APPLICATION

Grill’s 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 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 withoutrtificial 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.

Overall view and location of the heater main elements are shown in Figure 2. The firebox of Comet heater (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
Cometa Vega has two stone heaters: outer and inner ones (13). The space between the mesh (1) and outer walls of the inner stone heater is the outer stone heater (12 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 heaters , but also by means of air convection between the heater firebox, radiator (8), unprotective shield (7) through convection holes (Figure 9). Also, the protective shield screens high-level infrared radiation coming from the firebox walls as the heater is getting hot
Chimney connection pipe (2) 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 are equipped with a heating flue (3) allowing the heater to be stoked from the adjacent room, while the decorative screen (15) provides an

aesthetic appearance when arranging a wall passage and installing fire blocks. All heaters can bitonally 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, at the sometime the unburned Products of combustion (soot) also burn up. Additional heat is generated at a similar post-combustion of flue gases, increasing the heater 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 Rob ax® 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. Removable lid (10) allows accessing to the inner compartment of the stone heater and also serves as a fine steam restricting device
Water is supplied to the inner compartment of the stone heater through funnels (11). Given the stone heater lid is installed contiguously and the pressure is growing, the steam escapes through a nozzllocated on the lid and passes through the outer stones, which allows obtaining fine steam

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 ( partly open the ash drawer, 50 mm max) to set the temperature and during firing up. The principle heater operating time shall be in conservative mode (the ash drawer is partly open, 10 mm max)
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 thermal glass. The closed inner stone heater forms powerful steam generator, while the stones shield the user from high-level infrared radiation and serve as the source of the so-called. Ash falls through the plates of the grate into the ash drawer,  which allows convenient cleaning of the heater without interruption of burning.
Comet Vega allows obtaining several steam modes, namely

1. Fine steam mode is a mode for special ultralight steam obtained by pouring water through the funnels to the inner compartment of the stone heater, the stones in which are heated to temperatures above 400 ⁰С.
   

2. Russian bath house mode is achieved when water is poured onto the outer stone heater
   IMPORTANT! When pouring water onto the stones use a ladle with an extended handle (min 0.5 m) in order to avoid contact with the hot elements of the heater, and due to possible sudden emission of steam.

   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.

4. 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

5. 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 maintainperature (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.

6. 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 equant (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.

7. 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.

8. Drain the water from the integrated tank.
   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 that are both in the heated and unheated condition.
