APPLICATION

• Grill’D brand wood-fired heater is designed to heat a steam room and adjacent premises of a bath house, as well as to generate steam and heat water. The heater allows obtaining various combinations of temperature and air humidity.
• IMPORTANT! When exploiting the heater commercially, daily, round-the-clock or in another heavy duty operating mode, the work load increases in 5-10 times. In case of such operating mode, the Manufacturer disclaims any warranty obligations.
• IMPORTANT! Carefully select the heater for the volume of the steam room. A heater with a small heating capacity will require a more intensive heating during a longer time, which will shorten its service life.

TECHNICAL DATA

Technical data is specified in Table 1. Heater dimensions are specified in Figures 1 and 2. Approved fuel types: hardwood with a moisture content not more than 25%, fuel briquettes without artificial binder resins.

HEATER DESIGN

• IMPORTANT! Overall views of the heaters and (or) of their elements may be slightly different from the ones shown in the figures.
• Heater firebox (6) is fabricated of high duty rolled steel. Use of such steel increases the heater’s durability and service life taking into account the firebox wall thickness of 3 mm, while the most critical elements are made of 5 mm thick steel.
• The effective design for heating up the stones and the steam room is due to the arrangement of heat exchange process not only via the surface of the stone heater bottom and the connection pipe (2), but also by means of air convection between the heater firebox and protective shield (1) through convection holes (Figure 4).
• Also, the protective shield screens high-level infrared radiation coming from the firebox walls as the heater is getting hot. Regardless its compact size, the stone heater has room for enough stones to obtain comfortable conditions in the steam room (see Table 1). Chimney connection pipe is a fixed element with a wall thickness of 5 mm. It serves as a mandatory transition element from the heater to the chimney. Heater models of Long version are equipped with a heating flue (3) allowing the heater to be stoked from the adjacent room.
• All heaters can be optionally equipped with special reinforcing devices (refer to Figure 8) 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 Figure 5), it is fabricated of high duty rolled steel with a thickness of 5 mm.
• The grate is one of the most thermally loaded parts of the heater, and the metal used for its fabrication meets all the specified requirements. Grill’D heater firebox door
• (5) is fabricated of steel and Schott Robax® thermal glass (Germany). An ash box with an ash drawer (4) is located under the firebox. The outer surface of the heater is covered with anti-corrosion heat-resistant enamel.
• IMPORTANT! The Manufacturer reserves the right to make modifications to the design of the heater that do not impair its consumer properties.

HEATER OPERATION

• It is necessary to operate the Grill’D heater in active combustion mode to set the temperature and during firing up. The principle heater operating time shall be in conservative mode.
• The door opening angle is sufficient for convenient loading of fuel and allows visual monitoring due to the availability of the thermal glass.
• Ash falls through the plates of the grate into the ash drawer, which allows convenient cleaning of the heater without interruption of burning. Stones in the stone heater are high-capacity heat accumulators, they shield the user from high-level infrared radiation and serve to generate steam when water is poured onto them.

COMMISSIONING

• IMPORTANT! Remove all packing elements , paper information labels, etc., prior to operation of the Grill’D heater.
• IMPORTANT! Prior to operation of the Grill’D heater, it is necessary to carry out a preparatory stoking.
• The preferable option for stoking is outdoors, away from combustible surfaces and materials, in compliance with fire safety measures and safe work practices. It is necessary to add on a portion of chimney stacks (2 meters) and load 3-4 logs into the heater firebox, start up a fire. Meanwhile, partly open the ash drawer (50 mm max), and upon development of a stable draft partly close it leaving a gap (10 mm max). Add firewood into the firebox as it is consumed. Carry out stoking until smoke and odor disappear.
• Compound for metal protection and volatile components of the heat-resistant enamel evaporate as a result of stoking.
• Note : Heat-resistant enamel can change tone on the most thermally loaded elements of the heater, which is not a manufacturing defect.
• IMPORTANT! Avoid the chance of mechanical impact and ingress of water on the paint coating of the heater during preparatory stoking.
• IMPORTANT! Carry out the heater installation and laying of the stones only after the complete cooldown of the heater.
• IMPORTANT! Installation of the heater and the chimney shall be carried out in accordance with SNiP 41-01-2003 (Construction Standards and Regulations) and by competent employees of a specialized construction and installation company only.

Procedure for the heater and chimney installation

1. Prepare the room and the place of the heater permanent operation taking into account the requirements of SNiP 41-01-2003.

