Leak test:
1.Mix a
2.Light appliance- see lighting instructions on the inside back cover of this manual or on the stove’s rating plate.
3.Brush or spray all joints and connections with the soapy water solution.
4.If bubbles appear at any connection or seam or a gas odor is detected, immedi- ately turn gas control knob to the OFF position.
5.Tighten or reconnect the leaking joint and retest for any gas leaks.
Gas Pressure
Correct gas pressure is essential for efficient and safe operation of the GF 300 BV 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 instru- mental in checking for gas leaks.
Pressure Test: Attach a manometer to the appro- priate test point on the valve. See fig. 19. The gauge connections are located on the front of the valve under the On/Off/Pilot- knob. Gauge connections are identified by:
E - for Inlet or Supply Pressure (the amount of gas coming to the valve.)
A - for Manifold Pressure (the amount of gas that is coming out of the valve to the burner.)
ALWAYS TEST PRESSURES WITH VALVE CONTROL KNOB SET ON HIGH.

INLET GAS PRESSURES (inches water column)
| MIN | MAX |
NATURAL GAS | 5.0 | 7.0 |
PROPANE | 12.0 | 14.9 |
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
