Exception F200 Wood Insert

Masonry Direct Connect Installation
This method is most commonly used because it is
less expensive than the other methods. A steel block-off
plate is used to seal off the chimney and allow the chim-
ney connector to pass through and extend into the begin-
ning of the tile flue liner. If the steel plate is impractical
because of some odd fireplace construction, fiberglass
insulation may be packed around the chimney connector.
To seal the flue from the living space of the home, if
this is the method used, a chimney cap is recommended
to prevent the fiberglass from being exposed to the rain.
If the masonry chimney flue cross-sectional area is
greater than 3 times that of the insert which is 28.27 sq.
in. it is recommended that a positive connect installation
be used.

Masonry Positive Connect Installation
This method is recommended when the tile linner is
damaged beyond repair or the chimney has historically
had low draft problems. The liner listed to UL-1777 can
be rigid or flexible with a chimney cap and top sealing
plate installed

For direct connect and positive connect
installations, ensure that the liner is
securely connected to the insert flue collar.
