Figure 4. Gas Inlet
Install the gas pressure regulator with gas
flowing as indicated by the arrow on the regula-
tor. The arrow must be pointing in toward the
unit. Use pipe compound or thread sealant and
carefully thread regulator to pipe so that there is
no cross threading, etc., which could cause leak-
age.
1. Apply wrench only to the flat areas around the
pipe tapping at the end being threaded to the
pipe to avoid possible damage to the regulator
body which could result in leakage.
2. Connect the gas supply line from the service
gas shutoff valve to the inlet side of the gas
pressure regulator using 3/4" pipe. Avoid kinks
or sharp bends that could restrict gas flow.
NOTE: If flexible or semi-flexible connectors
are used, a CE listed flexible connector
with an I.D. equal to 3/4" pipe must be used.
WARNING!
DO NOT USE A DOMESTIC TYPE
FLEXIBLE GAS CONNECTOR.
3. Turn gas shutoff valve on and carefully check
for gas leaks immediately. Do this before
attempting to operate the broiler.
WARNING!
Test all pipe joints for leaks before operating
broiler. This includes all gas connections
that may have loosened during shipment.
Use a rich soap solution (or other accepted
leak tester) around all pipe connections and
all other joints. Do not use an open flame.
Absolutely no leakage should occur, other-
wise there is a danger of fire or explosion
depending upon conditions. Do not use unit
leakage is detected.
After piping has been checked for leaks, all pip-
ing receiving gas should be fully purged to re-
move air.
GAS PRESSURE REGULATOR
WARNING!
THE BROILER(S) IS/ARE DESIGNED FOR
USE WITH A GAS PRESSURE REGULATOR.
THE REGULATOR(S) SUPPLIED WITH THIS
UNIT MUST BE USED.
FOR G20 GAS:
This gas pressure regulator is
factory adjusted for 15 mbar manifold pressure.
The rated inlet pressure to the regulator is 3.45
kPa.
FOR G31 and G30 GAS:
This gas pressure
regulator is factory adjusted for 25 mbar mani-
fold pressure. The rated inlet pressure to the
regulator is 3.45 kPa.
The broiler is equipped with fixed orifices for use
with a manifold pressure of 15 mbar for G20 gas
and 25 mbar for G31 and G30 gas.
Position the gas pressure regulator outside the
broiler as near to the unit as possible.
CAUTION: The gas pressure regulator must
be located out of the heat zone to prevent
damage to the regulator.
The whole of the gas installation, including the
meter, should be inspected, purged, and tested
for soundness in accordance with the codes of
the country of destination.
