Burner Head with Cap Removal
The burner head consists of a top and bottom layer of
holes. When main burner heat is required, the gas
travels through the main burner orifice hood (mounted
to the jet holder), then through the venturi to the burner
head and then out the top layer of holes. When simmer
heat is required, the gas travels through the simmer ori-
fice hood (located on the side of the outer distribution
ring), up through the outer portion of the inner distribu-
tion ring, then to the bottom layer of holes on the burner
head. To remove the burner head, remove the burner
grates and lift the burner head off of the inner distribu-
tion ring
(See Figure
4-1).
Venturi Removal
The brass venturi mounts through the inner distribution
ring and is threaded to the jet holder. There are two
sizes of venturi. One size is for the large 12,000 BTU
burners. The other size is for the smaller 9,200 BTU
burners. The threads on the venturi are different for the
large and for the small. They will only thread back into
the appropriate sized jet holder. To remove the venturi,
first remove the burner head with cap and then extract
the venturi using a 7/8 inch socket wrench from the jet
holder
(See Figure
4-2).
WHEN REINSTALLING VENTURI USE TORQUE
WRENCH TO TIGHTEN TO 100 INCH/LBS. OVER
TIGHTENING WILL DAMAGE UNIT AND GAS
LEAKS MAY OCCUR.
