9. Gas Pressure
Correct gas pressure is essential for efficient and
safe operation of the GF 160 DV IPI gas stove. It is
important that the correct pressure is established
at the time of the installation. Proper gas pressure
provides a consistent flow of gas to the appliance and
is instrumental in checking for gas leaks.
Pressure Test:
Attach a manometer to the
appropriate test point on the valve. See fig. 9.1.
The gauge connections are located on the front of
the valve. Connections are identified by:
A - for Manifold Pressure
(the amount of gas that
is coming out of the valve to the burner.)
B - for Inlet or Supply Pressure
(the amount of gas
coming to the valve.)
ALWAYS TEST PRESSURES WITH VALVE CONTROL

The appliance and its appliance main gas valve
must be disconnected from the gas supply piping
system during any pressure testing on that system
at test pressures in excess of 1/2 psig (3.5 kPa).
The appliance must be isolated from the gas
supply line by closing its individual manual gas
shut-off valve (gas cock) during any pressure testing
of the gas supply piping system that is equal to or
less than 1/2 psig (3.5 kPa).

10. High Altitude
Adjustment
The decreased atmospheric pressure of higher
altitudes affects heat value of gaseous fuels. Most
gas suppliers derate the gas intended for use at
elevations above 2000 feet. Check with your gas
supplier before performing derate adjustment to the
burner. If the gas supplier does not derate fuels, install
High Altitude Adjustment Kit 158059 for Propane and
Kit 158060 for Natural gas.

Orifice Sizes for 610-1370 meters (2000-4500 ft.):
Natural Gas: 2.30 mm
Propane: 1.40 mm
See data on the stove rating plate for additional
information. At higher altitudes, consult the local
gas distributor or the authority having jurisdiction
for proper rating methods. If the installer must
convert the unit to adjust for varying altitudes, the
information label must be filled out and applied to
the appliance at the time of the conversion.
INSTALLER: Fill out the appropriate information
and apply the high altitude conversion label provided
to the rating plate on the appliance. See fig. 10.1.
Derating Procedure
• Follow the steps for Burner Injector replacement
in the Fuel Conversion procedure on pages 14-15.
Use the injectors supplied with the adjustment kit.
Detailed instructions are also included in the kit.
• Conduct gas leak and gas pressure tests as
detailed in the preceding section of this manual.
• Conduct system check and flame picture
adjustments as specified on pages 23-24.
