Impinger X2 –Operator Manual 19
Review the specification sheets for maximum and minimum allowable pressures and hourly
BTU consumption.
Consider all gas-fired appliances at the site when sizing incoming gas lines. Insufficient, intermittent or
excessive gas pressure will negatively affect the oven’s performance.
IT IS THE CUSTOMERS RESPONSIBILITY TO ADEQUATELY SIZE THE INCOMING GAS LINE. Contact
your gas supplier for assistance. Keep in mind that capacity of the appliances gas supply is a function of
incoming line diameter, length of line from the meter and gas pressure. You must also consider any other gas-
fired appliance in sizing your incoming gas line.
MINIMUM GAS REQUIREMENTS (UNITED STATES, CANADA and AUSTRALIA)
While your gas supplier may have different recommendations on gas supply specifications, we require the
following minimum specifications in order to achieve optimum Lincoln X-2 Oven performance:
Natural Gas Propane
Gas Line Diameter with piping run of up to 150 linear feet. 2” NPT 1.5” NPT
Consult factory for piping run in excess of 150 feet.
Dynamic Pressure (measured at the oven with all gas-fired
8-14” WC 14” WC
appliances in operation)
Maximum Dynamic Pressure
DROP (measured at the 1.0” WC 1.0” WC
oven with all gas fired appliances in operation)
ABSOLUTE
MINIMUM DYMANIC PRESSURE 8.0” WC 13.0” WC
Minimum Regulator Size (BTU per Hour)
Single Oven 300,000 300,000
Double Ovens 600,000 600,000
Manifold Pressure
3.5” WC 10” WC
For Lincoln X-2 Ovens to provide optimum performance, the burner must receive at least the minimum dynamic
pressure with no more than the maximum dynamic pressure drop. Dynamic pressure should never fall below the
minimum value. The installation of a 1/2- pound, one pound, or two pound gas supply system will often solve the
gas pressure and supply problems and should be specified prior to oven installation. See the previous page for
an illustration of a low-pressure vs. high-pressure gas delivery system.
Please contact your local gas supplier prior to oven installation to make certain your facility meets or exceeds
these minimum requirements.
Consult local building codes for specific gas fittings required. All gas line fittings, connectors and valves must be
American Gas Association design certified. A manual gas shutoff valve must be installed so it is accessible
when the oven is in the installed position.
AUSTRALIA to adhere to AG 5601-2004 and 4563-2004 Gas
Installation Code.
UNITED STATES, CANADA and AUSTRALIA
During any pressure testing of the gas supply system, the oven and the shutoff valve must be disconnected
from the gas supply at pressures in excess of 1/2 psi (3.45 kPa). Pressure testing performed at 1/2 psi (3.35
kPa) or less requires closing the manual shutoff valve on the oven to isolate the oven components from the gas
supply system.
AUSTRALIA to adhere to AG 5601-2004 and 4563-2004 Gas Installation Code.
For conversion of ovens in the field from Natural Gas to Propane or from Propane to Natural Gas, an Authorized
Service Agent must be contacted to perform the work.
