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. Cleanout
cap (7) closes the opening, which serves to clean the heater flue channels of
foreign objects, and soot accumulated on the inner walls, etc. For additional
information on the heater maintenance, refer to Section 11. MAINTENANCE.
IMPORTANT! The Manufacturer reserves the right to make modifications to
the design of the heater that do not impair its consumer properties.
