3.2 OPERATING THE MONACO
3.2.1 Fuel
The MONACO is designed to work best when fuelled with seasoned cordwood. Use solid
wood or processed solid fuel firelogs only. Hardwoods are preferred to softwoods since the
energy content of wood is relative to its density. Hardwoods will result in a longer burning
fire and less frequent refuelling. A moisture content of 15% to 20% (seasoned) is
recommended. Wood that has been cut and split and let to dry under a cover for a period of
one year will usually meet that criteria. Excessively wet wood will be difficult to burn and
will result in lower efficiency, increased creosoting and deposits on the glass and in the
chimney. Excessively dry wood will burn well but will also have higher emissions and shorter
burning time.
Do not burn scrap or garbage, treated wood or wood such as driftwood from the ocean which
has been exposed to salt or other chemicals. Salt or chemicals can corrode the firebox and
chimney. Do not burn large amounts of paper, cardboard, Christmas tree branches or building
construction materials. Intense firing with these materials may overheat the fireplace, causing
damage to the unit, a fire or even possibly igniting a chimney fire if the chimney is creosoted.
CAUTION:DO NOT OVER FIRE THIS HEATER OVER FIRING CAN RESULT IN A SAFETY HAZARD AND
CAN PERMANENTLY DAMAGE THE FIREPLACE AND CHIMNEY.
3.2.2 The use of manufactured logs
There are numerous types of manufactured logs sold on the market. You must be very
careful with this type of product. Many brands of manufactured logs contain chemical
additives. DO NOT BURN ANY MANUFACTURED LOGS CONTAINING CHEMICAL
ADDITIVES. IF YOU DO, YOU MAY OVERHEAT YOUR FIREPLACE, THEREFORE
CAUSING A FIRE HAZARD AND VOIDING YOUR WARRANTY. Logs containing
chemical additives burn a lot hotter and were designed for decorative fireplaces. Decorative
fireplaces generally have larger, cooler, and less air-tight fireboxes. Your MONACO, on the
other hand, has a smaller, completely sealed firebox which attains much higher temperatures.
It is therefore not designed to support excessive heat caused by the addition of chemicals in
manufactured logs. Manufactured logs made of 100% wood residues do not pose a threat to
your fireplace. However, they must be used carefully. Manufactured logs typically release a
much larger heat output over a short period of time. Therefore, you cannot place a large
quantity of such logs into your fireplace. Start with one log, and gradually increase the load.
Never put more than 4 logs. The logs should be of an average size and not exceed 8 inches in
diameter.
WARNING: Do not poke or stir the logs while they are burning. Use only firelogs that have
been evaluated for the application in fireplace and refer to firelog warnings and caution
markings on packaging prior to use.

6
3.2.3 First Fires
The fresh paint on your fireplace needs to be cured to preserve its quality. Once the fuel load
is properly ignited, only burn small fires in your fireplace for the first four hours of operation.
Never open the air control more than necessary to achieve a medium burn rate. Make sure
that there is enough air circulation while curing the stove. Open one or more windows. The
odours can be smelled during the 3 or 4 first fires.
3.2.4 Building a Fire
To start a fire, place several crumpled up balls of newspaper in the firebox behind the andiron.
Place small dry pieces of kindling on top of the paper, criss-crossing the kindling so that there
are air spaces in between. Keep the fuel far back enough so that air can get underneath. Open
the air controls fully and light the newspaper. Once the newspaper and the kindling is well
ignited, close the door. Once the kindling fire is well established, cordwood can be added.
(See Primary Air Combustion Control section for proper operation of the air controls.). Make
sure that cordwood is always behind the andiron.
The unit will burn best with 2-3 pieces of cordwood spaced 1 to 2 inches apart and allowing
air to get under the fuel. Criss-crossing or arranging 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 cordwood well ignited
3.2.5 Maintaining the Fire
Once the wood has been consumed (or partially consumed) and you have obtained a good bed
of embers, you should reload the unit. In order to do so, open the air control to its maximum
for approximately 15 seconds prior to opening the fireplace door. Then, proceed by opening
the door very slowly. Open it by 2" to 4" (52 to 104 mm) for 10 seconds before opening it
completely. This procedure will increase the draft and thus eliminate the smoke which is
stagnant in a state of slow combustion in the fireplace. Then, bring the red embers to the front
of the stove and reload the unit.
Your MONACO fireplace will work best if a thick bed of hot embers is maintained in the
bottom of the firebox, and a minimum of two large pieces of seasoned fuel are added.
Combustion efficiency is largely related to establishing a hot ember bed, and hot firebox
temperatures. The quicker the fireplace and chimney (flue) get up to normal operating
temperatures, the better. A small intense fire is preferred to a large smouldering fire, both to
improve combustion efficiency and to reduce the amount of creosote build-up. The best
performance will be obtained by adding relatively small amounts of fuel to a well established
ember bed, and then operating with the air inlet control open long enough to achieve a hot
fire. Use a poker to make an air channel in the embers below the wood. This will allow air to
flow under the wood for a more efficient burn. Once you have reached the desired
temperature, the primary air can be set to a medium setting. You know you have reached the
desired temperature when, closing the primary air control, you can see a flame at the top of

