BURNER ADJUSTMENT– VGSB5152
Each burner is tested and adjusted at the factory prior to shipment; however, variations in the local gas supply may make it
necessary to adjust the burners. The flames of the burners should be visually checked and compared with flame height
illustration.
Flames should be blue and stable with no yellow tips, excessive noise or lifting. If any of these conditions exist, check if the air
shutter or burner ports are blocked by dirt, debris, spider webs, etc. With a proper flame height, adjust the air shutter to
obtain a blue flame with no yellow tipping that sits on the burner at the burner ports. The air shutter is locked in place by a set
screw which must be loosened prior to lighting the burner for adjustments.
To access the air shutter on the side burners, remove the grates, burner bowls, and grate support. With a screw driver, loosen
the lock-screw on the face of the air shutter. Light the burner and adjust according to the directions below.
1. If the flame is yellow, turn the air shutter counter clockwise to allow more air to the burner.
2. If the flame is noisy and lifting away from the burner, turn the air shutter clockwise to reduce the amount of air to
the burner.
Once adjusted, turn the burner off, tighten the set screw on the air shutter, replace the valve panel for the side burners and the
grate support, burner bowls, and grates for the side burners.
To ensure proper installation of the side burners, slide opening in air shutters over the orifice located in the front of the unit.
