    Default Turning down furnace burners?

    Hi All.

    I have a Carrier furnace, 1985, model #58SSB080-BC. It appears to have an electronic ignition.

    I feel like the outlet pressure is too high. It makes quite a roar when it comes on and my heating bills are $200 per month. I feel like there is a lot of waste heat going up the flue which is not captured by the heat exchanger.

    My question is can the gas pressure be turned down?

    The furnace has a valve which allows the inlet and outlet pressure to be adjusted. It has min and max pressures printed on the label. It also has a high and low setting of some sort.

    Or, would the burner orifices need to be changed?

    A furnace that old is probably only about 80% efficient, I would suggest you consider updating to a higher efficiency furnace. The high volume going up the chimney is necessary to get proper draft in a chimney. I doubt you will gain much by trying to make the adjustments you suggest.
