BURNER ADJUSTMENTS:

NOTE: Alfresco grills are available with both U-burners and IR burners. The following instructions apply

only to the U-burners. IR burners do not require adjustment and need only be checked visually for proper

performance. On high, an IR burner should glow red evenly through all its surface.

U-BURNER AIR ADJUSTMENT:

Each grill burner is tested and adjusted at the factory prior to shipment; however, variations in the local

gas supply, elevation and other factors might make it necessary to adjust the burners. The flames of the

burners should be visually checked and compared with Figure 4.

Flames should be blue and stable with no yellow tips, excessive noise or lifting.

If any of these conditions exist, check if dirt, debris, spider webs, etc., are blocking the air shutter or

burner ports. Proceed with air shutter adjustment.

AIR SHUTTER ADJUSTMENT:

A sheet metal cup at the inlet of the burner called the “AIR SHUTTER” regulates the amount of air that

enters into the burner for combustion.

The air shutter is locked in place by a set-screw, which must be loosened prior to lighting the burner for

adjustment. The air shutter adjustment screws are accessible with a flat screwdriver by removing the

burner. Loosen the set-screw of the air shutter. Reinstall the burner. Make certain that the burners are

sitting properly on the orifices taking care not to move or damage the igniter electrode.

Light the burners and adjust according to the following directions:

• Turn the valve on “HI”, light the burner and allow it to “WARM UP” for 10 minutes.

• If the flame is yellow, indicating insufficient air, turn the air shutter counter-clockwise to

allow more air to the burner.

• If the flame is noisy and tends to lift away from the burner, (WITH THE BRIQUETTE

TRAYS IN POSITION) indicating too much air, turn the air shutter clockwise to reduce

the amount of air to the burner.

NOTE: Be careful, as the burner could be and / or will become very hot after lighting it.
