INSTALLATION

VERTICAL

TERMINATIONS

1) Maintain the 1-1/4" clearances (air spaces) to combustibles when passing through ceilings, walls, roofs, enclosures, attic rafter, or other nearby combustible surfaces. Do not pack air spaces with insulation. Check section "Simpson Dura- vent Flueing" for the maximum vertical rise of the fl ueing system and the maximum horizontal offset limitations.

2)Set the gas appliance in its desired location.

will obstruct the			fl ueing system. You

may wish to relocate the appliance or to offset,asshowninDiagram2toavoidcutting load bearing members.

Note: Apply sealant "Mill-Pac" to inner pipe and high temperature silicone sealant to outer pipe on every twist- lock joint.

3)A Firestop spacer must be installed in the

floor or ceiling of every level. To install the Firestop spacer in a fl at ceiling or wall, cut a 10 inch square hole. Frame the hole

as shown in Diagram 3 and install the fi restop.

4)Assemble the desired lengths of pipe and elbows. Ensure that all pipes and elbow connections are in the fully twist-locked position and sealed.

5)Cut a hole in the roof centered 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 1-1/2". Slip the fl ashing under the shingles (shingles should overlap half the fl ashing) as per Diagram 4.

Diagram 4: The upper half of the fl ashing is installed under the roofi ng material and not nailed down until the chimney is installed.

This allows for small adjustments.

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 avoid excessive stress on the elbows, and possible separation. Wall straps are available for this purpose (Diagram 2).

Galvanizedpipeisdesirableabovetheroofline duetoitshighercorrosionresistance.Continue to add pipe sections through the flashing until the height of the flue cap meets the minimum height requirements specified in Diagram 5 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.

7)Ensure fl ue is vertical and secure the base of the fl ashing to the roof with roofi ng rails, slide storm collar over the pipe section and seal with a mastic.

8)Install the vertical termination cap by twist- locking it.

Note: Any closets or storage spaces, which the flue passes through must be enclosed.
