Hearth Stove Installation (Uses existing masonry or Z.C. fireplace)
When installing the stove into an existing masonry or Z.C. fireplace (called a "Hearth Stove"
installation), there are two options for routing the pellet vent. Both options allow the use of
either type "L" pellet vent, stainless steel single wall liner, or flexible stainless steel liner.
NOTE: Z.C. (Metal) fireplaces require a positive connection installation.
¥ The first option is a direct connection. It relies upon a non-combustible block-off plate at the
damper location to form an air tight seal between the flue gases and the masonry chimney. It
must be sealed with Kaowool or high-temperature insulation. The pellet vent must extend a
minimum of 1' above the block-off plate or to the first flue tile if the chimney has a tile lining.
¥ The second option is a positive connection (also called a complete reline). An air tight cover
plate is required at the top of the masonry chimney (use 500 o F. RTV silicone to seal). A
positive connection is recommended because it is easier to clean.
Make sure to follow all of the requirements listed in the section "Stove Requirements" as well as
those listed below in the illustration. The steps below detail the order of installation.
A
Inspect the existing fireplace for any damage or deterioration. Repair any damage before
proceeding. If installing in a Z.C. fireplace, remove the damper to allow the pellet vent to
pass through the chimney.
B Install the floor protection.
C Install the pellet vent. Screw together all pellet vent joints and seal. Install the outside air
connection (if applicable).
NOTE: No modification to the Z.C. firebox is allowed.
D Place the pellet stove in position and attach the pellet vent and outside air connection (if
applicable). Screw together and seal the pellet vent connection to the stove.
E Read the section "Operating the Heater" prior to plugging in the stove and operating.
