1. The installation of this stove must comply with your local building codes. Please observe

the clearance to combustible. Stove must be 27.6"(70 cm)-side, and 16" (40cm)-back, from

any combustible material, wall, wood, furniture, paper, etc. Note: Drywall faced with bricks

or stone should be consider a combustible surface.

2. Always connect this stove to a chimney and vent outside. This stove requires approved ma-

sonry or factory build 6" diameter UL 103 Type HT chimney, that is high enough to give

good draft.

3. Do NOT connect this stove to a chimney flue serving another appliance.

4. Be sure that your chimney is safely constructed and in good repair. Have chimney inspected

by the fire department or a qualified inspector.

5. Creosote or soot may build up in the chimney connector and chimney and may cause a

house or building fire. Inspect the chimney connector and chimney twice monthly during

the heating season and clean if necessary.

6. Burning any kind of fuel uses oxygen from the dwelling. Provide fresh air for proper com-

bustion from outside the house into the room where the stove is located.

THIS SOLID FUEL BURNING APPLIANCE.

MASONRY CHIMNEY

Before using an existing masonry chimney, clean the chimney, inspect the flue liner and make

any repair needed to be sure it is safe to use.

If connector stove pipe must go through a combustible wall before entering the masonry chim-

ney, consult a qualified mason or chimney dealer. The installation must conform to local fire

codes, and NFPA 211.

Do NOT connect this stove into the same chimney flue as the fireplace or flue from another

stove. If there is a cleanout opening in the base of the chimney, close it tightly.

UL LISTED CHIMNEY

Carefully follow chimney manufacturer's instructions. Us only a UL 103 Type HT Listed Resi-

dential Type and Building Heating Appliance Chimney. The top of the chimney must be at least

three (3) feet above the roof and be at least two (2) feet higher than any point of the roof within

ten (10) feet.

Chimney connector systems and clearances

Chimney connector shall not pass through attic or roof space, closet or similar concealed space, or a floor,

or ceiling. When passage through a wall, or partition of combustible is desired, the installation shall con-

form to CAN/CSA-B365, Installation Code for Solid-Fuel-Burning Appliances and Equipment:

APPLIANCE PLACEMENT

Have an authorized dealer install the appliance. If you install the appliance yourself, have your dealer review

your installation plans and/or installation.

OPERATION OF THE STOVE

1. Burn wood only. The wood should be natural, air dried (seasoned) for at least six (6)

months. Before lighting open draft, located on front left or right side of stove. Light wood

using paper, twigs, etc. NEVER USE ANY FLAMMABLE LIQUIDS OR GASOLINE

TO START OR FRESHEN UP A FIRE IN THE STOVE.

2. After the fire has been started, adjust the rate of burning by opening or closing the draft con-

trol.

3. Do NOT touch the stove after firing until is has cooled.

4. Never overfire this stove by building excessively hot fires.

5. If stove begins to glow or turn red, you are overfiring the stove.

6. Inspect stovepipe every 60 days. Replace immediately if stove pipe is rusting or leaking

smoke.

7. Inspect the stove pipes, connectors, and chimney twice monthly during the heating season

and clean if necessary.

CAUTION: SLOW BURNING FIRES AND EXTENDED USE MAY CAUSE EXCES-

SIVE CREOSOTE BUILDUP. IGNITION OF CREOSOTE/SOOT OR OVERFIRING

MAY CAUSE CHIMNEY FIRE. CHIMNEY FIRES BURN EXTREMELY HOT AND

MAY IGNITE SURROUNDING MATERIALS. IN CASE OF CHIMNEY FIRE CALL

THE FIRE DEPARTMENT IMMEDIATELY.

CHIMNEY MAINTENANCE - Creosote/Soot Formation and Need for Removal

When wood is burned slowly, it produces tar and other organic vapors which combine with ex-

pelled moisture to form creosote. The creosote vapors condense in relatively cool chimney flue

of a slow burning fire. As a result, creosote residue accumulates on the flue lining. When ignit-

ed, this soot/creosote makes an extremely hot fire.

The chimney and the chimney connector should be inspected at least twice monthly.

