INTRODUCTION
INSTALLATION
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 install your 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 the 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 fire.
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'F. In the USA, the floor protecior must extend 8" beyond each side of the flue loading door
and 16" to the front. In Canada, the floor protector must extend 8" (200mm) beyond each side and the back of the appliance
and 18" (450mm) to the front. (See fig. 1)
16"-USA
18" (450mm) Canada
Fig. 1

. 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.,
plastics, riirood paper products, etc) gre combustible and must not be used. The floor protection specified includes some form
bf thermal desigriatioh such as R-value (thermal resistance) or k-factor (thermal conductivity).
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: n =f x f
iii. K-factor is given with a required thickness (T) in inches:n =1fu x f
iv. r-factor is given with a required thickness (T) in inches: R = r x T
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 protector should be 3/4-inch thick material with a k-factor of 0.84. The proposed alternate is
4" bricit with an i-factor of 0.2 over 1/8" mineral board with a k-factor of 0.29.
Step (a): Use formula above to convert specification to R-value.
R= *" t =*nx 0.75 = 0.8e3
Step (b): Calculate R of proposed system.
- 4" brick of r = 0.2, therefore:
Rbrick=0.2x4=0.431
1/8" mineral board of k = 0.29, therefore
Rmineralboard = "tnx 0.125 = 0.431
Rtotal = Rbrick+ Rmineralboard= 0.8 + 0.431 = l'23I
Step (c): Compare proposed system Rtotal of 1.231 to specified R of 0.893. Since proposed system Rtotal is greater than required,
the system is acceptable.

Installation Clearances
It is extremely important that you respect required installation distances and that you respect local installation regulations.
This is for yorir safbty! The manufacturer is not iesponsible for the product, if it is not iristalled following these recommendations.
These clearances may only be reduced by means approved by the regulatory authority.
A combustible surface is anything that can burn (i.e. sheet rock, wallpaper, wood, fabrics etc.) These surfaces are not limited
to those that are visible anil also include materials that are behind non-combustible materials. If you are not sure of the
combustible nature of a material, consult your local fire o{Iicials.

'himney Connection
The chimney connector is a single walled pipe used to connect the stove to the chimney. For use with the appliance the
chimney connector MUST be 6" in diameter, with a minimum thickness of 24 gauge black steel or 26 gauge blued steel.
Aluminium and galvanized steel pipe is not acceptable for use with the appliance. These materials cannot withstand the
extreme temperatures of a wood fire and can give off toxic fumes when heated.
Do not use the connector pipe as a chimney.
Each chimney connector or stovepipe section must be installed to the stove flue collar and to each other with the male
(crimped) end toward the stove. See fig 2.
This prevents any amount of condensed or liquid creosote from running down the outside of the pipe or the stovetop. All
joints, including the flue collar connection must be secured with three sheet metal screws to ensure that the sections do not
separate.
For the best performance the chimney connector should be as short and direct as possible, with no more than two 90 elbows.
The maximum horizontal run is 36" and a recommended total length of stovepipe should not exceed 10 feet. Always slope
horizontal runs upward l+" per foot toward the chimney.
No part of the chimney connector may pass through an attic or roof space, closet or other concealed space, or through a
floor ceiling. All sections of the chimney connectors must be accessible for cleaning. Where passage through a wall or parti'tion
of combustible construction is desired, the installation must conform with NFPA 2Il or CAN/CSA-8365, and is also addressed
in this manual.

Factory Built Chimney
When a metal prefabricated chimney is used, BOSCA's
installation inshuctions must be followed. You must also purchase
(from an authorized retailer) and install the ceiling support
package or wall pass{hrough and'T" section package, firestops
(where needed), insulation shield, roof flashing, chimney cap,
etc. Maintain proper clearance to the strucflrre as recommended
bv BOSCA. The-chimne.y must be the required height above
tlie roof or other obstrlctions for safety and proper draft
operation. (See fig.3)
Masonry Chimney
Ensure that a masonry chimne.y meets the minimum standards
of the National Fire Piotection Association (NFPA) by having it
inspected by a professional. Make sure there are no cracks,
loose mortaror other signs of deterioration and blockage. Have
the chimney cleaned before the stove is installed and operated.
When conirecting the stove through a combustible wallto a
masonry chimnei, special methods are needed (See fig. 4).

