Safety

Please note: All safety regulations must be complied with strictly.
Please read carefully the instructions supplied with the appliance for installation, use and maintenance before using the appliance.
The appliance must be installed in accordance with the legislation and requirements applicable in your country.
All local regulations and the regulations relating to national and European standards must be observed when installing the appliance.
The appliance should preferably be installed by an authorised installer. Installers will be aware of the applicable regulations and requirements.
The appliance is designed for heating purposes. All surfaces, including the glass and connecting tube, can become very hot (over 100°C)! When operating, use a so-called ‘cold hand’ or an oven glove.
Ensure that the appliance is adequately guarded if young children, disabled people, the elderly or animals are present in the  vicinity.
Safety distances from flammable materials must be strictly adhered to.
Do not place any curtains, clothes, laundry or other combustible materials on or near the appliance.
When in use, do not use flammable or explosive substances in the vicinity of the appliance.
Avoid chimney fires by having the chimney swept regularly. Never burn wood with the door open.
In the event of a chimney fire: close all the appliance’s air inlets and alert the fire service.
If the glass in the appliance is broken or cracked, it must be replaced before the stove is used again.
Do not exert force on the door, do not allow children to pull on the opened door, never stand or sit on the opened door and do not place heavy objects on the door.
Ensure that there is adequate ventilation in the room in which the appliance is installed. If ventilation is insufficient, combustion will be incomplete, which may lead toxic gases to spread through the room. See the chapter ‘Installation requirements’ for more information on ventilation.

Installation requirements

General

• The appliance must be connected tightly to a wellfunctioning flue.
• For connection measurements: see ‘Technical data’ appendix.
• Ask the fire service and/or your insurance company about any specific requirements and regulations.

Flue
The flue is needed for:

• Removal of combustion gases via natural draught.
  **** As the warm air in the flue or chimney is lighter than the outside air, it rises.

• Air intake, needed for the combustion of fuel in the appliance.

A poorly functioning flue or chimney can cause smoke to escape into the room when the door is opened. Damage caused by smoke emissions into the room is not covered by the warranty.
Do not connect multiple appliances (such as a boiler for central heating) to the same flue, unless local or national regulations allow this. In the event of two connections ensure that the difference in height between the connections is no less than 200 mm.
Ask your installer for advice regarding the flue. Refer to the European norm EN13384 for a correct calculation for the flue.
The flue must satisfy the following requirements:

• The flue or chimney must be made of fire-resistant material, preferably ceramics or stainless steel.

• The flue or chimney must be airtight and well cleaned and guarantee sufficient draught.
  **** A draught/vacuum of 15 – 20 Pa during normal operation is ideal.

• Starting from the flue spigot, the flue must run as vertically as possible. Changes in direction and horizontal pieces disrupt the outward flow of combustion gases and may cause soot deposits.

• To prevent combustion gases from cooling down too much, which reduces the draught, ensure that the interior diameter is not too big.

• The flue or chimney should ideally have the same diameter as the connection collar.
  **** For nominal diameter: see ‘Technical data’ appendix. If the smoke channel is well insulated, the diameter may be slightly bigger (up to 2x the section of the connection collar).

• The section (area ) of the smoke channel must be constant. Wider segments and (in particular) narrower segments disrupt the outward flow of combustion gases.

• In fitting a cover plate/exhaust cap to the flue: make sure that the cover does not restrict the flue outlet and that the cap does not impede the outward flow of combustion gases.

• The flue must end in a zone that is not affected by surrounding buildings, trees or other obstacles.

• The flue outside the house must be insulated.

• The flue should be at least 4 metres high.

• As a rule of thumb: 60 cm above the ridge of the roof.

• If the ridge of the roof is more than 3 metres from the flue: use the measurements given in the following figure. A = the highest point of the roof within a distance of 3 metres.

Room ventilation
For good combustion, the appliance needs air (oxygen). This air is supplied via adjustable air inlets from the area in which the appliance is installed.
If ventilation is insufficient, combustion will be incomplete, which may lead toxic gases to spread through the room.
As a rule of thumb, the air supply should be 5.5 cm²/kW. Extra ventilation is needed when:

• The appliance is in a well-insulated area.
• There is mechanical ventilation, for example a central extraction system or an extraction hood in an open kitchen.

