SERVICE
IMPORTANT
WHEN SERVICE IS NEEDED, CONTACT A
LOCAL SERVICE COMPANY, DEALER, OR
FACTORY TO PERFORM MECHANICAL
MAINTENANCE AND REPAIRS. THESE
INSTRUCTIONS ARE INTENDED FOR USE
BY COMPETENT SERVICE PERSONNEL.
CAUTION
TURN OFF GAS SUPPLY WHEN SERVICING
GAS CONTROL SYSTEM.
PILOT SAFETY VALVE
Model H15HR is an automatic 100% pilot safety
which provides complete gas shut off in the
event of a pilot failure. The safety valve is held
closed by spring pressure. When red button is
pushed by hand, gas flows to pilot. Pilot heats
thermocouple creating a very small amount of
electricity. This energizes a magnetic coil under
the red button and holds the valve open, permit-
ting gas to flow to main burner and pilot without
holding pressure on red button. In the event of
pilot failure, the flow of electricity will stop and
spring will stop flow of gas to both pilot and ov-
en burner.
NOTE: When replacing thermocouple, make
sure that valve is clear of debris to allow for
clean connection.
NOTE: When servicing a unit with a defective
pilot safety valve, the whole valve should be
replaced instead of just the magnetic head.
OVEN PILOT BURNER
PILOT SERVICE IN THE EVENT OF PILOT
FLAME FAILURE
1.
If pilot flame burns yellow, clean pilot orifice
and pilot burner to insure a steady blue
flame. The pilot burner orifice can be cleaned
by washing in a solvent and / or blowing out
with air.
2. Flame must surround the thermocouple tip
approximately 1/2‖. If the closed circuit check
shows thermocouple output is greater than 8
millivolts and pilot will not remain lit when
reset button is released, replace pilot safety
valve.
3. Thermocouple lead connections must be
tight , clean, and free of grease. The
thermocouple nut should be started and
turned all the way by hand. An additional
quarter turn with a small wrench will then be
sufficient.
