OPERATION GUIDELINES
As wood is burned in the fireplace, room air entering the fireplace through vents is circulated around the firebox of
the fireplace. This air circulation protects the firebox from overheating. Fireplace vents must not be blocked or
restricted in any manner. Blocking or restricting air circulation through the fireplace can cause a fire hazard.
In residential type installation, an AK4 outside combustion air kit may be connected to either the left or right side of
the fireplace to allow outside air to enter the firebox through a dampered opening in that side of the fireplace. This
“outside combustion air” feature reduces the room air used for combustion and prevents excessive heat loss from
the room. When the fireplace is in use, the fireplace’s “outside combustion air” damper connected to an AK4 may be
opened to allow air from outside to enter the fireplace firebox. When the fireplace is not in use, the “outside combustion
air” damper should be closed to prevent cold air from entering the firebox. An “outside combustion air” damper is
open when its control lever is up, and closed when its control lever is down. A control lever for each “outside
combustion air” damper is located inside the firebox near the top of the side firebrick on each side of the fireplace.
The design of the fireplace allows the routing of the combustion air duct downward or horizontally to obtain the
outside combustion air; this permits flexibility in planning your installation. See Figures 24 thru 27 and their instructions
for typical installation of outside combustion air kits. Review the precautions and recommendations in this manual
pertaining to outside combustion air. Outside air for combustion is optional in residential type installations
unless required by local codes; it is mandatory in manufactured home installations. Use an AK6 outside
combustion air kit in manufactured home installations, instead of the AK4 offered for residential type
installations.
Glass doors (model MGD36B or MGD36PB by Monessen Hearth Systems) may 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 from 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.
Glass doors are mandatory on fireplaces installed in manufactured homes.
WARNING: Fireplaces equipped with glass doors should be operated only with the glass doors fully open or 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.
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 Monessen Hearth Systems 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 only be replaced by a Monessen Hearth Systems 078355
grate.
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 from 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 14-1/2" 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 16 inches in front of, and 8 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 H1652 Hearth Extension
Kit or a locally constructed hearth equivalent to the H1652.
The insulation used in the H1652 hearth extension has a thermal conductivity (K Factor) of .43. If you do
construct a hearth extension equivalent to the H1652, 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 ˚" covering provided by the H1652.
