Leak test:
1. Mix a 50-50 solution of water and dish
soap.
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, imme-
diately 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 consis-
tent flow of gas to the appliance and is instrumental 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 identi-
fied 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

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