SOLELY INTERIOR
installation is possible,
• for the sake of appropriate efficiency the position and the high of installation has to be carefully defined,
•
the mounting of appliance can be executed by cantilever respectively suspension
•
the appliance has to be placed in that way that its every part be accessible�
WARNING! The appliance can only be operated by gas defined on the data board of appliance !
The nominal values of gas-supply pressure:
• in case of natural gas: 25 mbar ( min. 20 mbar – max. 60 mbar )
• in case of Propane gas: 50 mbar
The allowed maximum pressure of gas-supply: 60 mbar!
WARNING! If the pressure of gas-supply is higher than 60 mbar in that case the using of pressure
regulator is indispensable because the max. allowed pressure of double-closed magnetic valve is:
Pmax = 60mbar
The pressure regulator can be installed before each appliance or centrally namely one piece into the gas-supply pipe� In case of unique
solution - namely there is pressure regulator before each appliance – before every pressure regulator, in case of centrally mounted
pressure regulator before pressure regulator and each appliance
MUST BE INSTALLED GAS FILTER
to be able to avoid the blocking
of appliance’s gas magnetic valves, which can be caused by possible contamination settled in the supply pipes�( despite blowing out of
pipes it can be present)
The connection to the gas-supply pipe must be from above or side (Pic� 8) because in case of bottom connection the possible contamina-
tions settled on the pipe can influence the proper operation of equipment.
Appropriate connection
Incorrect connection
8. picture: Connection to gas-supply pipe
The gas connection must be accomplished by flexible gas pipe. Use such flexible gas pipe for connection, which renders 100 mm free
moving possible. The flexible gas pipe must be mounted free from torsion! Recommended to apply gas connection set (flexible gas
pipe,gas filter,1/2” or 3/4” shat off valve) marketed by PAKOLE Ltd.(Pic. 9). If there is installed pressure regulator per appliance then it
must be mounted between the gas filter and flexible gas pipe.