You can provide extra ventilation by having a ventilation louvre fitted on the outside wall.
Make sure that other air consuming appliances (such as tumble-driers, other heating appliances or a bathroom fan) have their own supply of outside air, or are switched off when you use the appliance.
This appliance also has a connection to outside air.
We recommend that you use it where this is possible (see ‘Product description’ below).
Floor and walls
The floor on which the appliance is placed must have sufficient bearing capacity. The weight of the appliance is given in the appendix “Technical Data appendix”.
Protect flammable flooring from heat radiation by means of a fireproof protective plate. See the appendix “Distance from combustible material”.
Remove combustible material such as linoleum, carpets/rugs and similar materials below the fireproof protective plate.
Keep sufficient distance between the appliance and combustible materials such as wooden walls and furniture.
The connecting tube also radiates heat. Ensure that there is sufficient distance or a shield between the connecting tube and combustible material.
The rule of thumb for a single-walled tube is a distance of 3x the diameter. If a lining shell is fitted around the tube, a distance of 1x the diameter is permissible.
Carpets and rugs must be at least 80 cm away from the fire.
Use a fireproof floor plate to protect a flammable floor from any ash that may fall in front of the stove. The floor plate must comply with national standards.
For the dimensions of the fireproof protective plate: see the appendix “Distance from combustible material”.
For further requirements with respect to fire safety, see the appendix “Distance from combustible material”.

Features of the appliance

• The appliance comes with a handle holder (see ‘Holder Cold Hand’) for the removable handle. The customer can attach this holder under the right-hand front leg, using the hexagonal nut supplied. This means the leg does not need to be unscrewed for attaching the holder.
• The appliance can be connected to the chimney at the rear or at the top.
• The base plate is grooved. The ashes that accumulate in the grooves act as an insulating layer to protect the base plate.

Installation

Preparation

• Please check the appliance for damage caused during transport or any damage or defects immediately after delivery.
  If you detect transport damage or any other damage or defects, do not use the appliance and notify the supplier.

Preparing the connection to the flue
When connecting the appliance to the chimney you have the choice of connecting via either the side, the rear or the upper side.
Installing and connecting

1. Position the appliance in the correct place, and make sure it is level.
2. Connect the appliance to the flue hermetically.

Never use the appliance without the cast-iron inner plates.
The appliance is now ready for use.

Use

First use
When you use the appliance for the first time, make an intense fire and keep it going for a good few hours. This will cure the heat-resistant paint finish. This may result in some smoke and odours. You could open windows and doors for a while in the area in which the appliance is located.
Fuel
This appliance is only suitable for burning natural wood, namely sawn and chopped wood that is sufficiently dry.
Do not use other fuels, as they can cause serious damage to the appliance.
The following fuels may not be used as they pollute the environment, and because they heavily pollute the appliance and flue, which may lead to a chimney fire:

• Treated wood, such as scrap wood, painted wood, impregnated wood, preserved wood, plywood and chipboard.
• Plastics, scrap paper and domestic waste.

Wood

• Hardwood, such as oak, beech, birch and fruit tree wood is the ideal fuel for your stove. This type of wood burns slowly with calm flames. Softwood contains more resins, burns faster and sparks more.
• Use seasoned wood that contains no more than 20% moisture. The wood should have been seasoned for at least 2 years.
• Saw the wood to size and split it while it is still fresh. Fresh wood is easier to split, and split wood dries more easily. Store the wood under a roof where the wind has free access.
• Do not use damp wood. Damp logs do not produce heat as all the energy is used in the evaporation of moisture. This will result in a lot of smoke and soot deposits on the appliance door and in the flue. The water vapour will condense in the appliance and can leak away through chinks in the stove, causing black stains on the floor. It may also condense in the chimney and form creosote. Creosote is a highly flammable compound and may cause a chimney fire.

Lighting
You can check whether the flue has sufficient draught by lighting a ball of paper above the baffleplate. A cold flue often has insufficient draught and consequently, some smoke may escape into the room instead of up the chimney. You can avoid this problem by lighting the fire as described below.

