Venturi Removal (PTS 17000000)
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 15,000 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 4-4)
Inner Distribution Ring Removal (PTS 17000000)
The inner distribution ring routes the gas from the sim-
mer orifice hood to the simmer holes located in the
burner head.
To remove the inner distribution ring, first, remove the
venturi. Then, lift the inner distribution ring from the
cooktop pan and discard the O-ring which is mounted in
a groove in the underside of the inner distribution ring.
The O-ring provides the seal between the cooktop pan
and the inner distribution ring. Now, unplug the igniter
lead wire and use a small piece of black tape to secure
the lead wire to the top pan.
(See Figure 4-5)
Igniter Removal (PTS 17000000)
The surface burner igniter is inserted down through the
inner distribution ring. It is held in place by a spring
and clip.
To remove the igniter, the burner head and venturi will
need to be removed. Now, lift the inner distribution ring
from the top pan, unplug igniter lead and tape it to the
top pan. Then, push the spring up slightly and use pli-
ers to remove the clip. Now, slide the spring off the
igniter and pull the igniter up and out of inner distribu-
tion ring. (See Figure 4-6)
WHEN REINSTALLING VENTURI USE TORQUE
WRENCH TO TIGHTEN TO 100 INCH/LBS. OVER
TIGHTENING WILL DAMAGE UNIT AND GAS
LEAKS MAY OCCUR.
TO ENSURE PROPER BURNER OPERATION, THE
O-RINGS
MUST
BE REPLACED ANY TIME THE
UNITS IS DISASSEMBLED FOR ANY REASON.
