the Building Code.
•Check the pipes diameters in order to ensure sufficient supply to all the gas-heated
devices. To avoid excessive pressure drop, install the device while maintaining
similar conditions.
•Connection to the gas distribution grid should be made of metallic, hard or flexible
material with the use of tubes of proportional diameter. Insert a gasket appropriate
for gas products.
•Make sure that flexible tubes do not pass on or near hot surfaces, are not subject to
strain or pressure and have no contact with sharp edges or other objects which
might damage the tube.
•A certified gas shut-off valve must be installed in an accessible place between the
gas distribution grid and the device, to allow for cutting off the gas supply at any
moment, if necessary.
•Check if the gas cylinder (if attached) is properly set and secured and whether it
stands in a dry place.
•Before the installation, make sure that the device is set for gas and pressure
available at the installation site (see rating plate on the device and packaging). If the
factory settings do not match, the device must be switched to another gas type
(Chapter 5.1.5 „Switching the device to another gas type / required settings”).
•After the installation of the gas stock-pot stove, a leak test of all gas pipes should be
performed with the use of water with soap or leak detection spray.
5.1.4 Output control
Checking nominal heat output
•During the initial installation, the gas installer must check the nominal heat load of
the device, as well as carry out maintenance and if necessary – switch the device to
another gas type.
•Never try to increase the output or nominal heat of the device provided by the
manufacturer.
•Control the nominal heat load with the use of gas meter and stopwatch. Measure
precisely the volume of flowing gas per unit of time, consumed by the device at the
maximum output.
•Compare the readouts with the consumption data in Chapter 4.2 „Technical data“.
Tolerance of ± 5 % is allowed.

- 42 -
Delivery pressure control
•If the measurements show bigger deviations, carefully check the diameter and quality
of embedded nozzles, as well as a delivery pressure. Delivery pressure should
comply with the following values:
20 mbar for gases of second group (natural gas) G20/G25
50 mbar for gases of third group (butane / propane) G30/G31
•Delivery pressure may be measured on the working device with the use of a liquid
manometer (e.g. U-tube manometer scalable to min. 0.1 mbar). Follow these
instructions:
-loosen the sealing screw (C) of the pressure control connector (B)
(Fig. 3, p. 13);
-set the manometer;
-switch the device on according to the instructions in
chapter 5.2.2 “Device switch on/off“.
-check the delivery pressure:
-remove the manometer;
-re-tighten the sealing screw (C) ;
-perform a leak test.
5.1.5 Adjustment to another gas type / required settings
•The device is factory-tested and prepared to work with the type of gas provided
on the rating table (liquid gas).
•If factory settings of the device do not match the gas type available at the
installation place, they must be changed accordingly. Special nozzles (marked
with hundredths of a millimeter and included in the delivery) and settings are
required for switching the device to natural gas.
CAUTION!
Such adjustment may be performed only by a qualified gas installer, while
taking into account technical data, through the replacement of the main burner
nozzles and the control valve, as well as changing of the resulting settings.
a) Nozzle replacement (Fig. 4, p. 15)
Remove the cast iron ribbed support, burner and Venturi tube from the device.
Unscrew the nozzle using a 7 mm wrench, then mount a new nozzle (F).
