ORIFICE ENGAGEMENT
4. Place lower grill casting on top of pedestal lining
up four bolt holes (located just above air vents) with
cage nuts just installed (see Fig. 5). Then insert the 4-
1/4" X 20" X 1 1/4" hex bolt each with a 1/4" flat
washer and 1/4" lock washer. When all four are in
place, tighten bolts securely.
At the end of each valve there is a tiny gas opening
known as an orifice. Gas exits the orifice and enters
the venturis where it mixes with air. The proper
mixture of gas and air produces a clean blue flame
with slight yellow tips from the burner.
BE CERTAIN THAT ORIFICES ARE ENGAGED
INTO THE BURNER VENTURIS (see Fig. 7). Proper
orifice engagement should be 1/4" to 3/8" into the
venturis.
FAILURE TO PROPERLY ALIGN THIS
CONNECTION MAY CAUSE A FIRE AND
RESULT IN DAMAGE TO YOUR GRILL.

5. Install burner assembly into lower casting by
inserting venturi tubes through lower casting (see
Figure 7
Proper orifice engagement
Fig. 6). The burner has a spring clip to secure the
burner in the casting. Be sure that the burner "snaps"
into position.
7. Insert feed line through the rear of the pedestal
with the bent end coming through to the front of the
pedestal. Attach 3/8" female brass flare nut to valve
assembly.
6. Attach control panel to grill head. You will note
that both of the bolts attached to the control panel
have two nuts on them. Remove plastic thread
protectors at the end of bolts and discard. Remove
the top nut leaving the remaining nut (closest to the
back of the control panel) to act as a spacer. Insert
3/4" bolts (pre-assembled on control panel) through
holes on front of lower casting. Be sure you line up
the venturis over the valve stems protruding from the
back of the control panel (see Orifice Engagement).
NOTE: BE CAREFUL NOT TO CROSS THREAD
THIS FITTING. This is a brass to brass flared fitting,
IT WILL NOT REQUIRE ADDED SEALANT OR
TEFLON TAPE. Once properly in place, tighten both
control panel and feedline securely.
Attach nuts and leave slightly loose at this time to
allow for adjustment (see Fig. 6). If the venturis do
not align over the valve stems properly, they can
be rotated slightly for proper adjustment.
