The first 5 or 6 fires should be small fires of
short duration (about 30 to 60 minutes). This
will help cure the refractory bricks. Ashes that

intense heat. The first fires may produce slight
smoking and some odor due to drying of the
paintandsteelandanydustaccumulatedonthe
fireplace will burn off at this time. It may set off
a smoke alarm located in the same room. For
this reason the room should be well ventilated
for the first few fires.
When the catalyst light-off conditions are
achieved, the combustor will keep on going
until it runsoutofsmoke. Notethatthe catalyst
does not need to be glowing to be working, it
can work very well at temperatures well below
the 538° C (1000° F) level at which it will begin
to glow. The best way to see if the catalyst is
active is to take a look at what is coming out
of the chimney. If the catalytic combustor is
working you will see some white water vapor
coming out, compared to a more brown/gray
smokewhentheby-passisopened. Donotburn
any chemical chimney cleaner; it can make the
catalyst inactive.
OPERATING THE FIREPLACE
Fuel
The Villa Vista™ fireplace is designed to work
best when fuelled with seasoned cordwood.
Hardwoodsarepreferredtosoftwoodssincethe
energycontentofwoodisrelativetoitsdensity.
Hardwoods will result in a longer burning fire
and less frequent refuelling.
A moisture content of 15% to 20% (seasoned)
is recommended. Excessively wet wood will
be difficult to burn and will result in lower ef-
ficiency, increased creosoting and plugging of
the catalytic combustor. Excessively dry wood
willburnwellbutwillalsohavehigheremissions
and shorter burning time.
Catalytic Combustor
The Villa Vista fireplace is equipped with a
catalytic combustor. Unburned by-products of
the wood fire are burned at lower temperatures
as they pass through the combustor resulting
in less pollution, reduced creosote and higher
efficiency. In order to have the catalyst work-
ing, temperatures of the flue gases entering
the combustor have to be higher than 260° C
(500° F). That is why the unit is equipped with
a by-pass damper that allows the draft air to
by-pass the catalytic combustor. Opening the
by-pass damper control increases the draft
allowing the unit to achieve proper operating
temperatures during a cold start-up. It also
provides more draft to prevent smoke spillage
when the door is opened.
Combustion Control
There is no flue damper in the Villa Vista fire-
place. As is common with air tight stoves, the
combustion air damper controls the air enter-
ing the firebox. This allows for a more precise
control of the fire. The combustion air damper
knob is located on the left of the bottom louver
(Figure1). Itisopenedwhenmovedcompletely
to the left. This control should be in the closed
position when the fireplace is not in use. This
will minimize air leakage up the chimney. The
combustionaircontrolandtheby-passdamper
control must be opened before opening the
door to minimize the possibility of back draft
coming into the room.
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
can shorten the life of the catalytic combustor.

Intensefiringwiththesematerialsmayoverheat
the fireplace, causing damage to the unit, a fire
or even possibly igniting a chimney fire if the
chimney is creosoted.
Overheating the unit above 1000° C (1800º F)
is harmful for the catalytic combustor, it can
damage the catalyst coating and can cause
cracking of the substrate. Looking through
the upper louvers, if the top of the firebox is
glowing, the unit is overheating.
First Fires
Before using the fireplace make sure to remove
the plastic wrapping on the doors. Remove all
remaining glue from labels with mild soap.
Gold and Nickel plated doors must be cleaned
and free of fingerprints.

Step 2. Open the air control fully and pull the
by-pass damper control towards you to put it
in the OPEN position. Light the newspaper.
Leave the door open until the fire is well es-
tablished.
Accelerated Combustion
Slow Combustion
When the air combustion damper is almost
closed, the fireplace is in a slow combustion
phase (see Figure 4). 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).
Always set the damper so that flames are
visible , that way you maintain a good clean
combustion process.
The maximum heat output for the Villa Vista™
fireplace is achieved by burning with the com-
bustion air damper opened (see Figure 2). By
thismethod,the VillaVistafireplacecanproduce
up to 70,000 BTU of heat per hour. However, it
willbenecessarytoreloadwithwoodeveryone
or two hours. This is the least efficient method
of burning the Villa Vista fireplace.
Step 3. Once the kindling fire is well estab-
lished, add increasingly larger pieces of cord-
wooduntilthefireisactivelyburning. Closethe
door and maintain an accelerated combustion
air set up in order to achieve combustor light-
off conditions.
Step 4. Whenthefireisburningwell,closethe
by-passdampercontrolbypushingthecontrol
rod in. It takes about 15 – 30 minutes with
the by-pass opened to reach proper light-off
temperatures for the catalytic combustor.
Step 5. Set the air control at the desired set-
ting.
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 get started easily.
Figure 2
Figure 4
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
and catalytic combustor.
This method of burning should be used only
after operating the Villa Vista fireplace with the
aircontrolopenedtoproduceahotfireforabout
an hour. Slow combustion can be used at night
in order to reduce the heat output and prolong
the burn. The loading time will be between 6-10
hours. Be aware that the glass will get dirty
using this setting.
Refuelling for Best Performance
(see Figure 5)
To refuel the Villa Vista 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):
Medium Combustion
This is the recommended mode of operating
the Villa Vista fireplace 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 damper must be
3/4" closed (see Figure 3). The precise setting
willdependonmanyfactors,includingchimney
length and the moisture content of the wood.
Starting And Maintaining a Fire

