Constructing the Fireplace Chase
A chase is a vertical box-like structure built to enclose the
gasfireplace and/orits ventsystem. Vertical ventsthat run
on the outside of a building may be, but are not required to
be, installed inside a chase.
CAUTION: TREATMENT OF FIRESTOP SPACERS AND

BUILDINGCODES. THEREFORE,YOURLOCAL BUILD-
ING CODES MUST BE CHECKED TO DETERMINE THE
REQUIREMENTSFOR THESESTEPS.
Factory-builtfireplace chasesshouldbeconstructed in the
manner of all outside walls of the home to prevent cold air

Starting Collars
To attach the first vent component to the starting collars of
thefireplace:
• Make sure that the fiberglass gasket supplied in the
manual bag seals between the first 8 inch (203mm)
vent component and the outer fireplace wrap. Using 2
self-tapping screws from the manual bag secure that
gasket to the outer wrap (see Figure 18).

To Install the Heat Shield:
1. Determine if the heat shield is required. Do so by mea-
suring the vertical distance between the top horizontal
surfaceofthe elbowto anycombustible surfaceabove.
If the distance is more than 4 inches, the heat shield is
NOT required. If it is 4 inches or less, the heat shield IS
REQUIRED.Installperthefollowingsteps.SeeFigure19.

5. Install Firestops
For Horizontal Runs - Firestops are REQUIRED on both
sidesof acombustible wallthrough whichthevent passes.
NOTE: Model DVP-TRAP does not need an exterior
firestop on an exterior combustible wall.
To install firestops for horizontal runs that pass through
eitherinterioror exteriorwalls:
• Cuta 10-inchby12-inch (254mmx 305mm)holethrough
the wall.
NOTE: The center of the hole is one (1) inch (25.4mm)
above the center of the horizontal vent pipe.
• Position the firestops on both sides of the hole previ-
ously cut and secure the firestops with nails or screws.
• The heat shields of the firestops MUST BE placed to-
wards the top of the hole.
• Continuethe ventrun throughthe firestops.
