Trouble Shooting The Oven Pilot Safety System
Automatic Pilot Valve
The automatic pilot valve is a protective device that allows
gas to flow to the oven burner only when the pilot burner is
burning. (This is used on GARLAND ovens and ranges to have
safe lighting provisions provided by the flow interrupter that
will not allow gas to flow to the oven burner while the red
button is depressed.)
GARLAND has used two different types of pilot safety valves.
On the 280 Series the valve used up to July 1988 was the
Robertshaw TS-11J. From July 1988 to September 2000, the
Johnson BASO H15HQ-6 valve was being used. The Heavy
Duty Series used the Robertshaw TS-11J up to October 1990;
from then on the Johnson BASO H15HQ-6 valve was being
used. Figure 1 showing the TS-11J and Figure 2 showing the
Johnson BASO H15HQ-6. Garland has since started using the
Robert Shaw TS-11J valve on all Garland and US Range using
this system.

2007 (Sit Control) X, U, & G
Series Safety Systems
Garland’s new Restaurant ranges contain a gas control
system enclosed in one component; the Sit Control.
The oven/griddle pilot safety system is an internal
subcomponent of the control. If, during a normal safety valve
system check, the safety valve/coil is found to be weak or
inoperative,
the complete control must be replaced .
Thermoelectric
Flame Failure Device
Note: This control uses a different adapter, than the one
described below to complete a Closed circuit test .
Thermocouple replacement.
A thermocouple nut should be started and turned all they
way in by hand. An additional quarter turn with a small
wrench will then be sufficient to seat the lock washer
and maintain adequate contact. A too loose or too tight
connection of the thermocouple nut to the automatic
pilot valve can prevent the thermocouple from activating
the valve. A visual examination of the thermocouple lead
should be made to make sure that there are no cracks or
ruptures. Every effort has been made to insure trouble-free
performance of this system with a minimum of service.
To Test Magnet Assembly And
Thermocouple Operation
Heating the thermocouple tip by the pilot flame produces an
electric potential that is used to energize the magnet that,
in turn holds open the main and pilot valves. When the pilot
is “OUT” or improperly adjusted, insufficient heat is applied
to the thermocouple tip to produce adequate electrical
generation that results in the control shutting itself off.
