Sidewall Applications
Since it is very important that the vent- ing system maintain its balance between the combustion air intake and the flue gas exhaust, certain limitations as to vent configurations apply and must be strictly adhered to.
The vent graph showing the relationship between verti- cal and horizontal side wall venting will help to deter- mine the various dimensions allowable.

18” (45 cm). This does not apply if the 45° elbows are installed on the vertical part of the vent system. For each 90° elbow installed in the horizontal run, the length of the horizontal run MUST be reduced by 36” (914 mm).
•The maximum number of elbow degrees in a system is 270°. (Fig. 18)

When the vent termination exits through foundations less than 20” (508mm) 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’ (610mm) vertical section off the top of the unit is required, an elbow and a 1’ (305mm) 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
