Technical data

Note: heater dimensions are specified in Appendix 1

GENERAL DATA

IMPORTANT! Carefully select the heater for the volume of the room. A heater with a small heating capacity will require a more intensive heating during a longer time, which will shorten its service life.

Kindly note that:
When selecting a heater, it is necessary to give consideration to the material of the walls and the ceiling of the room of installation. If they are not heat-insulated (concrete, brick, glass, etc.), a heater of greater power is required, and additional 1.2 m3 of volume should be added per each square meter of surfaces made of such materials. If the walls are made of massive logs, the design cubing shall be increased by a factor of 1.5.

Example 1:
A sauna room volume equals 10 m3 The sauna has a 3-m wide and 2-m high brick wall.
Calculations: 10+2х3х1.2 = 17.2. Consequently, this room is equivalent for a sauna room with a volume of approximately 17 m3

Example 2:
A sauna room volume equals 10 m3 The sauna has a 0.8-m wide and 2-m high glass door.
Calculations: 10+2х0.8х1.2 = 11.9. Consequently, this room is equivalent for a sauna room with a volume of approximately 12 m3

Example 3:
A sauna room volume equals 10 m3 The sauna walls are made of massive logs.
Calculations: 10х1.5=15. Consequently, this room is equivalent for a sauna room with a volume of approximately 15 m3 .

OPERATION MANUAL

Read this manual carefully before commencing installation and operating the heater. Keep it for future use

Safety measures

IMPORTANT! Consult your doctor about your health-related limitations. Bear in mind that prolonged exposure to hot sauna environment can be harmful. Avoid being in a heated sauna and steam bathing under the influence of alcohol, drugs, medications, etc. Do not sleep in the heated sauna. Take care while moving around in the sauna as benches and floor can be wet and slippery.

IMPORTANT! Consult your pediatrician whether visiting sauna and steam bathing is allowed to your children. Do not let your children approach the heater. Do not leave children as well as handicapped people and people with fragile health unattended in the sauna.

IMPORTANT! Be careful with hot parts of the heater and stones, and also avoid putting steam on, if you or someone else is near the stone heater, as it can cause burns.

IMPORTANT! Do not use the steam room or the heater surface to dry clothes or other objects to prevent fire.

Note: metal surfaces of the heater can corrode in coastal and humid climate.

Heater design and operation

Note: overall view and location of the heater main elements are shown in Appendix 2. Internal design and operation of the heater is shown in Appendix 3.
Firebox as well as other critical elements of the heater is made of rolled steel of the required thickness that can withstand any design loads.

The effective design for heating up the stones and the steam room is due to two postcombustion ducts, as well as a heating flue with a double top protection allowing to direct hot air from the firebox into the closed stone heater and stoking in the heating flue itself. Also, air convection between the heater firebox, radiators, and protective shield plays a significant role. Heater models of “Long” version are equipped with extended heating flue that allows the heater to be fired from the adjacent room. Some of the Grill’D heater models of Long version are equipped with a telescopic heating flue, which allows adjusting the length of the flue depending on the wall thickness.

Note: dimensions of heaters with a telescopic heating flue are shown in Table 1 and Appendix 1 as a range of values.

All heater models can be optionally equipped with special reinforcing devices (refer to Appendix 4) made of heat resistant high-alloyed corrosion-resistant steel that enhance combustion and additionally protect the heater firebox from destruction due to exposure to high temperature. The devices have ducts for supplying additional combustion air, and when it enters the firebox, the air passes partially above the fire into its upper part, where post-combustion of flue gases occurs. Additional heat is generated during this process, thus enhancing the heater’s efficiency.

There is a grate at the bottom of the heater (refer to Appendix 4). Ash falls through the sheets of the grate into the ash drawer, which allows convenient cleaning of the heater without interruption of burning. The grate is one of the most thermally loaded parts of the heater, it is fabricated of high duty rolled steel with a thickness of 5 mm.

The heater firebox door is fabricated of steel and thermal glass. The door opening angle is sufficient for convenient loading of fuel and allows visual monitoring of the burning process due to the availability of the glass.

The outer surface of the heater is covered with anti-corrosion heat-resistant enamel.

IMPORTANT! Unauthorized modification of the heater is prohibited. The Manufacturer reserves the right to make modifications to the design of the heater that do not impair its consumer properties.

Zorro series

A special feature of the Zorro heater is the possibility of installing a closed stone heater. In basic configuration it is a heater with a stone mesh. With the closed stone heater, the heater allows obtaining several steam modes:
Fine steam mode is a mode for special ultralight steam obtained by feeding water through the funnels to the inner compartment of the stone heater, the stones in which are heated to temperatures above 400 °С. Given the plug is installed contiguously and the pressure is growing, the steam escapes through a nozzle located on the lid imitating the singing of blizzard.
Traditional steam mode is achieved, when water is poured onto the outer stone heater.

Heater commissioning

It is recommended to carry out a preparatory stoking of the heater prior to operation. Compound for metal protection and volatile components of the heat- resistant enamel evaporate as a result of heating up.

