Installing the Fireplace
Step 1. Locating the Fireplace
Space and clearance requirements for locating a fireplace
within a room (see Figure 3).
Minimum Clearances

Glass Front ...................................... 36 ........ 914
Floor .................................................. 0 ........... 0
Rear ................................................ 1/2 ........ 13

Top (QV32) .................................. 1 1/2 ....... 38
(QV36) .................................. 3 1/4 ....... 83
Ceiling* ............................................. 31 ........ 787
For minimum clearances, see the direct vent termination
clearance diagrams in Figures 30 and 31 in this manual.
Minimum Clearances

At Wall Firestops
Top .................................. 2 1/2 ............ 63.7
Bottom .............................. 1/2 ............... 13
Sides .................................. 1 ................ 25
* 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.

Clearance Requirements
The top and back of the fireplace are defined by stand-
offs. The minimum clearance to a perpendicular wall
extending past the face of the fireplace is 3 inches (76mm).
The back of the fireplace may be recessed 16 1/4 inches
(413mm) into combustible construction.

and Space Requirements
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 out-
side 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, Alad-
din Hearth Products recommends that the inside surfaces
be sheetrocked and taped for maximum air tightness.
To further prevent drafts, the firestops should be caulked
to seal gaps. Gas line holes and other openings should be
caulked or stuffed with insulation. If the unit is being in-
stalled on a cement slab, we recommend that a layer of
plywood be placed underneath to prevent conducting cold
up into the room. Be sure to include spark arrestors for
woodburning units if they are required.
THE CHASE SHOULD BE CONSTRUCTED SO THAT
ALL CLEARANCES TO THE FIREPLACE ARE MAIN-
TAINED AS SPECIFIED WITHIN THIS INSTALLERS
GUIDE.
