Crown Verity CCB-60 - Manual (Page 15)

WHAT TO LOOK FOR
Out of propane? Improper lighting procedures? Is
cylinder valve turned on? Regulator assembly not fully
tightened to cylinder valve? Gas piping system is full of
air - Bleed out system, wait five minutes and repeat
lighting procedures. Large black nut on cylinder
connector is cracked or has been overheated and is
not making a gas tight seal inside cylinder valve -
Replace regulator and hose assembly.
Has charbroiler been sufficiently preheated before
turning to low? Is the venturi properly seated over the
orifice? - Inspect both venturis and burner holes for
obstructions and check for proper air shutter opening
on venturis.
Leaving burner valve open before opening cylinder valve
or leak in system causing flow control device to
activate. - Follow proper lighting sequence or correct
leak in system. Inspect venturi for obstructions and
alignment. Make sure burners are clean.
Immediately shut off gas supply at cylinder valve. Allow
charbroiler to cool. Check venturis and orifices for
obstructions. (See fig. 2, pg. 3.) Excessive grease
build-up around control valves has caused a grease
fire. - Clean charbroiler. If problem persists, contact
qualified service person.
Has grease tray been installed? Is charbroiler level?
Excessive grease build-up - Clean unit.
The cylinder pressure has dropped below operating
pressure due to freeze-up. Long periods of “full open”
operation will cause this. Remedy: exchange cylinder
with a new full one.
Overload of fatty meat. - Clean charbroiler. Add water
to grease tray(s) (Level unit first). See tips and
techniques page 11.