IMPORTANT! Stoking to be carried out outdoors, away from combustible surfaces and materials, in compliance with fire safety measures and safe work practices.

1. Remove all packing elements, stickers, magnets, if available.
2. Install a portion of chimney stacks vertically (about 2 meters).
3. Put 3-4 logs on the grate in such a way as to ensure free access of air to the combustion area, namely: lay the firewood loosely, adjust the ash drawer gap to be within 50 mm
4. Ignite the firewood loaded into the firebox. The preferred ignition method is using birch bark, wood chips and other natural materials, or using paper or throwaway newspapers.
5. Close the door.
6. Partly close the ash drawer after heating up of the chimney and development of stable draft (usually after burning of the first load of firewood in approximately 30-45 minutes), leaving a gap within 10 mm. It is necessary to constantly ensure sufficient draft, while avoiding the development of excessive one (it can manifest itself as humming of the heater, too erratic flame) that leads to heating of the firebox red hot, which significantly reduces the heater service life. Control the draft by adjusting the ash drawer gap.
7. Add firewood into the firebox as it is consumed. Carry out stoking until smoke and odor disappear (for one hour approximately), then let the heater cool down without removing the coals.

IMPORTANT! During the first heating up avoid the chance of mechanical impact and occurrence of water on the paint coating of the heater (do not put the stones into the stone heater, do not rub the surface, do not pour water).

IMPORTANT! Do not heat up the heater at constant excessive draft which can lead to heating of the firebox red hot, as this will reduce its service life. Control the draft by adjusting the ash drawer gap.

IMPORTANT! Install the heater on the place of permanent operation only after complete cooldown.

IMPORTANT! In case a water tank is installed, it shall be cleaned thoroughly before use. The water tank shall be filled before heating

Combustion material

Approved fuel types: dry wood, fuel briquettes without artificial binder resins with a maximum burning point less than 820 °C.

Recommended fuel types: hardwood with a moisture content not more than 20 % with a maximum burning point less than 820 °C.

The moisture contained in the firewood has a significant impact on the combustion process and the heater efficiency, hence to reduce the rate of soot formation on the walls of the chimney and the flues of the firebox, it is necessary to use the recommended fuel types.

IMPORTANT! Different fuel types have different heat of combustion. When a large amount of firewood with a high heat of combustion is burned, as well as when the heater is operated at a constant excessive draft, the heater service life decreases.

IMPORTANT! The following is not recommended as fuel:

• coniferous, resinous tree species (spruce, fir, pine, etc.);
• construction and other materials containing chemicals, glue, etc. ;
• vegetation residues (grass, leaves, etc.).

IMPORTANT! The following is prohibited to be used as fuel:

• combustible materials with a high heat of combustion (coal, wood chipboard, plastic, pellets, and so on);
• painted or impregnated wood;
• waste (plastic, rubber, textiles, leather, etc.).

Stones for stone heater

The permissible stone sizes are given in Table 1.
Only the stones intended for sauna shall be used as heater stones.

IMPORTANT! Put the stones into the heater only after its complete cooldown.

• Clean the stones from dirt and dust before putting into the heater, thoroughly rinse them with water.
• Put large stones down and small ones up.
• Choose the option which suits you the best when putting the stones into the outer stone heater, namely:
  • put your stones loosely in order to allow for free circulation and intense convection of air, thus ensuring maximum heating of the steam room;
  • closely laid stones prevent convection and provide maximum protection from infrared radiation.
• Fill in the inner compartment of the stone heater with stones up to no more than 70% of the volume.
• Do not obstruct or shut off the nozzle located on the lid of the inner compartment of the stone heater, while laying stones into outer or inner compartments of the stone heater.

IMPORTANT! It is prohibited to use halite to fill stone heaters.

Heater operation

IMPORTANT! Before each heating up of the heater, make sure that there are no foreign objects in the firebox, ash drawer or in the chimney, and that there is chimney draft.

Note: Burning of firewood inside the heating flue is allowed.

1. Remove all unnecessary and foreign objects from the firebox and chimney, remove ash from the ash box.
2. Put 3-4 logs on the grate in such a way as to ensure free access of air to the combustion area, namely: lay the firewood loosely, adjust the ash drawer gap to be within 50 mm. In heater models of Short version firewood can be loaded vertically.
3. Ignite the firewood loaded into the firebox. The preferred ignition method is using birch bark, wood chips and other natural materials, or using paper or throwaway newspapers.
4. Close the door.
5. Partly close the ash drawer after heating up of the chimney and development of stable draft (usually after burning of the first load of firewood, approximately in 30-45 minutes), leaving a gap within 10 mm. It is necessary to constantly ensure sufficient draft, while avoiding the development of excessive one (it can manifest itself as humming of the heater, too erratic flame), that leads to heating of the firebox red hot, which significantly reduces the heater service life. Control the draft by adjusting the ash drawer gap.
6. Close the ash drawer completely after the air in the bath house heats up to a temperature of 60-70оС.
7. As a rule, 1-2 logs are enough to maintain the temperature in the steam room. In case the temperature decreases, open the ash drawer and adjust the gap within 3-10 mm in order to kindle the firewood (it takes more time, when the ash drawer is closed), and close the ash drawer afterwards. If the temperature keeps decreasing, then adjust the ash drawer gap within 3-10 mm and keep it until the temperature reaches 60-70оС, then close the ash drawer. Bear in mind, that excessive heating (for example, several full loads in a row) leads to overheating and shortens the heater and chimney service life, and can also cause a fire.
8. When additional firewood is required, open the door smoothly, without jerks. Load the firewood and close the door. Adjust the draft.
9. After the completion of bathing procedures prepare the room and the heater for closing: they are to be aired and dried. To do so

