8)Slide the decorative wall thimble up to the wall surface being careful not to scratch the paint and attach with screws provided. Apply decorative brass or chrome trim if desired. See diagram 7.

3)To install the Round Support Box/WallThim- ble in a fl at 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 important to support the flue pipe every 3 feet, to avoidexcessivestressontheelbows, and possible separation. Wall straps are available for this purpose. See diagram 7.
Galvanized pipe and elbows may be utilized in the attic as well as above the roofl ine. The galvanized fi nish is desirable above the roofl ine due to its higher corrosion resist- ance.
Continue to add pipe sections through the flashing until the height of the flue cap meets the minimum height requirements specifi ed in diagram 12 or local codes. Note that for steep roof pitches, the vertical height must be increased. Apoor draft, or down drafting can result from high wind conditions near big trees or adjoining roof lines, in these cases, increasing the fl ue height may solve the problem.
DURA-FLUE VERTICAL
TERMINATION
1)Maintain the
when passing through ceil- ings, walls, roofs, enclo- sures, attic rafter, or other nearby combustible surfaces. Do not pack air spaces with insulation. Check page 9 for the maximum vertical rise of the fl uing 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 fl ue exit, and mark the location where
the fl ue 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
spot where the fl ue will penetrate the roof. Determine if ceiling joists, roof rafters or other framing will obstruct the fluing system. You may wish to relocate the appliance 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
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 suffi cient size to meet the minimum requirements for clearance to combustibles of
