INSTALLATION

Continued

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 12).

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  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 bags of ash bed material (vermicu

-

lite) and spread it evenly across burner 
pan  to  the  top.  You  may  overflow  front 
and sides of pan to cover the 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. Grate should 

“lock” into place over corners of pan (see 
Figure 15).

2.  Place  one  of  the  bottom  logs  on  grate 

and slide forward against front grate bars. 
Repeat for other side (see Figure 16).

3.  Place smaller top logs onto bottom logs 

(see  Figure  17).  Leave  as  much  open 
space between logs as possible to mini

-

mize flame impingement and sooting. 

 

Note: Logs may chip if they are handled 
roughly  or  if  hit  together  while  being 
placed.