MOBILE HOME INSTALLATION
Follow these special requirements for installing your stove in a
mobile home:
- An outside air inlet must be provided for combustion and must
remain clear of leaves, debiis ice and/or snow. It must be
unrestricted while unit is in use to prevent room air starvation
which can cause smoke spillage andbn inability to maintain a fire.
Smoke spillage can also set off smoke alarms.
- Outside air inlet installation: Use a BOSCA connector (see
Reolacement Parts. ps. l6) which you can purchase from an
ofdcial BOSCA deaiel a 4" single invall aluminum flex pipe of
appropriate length for installation, a rain cap and two 4" clamps,
avaita6te at youilocal hardware retailer'
To install the outside air inlet, place the connector over through
the hole behind the heater, connect the flex pipe and altach it
securelv with one of the two clamps. The other side of the flex
pipe sfiould be connected on the outside to the rain cap'
- Permanentlv attach the stove to your mobile home's floor. The
pedestal -urib" bolted to the flodr. Use /+" holes in the base to
bolt down the stove.
- Regulation requires that unit-must be grounded. Attach a piece
of #f,8 cooper wire, at least 18" in length from the stove to the
'hassis of the mobile home.
- Stove must be installed with an approved Ut103 HT ventilated
chimnev connector, Ut103 HT chimney and terminal cap with
spark airestor. 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.
- Use slicone to create an effective vapor barrier at the location
where the chimney or other componenfs penetrates to the exterior
of the structure.
- Follow the chimney and chimney connector manufacturer's
instructions when installing the flu-e system for use in mobile
homes.

OPERATING AND LIGHTING INSTRUCTIONS
your GOLD 400's performance depends largely on how it is operated. Please read this section carefully before lighting your
first fire.
When vou lisht vour first fire, the stove will emit some smoke and the smell of paint. This is normal. Open the windows to
vent th6 rooir attd eliminate the smell .
Before lighting your stove, ensure that the baffle is correctly installed. For baffle installation instructions, see page 12
(Maintenance).
Before lighting your stove, ensure that the refractory bricks are correctly installed. For refractory bricks installation instructions,
see page 14 fMaintenance).

place the Air Controlin the desired position.

MAINTENANCE
The Gold 400 requires little maintenance. However, there are parts of your stove that should be checked periodically.
Baffle
Your Gold 400 stove has a removeable baffle that needs to be replaced periodically, depending on the stove's use.
When the baffle needs to be removed, make sure that the stove i^s cold liefore putiing your ha"nds into the firebox.
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.
To obtain good combustion during the whole night, proceed as follows:
! Form a base of live coals at the bottom of the firebox.
U load the stove completely with dry firewood.
I When flames begin to appi:ar on the logs move the Air Control to MEDIUM.
How do I load my stove after a prolonged combustion?
I At the end of a long combustion cycle, reestablish the fire adding a few small split logs and small
logs.
_[ O. .pen the door of the ashtray for 5 minutes or until the split logs and small logs are alight.
! {llow- the temperature o_f tlre stove to recuperat-e belore adding i-arger ldgs.
U Reload the stove according to the description above.
Remove the rear panel, pulling it towards you.
Remove the air pipe protector, sliding it upwards.
Release the bolts that fix the baffle to the firebox, using a 10mm wrench.
Once the bolts are loose, slide the baflle down as indicated in figure 8. Carefull.y, angle the baffle on one side
to make sure it doesn't accidentally fall, as this may result in serioirs injury (fig. 9f
To place the new baffle in its proper position, insert it into the firebox,
in such a way that it rests on the support brackets installed specially for
the baffle. Make sure that the baffle air pipe is inserted completely-into
the hole in the back of the firebox (Fig 10) and the bolts have gone
through the holes to the outside of the-hxebox.
Bolt the baffle to the rear wall of the firebox from the outside.
Place the air pipe protector back in its normal position.
Place the rear panel back in place, be sure that it is correctly set and
bolt it.

NOTE: To open the ashbin door, you have to use the steel handle provided with your stove.
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. 7
Replace the glass as follows:
- Make sure that the fire is completely extinguished and the stove is cold.
- Protect your hands with gloves thai are appropriate for this type of work.
- Removti the front door, c-arefully pushing it upward (fig 7).
- Place the door on a flat surface.
- Unscrew the bolts that hold down the stainless-steel frame on the stove door.

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 Oflicial BOSCA Dealer.
Glass Cleaning
One of the more attractive 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 Controi settiilg on "Low" Fosition. Use only dry wood. Store it adequately, and keep the
Air Control at the "Medium" position.
- Clean the glass periodically ririttr a commercial stove glass cleaner, waiting until the glass is completely cold before
cleaning.

)oors Gasket Replacement
STAINLESS STEET FRAME
Your GOLD 400 uses rope{ype 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 effectiveness 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 * MD .500 G Black Fiberglass Rope or equivalent.
Remove the existing gasket.
Clean the stainless steel channel.
Measure the length of the rope by laying it out in the stainless steel channel.
Remove the rope from the channel and cut it to the appropriate length. Take care to ensure that the rope does not
unravel.
Place a bead of high-temperature adhesive in the clean stainless-steelchannel.
Beginning at one of the ends, press the gasket into the stainless-steel channel interior.
Before cutting, make sure the rope ends properly meet. Do not overlap rope ends.
Firmly press the rope en make sure it properly seats into the stainless-steel channel interior.
Clean any excess adhesive and allow to dry.
