When the vent termination exits through foundations less than 20” (508 mm) below siding outcrop, the vent pipe must be flush with the siding.
It is always best to locate the fireplace in such a way that minimizes the number of offsets and horizontal vent length of vent pipe from the flue collar of the fire- place to the face of the outer wall.
Horizontal plane means no vertical rise exists on this portion of the vent assembly.

•The maximum number of 90° elbows per side wall installation is three (3), but must not have two (2) consecutive elbows in the horizontal plane.
•A minimum of 2’ (610 mm) vertical section off the top of the unit is required, an elbow and a 1’ (305 mm) maximum horizontal run to get through a wall. (Fig. 16)
•The maximum number of 45° elbows permitted per side wall installation is two (2). These elbows can be installed in either the vertical or horizontal run. (Fig. 16)

•For each 45° elbow installed in the horizontal run, the length of the horizontal run MUST be reduced by 18” (45 cm). This does not apply if the 45° elbows are installed on the vertical part of the vent system.
to first position the fireplace and measure to obtain hole location. Depending on whether the wall is combustible or noncombustible, cut opening to size. (Fig. 19)
For combustible walls first frame in opening.
Combustible Walls: Cut a 16¹⁄₄”H x 16¹⁄₄” W (413 x 413 mm) hole through the exterior wall and frame as shown.
Noncombustible Walls: Hole opening must be 11¹⁄₄” (286 mm) in diameter.
