ADJUSTMENTS
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. e 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.
IMPORTANT:
All gas burners and pilots need sufficient air to
operate and large objects should not be placed
in front of this oven, which would obstruct the
airflow through the front.
Objects should not be placed on main rear of oven
while in use.

gas cock dial to “ON” position and set the thermostat
dial to the desired temperature. e oven burner flame
