Your friend doesn't have a furnace company do the annual maintenance on his
furnace. He thinks he's competent to tell you that "no problems" after
adjusting settings?

Please take out a life insurance policy on his family, and put me as the
beneficiary.

my best friend throttled his back last winter, and had no troubles.

wouldnt recommend this for a direct vent 90+ type.

his furnace would occasionally gop boom on start up, throttled back it
didnt but ran longer.

he cleaned the burners this summer they were clogged near pilot light,
no more boom explosions
