Checking the Connected Gas Pressure (Nominal Pressure)
Close the gas cock where the gas line is connected to the machine and attach a manometer
to the tap (allen screw) on the gas cock. With the manometer connected, open the gas
cock and ignite the burner. Along with all other gas appliances at the location in
operation, measure the gas pressure.
This ideal operating pressure should be 5.5" W.C. for natural gas and 11" W.C. for LPG.
If the pressure is too high and can not be adjusted downward, check to see if the proper
adjusting spring is in the regulator. If this is correct, the regulator membrane may have been
ruptured by excessive gas pressure and may have to be replaced. Do not operate the rotisserie
if the gas pressure exceeds the ideal values.
If the operating pressure is below 5.5 " W.C. for natural gas or below 11 " W.C. for LPG, the
unit should not be operated. The pressure should be adjusted to the ideal setting using the
pressure regulating screw on the pressure regulator.
If the pressure is too low and can not be adjusted upward, also check the regulator. If this is
operating properly, verify the pressure coming out of the main gas meter. Another typical
source of this pressure problem is that the gas line (pipe) diameter leading up to the unit is
too small. If the gas line is under-sized, the appropriate pressure may not be reached. Do not
operate the unit if the pressure falls below the ideal values.
If the measured pressure is still below the ideal range and it is not possible to resolve the
problem, the local gas company or gas supplier should be contacted so that they can resolve
the problem.
After the pressure has been set, close the gas cock once again, remove the manometer, seal
the gas tap, and then re-open the gas cock.
WARNING: After an installation, repairs, or maintenance, make sure that there are