1. Stack two layers of medium-sized logs next to each other on the fire compartment.
2. Stack two to three layers of kindling crosswise on top of the logs.
3. Place a firelighter between the bottom layer of kindling and light the firelighter according to theinstructions on the packaging.
4. Close the appliance door and open the air slider (see 2 in the figure below) in the door completely (see 1 in the figure below; open is as far to the left as possible).
5.  Allow the fire to develop into a good blaze until there is a glowing bed of charcoal. You can then add fuel and adjust the appliance; see the chapter ‘Stoking with wood’.

Burning wood
After you have followed the instructions for lighting:

1. Slowly open the door of the appliance.

2. Spread the charcoal evenly across the bottom of the stove base.

3. Stack a few logs on the charcoal.
   Open stacking If the logs are stacked openly, the wood will burn quickly as the oxygen can reach each log easily. If you want to use the stove for a short while, make an open stack.
   Compact stacking If the logs are stacked tightly, the wood will burn more slowly as the oxygen can only reach some logs easily. If you want to burn wood for a longer period, make a compact stack.

4. Close the door of the appliance.

5. Control the fire with the air slider in the door.
   Fill the appliance half-way at most.

Advice
Never burn wood with an open door.
Regularly burn wood with intense roaring fires.
If you burn at a low setting frequently, tar and creosote may be deposited in the flue. Tar and creosote are highly combustible substances.
Thicker layers of these substances may catch fire if the temperature in the flue increases suddenly. By allowing the fire to burn very intensely regularly, layers of tar and creosote will disappear.
Low-intensity fires can also cause tar deposits on the stove window and door.
When the outside temperature is mild, it is better to burn wood intensely for a few hours instead of having a low-intensity fire for a long period of time.

• Control the air supply using the air vent in the door.
  **** The air supply via the air slider not only supplies air to the fire but to the glass as well, so that it does not get dirty so quickly.

• Always open the door carefully.

• Close the door immediately after adding fuel.

• Topping up with a few logs regularly is better than adding many logs in one go.

Extinguishing the fire
Do not add fuel and just let the fire go out. If a fire is damped down by reducing the air supply, harmful substances will be released. For this reason, the fire should be allowed to go out naturally. Keep an eye on the fire until it has gone out. All air inlets can be closed once the fire has died completely.
Removing ash
After wood has been burnt, a relatively small amount of ash remains. This ash bed is a good insulating layer for the stove base plate and improves combustion.
It is a good idea to leave a thin layer of ash on the stove base plate (not higher than the bottom of the bottom-most pane of the SAGA 107 model).
Remove any excess ash frequently (about once every three times of use).
You can remove the excess ash with the aid of a small shovel or ash vacuum cleaner.
Fog and mist
Fog and mist hinder the flow of flue gases through the flue. Smoke can blow back and cause a stench. If it is not strictly necessary, it is better not to use the stove in foggy and misty weather.
Resolving problems
Refer to the appendix ‘Diagnostic diagram’ to resolve any problems in using the appliance.

Maintenance

Follow the maintenance instructions in this chapter to keep the appliance in good condition.
Flue
In many countries, you are required by law to have your chimney checked and maintained.

• At the start of the heating season: have the chimney swept by a recognised chimney sweep.
• During the heating season and after the chimney has not been used for a long time: have the chimney checked for soot.

Cleaning and other regularly maintenance
Do not clean the appliance when it is still warm.

• Clean the exterior of the appliance with a dry lintfree cloth.

You can clean the appliance interior thoroughly at the end of the heating season:

• If necessary, first remove the cast-iron inner plates. See the chapter ‘Installation’ for instructions on removing and installing the inner plates.
• If necessary, clean the air supply ducts.

Inspecting cast-iron inner plates
The cast-iron inner plates are consumables and subject to wear-and-tear. Check the fire-resistant inner plates frequently and replace them when necessary.

• See the chapter ‘Placing vermiculite stones into the appliance’ for instructions on removing and installing inner plates.
  Never use the appliance without the cast-iron inner plates.