• Put 4-5 logs into the heater firebox, kindle them. Set the ash drawer gap to be approximately 10 mm. Open the hatches/windows, that serve for airing, and the door in order to develop a small draft.
  Note: the air and the bath house to remain heated, the air to move barely noticeably, i.e. it shall be quite warm or even hot in the bath house (up to 60-70оС).

• Heat up the bath house in this mode, the firewood will burn in approximately 30-45 minutes. Completely close the ash drawer after formation of active red coals. Close the hatches/windows and the door, leave the bath house until next use.

• The room and the heater to be periodically checked after such stokings: there shall be no water or moisture in the stone heater, the stones shall be dry, and so shall be the boards in the rooms. If the rooms and the heater did not dry thoroughly, it is allowed to carry out additional stoking of the heater with a completely closed ash drawer.

IMPORTANT! The following is prohibited:

• using explosive, toxic, highly flammable substances, paints, solvents, gasoline, etc., to ignite the firewood;
• operating the heater at a constant excessive draft in the firebox.

IMPORTANT!

• Partial burning out of heat-resistant enamel is possible on the most thermally loaded elements of the heater during operation, which is not a manufacturing defect.
• The firebox metal may become slightly deformed during operation, which is not a manufacturing defect provided the integrity of weld joints is preserved.
• In case there is a hot water tank, water shall be drained from the tank every time after termination of the heater operation, if the room temperature drops below + 5 °С during interruptions of the heater operation.

Water in the sauna

The water poured onto the stones shall be clean tap water. Ensure the water quality. Water with a high content of iron, salt, humus, or lime can lead to early corrosion of the heater elements. For example, seawater will lead to rapid corrosion of the stone heater. The tap water quality shall meet the following requirements:

• humus content <12 mg/liter;
• iron content <0.2 mg/liter;
• calcium content <100 mg/liter;
• manganese content <0.05 mg/liter.

IMPORTANT! Water shall only be poured onto the stones. If water is poured on heated steel surfaces, they can be deformed due to high differential temperature.

IMPORTANT! It is prohibited to use solution of salt to generate steam during operation: pouring it into the closed stone heater (if available), pouring it onto outer stone heater and the heater metal.

Maintenance

Routine maintenance of the chimney, heater and its parts is the key to their efficient and safe operation, your safety and safety of your close ones!

IMPORTANT! Carry out maintenance works on the heater and chimney only after their complete cooldown.

IMPORTANT! Take measures recommended for safety. Use personal protective equipment required for such works.

The heater and chimney shall be cleaned of soot before the commencement of the heating season, as well as during the entire heating season at least once every three months. Cleaning to be performed mechanically. Use special devices, tools and machines (brush, cleaner, scraper, sinker, vacuum cleaner, etc.). The selection of the necessary tools is made based on the needs of the cleaning works. Cleaning the flue channels of the heater is carried out through the cleanout hole after removing the cap (refer to Appendix 2): unscrew nuts, remove the cap and baffle plates. After cleaning the flue channels, install the cap and baffle plates, makeup and tighten the nuts.
Soot in the chimney accumulated due to poor cleaning, as well as incomplete combustion of fuel, can break into flames.

Procedure in case of fire in the chimney:

1. Close the door, the ash drawer, and the flue damper (if available).
2. Call the local fire department.
3. Do not attempt to extinguish the fire with water.
4. After an ignition of soot, a specialist shall check the heater and the chimney for the possibility of further operation.

IMPORTANT! The use of cleaning log (briquettes), homemade compounds creating high temperature in the heater firebox and chimney, is prohibited for the purposes of burning the soot deposited in them.

The stones deteriorate with time as the heater is operated, this is why it is necessary to turn them over and reposition in the stone heater at least once a year, when the heater is frequently operated. Remove the destroyed stones and their parts from the stone heater, replace them with new ones. Before laying the stones, clean the heater with a wet cloth.
The ash drawer shall be cleaned at all times before heating, so that the combustion air passing through the ash drawer to cool the grate, thereby increasing its service life. If there is a thermal glass door, use soft cleaning waste with special agents for cleaning heatresistant glass of fireplaces and heaters in accordance with the application instructions. Please, obey fire safety rules!