If creosote/soot has accumulated, it should be removed. Failure to remove creosote/soot may

cause a house or building fire. Creosote/soot may be removed by using chimney brush.

Chimney fires burn very hot. If the chimney connector glows red, immediately call the fire de-

partment.

PROVIDE AIR INTO THE ROOM FOR PROPER COMBUSTION.

CAUTION: HOT WHILE IN OPERATION. KEEP CHILDREN, ANIMALS, CLOTH-

ING AND FURNITURE AWAY FROM THE STOVE. DO NOT TOUCH HOT STOVE.

CONTACT MAY CAUSE SKIN BURNS. TRAIN CHILDREN TO STAY A SAFE DIS-

TANCE FROM THE UNIT. CHILDREN SHOULD BE ALL THE TIME CAREFULLY

SUPERVISED WHEN THEY ARE IN THE SAME ROOM WITH THE STOVE.

CAUTION: NEVER USE CHEMICALS, GASOLINE, KEROSENE, CHARCOAL

LIGHTER FLUID OR SIMILAR FLAMMABLE LIQUIDS TO START OR FRESHEN

UP A FIRE IN THE STOVE.

KEEP ALL FLAMMEBLE LIQUIDS AWAY FROM THE STOVE-WHETER IN USE

OR IN STORAGE.

OPERATING SAFETY PRECAUTIONS

1. NEVER BUILD EXTREMELY LARGE FIRES IN THE STOVE AS DAMAGE TO

THE STOVE OR SMOKE LEAKAGE MAY RESULT.

2. NEVER OVERFIRE THIS STOVE BY BUILDING EXCESSIVELY HOT FIRES AS

A HOUSE OR BULDING FIRE MAY RESULT. YOU ARE OVERFIRING THE

STOVE IF STOVE OR STOVE PIPE BEGINS TO GLOW OR TURN RED.

3. PROVIDE AIR INTO THE ROOM FOR PROPER COMBUSTION.

4. USE SOLID NATURAL AIR DRIED (SEASONED) WOOD and COAL, only.

5. INSPECT STOVE PIPES, CHIMNEY AND STOVE AT LEAST TWICE A MONTH

AND CLEAN IF NECESSARY.

6. WHILE IN OPERATION, KEEP THE FEED DOOR CLOSED ALL THE TIME,

EXCEPT WHILE TENDING THE FIRE. ALWAYS OPEN DRAFT CONTROLER

BEFORE OPENING THE FEED DOOR.

ABOUT DRAFT:

The principle of draft is that warm air rises. Your chimney provides draft which sucks the

smoke up the chimney. The stove does NOT PUSH out the smoke. Your stove has been design

and approved for use under normal conditions. Unacceptable smoking usually indicates poor

draft in your chimney. Normal operating draft for this stove is 12 Pa +- 2 Pa( 0.04 w.c. - 0.055

w.c.). For draft above 15 Pa ( 0.06 w.c.) install a stovepipe damper. Gauges to measure draft are

readily available at stove stores and are economical to rent or purchase.

Should you have a problem with inadequate draft, you should contact a licensed heating and

cooling contractor for assistance in solving the problem.

PROBABLE CAUSES FOR SMOKING ARE:

Insufficient chimney height above nearby obstructions.

Clogged or obstructed chimney system

Downdraft caused by nearby trees, hills, buildings, etc.

Negative draft. In a cold chimney, a cold air column rushing down the chimney can prevent

stove start-up causing the stove or chimney pipe joins to smoke. SOLUTION: Open nearby

window, and use small strips of newspaper or tinder loosely placed in the firebox that will pro-

vide quick and hot heat up the chimney, thereby reversing draft.

SINGLE WALL PIPE-MINIMUM CLEARANCES FOR USA/CANADA

Some example of clearance reduction;



Using heat shields on back and sidewalls allowing at least 1" of space away from the

walls for ventilation. The inch spacing is necessary to ensure air circulation between

the protection and the wall so that the wall is not subject to high temperatures. The

spacer used must be non-combustible. Another method to achieve the same type of

protection is using brick or masonry with 1" air space between the brick or masonry

and the wall. When reducing distances, please check local codes and consult with

professional installer. Reduced installation must comply with NFPA 211 or CAN/

CSA-B365

- WARNING: Do not place stove to close to the shield. There should be enough space

between for proper air ventilation.

