Figure 40 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

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.

CHIMNEY 30° OFFSET THROUGH FLOOR

OR CEILING

It may be necessary to assemble the chimney at 30° when passing through the floor or ceiling area. Use the F10FS30-2 firestop spacer as shown in Figures 42 and 43. Support the chimney at floor or ceiling penetration with a FTF10 stabilizer if distance of chimney below ceiling is 10' or more. Maintain 2" minimum air space to combustibles from chimney sections.

CONSIDERATIONS

Combustion Air Kits

Use combustion air kit, Model FOAK-4 or Model FOAK-4LD, with the Colonial Series fireplaces. Refer to installation instructions packed with the air kit for specific installation information. The outside air kit must be installed before the fireplace is framed and enclosed in the fin- ished walls.

Outside air drawn into the fireplace supplies air to the fire for combustion. Only one combus- tion air duct on the left side of the fireplace is necessary if installed (Figure 44 ).

If additional length of duct is necessary, pur- chase locally available U.L. Class 0 or Class 1 metallic duct. The duct may extend up to 50'

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.

(15.24 m) in any direction.

Note: When installing the air duct vertically, DO NOT terminate the duct closer than 3' (914mm) below the chimney top.

There is a one-hand operated shut-off valve located in the left side of the fireplace opening behind the screen. To open, rotate handle up- wards. The handle should lock open at 45° .

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 fastening under tension in sheer (Figure 41 ).

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

The combustion air damper should be fully open when the fireplace is in use and fully closed when the fireplace is not in operation to prevent outside air from entering your home.

CAUTION: NEVER LOCATE INLET WHERE IT CAN BE BLOCKED BY SHRUBS, SNOW DRIFTS, ETC. NEVER LOCATE INLET IN GA- RAGE OR ANY AREA WHERE THERE IS AN- OTHER FUEL-BURNING APPLIANCE OR PRODUCTS EMITTING COMBUSTIBLE GASES SUCH AS PAINT, GASOLINE, ETC. IN COLD CLIMATES IT IS RECOMMENDED THE COM- BUSTION AIR DUCT BE INSULATED.
