The Gas Valve in the 80 thru 210 is at the front of the
unit and can be reached after the front panel is pulled

Always be patient with your combustion analyzer when
making adjustments to the valve at both Hi-Fire and
Low-Fire.
Be sure to put the cap back onto the valve when you are
done making your adjustments at the gas valve.
