ADJUSTMENTS



The control cables are connected at the heater module to the air valve that each cable operates. The cable ends are attached to the air valve crank arm by a self-adjusting clip that grips the cable core firmly. Adjustment can be accomplished by moving the temperature lever briskly back and forth to both extremes of lever travel in the control assembly. When the cable is properly adjusted, the air valve may be heard hitting it's stop at both extremes of travel.
