CHIMNEYS: FACTORY-BUILT FIREPLACE
In Canada and in the U.S.A.:
If the insert is installed into a factory built fireplace the chimney must be lined from the
outlet of the insert to the top of the chimney using a Stainless Steel liner which meets
UL1777
or
ULC S635
. The liner
must be securely attached to both the insert and the chimney top.
In both Canada and the U.S.A. the existing fireplace damper must be secured in the open position. If this is not possible
the damper must be removed. Any openings between the masonry of the fireplace and the facing masonry must be
sealed.
GENERALCHIMNEY INSTALLATION
Connect the venting system to the flue collar of the insert using three sheet metal screws. There are three predrilled
holes in the flue collar. Place a bead of furnace cement around the flue collar connection to ensure the flue pipe is
properly connected, secured and sealed.
If this stove and its chimney components are not properly installed, a house fire may result. For your safety, follow the
installation directions. Contact local building or fire officials about restrictions and installation requirements in your area.
We recommend that the inside your chimney be at least the same diameter as the flue of your stove. If you plan to use
an existing masonry chimney, be sure it is free of cracks and loose joints. Gases traveling through a chimney can reach
extremely high temperatures. Cracks or loose mortar can allow hot gases to reach the wood portion of the structure
surrounding the chimney. These toxic gases can also re-enter the house through cracks and small holes in the chimney,
or cause back-puffing which will result in excessive smoking. Be on the safe side and have your chimney inspected by a
certified chimney sweep. A 6 inch stainless steel chimney liner with a direct connection to the stove is recommended for
masonry chimney installations.
A chimney must extend at least three feet above the highest point where it passes through the roof and at least two feet
higher than any portion of the building within ten feet of the chimney. Smoke travels up the chimney in a circular,
spiraling motion. A 6 inch round stainless steel liner allows the smoke to travel with less resistance. A rough masonry
chimney without a good smooth liner can result in the rapid build up creosote..
Before you begin check all local codes and regulations regarding your installation.

DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.

CHIMNEY DRAFT
Draft is the force which moves air from the appliance up the chimney and pulls fresh, oxygen-rich air into the combustion
chamber. Your stove cannot force smoke up the chimney but rather your chimney must always "suck" the smoke out of
your stove. The smoke will always try to go to the area of lowest pressure. The rate of draft in your chimney depends on
many factors including the length of your chimney, local geography and
nearby obstructions. Too much draft can cause excessive temperatures
in the appliance and may damage the unit.
Inadequate drafting may cause back puffing into the room and plugging
of the chimney. Inadequate draft may also cause the appliance to leak
smoke into the room through the appliance and flue connector joints.
An uncontrollable burn, glowing red stoves part or flue connectors, may
indicate excessive draft. Poor burn times or failure of the appliance to
"get hot", or "burn hot", can be the result of inadequate chimney draft. If
the stove is vented into an exterior masonry chimney, and the draft is
inadequate, you will most likely need to line the inside of the chimney
with a stainless steel liner.
Excessive draft can result in over firing, short burn times and can possibly damage the internal components of the stove.