7
the firebox. The benefit of this technique will be cleaner glass, less creosoting, greater
efficiency and the most pleasing fire for your enjoyment.
In order to achieve an optimum efficiency from your unit, we suggest that you operate it with
the air control completely closed. Make sure that you have a good fire going and an adequate
ember bed before you completely close the air control. Closing the air control too soon will
lower combustion efficiency and may cause the fire to die out. The addition of a blower (if
not already included) is highly recommended to maximize your unit’s efficiency.

8
3.2.6 Primary Air
There is no flue damper in the MONACO. As in common with air tight stoves, the
combustion air control sets the flow of air entering the firebox. This allows for a more precise
control of the fire. The combustion air control is located below the door on the right side. The
main source of air (primary air) entering the firebox can be diminished by moving the air
combustion control from right to left. The primary air is fully opened when the air control is
completely moved to the right. The combustion air control should be in the closed position
(primary air) when the fireplace is not in use. This will minimize air leakage up the chimney.
The combustion air control should be opened before opening the door to minimize the
possibility of back draft coming into the room.

3.2.7 Combustion Settings
Accelerated Combustion
The maximum heat output for the MONACO is achieved by burning with the door closed and
the combustion air opened. By this method, the MONACO can produce up to 75,000 BTU of
heat per hour. However, it will be necessary to reload with wood every one or two hours. This
is the least efficient method of burning the MONACO. Use caution when firing with the
combustion air control wide open. Only burn cordwood in this manner. Small dry pieces of
softwood and construction scraps will burn very intensely using this method and may damage
the firebox.

9
Medium Combustion
This is the recommended mode of operating the MONACO and should be the one normally
used since it will deposit the least amount of creosote on the glass and in the chimney. The
combustion air control must be ¾ closed. The precise setting will depend on many factors,
including chimney length and the moisture content of the wood.
For instance, a long chimney will necessitate closing the combustion air control. To obtain the
proper combustion, close the combustion air control completely, then open it about ¼" to ½".
Three medium size pieces of wood should be burning on a bed of hot coals. The heat output
will be approximately 35,000 BTU per hour and the loading time will be about every 3-4
hours. Softwoods may be burned using this method but the time will be substantially reduced.
Slow Combustion
When the air combustion control is completely closed, the fireplace is in a slow combustion
phase. If the heart is hot enough, slow combustion will not stop the fire, but there will be a
noticeable change in the flame pattern. The flames will be slow and may appear dirty if the
wood is too wet (moisture content of 20% and more). Do not allow the wood to burn without
flame, since this will produce excessive creosote in the unit.
Creosote may accumulate on the glass door. This method of burning should be used only after
operating the MONACO with the air control opened to produce a hot fire for about an hour or
at medium pace for at least 2 hours. Slow combustion can be used at night in order to reduce
the heat output and to prolong the burn. The refuelling interval time will be between 6-8
hours.
3.2.8 Smoking − Causes and Troubleshooting
To reduce the likelihood of smoking when opening the door, set the combustion air controls
to the right (accelerated) before opening the door. Your fireplace has been designed and tested
to provide smoke free operation. Occasionally, there may be a small amount of smoking upon
lighting the fire, until the chimney heats up but this should not continue. If the fireplace
continues to smoke it is probably for one of the following reasons:
A. 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 fresh air kit. When operating the MONACO, open a nearby
window temporarily to check if there is adequate air supply replacement. If opening a
window solves the problem, the house is under negative pressure.
B. 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.

