TESTING BURNER FOR LEAKS
1. Generously apply noncorrosive leak de-
tection fluid to all connections.
WARNING: Never check for
gas leaks with open flame.
2. Light burner with shutoff valve no more
than half open and holding a match 
slightly in front of pan (see Lighting In-
structions, page 14).
3. Inspect all connections for bubbles, raw
gas odor, or flame from any area other 
than burner (leaks). If leaks are detected, 
shut off gas valve immediately. Tighten, 
or reassemble loose connection(s) using 
pipe joint compound until burner system 
is leak free.
4. When burner is tested and leak free,
observe individual tongues of flame on 
burner. 
Note: Burner design includes more ports 
on the outside of the bar. Make sure that 
all ports are clear and producing flame 
evenly across burner. If any ports appear 
blocked, clear them by removing burner 
manifold and reaming ports with a modi-
fied paper clip or other suitable tool.
5. When finished testing, turn gas shutoff
valve OFF to extinguish all flames.
ADDING PAN MATERIAL
1. Open bag of ash bed material (vermiculite)
and spread it evenly across burner pan to 
top. You may overflow front and sides of 
pan to cover entire pan and connecting 
hardware. Do not cover GA9050A-1 or 
GA9150A valve.
2. Open glowing embers and evenly cover
ash bed material (vermiculite) in burner 
pan.
INSTALLING GRATE AND LOGS
1. Place grate over burner pan where two
outer horizontal supports on grate fit into 
two pan positioning notches in rear verti-
cal edge of pan.
2. Slide two rear log grate steps over two
outer horizontal supports on grate as 
shown in Figure 15.
3. Place back log on grate onto grate steps
(see Figure 16, page 13).
4. Place front log(s) on grate and slide
forward against front bars on grate (see 
Figure 16, page 13).
