John Dirks Jr Posted October 29, 2011 Report Share Posted October 29, 2011 I'm tuning up my old Mueller gas furnace circa 1962. I got the burners all cleaned and blown free of debris. Once I get it back together I plan to adjust A/F ratio. I know this is done by rotating the discs on the ends of the burners. What kind of flame characteristics am I looking to achieve?

kurt Posted October 29, 2011 Report Share Posted October 29, 2011 Like a waste of about 50% of the BTU's you're burning. When I ditched my old Climatrol for a Cat I, my gas bill went down about $50 a month. Also, I've never seen a Climatrol that didn't have a crack along the top/back of the exchanger.

I agree we're over due for a new system. Over due for a roof too. Quote Link to comment Share on other sites More sharing options...
Marc Posted October 29, 2011 Report Share Posted October 29, 2011 The yellow is incompletely oxidized natural gas going out the flue, taking with it some of the heat that was produced by the gas that did manage to get oxidized. Don't some folk use wood burning stoves up there? I've a ton or two of oak from a tree I took down last year. Looking to buy one to augment my electric strip heater.

Brandon Whitmore Posted November 15, 2011 Report Share Posted November 15, 2011 John, If you want to find out if your furnace is over or under- fired, let me know. We've been covering this stuff in class, and it's pretty easy to figure out....... Also, those discs you are adjusting are the primary air shutters, at least that's what we've been told to call them.