10
C. Wet wood
Wet or tarred wood will smoulder and smoke instead of burning properly.
D. Dirty or blocked chimney
Check to make sure the chimney is clear and clean.
E. Chimney not long enough
The minimum system height is 15 feet (4.6m). The chimney must extend at least 3 feet
(915 mm) above its point of contact with the roof and at least 2 feet (0.6 m) higher than
any roof or wall within 10 feet (3 m) of it. When installed with offsets, the minimum
system height is 15 feet (4.6 m) to 17 feet (5.2 m) as per Table 1. Additional height will
increase draught and will decrease the tendency to smoke. If only the minimum chimney
height is installed, operating conditions must be optimal (interior chimney, minimum
height of 18” before any offset, etc.).
F. Poor chimney draft
With no fire, there should be sufficient draught to exhaust cigarette smoke introduced
under the baffle. Chimneys installed against an outside wall without protection may
generate back draught 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 draught is sufficient, then start the fire.
IMPORTANT NOTES
A. Do not block the hot air vents to the fireplace as this will cause the fireplace to overheat.
B. Never start a fire using gasoline, kerosene, charcoal lighter fluid or any other combustible
liquid.
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 abuse the unit by burning paper, or cardboard or construction material such as
pressed wood, plywood or lumber.
F. Do not allow the wood to smoulder or burn without flame, since this will produce
excessive creosote in the unit.

11
3.3 MAINTAINING YOUR MONACO
3.3.1 Creosote – Formation and need for removal
When wood is burned slowly without a flame, it produces tar and other organic vapours
which combine with expelled moisture to form creosote. The creosote vapors condense in ;
the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue
accumulates on the flue lining. When ignited this creosote makes an extremely hot fire.
The chimney shall be inspected at least twice a year during the heating season to determine
when a creosote build-up has occurred.
When creosote has accumulated it shall be removed to reduce the risk of a chimney fire.
3.3.2 Chimney Maintenance
Regular chimney inspection and maintenance combined with proper operation will prevent
chimney fires. Keep your chimney clean. Do not allow more than 1/16″creosote build up in
your chimney. The amount of creosote will depend on variables such as frequency of use and
type of fire. We recommend that you:
A. Initially inspect the chimney system weekly. From this, you will learn how often it
will be necessary to clean your chimney.
B. Have your chimney cleaned by a qualified chimney sweep. If you wish to clean it
yourself, we recommend using a stiff plastic or non-metallic brush. If a metal brush is
used, its size should be slightly smaller than the flue to avoid damaging the chimney.
Do not use a brush that will scratch the stainless steel interior of the chimney.
C. Do not expect chemical cleaners to keep your chimney clean. The rain cap can be
removed for inspection and/or cleaning of the chimney.
3.3.3 Top Baffle Removal Prior to Cleaning the Chimney
Before starting to clean your chimney, we recommend that you remove the top baffle to avoid
creosote dust collection at the top of the baffle. Follow these steps to set the top baffle out of
the way:
1. Remove the front air tube by pulling out the cutter pin on the side of the tube. They are
located at the top, underneath the baffle.
2. Lift the baffle and slide it out of the fireplace. You now have access to the chimney.

12
Figure 2
3.3.4 Dealing with a Chimney Fire
Regular chimney maintenance and inspection can prevent chimney fires. If you have a
chimney fire, follow these steps:
1. Close the fireplace door and the combustion air controls;
2. Alert your family of the possible danger;
3. If you require assistance, alert your fire department;
4. If possible, use a dry chemical fire extinguisher, baking soda or sand to control the fire.
Do not use water as it may cause a dangerous steam explosion;
5. Check outside to ensure that sparks and hot embers coming out of the chimney are not
igniting the roof;
6. Do not use the fireplace again until your chimney and fireplace have been inspected by a
qualified chimney sweep or a Fire Department Inspector;
3.3.5 Plated Finish Maintenance
Use a glass cleaner and a soft cloth to polish the plated finish on the door frame. Do not use
abrasives such as steel wool, steel pads or an abrasive polish for they may scratch the finish.

3.3.6 Disposal of Ashes
Do not attempt to clean the fireplace when the unit is hot. Ashes should be placed in a metal
container with a tight fitting lid. The closed container of ashes should be placed on a non-
combustible floor or on the ground, well away from combustible materials pending final
disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed they
should be retained in the closed container until all cinders have thoroughly cooled. Do not
attempt to clean the stove when the unit is hot.
3.3.7 Refractory Replacement
The intense heat of the fire will normally cause hairline cracks in the refractory. These cracks
can be minimized by proper curing as described in “First Fires”. They will not normally
diminish the effectiveness of the refractory. If large cracks develop, then the refractory should
be replaced. To replace the refractory bricks, follow these steps:
1. Remove the left side bricks
2. Remove the right side bricks
3. Remove the back bricks
4. Remove the two floor bricks
To install the new bricks, follow the
above steps in reverse.

