We recommend that our gas
hearth products be installed and
serviced by professionals who
are certied in the United States
by NFI (National Fireplace
Institute®).
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” (0.9 m) IN FRONT OF THE FIREPLACE.
CHILDREN and PETS
Radiant heat can heat surfaces such as the hearth in front of the replace to temperatures
that, although approved safe, can be quite uncomfortable to touch or step on—particularly
for children and pets. Children and pets should always be supervised when in the room
where the appliance is located. Remote control handset should be kept out of reach of
children. In the presence of children, we STRONGLY RECOMMEND that you install in front
of the replace: a re screen, doors or, to protect young toddlers, a “hearth gate”—see
Options on page 40.
HOT SURFACES
Be aware that, although safe, some combustible materials and nishes, even though
installed at listed clearances may, over time, discolor, warp or show cracks. The 1200DV
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 replaces or near the
edge of protrusions unless appropriate.
The information contained in this installation manual is believed to be correct at the time of printing.
Miles Industries Ltd. reserves the right to change or modify any information or specications without

Hearth Requirements
SAFETY WARNING! The Ventana is a very effective radiant heater. The hearth/oor in front of
the heater can get very hot (in excess of 200ºF). Locating the unit raised above the hearth/oor
or adding one of the optional screen fronts or a generic freestanding screen in front of the unit
can greatly reduce hearth temperatures. Any hearth within 4” of the base of the heater must
be constructed of non-combustible materials (see diagrams in the following pages). Note that
some materials, although safe can degrade due to heat—take this into consideration when
choosing materials.
General Hearth Considerations
Top of Finished Hearth
Must Be Flush With
Bottom of Heater to
accommodate some
optional mantels and
trims. See Option section
towards the end of this
manual for optional
accessories.
NOTE:
Unit will need to be raised
in almost every case to
accommodate hearth or
combustible ooring.
Non-combustible hearth
required if bottom of
replace is less than 4” from
combustible oor in front.

Rules
Any hearth/oor in front of replace within 4” of bottom of unit must be non-combustible and project a minimum
distance as shown on page 14. The hearth/oor must have a non-combustible nish applied over the 1/2”
insulation board provided with the engine. This insulation board acts as a thermal break.
Minimum hearth projection is determined by a combination of the height of the hearth above the surface of
combustible oor or carpet and distance between hearth and bottom of replace.
Combustible baseboards (1” thick or less) located on wall are acceptable provided they are located below the
base of the raised replace.

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 roof or wall termination.
The total length of the vent pipe cannot exceed 40’
(12.2m).
The minimum vertical height with roof termination is
6’ (1.83 m).
Any combination of rise and run can be used as long
as they are within the allowable limits shown on the
chart below.
A maximum of 4 x 90° elbows—or equivalent (2 x
45° = 90°)—can be used.
1.
2.
3.
4.
Each 90° elbow installed on the horizontal plane is
equivalent to a 3’ horizontal pipe; therefore, 3’ must
be subtracted from allowable horizontal run. (45°
elbow is equivalent to 18” horizontal pipe.)
All horizontal pipe runs must be graded 1/4” per foot
upwards in the direction of the exhaust ow. The
nal pipe length, when terminating through the wall
may be graded downwards slightly to prevent water
migration.
Co-linear venting is not allowed.
A restrictor is required for many installations—see
next section.

Restrictor
MANY INSTALLATIONS REQUIRE A RESTRICTOR
for improved ame picture and performance, This unit is
supplied with one restrictor having four different positions
or settings. 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 congurations for each type of restrictor.
The chart on the previous page shows the vent restrictor
required relative to the length of the vent pipe.
Venting
To install the restrictor:
On an engine previously installed, open the panels
on each side of the window. Remove the window
skirt, the window, the logs, the right and rear top brick
panels.
According to the installation, look up the venting
chart on the previous page to know what position the
restrictor should be tted in.
Remove the screws (2) on each side of the venting
port.
Place the restrictor in the required position over the
two holes.
Fit the screws and tighten.
Continue the installation or, for an engine previously
installed, replace the right and rear top brick panels,
the logs, the window and the window skirt. Close the
side panels.

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 airow 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 gure below. Any reduction in these
•
•
•
clearances could result in a disruption of the airow
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.
