CHECKING FOR LEAKS

All points of connection to the gas supply should be
checked for leaks at time of installation or anytime

adjustment is required, loosen the screw on the air
shutter and close or open shutter as required to
achieve proper flame characteristics. Tighten the
screw after adjustment.
All burners should exhibit flames which are blue and
stable, with no yellow-tipping, lifting or excessive
noise when operating on either natural or LP gases.
See Figure 8 for pictorial representation of proper
flame characteristics.
The infrared rotis burner, smoker burner and surface