3.3.8 Glass Care – Replacement
The glass used for the MONACO is a high temperature ceramic glass (1400º F). Do not abuse
the glass door by striking or slamming shut. If the glass breaks, it must be replaced with an
identical ceramic glass. Tempered glass or ordinary glass will now withstand the high
temperatures of the MONACO. Replacement glass should be purchased from a FLAME
dealer (see “Replacement Parts”, in Section 7 – APPENDIX). Do not operate the unit with a
cracked or broken glass.
3.3.9 Glass Care – Cleaning
The MONACO is designed to keep the glass clean under normal operating conditions. If the
MONACO is operated continuously with the combustion air controls closed, the glass will
tend to get dirty unless the fuel, firebox and glass are maintained at hot. To clean the glass,

14
there are a number of specially designed cleaners. Your authorized FLAME dealer can
recommend a suitable cleaner which is available in your area. Regular household glass
cleaners will not clean creosote. Do not use abrasives such as steel pads, steel wool or oven
cleaner as they will scratch the glass. Only wash when the stove is cold.
3.3.10 Gasket Replacement
Remove the doors from the unit and lay them on a clean, unabrasive surface. To replace the
gasket around the door frame, first remove the old gasket and adhesive. Make sure that the
surface is totally clean before applying new adhesive (a high temperature silicone caulking
rated for at least 500ºF, 260ºC, is suitable) or adhesion problems may result. Apply the
adhesive inside the door groove (gasket channel) and install the new gasket with a gentle
pressure. Let dry for at least 24 hours. To replace the glass gasket, simply remove the glass
retainers holding the glass to the door frame. Remove the glass and peel off the gasket
surrounding it. Replace it by a new, self-adhesive glass gasket. The proper replacement
gaskets are available from your FLAME dealer in the following dimensions:
Gasket Length Dimensions
Around each glass 51 ½" (131 cm) U SHAPE
On each door frame 41 ¼" (105 cm) Flat ¼" x ½"
Along the door joint 14" (36 cm) Flat ¼" x ½"

3.4 FIREPLACE INSTALLATION
3.4.1 Locating the MONACO
A. The best location to install your fireplace is determined by considering the location of
windows, doors, and the traffic flow in the room where the fireplace is located, allowing
space in front of the unit for the heart extension and the mantel, and taking into
consideration the location of the hot air ducts (optional), outside air kit and chimney. If
possible, you should choose a location where the chimney will pass through the house
without cutting floor or roof rafters.
B. Usually, no additional floor support is needed for the fireplace. The adequacy of the floor
can be checked by first estimating the weight of the fireplace system. Weights are given in
the appendix. Next, measure the area occupied by the fireplace which is normally 36" ×
26". Note the floor construction and consult your local building code to determine if
additional support is needed.
C. The MONACO may be installed directly on the floor or on a raised base (for proper
guidelines, refer to “Heart Extension Requirements”) and a minimum of 7 feet (2.15 m)
measured from the base of the appliance to the ceiling is required. The hearth extension is
to be installed only as illustrated in the drawing below.

16
3.4.2 Heart Extension Requirements
The MONACO may be installed directly on a combustible floor; however, the combustible
floor in front of the fireplace must be covered with a non-combustible material (tile, marble,
stone, etc.). The hearth extension floor area shall extend at least 16" in front and at least 8" on
each side of the fireplace opening. (see figure 4). The floor protector in front of the fireplace
must have a R value of 1.53 or greater.
Convert specification to R-value:

3.4.3 Framing, Facing, Mantel, and Combustible Shelf
The construction of the framing, facing, and mantel must be in accordance with the standards
and the following illustrations (figures 4 to 11):
A. Frame the fireplace using 2" × 3" or heavier lumber.
B. WARNING:Combustible framing material cannot be used in the space directly above the
fireplace, except for the studs above the facing that support the facing material and
mantel. This area must remain empty for a height of 7′(2,15 m) measured from the base
of the appliance.
C. Frame the fireplace with vertical studs at the sides of the fireplace running from floor to
ceiling (see figure 6). Position the studs back from the front edge of the fireplace, a space
the thickness of the facing material so that the facing can be installed flush with the
fireplace facing (within limitations of figure 11). Frame headers between the vertical studs
only as follows:

17
−Place 2" × 3" or 2" × 4" headers, only along the upper part of the front, side and back
faces. Do not put wood or any combustible material within the area above the fireplace
except on the front facing.
−Place headers only as required to support the facing and mantel.
D. WARNING: DO NOT PACK REQUIRED AIR SPACES WITH INSULATION
OR OTHER MATERIALS.
THE FIREPLACE MUST NOT BE IN CONTACT WITH ANY INSULATION
OR LOOSE FILLING MATERIAL. COVER THE INSULATION WITH
GYPROC PANELS AROUND THE FIREPLACE.
