Oil furnace draft question??
I have a Tempstar NOMF105D12 furnace. The furnace is setup up to fire at the middle of the three firing rates. 74k output capacity. The flue draft spec in the manual is -0.06 to -0.025" wc. The overfire pressure draft is speced at +0.01 to 0.025" wc. This ranges my draft regulator damper door to be fully open to fully closed. Should I shoot for the middle of the road after doing an initial air shutter adjust.
