Step 3. Open the doors about 1” and wait 5
seconds until the air flow has stabilized. Then
open the doors completely, put the logs in and
close the doors.
Step 4. Set the primary air control to the
desired burn level. Open the bypass damper
for 10 minutes before closing it. It will ensure
sufficient temperatures for combustor light-off.
To refuel the WCT6940WS fireplace when the
unit is still hot (Some burning fuel remaining
or a glowing combustor)
A. Fully open the primary air control and the
bypass completely.
B. Open the doors about 1” and wait 5 seconds
until the air flow has stabilized. Load the fuel,
close the doors and bypass (temperatures
within the firebox should be enough to
maintain catalytic operation).
C. Set the primary air control to the desired
burn level.
NOTES:
• For spectacular fire and optimization of the
fireplace efficiency, we recommend that the
wood load be placed as far back as possible.
• It may be necessary to turn off any blower(s)
in operation during the refueling process in
order to minimise smoking in the room. It
is recommended to wait 15 to 30 minutes
before turning the blower(s) back on to
ensure successful rekindling.
SMOKING –
CAUSES AND TROUBLESHOOTING
To reduce the likelihood of smoke coming
into the room when opening the doors, set
the combustion air controls to the left (“Ac-
celerated Combustion”) and open the bypass
before opening the doors. Your fireplace has
been designed and tested to provide smoke
free operation.
As the fire burns, air goes up the chimney.
This air must be replaced through the outside
air duct. When operating the fireplace, open a
nearby window temporarily to check if there is
adequate replacement air supply. Occasionally,
there may be a small amount of smoking upon
lighting the fire, until the chimney heats up but
this should not last. If the fireplace continues
to smoke it is probably for one of the follow-
ing reasons:
A. The doors are partially opened - When you
close the doors, close them completely.
B. Negative pressure in the house -
As the
fire burns, air goes up the chimney. This
air must be replaced through leakage into
the house or through the outside air duct
(optional). When operating the fireplace,
open a nearby window temporarily to check
if there is adequate replacement air supply.
C. Fans operating (e.g.: range hood) - These
fans draw air out of the house and may
actually cause a negative pressure in the
house. Turn off all fans and open a nearby
window to determine if this is the cause of
the problem.
D. Wetwood - Wet or tarredwood will smoulder
and smoke instead of burning properly.
Your
dealer can help you determine if you have
properly seasoned wood for burning.
E. Dirty or blocked chimney - Check to make
sure the chimney is clear and clean.
If
dirty call a certified chimney sweep or use
a properly sized chimney brush to clean.
F. Chimney not long enough - The minimum
chimney height is 12 feet not including the
fireplace height. The chimney must extend at
least three (3) feet (915 mm) above its point
of contact with the roof and at least two (2)
feet (610 mm) higher than any roof or wall
within ten (10) feet (3m) of it. When installed
with offsets, the minimum chimney height is
15 feet. Additional height will increase draft
and will decrease the tendency to smoke.
G. Poor chimney draft
With no fire, there should be sufficient draft
to exhaust cigarette smoke introduced under
the baffle. Chimneys installed against an
outside wall without protection may gener-
ate back draft problems which will cause
start-up problems. To prevent this, open
a nearby window; roll up a piece of paper,
light it and hold it in the upper part of the
firebox to warm up the chimney. Wait until
the draft is sufficient, then start the fire.
H. Blower for forced air kit operating - Make
sure that the blower is at the “off” position
whenyouopenthe fireplacedoorforreloading.
IMPORTANT CAUTIONS
A. Do not block the openings at the top of the
fireplace as this will cause the fireplace to
overheat.
B. Never use gasoline, gasoline-type lantern
fuel, kerosene, charcoal lighter fluid, or
similar liquids to start or ‘freshen up’ a
fire in this fireplace. Keep all such liquids
well away from the fireplace while it is in
use.
C. Do not burn coal. The sulphur in coal will
corrode the firebox and chimney.
D. Do not burn driftwood which has been in the
ocean or salt water. The salt will corrode
the firebox and chimney.
E. Do not operate the unit with the door(s)
partly open since this may cause smoke
to be drawn into the room.
F. Do not burn wood in the area in front of the
grate.
G. Do not abuse the unit by burning paper, or
cardboard or construction material such as
pressed wood, plywood or lumber. Wood
protectors, metallic paper, coal, plastic,
waste, sulphur and/or oil will damage the
fireplace.
H. Do not allow the wood to smoulder or burn
without flame, since this will produce
excessive creosote in the unit
as well as
increased particulate emissions.
STARTING AND MAINTAINING A FIRE
Step 1. Place several crumpled up balls of
newspaper in the firebox. Place small dry pieces
of kindling on top of the paper, criss-crossing
the kindling so that there are air spaces in
between. The kindling should be placed at the
center of the firebox so as to allow for sufficient
air circulation.
Step 2. Adjust the primary air control and pull
the bypass damper control towards you to put
it in the OPEN position. Light the newspaper.
Leave the doors partially opened to facilitate
the start-up.
Step3. Once the kindling fire is well established,
cord wood can be added. Close the door and
maintain an accelerated combustion air setup in
order to achieve combustor light-off conditions
(See Primary Air Control Section).
Step 4. When the fire is burning well, close the
bypass damper control by pushing the control
rod in. It takes about 15 – 30 minutes with
the bypass opened to reach proper light-off
temperatures for the catalytic combustor.
Step 5. Set the primary control to the desired
burn level. The fireplace will automatically go
to that level after the fire is fully established.
The unit will burn best with 2-3 pieces of cord
wood spaced 1 to 2 inches apart and allowing
air to get under the fuel. Criss-crossing or ar-
ranging the fuel so that air can get underneath
will help the fire to get started easily. The unit
should be operated withthe air control fully open
long enough to get the cord wood well ignited.
REFUELING FOR BEST PERFORMANCE
To refuel the fireplace at the end of a burn cycle
when only hot embers remain and flames are
gone (not enough heat to maintain catalyst
operating temperatures):
Step 1. Open the bypass and air controls fully
(see Figure 1).
Step 2. Completely open the primary air control.
See Figure 2.
REFUELING: During the refueling and
rekindling of a cool fire, or a fire that has
burned down to the charcoal phase, operate
the stove at a medium to high firing rate for
about 10 minutes to ensure that the catalyst
reaches approximately 400°F.
