OPERATION GUIDELINES
When a AK4 combustion air assembly and a combustion air duct are attached to the connecting point on the
left or right side of the fireplace, combustion air may enter the firebox through a dampered opening behind the
left or right side brick. This feature is designed for your benefit to reduce the room air used for combustion and
to prevent excessive loss of heat from the room. When the fireplace is in use, this damper should be open.
When the fireplace is not in use, the damper should be closed to prevent cold air from entering the firebox. The
combustion air damper is open when the lever, located on the left and right side of the firebox near the top of
the firebrick, is up and closed when the lever is down.
Outside air for combustion is optional unless required by federal, state or local building codes. See the section
of this manual providing the instructions for installation of the combustion air assembly. The design of the
fireplace allows the routing of the combustion air duct up, down, or horizontally to obtain the outside combustion
air. This permits flexibility in planning your installation. See Figure 22 for typical installation methods. Review
the precautions and recommendations in this manual pertaining to outside combustion air installation.
Glass doors should be installed to receive the maximum benefit from your fireplace. For large fires, the
maximum heating benefit from the fireplace will be obtained with the doors open due to the high amount of
radiant heat being emitted out of the front opening of the fireplace. With a small fire, or before retiring in the
evenings, it is best to operate the fireplace with the doors closed to prevent excessive room air form being
drawn up the chimney. When the doors are open, the mesh screens should be closed to help keep burning
embers from popping out of the firebox.
The fireplace also is equipped with a flue damper, which must be open when the fireplace is in use. The flue
damper control lever is located inside the fireplace. The counterweighted damper is operated by simply
pushing up to open or pulling down to close the damper. When the fireplace is not in use, the damper should
be closed to prevent cold air form entering the chimney as well as preventing warm air in the room from
escaping up the chimney.
NOTE: It is normal for a small amount of smoke to be released from the upper portion of the fireplace the first
few times you use your new fireplace. This results from an oil residue on the metal. Open a door or window
to allow the smoke to escape.
The grate included with this fireplace helps to appropriately locate and contain the burning wood. Failure to
use this grate may cause overheating of parts of the fireplace and allow large pieces of burning wood to roll
forward out of the firebox. If the grate becomes warped or damaged, it must be replaced with grate number
072954 only.
WARNING: Fireplaces equipped with doors should be operated only with the doors fully open or doors fully
closed. If doors are left partly open, gas and flame may be drawn out of the fireplace opening, creating risks
of both fire and smoke.
All fireplace chimneys are in direct contact with cold air on the exterior of the structure. Consequently, when
the fireplace is not in use, cold air can fall down the chimney of the fireplace to cool off the fireplace chase.
Therefore, the fireplace chase must be insulated to minimize the risk of cold air infiltration to the home. Even
if the fireplace chase is adequately insulated, this cannot completely ensure that cold air infiltration into the
structure will be eliminated. Cold air infiltration is a possibility with any fireplace or device that freely
communicates with the air on the outside of the structure. Today’s homes are more energy-efficient and,
therefore, better insulated and tightly constructed. Unfortunately, when air is removed from the house, as by a
bathroom fan, or consumed by a furnace, additional air is needed to replace the air consumed. Unless the
additional air is supplied, this can cause a negative pressure in the home. When this happens, the house will
draw in outside air form the cracks in the windows, down the fireplace flue or other locations of air leakage in
the home. Because cold air infiltration may be unavoidable in some structures, Monessen Hearth Systems is
not responsible for heat loss or air infiltration through or around the fireplace.

FIREPLACE LOCATION
CAUTION: Do not install fireplace over carpeting.
This fireplace does not weigh more than large pieces of furniture and can normally be located near a load
bearing wall without requiring additional foundations or supports. If however, the fireplace is to be trimmed
with a heavy stone or brick facing and hearth extension, be sure the supporting structure is adequate.
Figures 4 and 5 provide dimensional details of the fireplace, required spacing to combustible walls, and some
suggested fireplace locations. When selecting a location, choose one that is away from frequently opened
doors, central heat outlets or returns, or other places where air movements may disturb the airflow around the
fireplace. Air turbulence near the fireplace may cause smoke to spill out of the fireplace opening.

Survey the planned location for the fireplace for overhead plumbing or electrical wires, etc., that might complicate
the installation or endanger persons installing or cleaning the chimney. Avoid a location where the chimney
cap will be near abrupt changes in the roof shape, nearby wall or embankments, under or near trees or above
the roof of a single story wing of a two story building as shown by Figure 8. All these conditions can cause
turbulence or pressure conditions that can cause poor chimney draft and smoke spillage from the fireplace
opening. Elbows may be used to offset the chimney to avoid obstructions or to locate the chimney cap in a
preferred location. Refer to the sections of this manual pertaining to chimney offsets for instructions on proper
elbow use. Poor installation or location of the chimney cap and/or components can cause wind blown rain to
enter the chimney.
Be sure the selected location will allow a 17" square combustible material-free space for the chimney to pass
through. If the chimney is to pass through living or storage spaces, be sure there is adequate space to enclose
the chimney to avoid personal contact with, or damage to, the chimney. If the fireplace is to be installed on an
outside wall, the surrounding walls (chase) should be constructed and insulated as shown by Figure 6. Failure
to insulate the fireplace form outside temperatures will cause heat loss through and around the fireplace.

FLOOR PROTECTION
If this fireplace is installed on a combustible floor, the floor area 20 inches in front of, and 12 inches either side
of the fireplace opening must be protected by an insulating noncombustible hearth extension. This hearth
extension may be either minimum 6-inch thick stone or brick as shown by Figure 10, a H2074 hearth exten-
sion kit or a locally constructed hearth equivalent to the H2074.
The H2074 hearth extension kit consists of sufficient insulation board to cover the 20" x 74" floor area with ˚
inch layer of insulation. A 20" x 74" piece of galvanized steel is included in the kit to cover the insulation before
a finishing layer of noncombustible material of stone, brick, tile, etc., is applied to finish the hearth extension.
The insulation used in the H2074 hearth extension has a thermal conductivity (K factor) of 0.43. If you do
construct a hearth extension equivalent to the H2074, be sure the insulation you use has enough compressive
strength to support the weight of the covering materials and persons standing on it, and insulating qualities
equal to or better than the 1/2" covering provided by the H2074.
