Jet Holder Removal (PTS 17000000)
The jet holder is mounted to the burner support on the
bottom of the burner box. The main burner orifice is
threaded into the jet holder as well as the venturi.
To remove the jet holder, remove the grate(s), burner
head(s) w/cap(s), venturis, igniter lead wires, inner dis-
tribution ring(s), burner pan and outer distribution rings.
Then, disconnect the flexible gas tube that is mounted
to the jet holder. Now, extract the screws which secure
the jet holder to the burner support and lift the jet holder

The deflector shield protects the spark modules and
wiring from spillage that may occur.
To remove the deflector shield, remove the grate(s),
burner head(s) w/cap(s), venturis, igniter lead wires,
inner distribution rings, burner pan, outer distribution
rings and jet holders. Now, extract the screws which
secure it to the burner support and remove. (See
