INSTALLING VENT SYSTEM INTO
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 instruc
-
tions are not substitutes for the
requirements 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 clearance
between vent pipes and combustible materials
such as insulation is 1".
CHECKING VENT CAPACITY
Complete all gas piping, electrical, and vent
connections. After adjusting the burner system
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. Improper venting, indicated
by escape or spillage of burned gas, will cause
match to flicker or go out. Smoke from a ciga
-
rette will also be pulled into the draft hood if the
vent is drawing properly.
