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.

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

.

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.

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.
