You will lose a bit of efficiency when you switch to natural gas. Natural Gas does not burn at the same efficiency as No. 4 oil. For example typical No. 2 oil efficiency for 3% excess O2 is about 85% where NG would be 82%. The amount of radiant heat emmitted with also decrease. This will decrease heat absorbtion in the furnace and will result in higher furnace exit gas temps into the convection passes. I have seen superheaters damaged after a conversion to natural gas when this was not taken into account. Lastly there will be more moisture in the flue gas formed by the combustion of the gas. If you were burning an oil with a significant sulfur content you may run into backend corrosion issues. This can be avoided with a thorough cleaning of the backend. I recommend you contact the boiler manufacturer before you do this as a little money spent now could potentially save you a bundle.
