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 into the
OPEN position. Light the newspaper. Leave the
door partially opened to facilitate the start-up.
Step 3. Once kindling fire is well established,
cord wood can be added. You may set the
primary air control to the desired level (see
Primary Air Combustion Control section for
proper operation of the air controls). Close the
door and maintain an accelerated combustion
air set up in order to achieve combustor light-
off conditions.
Step 4. When the fire is burning well, and you
can see the gauge needle in the catalytic com-
bustor operating range, close the CAT bypass
damper control by pushing the control rod in. It
takes about 15–30 minutes with the CAT 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 with the 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 CAT Bypass fully (see Figure 5).
Step 2. Completely open the air control level.
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 500°F.

Step 3. Open the door about 1" and wait 5
seconds until the air flow has stabilized. Then
open the door completely, put the logs in and
close the door.
Step 4. Set the air control to the desired burn
level. Open the CAT bypass damper for 10 min-
utes before closing it. It will ensure sufficient
temperatures for combustor light-off.
To refuel the fireplace when the unit is still hot
(some burning fuel remaining or a glowing
combustor)
A. Open the air control and the CAT bypass
completely.
B. Open the door about 1" and wait 5 seconds
until the air flow has stabilized. Load the fuel,
close the door and CAT bypass (temperatures
within the firebox should be enough to
maintain catalytic operation).
C. Set the 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 back on to ensure
successful rekindling.
SMOKING –
CAUSES AND TROUBLESHOOTING
To reduce the likelihood of smoke coming
into the room when opening the door, set the
combustion air controls to the left ("Acceler-
ated Combustion") and open the CAT bypass
before opening the door. 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 door is partially opened - When you
open the door, open 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
(included with fireplace). 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.
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
D. Wet wood
Wet or tarred wood 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 twelve
(12) feet (3.7 m) 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 (3 m) of it. When
installed with offsets, the minimum chimney
height is fifteen (15) feet (4.6 m). 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 or a basement installa-
tion may generate back draft problems which
will cause start-up problems. To prevent this,
open a nearby window, roll up a piece of paper
and light it. Then, 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
when you open the fireplace door for reloading.

IMPORTANT CAUTIONS

A. Do not block any hot air vents from 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.
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 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
andirons.
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.