1. INTRODUCTION

Read the instructions carefully and follow the rules and recommendations. Hereinafter you will find

the data regarding the stove itself, as well as the recommendations for the installation and

maintenance of the stove.

The efficiency of a stove depends on its correct installation, which must be carried out by a

professional following the highest standards and the safety regulations in force.

The place you intend to install the stove must have sufficient airspace and the floor and surrounding

object must be made of a non-flammable material.

Pay attention to the bearing capacity of the floor. In case that the floor cannot endure the weight of

the stove, it is necessary to reinforce it or set additional girders respecting advices of experts.

Moreover, if there is a flammable floor, it must be protected by an insulating plate (steel, brass,

marble, stone, etc.), which extends at least 46 cm(18”) from the front and at least 20 cm(8”) from

the sides. (picture 1). Minimum size 37”(94cm)W x 44(112cm)”D

Do not place armchairs, seats, curtains or any other flammable objects unmentioned here within 100

cm(40”) from the stove, as well as within 70 cm(27.6”) on the sides, and 40 cm(15.8”) from the

back side. (picture 2)

picture 1 picture 2

The cast iron parts are protected by heat resistant paint and during the first few exploitations smoke

and smells which are products of paint stabilization occur. The room has to be properly ventilated.

The stove is to work with the doors closed.

Open the door only in the case of fuel addition. Open the door slowly in order to equalize the

pressure. Abrupt door opening can cause smoke suppression.

Add fuel only when ember is created.

The stove is heated during operation, so take the necessary measures of precaution. The door handle

is heated during operation so use a glove when opening the door. Do not touch hot parts of the

stove.

We recommend installing smoke pipes with installed smoke gasses regulator for obtaining optimal

results.

Children should not be allowed to play near the stove or handle it.

Provide continuous flow of combustion air.

It is forbidden to place explosive devices and matters into the hearth and on parts of the stove.

Parts of packing should be properly disposed. Elements from cardbox, wood or plastic which are

entered into the furnace space should be taken out before putting the stove into operation. Ne

careful when taking out the packaging because wooden bars are connected with rails.

IN CASE OF NON-OBSERVANCE OF THE INDICATIONS ABOVE-QUOTED, THE

MANUFACTURER DISCLAIMS ALL RESPONSIBILITIES FOR POSSIBLE DAMAGE.

3. WORKING PRINCIPLE OF THE STOVE

3.1 Description of the stove

The stove is designed to be used for indoor heating. The heat is diffused by radiation through the

panoramic glass and the parts of the stove made of cast iron.

Parts of the stove are made of cast iron, and the hearth is equipped with a panoramic door with heat

resistant glass.

The stove has the primary and secondary air control by which the combustion air is adjusted. The

primary air control must be completely opened during the lightning phase (15 – 20 minutes).

During wood combustion, the primary air control is closed, otherwise the wood burns fast. The

secondary air control enables the glass to stay clean during wood combustion and provides

additional combustion.

3.2 Installation

The installation of the stove must be carried out by qualified people who are aware of the

safety measures regarding the stove installation. A badly installed stove can cause serious accidents

(chimney fires, burning of insulating materials, etc).

3.3 Lighting the stove for the first time

The first time the stove is lit, there will be smoke and odor given off due to the drying of the

protective color. That is normal, because the color stabilizes on temperatures over 350°C.

THE ROOM MUST BE PROPERLY VENTILATED.

Before the lighting, all parts should be cleaned with a dry cloth to remove dust and impurities.

- Upon the first ignition of the stove, we suggest loading recommended quantity of fuel reduced to

half in order to test the stove.

3.4 Ventilation of the room

Good ventilation is essential in order to provide proper operation without any risk to people who

use the room where the stove is installed, because during the combustion the stove uses the oxygen

from the air. It is necessary that the room has adjustable air openings.

