BURNER ADJUSTMENTS
As all of American Heating Technologies products, the grills have also been tested in the factory
before shipping. However, due to different gas pressures and heating values of different gas
suppliers, burner flame adjustments might be necessary, especially when converting a unit from
one type of gas to another. This adjustment could be made by reducing or enlarging the air inlets
at the tip of the burners. Please see diagram (A). The goal of adjusting burner flames is to get a
stable blue fire with no yellow tips and no lifting.
PROBLEM
SOLUTION
LOW setting adjustment:
LIFTING:
YELLOW TIPS:
When the amount of air going into the
burner is not enough, or burner ports
are blocked by debris and other particles,
causing the tips of the flame to look yellow
A gap between the burner and the flame
as if the flame is not connected to that
burner
Too much air going through the burner is causing
this. Turn the air shutter dial to reduce air inlet holes
while observing burner flames for changes.
Turn air shutter dial to open air inlet and allow more
air. Make sure all burner ports are clear of dust and
other debris and particles.
Adjust the burner "Low" setting by using a long stemmed flat-head screwdriver, inserting the screwdriver
into the Burner Control Valve stem, and turn the adjustment screw (turn counter clockwise)
producing a stable flame when the Burner Control Valve is set on "low." This applies to all operations.
