Brinkmann 7741 Series - Manual (Page 17)

BURNER ASSEMBLY/MAINTENANCE
• Although your burners are constructed of stainless steel, they may corrode as a result of the extreme
heat and acids from cooking foods. Regularly inspect the burners for cracks, abnormal holes, and other
signs of corrosion damage. If found, replace the burner.
• DO NOT obstruct the flow of combustion and ventilation air. Burner tubes can become blocked by
spiders and other insects building their nests. Blocked burner tubes can prevent gas flow to the burners
and could result in a burner tube fire or fire beneath the grill. To clean the Burner Assembly follow these
instructions to clean and/or replace parts of burner assembly or if you have trouble igniting the grill.
1. Turn gas off at control knobs and LP cylinder tank valve.
2. Remove cooking grills and heat distribution plates.
3. Remove screws from each burner "foot" using a screwdriver.
4. Carefully lift each burner up and away from valve openings.
5. Use a narrow bottle brush or a stiff wire bent into a small
hook to run through each burner tube and flame port several
times.
Note: Wear eye protection when performing procedure 6.
6. Use compressed air to blow into burner tube and out the
flame ports. Check each port to make sure air comes out
each hole.
7. Wire brush entire outer surface of burner to remove food
residue and dirt.
8. Check burner for damage, if any large cracks or holes are
found replace burner.
IMPORTANT: Burner opening must slide over
valve nozzle.
9. Carefully replace burners.
10. Replace screws on each burner and follow the
"Gas Leak Testing" section of this manual.
Relight burners to verify proper operation.
11. Replace heat distribution plates and cooking grills.

PROPER BURNER OPERATION
Debris
CLEANING AND MAINTENANCE:
• Keep the appliance free and clear of combustible materials, gasoline and other flammable vapors
and liquids.
• Keep the ventilation openings of the cylinder enclosure free and clear of debris.
• Visually check burner flames for proper operation (see pictorial in "Burner Assembly/Maintenance"
under Proper Care and Maintenance). Spiders or other insects can nest in the burner causing gas
blockage.
• For safe grilling and peak performance of your grill, perform these checks at least twice per year or
after extended periods of storage.
• Be sure to tighten up all hardware (nuts, bolts, screws, etc.) at least twice per year.
CAUTION: Some parts may contain sharp edges. Wear protective gloves if necessary.
• Remove the cooking grills, heat distribution plates, and burners from inside your grill. Use a brush with
hot water and detergent to remove excess residue. NEVER use a commercial oven cleaner. Rinse
completely with water. Towel dry and replace all components as described in the assembly instructions.