3. Do not expect chemical cleaners to keep
your chimney clean. The rain cap can be
removed for inspection and/or cleaning of
the chimney. Using gloves, firmly grip the
lower portion of the rain cap. Turn the cap
1/8 of a turn counter-clockwise and lift it
off the chimney.
Step 3. Keep the combustion air damper and
the by-pass damper opened for 10 minutes
before closing it. It will ensure sufficient tem-
peratures for combustor light-off.
Then, hold it in the upper part of the firebox
towarmupthechimney. Waituntilthedraft
is sufficient, then start the fire.

unit is still hot (Some burning fuel remaining
or a glowing combustor)
Important Notes
1. Do not block the hot air vents of the fire-
place as this will cause the fireplace to
overheat.
Dealing With A Chimney Fire
Step 1. Open the by-pass and air controls
fully.
2. Never start a fire using gasoline, kero-
sene, charcoal lighter fluid or any other
combustible liquid.
3. Do not burn coal. The sulphur in coal will
corrode the firebox.
4. Do not burn driftwood which has been
in the ocean or salt water. The salt will
corrode the firebox and chimney.
5. Donotoperatetheunitwiththedoorpartly
open since this may cause smoke to be
drawn into the room.
6. Do not burn wood in the area in front of
the log retainers.
7. Do not abuse the unit by burning paper,
or cardboard or construction material
such as pressed wood, plywood or
lumber.
8. Donotallowthewoodtosmoulderorburn
without flame, since this will produce
excessive creosote in the unit.
Regular chimney maintenance and inspection
canpreventchimneyfires. Ifyouhaveachimney
fire, follow these steps:
Step 2. Open the door approximately 1 inch,
wait five seconds until the draft is stable and
then open it completely. Load the fuel, close
the door and by-pass (temperatures within the
firebox should be enough to maintain catalytic
operation)
1. Close the fireplace doors and the combus-
tion air damper.
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 extin-
guisher, baking soda or sand to control the
fire. Do not use water as it may cause a
dangerous steam explosion.
5. Checkoutsidetoensurethatsparksandhot
embers coming out of the chimney are not
igniting the roof.
Smoking – Causes and Troubleshooting
To reduce the likelihood of smoking when
opening the doors, set the air damper to the
“accelerated combustion” position and open
the by-pass damper before opening the doors.
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 does
continue to smoke, it is probably for one of the
following reasons:
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.
MAINTAINING YOUR FIREPLACE
Creosote
1. The door is partly open
Open the door fully.
Catalytic Combustor
2. 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. When operating the Villa Vista fire-
place, open a nearby window temporarily
to check if there is adequate air replace-
ment.
When wood is burned slowly, it produces tar
and other organic vapors which combine with
expelledmoisturetoformablackdepositcalled
creosote which accumulates on the flue lining.
Whenignited,thiscreosotemakesanextremely
hot fire. If the creosote accumulation is large,
a creosote fire in the chimney can damage the
chimney and overheat the surrounding wood
framing. Creosote formation in a chimney can
be minimized by making small hot fires rather
than slow burning, smouldering fires and by
proper refuelling techniques.
The Villa Vista™ fireplace is designed with a
catalyticcombustorwhichwillreducepollution
emissions and creosote build up while improv-
ing thermal efficiency. In order to optimize and
maintain the combustor performance, it is im-
portant to visually check the combustor at least
3 times during the heating season to determine
if physical degradation has occurred.
3. 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.
Catalyticcombustorsrequirelittlemaintenance.
Cleaning the combustor once a year, preferably
when your flue system is serviced, is sufficient
for most users.
Chimney Maintenance
4. Wet wood

The Villa Vista fireplace is designed to keep
the glass clean under normal operating condi-
tions. If the Villa Vista fireplace is operated
continuously with the combustion air damper
closed, the glass will tend to get dirty unless
the fuel, firebox and glass are maintained at
hot temperatures (see “Refuelling For Best
Performance”). To clean the glass, there are a
number of specially designed cleaners. Your

2. 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 on Page 25. Next, measure the area
occupied by the fireplace which is normally
38" X 24-1/2". Note the floor construction and
consult your local building code to determine
if additional support is needed.

Hearth Extension Requirements
The Villa Vista™ fireplace may be installed
directly on a combustible floor. The supplied
safety metal strip must be positioned as fol-
lows: One half under the front of the fireplace
and the other half must extend on the floor
over which the hearth extension will be built
(see Figure 10A).
Mantel
* The safety metal strip must cover the entire
width of the fireplace
The combustible floor in front of the fireplace
mustbecoveredwithanon-combustiblemate-
rial (tile, marble, stone, etc). See Figure 10B.

