OPERATIONAL GUIDELINES
CHIMNEYS
All replace chimneys are in direct contact with cold air on
the exterior of the structure. Consequently, when the replace
is not in use, cold air can fall down the chimney of the re-
place to cool off the replace chase. Therefore, the replace
chase must be insulated to minimize the risk of cold coming
into the home. Even if the replace 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 replace or device that freely uses
air on the outside of the structure. Today’s homes are more
energy-efcient 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 replace ue
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 inltration through or
around the replace.
FLUE DAMPER
The replace also is equipped with a ue damper which must
be open when the replace is in use. The ue damper control
lever is located inside the replace. The counterweighted
damper is operated by simply unlocking up to open or pulling
and locking down to close the damper. When the replace 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

GRATE
The grate included with this replace helps to appropriately
locate and contain the burning wood.
Failure to use this grate may cause
overheating of parts of the replace
and allow large pieces of burning
wood to roll forward out of the rebox.
Replace warped or damaged grate only
with a MHSC grate.
