INSTALLATION OF LISTED
B-1 VENT
Figures 24, 25 and 26, show other options
for the gas vent. When venting through a
side wall your vent pipe must have the
proper temperature rating (see Figure 26).
Manufacturer’s clearances must also be
maintained. Consult the authority having
jurisdiction in your area regarding venting
through side wall.

CHECKING VENT CAPACITY
Complete all gas piping, electrical, and vent
connections. After adjusting the fireplace
and lighting the main burners, allow a couple
of minutes for warm-up. Hold a lighted
match just under the rim of the draft hood
relief opening. Proper venting will draw the
flame toward or into the draft hood. Im-
proper venting, indicated by escape or spill-
age of burned gas, will cause match to
flicker or go out. Smoke from a cigarette
will also be pulled into the draft hood if the
vent is drawing properly.

INSTALLING VENT SYSTEM
IN A CHASE
A chase is a vertical boxlike structure built
to enclose venting that runs along the out-
side 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 re-
quirements of local building
codes. You must follow 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 im-
portant in cold climates. Minimum clear-
ance between vent pipes and combustible
materials such as insulation is 1".
