INTRODUCTION
INSTALLATION
We would like to congratulate you for selecting our BOSCA CLASSIC 450. By purchasing a BOSCA product, you receive
the advantage of the"strength,-guarantee andthe more, than 20 yeals expeiience BOSCA has in producing stoves and
heaters equip--ped with seconldary-air combustion system, which enable efficient consumption of the wood, as well as minimum
impact to the general environment.
Bosca Chile S.A. is the leading company in the production of wood stoves in Chile, with more than 250,000 stoves sold and
there are BOSCA products installed in hiluses in Spain, Portugal, fugentina, Uruguay, Ecuador, and Mexico.-ln the prfrduction
of our stoves, we irse only the finest materials. Ttiis, along wTth the experiencebf the members of our staff, means for you a
product of high quality and dependability.
The BOSCA CLASSIC 450 is a clean burning EPA certified, non-catalytic wood burning stove with 3,6 grams per hour
particulate.
The BOSCA CTASSIC 450 has been tested and listed by OMNI-Test Laboratories,lnc. The test standards are U11482 and ULC
s627.
Please read this entire manualbefore you install and use your BOSCA CLASSIC 450. The purpose of this manual is to familiarize
you with your CLASSIC 450's safe initallation, operation and maintenance. It contains information that will be useful, so save
it for future reference.
For your ultimate safety and the proper function of your stove, it should be installed in accordance with the instructions of
this Manual.
The first step is to decide where is the most appropriate place to installyour stove.
It is important to install the stove in an area with adequate air circulation and flow. This allows the warm air to more easily
reach ihe intended rooms. Additionally, your stove's placement should enable, and not be an obstacle to free movement
of people, especially children.
Your stove and chimney connector must be far enough from combustible materials to meet all clearance requirements.
The floor
One of the main necessary precautions when installing a wood stove is to leave sufficient space between the stove (top, sides,
back, front, and under stove pipes) and any other material that can catch fre.
If the stove is to be installed on a combustible floor, it must be placed on an approved L/2" (13mm) non-combustible hearth
pad with k = 0.84 BTU/in ft2 hr oF. In the USA, the floor proteclor must extenil 8" beyond ea,ch side of the flue loading door
hnd 16" to the front. In Canada, the floor protector mu s[extend 8" (200mm) beyond each side and the back of the appliance
and 18" (450mm) to the front. (See fig. 1)

I a rear vent installation the floor protection must also extend under the stovepipe a minimum of 2" (50mm) beyond either
side of the pipe.
How to determine if alternate floor protection materials are acceptable.
All floor protection must be non-combustible (i.e.,_metals, brick, stone, mineral fiber boards, etc.). Any organic materials (i.e.,
Pl.astics, w99d papel products, e_tc) gre combustible and must not be used. The floor protection specifiedincludes some form
of thermal designation such as R-value (thermal resistance) or k-factor (thermal condrictivity).
Procedure:
1. Convert specification to R-value:
i. R-value given - no conversion needed.
ii. k-factor is given with a required thickness (T) in inches:
iii. K-factor is given with a required thickness (T) in inches:
iv. r-factor is given with a required thickness (T) in inches:
n=f xr
n=*fu xr
R=rxT
2. Determine the R-value of the proposed alternate floor protector.
i. Use the formula in step (1) to convert values not expressed as "R".
ii. For multiple layers, add R-values of each layer to determine overall R-value.
If the overall R-value of the system is greater than the R-value of the specified floor protector, the alternate is acceptable.
Example:. The specified floor protecto^r..should be 3/4-inch thick material with a k-factor of 0.84. The proposed alternate is
4" brick with an r-factor of 0.2 over 1/8" mineral board with a k-factor of 0.2g.
Step (a): Use formula above to convert specification to R-value.
R= +" t =*+x 0.75 = 0.8e3
Step (b): Calculate R of proposed system.
4" brick of r = 0.2, therefore:
Rbrictr= 0.2 x 4 = 0.431
1/8" mineral board of k = 0.29, therefore
Rmineralboard = #n * O.LZS = O.43I
Rtotal = Rbrick + Rmineral board = 0.8 + 0.431 = I.23I
Step (c): Compare proposed system &otal of 1.231 to specified R of 0.893. Since proposed system Rtotat is greater than required,
the s.ystem is acceptable.

remain clear of leaves, debris ice and/or snow. It must be
unrestricted while unit is in use to prevent room air starvation
which can cause smoke spillage and an inability to maintain a fire.
Smoke spillage can also set off smoke alarms.
- Outside air inlet installation: Use a BOSCA connector (see
Replacement Parts, pg. l6) which you can purchase from an
official BOSCA dealer, a 4" single wall aluminum flex pipe of
appropriate length for installation, a rain cap and two 4" clamps,
available at your local hardware retailer.
To install the outside air inlet, place the connector over through
the hole behind the heater, connect the flex pipe and attach it
securely with one of the two clamps. The other side of the flex
pipe should be connected on the outside to the rain cap.
- Permanently attach the stove to your mobile home's floor. The
pedestal must be bolted to the floor. Use Y+" holes in the base to
bolt down the stove.
- Regulation requires that unit must be grounded. Attach a piece
f # o8 cooper wire, at least 18" in length from the stove to the
,rassis of the mobile home.
- Stove must be installed with an approved ULl03 HT ventilated
chimney connector, Utl03 HT chimney and terminal cap with
spark arrestor. Never use a single wall connector in a mobile
home installation.
- See clearances to combustibles on page 5 of this Manual or in
the Serial Number Label on the back of the stove.
- Follow the floor protections requirements detailed o n page 3.
- In Canada, this stove must be connected to a 6" factory-built
chimney conforming to CAN/ULC-629M.

