Gas connections.
The gas supply (service) line must be the same size or greater than the inlet line of
the appliance. ASBER appliances use a ¾” NPT inlet.
Pipe joint compound must be resistive to Natural or LP gas.
For equipment using propane gas do not install supply lines with a diameter less than ½ under any
circunstances.
All connections must be tested with a soapy water solution before lighting any
pilots.
After all pipe connections have been checked for leaks, fully purge gas pipes to remove air.
The appliance shall be connected to the fuel gas for which it was designed. No attempt shall be
made to convert the appliance from the gas specified on the rating plate for use with a different
gas without consulting the installation instructions, the serving gas supplier, or the appliance
manufacturer for complete instructions.
2.5.1 Manual shut off valve.
This installer supplied valve must be in the gas service line ahead of the appliance regulator in
the gas stream and in a position accessible in the event of an emergency.
2.5.2 Pressure regulator.
Commercial cooking equipment must have a pressure regulator on the incoming service line for
safe and efficient operation; the gas pressure regulator supplied by ASBER must be installed at
the gas inlet of each piece of equipment.
The gas pressure should be set at 5” W.C. (Water Column) (0.8 kPa) for natural gas and
10”W.C. (2.75 kPa) for propane gas.
Prior to connecting the regulator, check the incoming line pressure, as these regulators can only
withstand a maximum pressure of ½” PSI (14”WC). If the line pressure is beyond this limit, a
step down regulator will be required.
The arrow shown on the bottom of the regulator body shows the gas flow direction, it should
point downstream to the appliance. The BLUE air vent cap on the top is part of the regulator
and should not be removed.
Any adjustments to the regulator should be made by qualified service
personnel only with the proper equipment.
