NOTE:

FLUE OUTLET SHOULD BE TWO FEET ABOVE ALL PORTIONS OF THE BUILDING

WITHIN TEN FEET AS SHOWN IN THE ILLUSTRATION. THE CHIMNEY MUST NOT

EXTEND MORE THAN 90 INCHES ABOVE THE ROOF WITHOUT ADDITIONAL SUPPORT.

1.Lay out, cut and frame openings through all ceilings and the roof at the point where the chimney will pass through. Unless the chimney is to be offset, the point where the center line of the chimney will pass through the ceiling and roof can be determined with a plumb line as shown by Figure 15. The fireplace should be located in the planned installation position. After the center line is established and a nail is driven to mark the point, the opening can be cut if you are satisfied with the chimney location relative to ceiling and roof joists and/or any other obstructions. The roof opening center line should be marked by driving a nail through the roof from underneath that will penetrate the roof and can be located from the rooftop. If the chimney is to penetrate a pitched roof, the hole in the roof must be rectangular instead of square and should be sized according to Table1.

2.Install the firestop spacer as required from beneath the ceiling unless the space above is attic space. In an attic, the firestop spacer should be installed at the floor level of the attic. You must have joists or headers on all four sides of the spacer and use a minimum of four 8-penney nails to secure the spacer.

3.To install the “L” series chimney sections, insert the male end of the flue, the smallest diameter pipe, into the flue outlet of the fireplace and press down until the snap locks engage. Continue the process, adding the chimney sections on top of each other until the chimney is at least six inches above the roof opening on all sided. As the chimney sections are installed, check each joint to make sure it is properly locked to the previous section. If additional strength of the outer pipe joints is desired, you may use two or three sheet metal screws placed through the area where the outer pipes overlap one another. To install these screws, drill a 1/8-inch diameter hole through the chimney sections, taking care not to penetrate the inner flue pipe. Warning: Be very careful when drilling the holes into the outer pipe. The drill must not penetrate the inner stainless steel pipe.

NOTE: If you intend to have a total fireplace installation of more that 30 feet you must use chimney support model LCS at or below 30 feet to support the weight of additional chimney pipe.

To install the chimney support, place the crimped end of the flue and outlet air duct portions into the last section of chimney pipe. Push down until the outside or inlet air duct of the chimney support overlaps and snap locks the chimney support into the chimney section.

Nail the support straps tightly to a building frame member or ceiling joist as shown by Figure 18. You must use at least two 8-penney nails per strap.