Cleaning front glass
Side glass panes (only model SAGA 107)
With the SAGA 107 model it is normal for the side glass panes to turn black a little bit. These side glass panes do not require cleaning. A moderate air flow passing the side glass panes ensures that a cosy glow remains visible and that the side glass panes do not turn black completely.
Front glass
Dirt clings less easily to well-cleaned glass (front glass in the door). Proceed as follows:

1. Remove dust and loose soot with a dry cloth.
2. Clean the glass with stove glass cleaner:
   a. Apply stove glass cleaner to a kitchen sponge, rub down the entire glass surface and give the cleaning agent time to react.
   b. Remove the dirt with a moist cloth or kitchen tissue.
   3. Clean the glass again with a normal glass cleaning product.
   4. Rub the glass clean with a dry cloth or kitchen tissue.

• Do not use abrasive or aggressive products to clean the glass.
• Wear household gloves to protect your hands.
  If the glass in the appliance is broken or cracked, it must be replaced before the stove is used again.
  Ensure that no stove glass cleaner runs between the glass and the cast-iron door.

Stove maintenance
Lubrication
Although cast-iron is slightly self-lubricating, you will still need to lubricate moving parts frequently.

• Lubricate the moving parts (such as guide systems, hinge pins, latches and air slides) with heatresistant grease that is available in the specialist trade.

Touching up damaged paint
Small areas of damaged paint finish can be touched up with a spray can of special heat-resistant paint, available from your supplier.
Ensure that the stove is not overburdened. If it does become overburdened then the surface gets very hot, possibly resulting in lasting damage to the enamel.
Checking the seal

• Check whether the door sealing rope is still in good condition and works well. The sealing rope is subject to wear and will need to be replaced over time.
• Check the appliance for air leaks. Close any chinks with stove sealant.
  Allow the sealant to harden fully before lighting the appliance, as any moisture in the sealant will form bubbles, resulting in a new air leak.

Placing vermiculite stones into the appliance

The stones can be replaced if they are broken.
The steps for replacement are provided below.
If you replace a complete set of vermiculite stones, begin with the back wall (see drawing 09-20023005).
The stone has no. 03.77695.000. This number is on the back and is no longer visible once the stone has been installed in the appliance.Next, place the two sides (see drawing 09-20023006). The sides have numbers 03.77698.000 and 03.77696.00 for the SAGA 101, and numbers 03.77699.000 and 03.77697.000 for the SAGA 107. These numbers are on the back and are no longer visible once the sides have been installed in the appliance.Next, place the baffle plate onto the back wall and the sides (see drawing 09-20023-007).
Number 03.77694.000 is visible on the top, so from beneath in the combustion chamber, this number is not visible.A cross section of the appliance with the back wall, a side, and the baffle plate in vermiculite is visible in drawing 09-20023-008.
Removing the vermiculite takes place in reverse order. First remove the baffle plate, then the sides. Finally, remove the back wall.The steps are shown on the photos on the next few pages.
Placing vermiculite stones with the help of photos
The numbers are on the back and are no longer visible once the vermiculite has been placed.

1. Placing vermiculite back wall

2. Placing vermiculite sides.
   • Sides with three holes for SAGA 107
   • Closed sides for SAGA 101

3. Placing the vermiculite baffle plate onto the sides.

The number is on the top and is therefore not visible in the combustion chamber.

Using the cold hand

You can opt for attaching the handle to the stove permanently or to use it as a removable handle.
A. Permanent fit (is delivered in this way):
Caution, do not get burned! The handle (indicated by no. 1 in figure 09-20023-009) gets hot. Use the glove supplied when you open and close the stove. We recommend the use of a cold hand (see below).
B. Option removable handle (cold hand).
You can unscrew the handle (see screw 2 in figure 09-20023-009). Next, you can detach the handle after opening or closing the door.![DOVER SAGA107 Wood Stove

• Figure 14](https://manuals.plus/wp-content/uploads/2022/11/DOVER-SAGA107 -Wood-Stove-Figure-14.jpg)The stove comes with a handle holder. You can attach it under one of the front legs with the help of the supplied hexagonal nut.
  Do not forget to close the hole in the door, which results when you remove the handle. Close the gap with the anti-leak screw supplied (see screw 1 in figure 09-20023-010). If you do not close the gap, hazardous smoke escapes from the appliance, and the appliance will not function properly.