OPERATING AND LTGHTING INSTRUCTIONS
Your CLASSIC 450's performance depends largely on how it is operated. Please read this section carefully before lighting
your first fire.
When you light your first fire, the stove will emit some smoke and the smell of paint. This is normal. Open the windows to
vent thb room and eliminate the smell .
Before lighting your stove, ensure that the baffle is conectly installed. For ba{fle installation instructions, se page 12 (Maintenance).
Before lighdng your stove, ensure that the refractory bricks are conectly installed. For refractory bricls installation instructions,
see page 14 fMaintenance).
[ighting
! Place crushed sheets of paper or firelighters in the center of the firebox.
I Place some kindling on top of the paper and some small split logs, preferably in a vertical position.
I Light the fire and close the door.
! Open the door of the ashtray and leave it this way for approximately 3 minutes or until the split logs are alight.
U Add the load of firewood, placing the lightest logs directly over the fire and the heavier ones on top of these.
t] Close the door of the firebox and maintain the door of the ashtray open for approximately 5 more minutes.
! Once the logs are alight, close the door and place the Air Control on HIGH for 20 minutes.
! When the stove reaches the operation temperature and there is sulficient draft, graduate the Air Control to the
desired position. It is recommendable to slowly adjust this command before graduating to the MEDIUM position
(prolonged combustion).
I You will find by experience how to best manage your stove to your liking. You must not expect an immediate reaction
from the fire when movingthe Air Control. The flame willnot intensify nor extinguish quickly as it would with liquid
or gas fuels. Solid fuels, like firewood, react slowly.
I If the fire is initiated as instructed, a good base is established for an effective combustion that is smokeless and that
does not pollute.

MAINTENANCE
The CLASSIC 450 requires little maintenance. However, there are parts of your stove that should be checked periodical$.
Baffle
Your CLASSIC 45O stove has a removeable balfle that needs to be replaced periodically, depending on the stove's use.
When the baffle needs to be removed, make sure that the stove is cold bdfore putiiiigyS"i6ifrai itii" tte'nreno".
To replace the baffle, you have to dismantle the rear panel of your stove (fig.7):
1) Release the 4 bolts located on the sides of the rear panel, using a 10mm wrench.
Remove the rear panel, pulling it towards you.
Release the bolts that fix the baffle to the firebox, using a 1Omm wrench.
Once the bolts are loose, slide the baffle down as indicated in figure 8. Carefully, angle the baffle on one side
to make sure it doesn't accidentally fall, as this may result in serio"us injury (fig. gf

To place the new baffle in its proper position, insert it into the firebox,
in such a way that it resr.s on the suppbrt brackel.s installed speciallv for
the baffle. Make sure that the baffle dir pipe is inserted completelv"into
the hole in the back of the firebox (Fig i0) and the bolts have gone
through the holes to the outside of theJixebox.
Bolt the baffle to the rear wall of the firebox from the outside.

Disposalof Ashes
Your unit's firebox has a grooved base, through which the ashes from the wood bumed automatically deposit into the ashbin.
When the ashbin is full, make sure that the stove and the ashes are cold (remember that the coals can remain hot for up to
36 hours) and place the ashes in a metal container with a tight fitting lid. The closed container of ashes should be placed
on a noncombustible floor or on the ground, well away from all 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.
Glass Replacements
The front glass is a ceramic glass, especially made for use in wood stoves, and should therefore not be marred by normal
use of the stove,
If for any reason the glass does break, it will be necessary to replace it. Never operate your stove with broken glass.
Fig. 11
Replace the glass as follows:
- Make sure that the fire is completely extinguished and the stove is cold.
- Protect your hands with gloves that are appropriate for this type of work.
- Removd the front door, carefully pushing it upward (fig 11).
- Place the door on a flat surface.
- Unscrew the bolts that hold down the stainless-steel frame on the stove door.
- Separate the door frame from the glass. The glass should be loose on the door, once the frame has been removed.
- Pla-ce a new sheet of glass on the tloor, reset the frame in its original position, then screw the frame in place on the
door.
- Reinstall the door, inserting the bottom part first, then the top part.
- Before lighting a new fire, ensure that the door is seated in its conect position.
Use only ceramic glass for use in wood stoves. Do not use other type of glass.
If the ceramic glass of your stove needs to be replaced, contact your Official BOSCA Dealer.
Glass Cleaning
One of the more attactive features of your stove is that you can actually enjoy seeing the fire. However, your view may be
obscured when the glass becomes dirty.
In order to minimize this, we recommend the following advice:
- The main cause of dirt spots on your glass is directly connected with the humidity content of the wood used, along
with maintaining the Aii Control setting on "Low" Position. Use only dry wood. Store it adequately, and keep the
Air Controlat the "Medium" position.
- Clean the glass periodically with a commercial stove glass cleaner, waiting until the glass is completely cold before
cleaning.

)oor Gasket Replacement
STAINLESS STEEL FRAME
Your CLASSIC 450 uses rope-type fiberglass gaskets at the interior of the front and ashtray doors to sealed it. After a time of
use, gaskets can become brittle and compressed, begin to lose their effectivehess and need to be replace.
To replace any gasket, be sure that the fire is out and the stove is cold and follow as is describe:
- Use Fil-Tec rM MD .500 G Black Fiberglass Rope or equivalent.
- Remove the existing gasket.

To replace the wood handle, check with your Oflicial BOSCA Dealer.
Creosote - Formation and need for removal
When wood is burned slowly, it produces tar and other organic vapors, 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 connector and chimney should be inspected at least every two months during the heating season to determine
if creosote b'uild up has occurred. "
If creosote has accumulated it should be removed to reduce the risk of a chimney fire.
