Read Sheet GS for important clearance and safety precautions before installing any of the parts described by this sheet. Sheet GS is packaged with Supports.
These MetalBest Chimney Systems Ceiling Supports (FSP
and CSP) are intended for installation below both finished and
unfinished ceilings. The round or square fire stop plate fits up
against a ceiling, or a joist opening framed level on all four sides.
It is adaptable to all types of chimney-connected appliances,
including freestanding fireplaces, solid fuel room heaters,
furnaces, stoves and both gas and oil-burning equipment. To
start a vertical ceiling-supported chimney, simply place a length
of Chimney Systems pipe, at least 18 inches long, in this
isupport. See Fig. 1.
FINISH CEILING SUPPORT (5”, 6”, 7”, 8”)
CEILING SUPPORT (10”, 12”, 14”)
Follow these steps to install:
1. Frame a level square opening (all four sides), such that the
inside dimensions are 6-1/4" larger than the diameter (ID) of
pipe being installed. For example if a 6" MetalBest Chimney is
being installed, the framing dimensions should be 12-1/4" x
12-1/4".
4. Put one 8 penny common nail part way into each of the four
nailing areas of the assembly and check that the plate is level
and flush to the ceiling.
5. Finish nailing with 8 penny nails through all pre-punched holes.
6. Attach trim plate to ceiling or to framing at corners.
ATTACH CONNECTORS SECURELY AND OBSERVE
CLEARANCE TO COMBUSTIBLE MATERIAL
The connector or smoke pipe is the sheet metal pipe between
the appliance and the chimney. Different types of fuels and
appliances have different connector clearances to combustible
walls and ceilings. These clearances will be shown in the
appliance instructions.
Whatever clearances and connector arrangements are shown in
the appliance instructions, they must be followed rather than
the arbitrary 18 inch dimension. This is important if tests have
shown that more than 18 inches clearance is necessary, or if
the location of the stove or heater necessitates more clearance.
See Fig. 3.
Combustible materials include such things as framing lumber,
plywood, drywall (sheet rock, plaster board, lath and plaster,
gypsum board) and also furniture and curtains. Building insulation
of any kind including batts. foams, boards and especially loose
fill cellulose fiber, must also be kept away from the chimney in
the same manner as combustible materials.

WARNING
!
Failure to follow the instructions could cause
FIRE, CARBON MONOXIDE POISONING, OR DEATH. If you
are unsure of installation requirements, call the Phone
Number listed on the instructions or visit www.selkirkcorp.com
The support must be underneath either the framed opening
or the finished ceiling. DO NOT INSTALL SUPPORT
ABOVE THE FRAMING. See Fig. 2
Note:
2. Install finish ceiling material. Cut a circular opening the same
diameter as the framing dimension (or square) through the ceiling
inside the framed opening, making it large enough to accept the
support. (With an existing ceiling, the opening should be framed
after cutting the hole.)
3. Place the support assembly up against the ceiling opening
from below.