2. Install the heater on the specified place in compliance with the requirements of SNiP 41-01-2003.

3. Perform the installation of the heater parts in accordance with Section 5 of this Manual.

4. Put the stones into the stone heater.
   Note : While laying the stones, It is necessary to ensure that they are as large as
   possible and that they fit closely to the entire surface of the stone heater. It is safer and more appropriate to use special stones, such as talcum peach, gabbro diabase, jade and others, intended for use in a bath house.
   IMPORTANT! It is prohibited to use halite to fill stone heaters.

5. Install the chimney and water tank (if any).
   Note : To avoid early boiling of water in the tank, we recommend that you install a pipe-mounted tank by Sferra Company with a volume of at least 50 liters. The volume of the tank will allow having both hot water and bath house ready almost simultaneously. The tank is installed on the heater outlet pipe.

6. Make sure that all heater elements and chimney system modules function normally (without firing the heater), and also make sure that there are no faults and discrepancies as follows:

• Missing parts;
• Visible damage of the heater body, parts;
• Ash drawer moves with difficulty.
• IMPORTANT! It is prohibited to operate faulty heaters and chimneys.
• IMPORTANT! The heater connection with the chimney or other structures shall be dismountable.
• IMPORTANT! For a better sealing of chimney modules with one another, it is compulsory to use a high-temperature sealant with an operating temperature of at least 1000оС.

HEATER OPERATING PROCEDURE

1. Prior to every firing of the heater proceed as follows:

   • Make sure that there is draft in the chimney.
   •  Make sure that there are no foreign objects, combustion Product residue from previous stoking in the heater firebox, ash drawer, or in the chimney.
   •  As required, remove all unnecessary and foreign objects from the firebox and chimney; remove ash from the ash box.
   • IMPORTANT! The use of cleaning logs (briquettes), homemade compounds creating high temperature in the heater firebox and chimney, is prohibited for the purposes of  burning the soot deposited in them.

2. Put 3-4 logs on the grate in such a way as to ensure free access of air to the combustion area (lay the firewood loosely; adjust the ash drawer gap to be 50 mm max).
   IMPORTANT! Allowing firewood to burn inside the heating flue is prohibited. Allowable length of logs is specified in Table 1.
   IMPORTANT! It is allowed to use only the fuel types specified in Section 2. Coniferous, resinous tree species (spruce, fir, pine, etc.) are not recommended as fuel. Construction and other materials containing chemicals, glue, etc., are strongly prohibited as fuel, namely: wood chipboard, wood fiber board, and others.
   IMPORTANT! Burning firewood with a moisture content of more than 25% in the heater leads to a rapid formation of soot deposits on the walls and flue of the firebox, as well as on the chimney walls.

3. Ignite the firewood loaded into the firebox.
   IMPORTANT! Lighter liquids, explosive or toxic substances, paints, solvents, gasoline, etc., are prohibited to be used for this purpose.

4. After heating up of the chimney and development of stable draft (usually after burning of the first load of firewood) the heater can be switched to conservative burning in order to maintain the temperature (partly close the ash drawer, leaving a gap of 10 mm max). Burning mode can be controlled via adjusting the position of the ash drawer (opening/closing), if necessary.
   IMPORTANT! After the firing of the heater and prior to development of a stable draft, emissions of minor volumes of smoke are possible.

5. When further stoking and loading of firewood is required, close the ash drawer, and 5 minutes after that open the door smoothly, without jerks. Load the firewood and close the door.
   IMPORTANT! In order to avoid early burnout of the firebox walls, It is allowable to carry out subsequent (upon the development of a stable draft) stoking of the heater to maintain temperature in the steam room in conservative mode only. It will also help to save the fuel.

6. The heater operation may be terminated after the entire load of firewood burns up. To do so, wait for the complete cooldown of the heater, remove ash from the firebox to the ash drawer, and then clean the ash box.

   • IMPORTANT! It is prohibited to use salt solution to generate steam during operation: pouring it onto the stone heater and the heater metal.
   • IMPORTANT! It is necessary to avoid ingress of water or salt solution onto the exposed metal parts of the heater both in the heated and unheated condition.
   • 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.

IMPORTANT! The firebox metal may become slightly deformed during operation, which is not a manufacturing defect provided the integrity of weld joints is preserved.
IMPORTANT! In case there is a hot water tank, the water shall be drained from the tank every time after termination of the heater operation, if the temperature in the room drops below + 5 ⁰С during interruptions of the heater operation.

9. SAFETY MEASURES

• IMPORTANT! It is prohibited to touch hot surfaces of the heater, stones, and chimney.
• IMPORTANT! It is prohibited to dry clothes, items, objects, firewood, bath brooms, etc., on the heater surface.
