hearth products be installed and
serviced by professionals who
are certified in the United States
by NFI (National Fireplace
Institute®).
Do not put
furniture or other objects
in this space in front of
the replace:
36” (0.9 m)
Fireplace
Hearth
CAUTION—HOT! HOT! HOT!
This appliance is a HEATING appliance and it
becomes very hot when in operation.
UNDER ANY CIRCUMSTANCES, DO NOT
PLACE any object, furniture, draperies or
other item LESS THAN 36 inches (0.9 m) IN
FRONT OF THE FIREPLACE.
CHILDREN and PETS
Radiant heat heats surfaces such as the
glass and hearth in front of the fireplace
to temperatures that, although approved
safe, are still dangerous to touch and
uncomfortable too step on. Young children
and pets must always be supervised when
in the room where the appliance is located.
The remote control handset should be kept
out of reach of children. To ensure safety,
we STRONGLY RECOMMEND that you install
in front of the fireplace: a fire screen or, to
protect young toddlers, a hearth gate—see Options on page 45.
HOT SURFACES
Be aware that, although safe, some combustible materials and finishes, even though
installed at listed clearances may, over time, discolor, warp or show cracks. The 1500
requires the installation of the cement board provided with the engine.
Convective heat will exit the unit and travel up the wall surface if not impeded. Protruding
mantels and projections can help direct the heat away from the wall. AVOID PLACING heat
sensitive items such as televisions, paintings, decorations, etc. above fireplaces or near the
edge of protrusions unless appropriate.

HOT SURFACES. Be aware that, although safe,
some combustible materials and finishes, even
though installed at listed clearances may, over time,
discolor, warp or show cracks. The 1500 requires the
installation of the cement board provided with the
engine.
Convective heat will exit the unit and travel up the
wall surface if not impeded. Protruding mantels and
projections can help direct the heat away from the
wall. AVOID PLACING heat sensitive items such
as televisions, paintings, decorations, etc. above
fireplaces or near the edge of protrusions unless
appropriate.
Radiant heat can heat surfaces such as the hearth in
front of the fireplace to temperatures that, although
approved safe, can be quite uncomfortable to
touch or step on—particularly for children and pets.
Accessory screens and guards will reduce the
radiant heat on these surfaces.
Important Safety Information
Operating Your Fireplace for the First
Time
When operating your new fireplace for the first time,
some vapors may be released due to the burning of
curing compounds used in the manufacture of the
appliance. They may cause a slight odor and could
cause the flames to be the full height of the firebox, or
even slightly higher, for the first few hours of operation.
It is also possible that these vapors could set off any
smoke detection alarms in the immediate vicinity.
These vapors are quite normal on new appliances. We
recommend opening a window to vent the room. After
a few hours use, the vapors will have disappeared and
the flames will be at their normal height.
State of California. Proposition 65
Warning.
Fuels used in gas, wood-burning or oil fired appliances,
and the products of combustion of such fuels, contain
chemicals known to the State of California to cause
cancer, birth defects and other reproductive harm.

Important Installer Notice –
Weather Sealing & Vapor Barriers
It is the installer’s responsibility to ensure that vent
installations through exterior walls are caulked and
weatherproofed in such a manner as to:
• Prevent rain water from entering the wall from
the weather side by adequately caulking the
outer vent plate to the exterior wall surface.
• Prevent moisture inside the home from
penetrating into the wall structure by ensuring
the inside wall plate is adequately sealed to the
inside vapor barrier.
• Prevent rain water and moisture from entering
the walls by sealing the joints between the outer
vent tube and the inner and outer wall plates.
We recommend the use of a high quality
polyurethane sealant.

How to Read the Venting Chart
The chart below applies to co-axial roof or wall
termination.
1. The total length of the vent pipe cannot exceed
40 feet.
2. The minimum vertical height with roof termination is
6 feet.
3. Any combination of rise and run can be used as
long as they are within the allowable limits shown
on the chart below.
4. A maximum of 4 x 90 degrees elbows—or
equivalent (2 x 45 degrees = 90 degrees)—can
be used. Excludes the 45 degrees take-off elbow
shipped with the appliance.
5. Each 90 degrees elbow installed on the horizontal
plane is equivalent to a 3 feet horizontal pipe;
therefore, 3 feet must be subtracted from allowable
horizontal run. (45 degrees elbow is equivalent to
18 inches horizontal pipe.)
6. All horizontal pipe runs must be graded 1/4 inch per
foot upwards in the direction of the exhaust flow.
The final pipe length, when terminating through the
wall may be graded downwards slightly to prevent
water migration.
7. A restrictor adjustment is required for most
installations having a vertical rise—see next
section.
Note: The restrictor is shipped installed at the
exhaust exit of the firebox.

Restrictor
The restrictor is located in the roof of the firebox hidden
above the top liner panel. Adjust the restrictor before
installation of the top liner panel. Should subsequent
adjustment be required, you will need to remove the
top liner panel—see page 29.
ALL INSTALLATIONS REQUIRE A RESTRICTOR for
improved flame picture and performance. This unit is
supplied with a pre-fitted restrictor having five different
positions or settings. The restrictor is shipped mounted
at the maximum open position which is used for rear
venting with no vertical rise. The level of restriction
required depends on the vertical rise in the venting
system and, to a lesser degree, the horizontal run and
number of elbows.
The amount of restriction is based on laboratory tests.
The ideal restrictor position may vary slightly, especially
when the vent pipe length is near the limits of the
acceptable configurations for each type of restrictor.
The chart on the previous page shows the vent
restrictor required relative to the length of the vent pipe.
To set the restrictor position:
1. Establish the required position of the restrictor
looking up the venting table on the previous page.
2. Release the screws (2) on each side of the restrictor
already installed.
3. Slide the restrictor in the required position.
4. Tighten the screws.

Vent Termination
• The vent terminal must be located on an outside
wall or through the roof.
• This direct vent appliance is designed to operate
when an undisturbed airflow hits the outside vent
terminal from any direction.
• The minimum clearances from this terminal that
must be maintained when located on an outside
wall are shown in the figure below. Any reduction
in these clearances could result in a disruption
of the airflow or a safety hazard. Local codes or
regulations may require greater clearances.
• The vent terminal must not be recessed into a wall
or siding.
• The vent terminal should be positioned where it will
not be covered by snowdrifts.
• Sidewall vent terminations within 7’ of grade require
a terminal guard.