ATTENTION

In case of non-observance of the indications, the manufacturer disclaims all responsibilities.

Modifications on the stove are not allowed.

4 THE FLUE

Special attention must be paid to the quality of the flue which must be made in accordance with the

standards. The flue must be regularly maintained. The stove is connected to the flue through a

connection on the upper or back side of the stove, by the appropriate smoke pipes. The smoke pipe

must not be positioned too deep in the flue so as not to decrease the surface of the cross-section and,

in that manner, disturb the draft in the flue.

The draught in the flue

An inadequate draught is exclusively the main reason behind most complaints of poor stove

operation! Necessary draught for this type of stove is 12 Pa.

A lower value does not permit proper combustion with the consequent formation of carbon deposits

and excessive production of smoke, which, being unable to flow to the exterior will escape through

the grills or door.

If the draught value is too high, combustion will be too fast, with the consequent dispersion of the

heat through the flue. If the draught is greater than 15Pa, the elements for draught reduction should

be installed.

The signs of a bad draught are:

−

dirty glass, boiling handle

−

smoke coming out into the room

4.1 General characteristics

Add chimney sections, according to the manufacturer’s installation instructions. The chimney must extend at

least, 3 feet above its point of contact with the roof and at least 2 feet higher than any wall, roof, building or

obstacle within 10 feet horizontally.

The chimney guarantees the conveyance of the fumes outwards even when there are strong

horizontal winds and stops them from being blown back down the chimney.

Bad maintenance of chimney is the cause of flue obstruction, due to the breaking and detachment of

plaster, refractory bricks etc. of which the flue is made, as well as due to the combustion product

deposits and intrusion of foreign objects.

Chimney must have sufficient heat insulation, otherwise it can lead to condensation.

The internal parts of the whole flue should have a smooth surface, and the material used should be

refractory and resistant to their degree of acidity, and should be impermeable to gases.

4.2 Chimney recommendations

The internal part of the whole flue should have a smooth surface, and the material used should be

resistant to heat and impermeable to gases.

Minimum height, from the pipe

4.3 Connection of the stove to the flue

The metal tube connecting the stove to the flue must never have a smaller diameter than the

outlet hole of the appliance.

Try to avoid too many curves and horizontal sections; if this is impossible, ensure that there is

always a slope of at least 2/3 cm(0.78”/1.18”) per linear meter as compensation.

The same flue must never be used for more than one appliance.

Do not decrease the flue section by positioning the pipe connecting the stove and the flue too deep

in the flue.

4.4 Cleaning the tubes and flue

Every time you notice the draught is becoming difficult, you should clean the stove, the tubes,

and the flue.

The removal of soot and carbon residues must be carried out to the highest standards using

appropriate means. Cleaning should be performed when the stove is cold.

The junction pipe for the connection to the chimney must be shortest possible and the junction

points of the single pipes must be hermetic. The connection to the chimney must be performed with

stable and strong pipes. The pipe for smokes exhaust must be fixed hermetically to the chimney.

ATTENTION: Possible flammable pieces in the area of 20cm (8”) around the connection pipes

must be changed with fireproof and not sensitive to heat materials.

For a good operation of the equipment it is essential that in the installation place, there is sufficient

air for combustion. This means that through suitable openings, air must circulate for the

combustion, even with doors and windows closed.

The draught in the chimney should be 12 Pa – The measurement must be done always with the

stove being hot. When the draught exceeds 15 Pa it is necessary to reduce the same with the

installation of an additional flue adjuster (butterfly valve) on the exhaust pipe or in the chimney.

5. WOOD

Only burn dry wood! You must not only select quality wood but it must also be dry at the

moment in which you use it.

Remember that the calorific power of the wood drops considerably as the presence of

humidity means that a large part of the heat produced is used to evaporate the water and,

furthermore, the risks of obstruction increase rapidly with the condensation of the vapors in the flue.

Recommended humidity of wood is up to 20%.

5.1 DRYING

Damp wood not only burns badly but also makes the lighting of the fire difficult and damages

the flue. The water vapor transports condensible products such as acetic acid, alcohol, methyl

alcohol and tars which contribute to the formation of incrustations which are detrimental for the

efficiency of your stove.

