Gas Pressure
Correct gas pressure is essential for efficient and
safe operation of the GF 200 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. 34. 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
KNOB SET ON HIGH.

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
exceeds pressures of 1/2 psig (3.5 kPa).

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 157675 for
Propane and Kit 157676 for Natural gas.
U.S & Canada per
ANSI Z21.88-2009 • CSA 2.33-2009, CAN/CGA 2.17
At 610-1370 meters (2000-4500 ft.), the orifice size is
#46 for Natural Gas and #56 for Propane. See data
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. 35.
Derating Procedure
• Follow the steps for Burner Injector replacement
in the Fuel Conversion procedure on pages 17-18.
Use the injector supplied with the adjustment kit.
Detailed instructions are also included in the kit.
• Conduct gas leak and gas pressure tests as de-
tailed the preceding section.
• Conduct system check and flame picture adjust-
ments as specified on pages 22-23.
