Came across a johnson starley reno 30 today where the combustion ratio was ,0008 so thought i would bring the ratio down but could not locate the throttle on gas valve . Read the MI's and said ,0008 is acceptable and i know that anyway but thought i would tweek it . But how do you bring the ratio down on these boilers ?? From what i can see and read in MI's it mentions nothing of how to reduce the ratio .