Fresh cut wood is useless as a fuel. Actually a considerable part of the energy produced is only

used to evaporate the water, which is up to 75% in young wood without bark.

To obtain dry wood (15%-20% humidity) you must cut the weak wood (in winter) to the desired

length and cut it again in pieces with a maximum diameter of 8-15 cm (3.15”-5.9”). You must then

put them in a ventilated shelter for at least 2 years (4 for oak, the first with exposure to the rain to

eliminate the tannin).

You must stack the wood without compressing it to allow the passage of air, which, when

circulating between pieces of wood, releases the humidity and aids drying.

5.2 HOW TO SELECT THE RIGHT WOOD

To obtain combustion and optimum efficiency from your stove, you must use firewood on the

basis of the following list.

TYPE OF WOOD QUALITY

HORNBEAM EXCELLENT

OAK EXCELLENT

ASH VERY GOOD

MAPLE VERY GOOD

BIRCH GOOD

ELM GOOD

BEECH GOOD

WILLOW BARELY SUFFICIENT

FIR BARELY SUFFICIENT

ALDER-SCOTCH PINE POOR

LARCH POOR

IME VERY BAD

POPLAR VERY BAD

YOU SHOULD ABSOLUTELY NEVER USE:

Green or damp wood, treated wood (railway sleepers, plywood off-cuts, painted wood, etc.), low-

grade anthracite and coke.

THE USE OF THE ABOVE LISTED MATERIALS AND DAMAGES CAUSED BY THEM

ANNUL ANY FORM OF GUARANTEE AND THE MANUFACTURER DECLINES ALL

RESPONSIBILITY.

6. CLEANING THE STOVE

We recommend removing the ash produced every day. Never allow the ash to accumulate to the

point where it touches the grate; this would obstruct the circulation of primary air and slowly

suffocate the fire.

When cleaning the outside surfaces of the stove, avoid abrasive products which would damage the

protective paint. Do not use chemicals that contain diluent, because the cast parts are protected by

heat resistant paint.

Panoramic door glass should be cleaned with normal detergent and exclusively after getting cold.

After cleaning, rinse with pure water and dry. To clean the parts in tiles use non -abrasive

detergents, water and a soft cloth which do not damage the glaze.

7. CONSUMABLES

The following are considered consumables and therefore not covered by the warranty:

all gaskets, the parts in ceramic hardened glass, the facing of the hearth, the paints, the ceramics and

the parts with chemical coating (chrome, nickel, zinc parts). The warranty does not cover damages

caused by improper installation, incorrect connection not in compliance with the instructions which

accompany the product, or breakdowns caused by tempering from unqualified or unauthorized

personnel.

8. SUMMER PAUSE AND RECCOMENDATIONS FOR THE SEASON

After you have cleaned the hearth, the chimney and flue, trying to eliminate completely the ash

and other residuals, you must close the hearth door and its regulators; in case that you are

disconnecting the device from the flue, you must close its openings in order to enable operation of

other devices connected to the same flue.

The cleaning of the flue should be done at least once a year. Check the state of gaskets and

replace them if necessary.

If there is dampness in the room where the stove has been placed, we advise you to put

absorbent salts into the hearth. If you want to keep for long the aesthetic look of the stove it is

important to protect its internal walls in cast iron with neutral Vaseline.

9. SOLUTIONS OF THE PROBLEMS

9.1 The appliance does not work

−

Check that the entrance of the chimney has been carried out perfectly.

−

Check whether the dimensions of the chimney are correct and appropriate to the appliance.

−

Check whether the flue is well isolated from thermo agents and made according to the

standards.

−

The doors of the stove must be well sealed.

9.2 Difficulty in lighting the fire

−

Open the primary air and the smoke register.

−

Use very dry wood.

−

Air the room in order to have a great quantity of oxygen.

−

The flue must be appropriated to the appliance used.

9.3 Smoke comes out

−

Check if the primary air register is opened.

−

Check if the entrance of the chimney presents leaks.

−
