NoTE: If an offset is needed to avoid obstructions, you must support the vent pipe every three
(3) feet. use wall straps for this purpose. Refer to Page 23, Figure 30. whenever possible, use
45° elbows instead of 90° elbows. The 45° elbow offers less restriction to the flow of the flue
gases and intake air.

flashing. There must be a 1" clearance from the vent pipe to combustible materials.
6. Continue to add pipe sections until the height of the vent cap meets the minimum building code
requirements.
NoTE: you must increase vent height for steep roof pitches. Nearby trees, adjoining roof lines,
steep pitched roofs, and other similar factors may cause poor draft or down-drafting in high
winds. Increasing the vent height may solve this problem.
NoTE: If the vent pipe passes through any occupied areas above the first floor, including
storage spaces and closets, you must enclose pipe. you may frame and sheetrock the enclosure
with standard construction material. Make sure to meet the minimum allowable clearances to
combustibles. do not fill any of the required clearance spaces with insulation.
