Figures 22 through 24 show other options for the gas vent. When
venting through a side wall your vent pipe must have the proper
temperature rating (see Figure 24). Manufacturer's clearances must
also be maintained. Consult the authority having jurisdiction in your
area regarding venting through side wall.

INSTALLING VENT SYSTEM IN A CHASE
A chase is a vertical box-like structure built to enclose venting that runs
along the outside of a building. A chase is not required for such venting.
NOTICE: Treatment of firestops and construction of
the chase may vary from building type to building
type. These instructions are not substitutes for the
requirements of local building codes. You must fol-
low all local building codes.
Note: When installing in a chase, you should insulate the chase as
you would the outside walls of your home. This is especially
important in cold climates. Minimum clearance between vent pipes
and combustible materials such as insulation is 1".
