Gas Pressure Adjustments

All GPD Series ovens are equipped with fixed orifices
and cannot be adjusted for gas flow: If necessary, pressure
adjustments can be made at the pressure regulator
(located on the combination gas valve).
A pressure tap is supplied with the unit and it is installed
on the manifold, downstream of the main valve. The gas
pressure must be checked when the unit is installed, to
ensure that the unit gas pressure is the same as specified
on the rating plate.
