OPERATIONAL GUIDELINES
CHIMNEYS
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 fire-
place to cool off the fireplace chase. Therefore, the fireplace
chase must be insulated to minimize the risk of cold coming
into the home. Even if the fireplace chase is adequately
insulated, this cannot completely ensure that cold air coming
into the structure will be eliminated. Cold air coming inside
is a possibility with any fireplace or device that freely uses
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 (by a bathroom fan or consumed by a furnace) addi-
tional 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 coming in may be unavoidable in some structures, MHSC
is not responsible for heat loss or air infiltration through or
around the fireplace.
FLUE DAMPER
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 unlocking up to open or pulling
and locking 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 MHSC fireplace. This results from an oil
residue on the metal. Open a door or window
to allow the smoke to escape.
GRATE
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.
Replace warped or damaged grate only
with a MHSC grate.
