Installing the Fireplace
Constructing the Fireplace Chase
A chase is a vertical box-like structure built to enclose the
gas fi replace and/or its vent system. Vertical vents that 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
CONSTRUCTION OF THE CHASE MAY VARY WITH THE
TYPE OF BUILDING. THESE INSTRUCTIONS ARE NOT
SUBSTITUTES FOR THE REQUIREMENTS OF LOCAL
BUILDING CODES. THEREFORE, YOUR LOCAL BUILD-
ING CODES MUST BE CHECKED TO DETERMINE THE
REQUIREMENTS FOR THESE STEPS.
Factory-built fi replace chases should be constructed in the
manner of all outside walls of the home to prevent cold air
drafting problems. The chase should not break the outside
building envelope in any manner.
This means that the walls, ceiling, base plate and cantile-
ver fl oor of the chase should be insulated. Vapor and air
infi ltration barriers should be installed in the chase as per
regional codes for the rest of the home. Additionally, we
recommend that the inside surfaces be sheetrocked and
taped for maximum air tightness.
To further prevent drafts, the fi restops should be caulked
to seal gaps. Gas line holes and other openings should
be caulked or stuffed with insulation. If the unit is being
installed on a cement slab, we recommend that a layer of
plywood be placed underneath to prevent conducting cold
up into the room.
THE CHASE SHOULD BE CONSTRUCTED SO THAT
ALL CLEARANCES TO THE FIREPLACE ARE MAIN-
TAINED AS SPECIFIED WITHIN THIS INSTALLERS
GUIDE.
Step 1. Locating the Fireplace
The following diagram shows space and clearance require-
ments for locating a fi replace within a room.
Clearance Requirements
The top, back, and sides of the fi replace are defi ned by
stand-offs. The minimum clearance to a perpendicular wall
extending past the face of the fi replace is one inch (25 mm).
The back of the fi replace may be recessed 21 1/2 inches
(546 mm) into combustible construction.

** The clearance to the ceiling is measured from the top
of the unit, excluding the standoffs (see Figure 36).
The distance from the unit to combustible construction
is to be measured from the unit outer wrap surface to
the combustible construction, NOT from the screw
heads that secure the unit together.
