INSTALLATION

7)Install the Wall Thimble in the center of the 10" square and attach with wood screws.
8)Slide the decorative wall thimble up to the wall surface being careful not to scratch the paint and attach with screws provid- ed. Apply decorative brass or chrome trim if desired. See diagram 7.

3)To install the Round Support Box/Wall Thim- ble in a flat ceiling, cut a 10 inch square hole in the ceiling centred on the hole drilled in Step 2. Frame the hole as shown in diagram 10.
6)Continue to assemble pipe lengths.
Note: If an offset is necessary in the attic to avoid obstructions, it is impor- tant to support the flue pipe every 3 feet, to avoid excessive stress on the elbows, and possible sep- aration. Wall straps are available for this purpose. See diagram 7.
Galvanized pipe and elbows may be uti- lized in the attic as well as above the roofline. The galvanized finish is desirable above the roofline due to its higher corro- sion resistance.
Continue to add pipe sections through the flashing until the height of the flue cap meets the minimum height requirements specified in diagram 12 or local codes. Note that for steep roof pitches, the vertical height must be increased. A poor draft, or down drafting can result from high wind conditions near big trees or adjoining roof lines, in these cases, increasing the flue height may solve the problem.

1)Maintain the
combustibles when pass- ing through ceilings, walls, roofs, enclosures, attic rafter, or other nearby combustible surfaces. Do not pack air spac- es with insulation. Check page 9 for the maximum ver- tical rise of the fluing system and the maximum horizontal offset limitations.
2)Set the gas appliance in its desired location. Drop a plumb bob down from the ceiling to the position of the
appliance flue exit, and mark the location where the flue will penetrate the
ceiling. Drill a small hole at
his point. Next, drop a plumb bob from the roof to
the hole previously drilled
in the ceiling, and mark the Diagram 8 spot where the flue will penetrate the roof. Determine if ceiling joists, roof rafters or other framing will obstruct the fluing sys- tem. You may wish to relocate the appli- ance or to offset, as shown in diagram 9 to avoid cutting load bearing members.
4)Assemble the desired lengths of black pipe and elbows necessary to reach from the appliance adaptor up though the Round Support Box. Insure that all pipes and elbow connections are in the fully twist- locked position and sealed.
5)Cut a hole in the roof centred on the small drilled hole placed in the roof in Step 2. The hole should be of sufficient size to meet the minimumrequirementsforclearancetocom- bustibles of
Diagram 11: The upper half of the flashing is installed under the roofing material and not nailed down until the chimney is installed.
This allows for small adjustments.
Roof Pitch | Minimum Flue Height | |
| Feet | Meters |
flat to 7/12 | 2 | 0.61 |
over 7/12 to 8/12 | 2 | 0.61 |
over 8/12 to 9/12 | 2 | 0.61 |
over 9/12 to 10/12 | 2.5 | 0.76 |
over 10/12 to 11/12 | 3.25 | 0.99 |
over 11/12 to 12/12 | 4 | 1.22 |
over 12/12 to 14/12 | 5 | 1.52 |
over 14/12 to 16/12 | 6 | 1.83 |
over 16/12 to 18/12 | 7 | 2.13 |
over 18/12 to 20/12 | 7.5 | 2.29 |
over 20/12 to 21/12 | 8 | 2.44 |
7)Ensure flue is vertical and secure the base of the flashing to the roof with roofing rails, slide storm collar over the pipe section and seal with a mastic.
8)Install the vertical termination cap by twist locking it.
