Low Heat
One of the main reasons for low heat is the lack of
proper spacing between the briquettes. Briquettes that
are butted together will block heat from reaching the
SEAR GRID
®
. See Page 8 for proper briquette spacing.
As mentioned above, a tripped flow limiter will
cause a small flame and low heat (See Page 14) on an
LP grill.
On natural gas grills, the main reason can be a
lack of the proper incoming pressure. Long pipe lines
or undersized piping (See Page 17) will cause low
pressure. The best way to know is to have the pressure
checked at the orifice with a manometer.
Burner Will Not Ignite—
No Gas Flow
If your burners will not light even with the use of a
match, then there must be some type of blockage to the
gas flow. The obvious item to check is to make sure
your LP tank valve is open (and the tank has gas in it)
or that the natural gas main shutoff valve is open.
Blockage of the orifice (See
Spider Guards
in the
Maintenance
section Page 33) is another reason
that could prevent gas flow. If you have an LP gas
grill and can not light any of your burners even with
a match, then it is possible that the plastic nut on
the tank fitting is not fully tightened. Check that it
is completely engaged.
For LP grills it is always a good idea to try a
different LP cylinder to rule out the tank as a source
of the problem.

Burners with Poor Flame
Check to be sure burner ports, shutter, end of
the burner (venturi) and orifice(s) are free of any
obstructions. (See cleaning instructions in
Maintenance
section — Page 33.)
Also, if your grill has been stored over a prolonged
period of time, check to make sure no spiderwebs have
been formed in the shutter end of the burner (venturi)
or over orifices. (See
Spider Guards
— Page 36.)
If popping or flashback should occur when flame is
extinguished, see
Burner Shutter Adjustments
on page 26.
On an LP grill, if an extremely low flame is present,
the flow-limiting device may have activated. (See Page
14.) To reset the flow limiter, close the grill valves, wait
about 5 seconds and then open the grill valves to start a
proper ignition sequence.
