Section description
The casing of the section is made of aluminium frame sections and 50
mm thick thermally insulated panels.
The air is heated by flowing around the combustion chamber and its
tube plate.
A flange for the burner mounting is situated on the front (service) side
of the heat exchanger. The flue gases are drawn off via the chimney
outlet (optionally on the rear side of the section). Sections are manu-
factured in two versions - either with or without the bypass. The bypass
version is equipped with a damper to regulate air flow. Furthermore,
the gas heater section is provided with a condensate drain outlet (1/2“
pipe).
This section can be delivered for indoor as well as for outdoor use.
The burner and triple safety thermostat of the outdoor version are
protected by covers.
A burner operated in an outdoor environment up to -20 °C must be
provided with a heating cable switched by the thermostat. As standard,
this set is included in deliveries marked as TKW 53 for burners WG 10,
WG 20, or as TKW 88 for burners WG 30, WG 40.
A burner operated in an outdoor environment from -20 °C to -40°C
must be equipped with a special heated cover of the burner and a
burner flange for the external air inlet
Burner closed heated cover installation
The external air inlet to the burner's extension is made from a Spyro
hose. An aperture in the burner cover for the hose must be created
in the appropriate location; the hose must be sealed in this aperture.
Inlet air must come from the heated room.
The SK 3102.000 300 W heating equipment will be attached on the
heater panel under the burner valve block using a holder (enclosed, in-
cluding 4 screws). Electrical connection will be made using a seven-pin
connector at the burner. The heating power supply is ensured directly
from the burner; therefore, the burner's "L" terminal must always be
under voltage.
The thermostat of the burner cover is set to 5 °C. If the cover's
temperature drops below the pre-set temperature, the heating is
switched on.
Connection of Gas Heater
The XPTG gas heater section must be connected to the air duct via
a dilatation insert heat resistant up to 200 °C. The gas-flue ducting
must comply with all applicable directives and standards of the state
of installation (for CZ - ČSN 73 4201 and ČSN 73 4210), and must be
performed by a specialized provider. For information on installation,
commissioning and inspections of the gas indirect heater and burner,
refer to the special Installation and Operating Instructions which are
included in the accompanying documentation of the air-handling unit.
Safety and control elements delivered with the section must be con-
nected to ensure proper, reliable and safe operation.
