TESTING BURNER FOR LEAKS
1. Generously apply soapy solution to all
connections.
WARNING: Never check for
gas leaks with open flame.
2. Light the burner with the shutoff valve no
more than half open and holding a match
slightly in front of the pan (see Lighting
Instructions, page 11).
3. Inspect all connections for bubbles, raw
gas odor, or flame from any area other than
the burner (leaks). If leaks are detected,
shut off the gas valve immediately. Tighten,
or reassemble the loose connection(s)
using pipe joint compound until burner
system is leak free.
4. When the burner is tested and leak free,
observe the individual tongues of flame
on the burner.
Note: The burner design includes more
ports on the outside of the bar. Make
sure that all ports are clear and produc-
ing flame evenly across the burner. If
any ports appear blocked, clear them by
removing the burner manifold and ream-
ing the ports with a modified paper clip or
other suitable tool.

5. When finished testing, turn the gas shutoff
valve OFF to extinguish all flames.
ADDING PAN MATERIAL
1. Open the bag of ash bed material (vermicu-
lite) and spread it evenly across the burner
pan to the top. You may overflow the front
and sides of the pan to cover the entire
pan. Do not cover valve or inlet fitting.
2. Open the glowing embers and evenly
cover the ash bed material (vermiculite)
in the burner pan.
INSTALLING THE GRATE AND LOGS
1. Place the grate over the burner pan where
the two outer horizontal supports on the
grate fit into the two pan positioning notches
in the rear vertical edge of the pan.
2. Slide the two rear log grate steps over the
two outer horizontal supports on the grate
as shown in Figure 12.
3. Place the back log on the grate onto the
grate steps (see Figure 13, page 10).
4. Place the front log(s) on the grate and
slide forward against the front bars on the
grate (see Figure 13, page 10).
5. Place the smaller top logs onto the bottom
logs (see Figure 14, page 10). Leave as
much open space between logs as pos-
sible to minimize flame impingement and
sooting.
Note: Logs may chip if they are handled
roughly or if hit together while being
placed.
