Installing the Fireplace
Step 1. Locating the Fireplace
The following diagram shows space and clearance require-
ments for locating a fireplace within a room.

* See Figure 3.
** The clearance to the ceiling is measured from the top
of the unit, excluding the standoffs (see Figure 38).
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.
For minimum clearances, see the direct vent termination
clearance diagrams on pages 24 and 25 in this manual.

Clearance Requirements
The top, back, and sides of the fireplace are defined by
stand-offs. The minimum clearance to a perpendicular wall
extending past the face of the fireplace is one inch (25 mm).
The back of the fireplace may be recessed 21 1/2 inches
(546 mm) into combustible construction.
Constructing the Fireplace Chase
A chase is a vertical box-like structure built to enclose the
gas fireplace 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 fireplace 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 floor of the chase should be insulated. Vapor and air
infiltration barriers should be installed in the chase as per
regional codes for the rest of the home. Additionally, in re-
gions where cold air infiltration may be an issue, the inside
surfaces may be sheetrocked and taped for maximum air
tightness.
To further prevent drafts, the wall shield and ceiling firestops
should be caulked with high temperature caulk to seal gaps.
Gas line holes and other openings should be caulked with
high temp caulk or stuffed with unfaced insulation. If the
appliance is being installed on a cement slab, a layer of
plywood may be placed underneath to prevent conducting
cold up into the room.
THE CHASE SHOULD BE CONSTRUCTED SO THAT ALL
CLEARANCES TO THE FIREPLACE ARE MAINTAINED
AS SPECIFIED WITHIN THIS INSTALLERS GUIDE.
*If venting with (2) 90

elbows off rear of unit
the dimensions C, D, and E, will change.