Non combustible material
If this fireplace is being installed in a cold
climate, it is especially important to seal all
cracks around the fireplace and wherever cold
air could enter the room with noncombustible
material.
Figure 10B
Also, the outside air inlet duct should be wrapped with noncombustible insulation to minimize
the formation of condensation. Do not place insulation materials directly against the chimney
sections. We recommend that you use the insulated wall radiation shield since it will maintain the
home’s thermal barrier. AC chimney is NOT recommended in very cold climates (in areas with
temperatures below 0° F (-18° C).

OUTSIDE AIR KIT
OUTSIDE AIR CONNECTION
ALUMINIUM TAPE
During operation, the fireplace requires fresh
air for combustion and draws air from outside
the house. It may starve other fuel burning
appliances such as gas or oil furnaces. As
well, exhaust fans may compete for air, caus-
ing negative pressure in the house, resulting in
smoke entering the house from the fireplace.
This situation is aggravated in modern airtight
houses. To overcome this potential problem,
we require the installation of an outside air
assembly.

1. If possible, install an interior chimney as it
will provide better performance. In areas
with continuous temperatures below 0° F
(18° C), the use of an exterior chimney in-
creasesthelikelihoodofoperatingproblems
such as low draft, high rate of creosoting,
and poor start-up characteristics. Exterior
chimneys are also prone to down-drafting
and flow reversal. Installations, which are
located on lower floors in the house, such
as in a basement, in combination with out-
side chimney, are especially prone to flow
reversal.

CHIMNEY CHASE AND MULTIPLE TERMINA-
TIONS
CHIMNEY SUPPORT INSTALLATION
Universal Roof Support
Forthepurposeofthismanual,achimneychase
is considered a part of the chimney system
rather than part of a building. The termination
must be placed a minimum of 18" (460 mm)
above the chase.
NOTE: For the ACBI chimney, a universal sec-
tion must be used every 20 feet (6 m) instead
of the universal roof support (ST).
This support has two possible uses:
1. For ASHT+ it must be used on a roof to
support the chimney.
Forroofsupportinstallation,refertotheinstruc-
tions provided with the support.
For installations where more than one chimney
is located in the same chase or within the same
area, we suggest that their terminations be
separatedbyatleast16"(410mm)horizontally,
and 18" (460 mm) vertically. This separation is
to prevent smoke migration from one chimney
to another (see Figure 29).
2. It may be used on a floor, ceiling or roof
above an offset to support the chimney
above the offset.
Universal Offset Support
This support is used to support the chimney
above an offset. Or it may be used on the wall
to support the chimney. The maximum heights
are given in Table 6. For offset support instal-
lation, refer to the instructions provided with
the support.
3. It may be used on a floor, ceiling or roof
above as a supplementary support when
the chimney height exceeds 15 feet (4.6
m).
CHIMNEY ADAPTOR (S2100+)
Thefireplaceisnormallysuppliedwithachimney
adaptor suitable for the ASHT+ chimney. If you
want to install a S2100+ chimney, an adaptor is
availible (7UCA) (see Figure 30). If installing
ACBI,adaptorH3805(ACBISB)oroffsetadaptor
H3806 (ACBISB30) is required.

within the masonry chimney.
Installation:
Figure 31
The chimney must be relined with a stainless
steellinermodelTUBINOXorPROjETSSofthe
same diameter as the outlet of the fireplace.
Note: 45° offsets allowed in Canada only.
A. SelecttheASHT+lengththatwillfitbetween
the elbow and the liner so that it will slide
at least 2" over the liner section. (You may
need to cut the liner for a better fit).
B. Take that section and the BISUMA30
cover and slide it over the liner. Make
sure you have enough opening to be
able to install the ASHT+ elbow without
difficulty.
For connection at a 30º angle, a special con-
nector (BISPMA30) must be used to connect
the liner to the insulated chimney.
3- Increase the size of the hole until a 45º
or 30º TUBINOX liner elbow can be easily
slipped through.
4- Slide the liner down from the top of the
masonry chimney until you reach the hole
level.
5- Slip through the hole a 45° or 30° liner
elbow and connect it to the liner.
6- Add a small liner section to the liner elbow
which will allow the liner to extend at least
12”(measuredatthetopoftheliner)from
the masonry chimney.
*IMPORTANTNOTE-Theuseofa45ºconnec-
tor (BISPMA) is approved for use in Canada
ONLY. Installations in the USA must use the
30º connector (BISPMA30).
C. Install the 45° or 30° elbow on the fire-
place.
See Figure 31 for typical installation.
D. Slide the length section back down on the
elbow and twist lock the two together.
E. Pull the cover down over the length and
install the insulation pad over the liner; be
careful to cover the liner completely.
F. Slide back the cover over the insulation
andfixitinplaceusingthe3metalscrews

Follow these steps:
1- Position the fireplace in its location. Tem-
porarilyinstalltheASHT+elbowonthetop
of the fireplace and, using a level, mark
with an oval the location where the flue
liner will enter the masonry chimney.
2- In the middle of the oval, drill a hole in the
masonry chimney at 45° or 30°.
7- Sealtheopeningaroundthelinerwithhigh
temperature refractory cement.
8- The next steps must be done in the fol-
lowing order :
