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. High-alloyed corrosion-resistant steel is used
for the above heater elements in Pro models.
The effective design for heating up the stones and the steam room is due to numerous bends,
heat-conducting structural elements, which increase the heat dissipation area. 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 (except the mini models).
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.
2.3. 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: 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
