PREHEATING
1. Turn burner valves to the HI position and allow 30-35 minutes for preheating. After this period of
preheating time, grid temperatures should be in the ideal range for the most favorable cooking
results (around 600°F).
2. Turn burner valve to the LO position (which is preset at the factory) to maintain grid temperatures
between 575°F and 625°F, which will provide ideal cooking conditions and the optimum finished
product.
DO NOT leave the burner valves set in the HI position, except for cleaning grid grates, for any extended
period of time beyond the recommended preheating time; it will produce grid temperatures in excess
of 1000°F. These temperatures will result in unfavorable cooking conditions, excessive carbonization
of grease on the grid and a poor tasting product. Excessive temperatures will also lead to premature
failure of the radiants and grid tops.
GRID TOPS
The GHMCB34 and GHMCB51 are equipped with reversible grids (see Fig. 4). The grids may be
placed on one side so that they are sloped and lifted away from the burner flame, or placed flat on the
broiler so that they are close to the burner flame.
WARNING: GRID TOPS ARE HOT. USE CARE WHEN CHANGING GRID TOP POSITIONS.
GREASE COLLECTOR TRAY
Periodically check and empty the grease collector tray (see Fig. 4) to avoid overflow of grease. To
remove tray, pull grease tray handle straight out, empty and replace tray.
CLEANING
Burner Radiant
Clean the burner radiants daily with a good wire brush. The radiants may be cleaned in place over the
burners, or they may be removed for a more thorough cleaning.
Burner Performance
If after a period of satisfactory operation burner flame characteristics should change or length of flame
should be reduced, either the mixer opening, the gas orifice or the burner ports have become restricted.
Clean burners every 60 days or more often if required. To clean burners, boil in a strong solution of
lye water for about 15 minutes. Ports can be opened by hand with a sharp pointed metal instrument
or a proper sized drill bit.
Enamel Finished Surface Parts
Clean using a cloth with detergent solution. Rinse thoroughly and wipe dry with a soft clean cloth.
