Two common types of clearance reductions systems use sheet metal with a thickness of 28 gauge (galvanized steel, aluminum, copper)
or a 3-1/2 inch (4 inch thick nominal) thick masonry wall. Either of these materials must be spaced out 1 inch from the combustible
surfaces. With sheet metal, noncombustible spacers are used to maintain the 1 inch air space. With a masonry wall, metal wall ties
and furring strips, if needed, are used to anchor the brick to the wall. To avoid excessive heat transmission, the spacers or wall ties
should not be placed directly behind the heater or chimney connector. The 1 inch air space provides free air circulation. It is essential
that there be openings at the top and bottom of these clearance reducers so cool air can enter at the bottom and warm air exit at the
top. It is the “chimney effect” whereby when the air in the space is heated, it rises exiting from the top and being replaced by cooler
air at the bottom, that makes these shields effective.
Masonry, or other noncombustible products, attached directly to a combustible surface without an air space offer very little protection
and cannot be considered a clearance reduction system unless speci
fi
c materials have been tested and listed for direct attachment
to a combustible surface. The same applies to thin veneer brick and stone coverings. These materials provide adequate protection
only when mounted on sheet metal with a 1 inch minimum spacing to the wall.
A variety of prefabricated clearance reduction systems which have been safety tested and listed are available through heater dealers.
Always look for a safety listing label on the product when selecting a clearance reduction system through a heater dealer and make
sure it is designed for use with solid fuel. The manufacturers of these tested and listed systems provide speci
fi
c installation instruc-
tions that must be followed exactly for a safe installation.
Should you chose to make your own clearance reduction system, contact your local
fi
re department,
fi
re marshal or building code
inspector for speci
fi
c requirements regarding home-constructed clearance reduction systems and safe installation clearances to
protected combustible surfaces.
TO SAFELY AND PROPERLY INSTALL THIS HEATER:
1. Install a Listed High Temperature Type HT Factory-built Residential Type and Building Heating Appliance Chimney, build a ma-
sonry chimney or adapt an existing chimney to vent the heater. (See the CHIMNEY CONNECTOR AND CHIMNEYS section of this
manual for important information).
2. Purchase the 6-inch diameter chimney connector pipes that are required. The pipe should be black or blued steel, 24 gauge
minimum. If elbows are needed, use only seamless elbows because seamed elbows can leak smoke. Do not use more that two
elbows or the chimney draft will be restricted (See the CHIMNEY CONNECTOR AND CHIMNEYS section of this manual for details).
Number 8 sheet metal screws and furnace cement will also be needed to assemble the chimney connector pipes. If the heater is to
be installed to a masonry
fi
replace as shown by
fi
gure 4, you should also obtain the
fi
replace items called for by
fi
gure 4.
3. If the heater is to be installed on a combustible
fl
oor, purchase a listed noncombustible
fl
oor protector as described in this manual
and install it in the proper location. The
fl
oor protector MUST protect the
fl
oor beneath and around the heater and chimney connector
as shown by
fi
gure 5.
4. Assemble the chimney connector pipe sections to determine if the chimney connector pipe will correctly extend from the heater
fl
ue collar to the chimney. Any horizontal section of chimney connector pipe must slope upward at least 1/4” rise to the horizontal
foot to maintain adequate draft (See
fi
gure 6). Always install the chimney connector pipe with the crimped end toward the heater to
prevent creosote from leaking out of the joints (See
fi
gure 6). Always use the least number of chimney connector pipe sections pos-
sible. Minimum clearance to combustible walls and ceilings as noted by
fi
gures 1 through 4 MUST always be maintained if a clearance
reduction system is not installed.
5. After it is determined that the assembled chimney connector will properly connect the heater to the chimney, disassemble all sec-
tions of the chimney connector in preparation for the
fi
nal assembly procedures.
6. Place the crimped end of the
fi
rst chimney connector pipe or elbow into the heater’s
fl
ue collar and mark it through each of the
holes in the heater’s
fl
ue collar.
7. Remove the pipe or elbow from the
fl
ue collar and drill 1/8 inch diameter holes at the points marked by step 6.
8. Apply furnace cement to the inside surface of the heater’s
fl
ue collar, reinstall the
fi
rst pipe or elbow and fasten in place with No.
8 sheet metal screws. Apply additional furnace cement to the outside of the chimney connector
fl
ue collar joint if an airtight seal was
not achieved when the pipe or elbow was installed.
9. Assemble the remaining chimney connector pipes by applying furnace cement to the joints, drilling 1/8 inch diameter holes for and
attaching each joint with three No. 8 sheet metal screws. Wipe all excess furnace cement from the pipe joints with rag or paper towel.
Allow the applied cement to dry before building the
fi
rst
fi
re in the heater.
10. Depending on your particular type of installation, connect the heater’s chimney connector to a masonry chimney as shown by
fi
gures 7 or 8, or connect the chimney connector to a metal prefabricated chimney as speci
fi
ed by the instructions furnished with the
metal prefabricated chimney or connect the chimney connector to a masonry
fi
replace as shown by
fi
gure 4.
DANGER: IF ANY CLEARANCE TO UNPROTECTED WALL OR CEILING IS LESS THAN THOSE SPECIFIED BY FIGURES 1
THROUGH 4 AFTER HEATER INSTALLATION IS COMPLETED, A CLEARANCE REDUCTION SYSTEM MUST BE INSTALLED
BEFORE THE FIRST FIRE IS BUILT IN THE HEATER; OTHERWISE, THE UNPROTECTED WALL OR CEILING COULD CATCH
FIRE. REMEMBER, THERE ARE ALSO LIMITS AS TO HOW CLOSE THE HEATER CAN BE INSTALLED TO A COMBUSTIBLE
SURFACE PROTECTED BY A CLEARANCE REDUCTION SYSTEM. REREAD “MINIMUM CLEARANCES TO WALLS AND
COMBUSTIBLE WALLS AND CEILINGS” PRESENTED EARLIER IN THIS MANUAL.
CAUTION: FOR YOUR SAFETY, CONTACT YOUR LOCAL FIRE DEPARTMENT, FIRE MARSHAL, OR BUILDING CODE INSPEC-
TOR FOR INSPECTION PRIOR TO AND FOLLOWING CLEARANCE REDUCTION SYSTEM AND/OR HEATER INSTALLATION.
