Hi all,
I had a technician today checking my furnace (label attached) due to restarts. First thing he checked was the temp raise and indeed it was too high (~80F) so he reduced the gas pressure by turning some knob inside the furnace counter-clockwise with a flat screwdriver. Doing so also reduced the noise and made the flames smaller. It seems like now the temp raise is in range but then after he left I tried to educate myself a bit about what was done and watched some youtube videos and in all of them the techs use manometers to make sure that the gas pressure is in range and not just dial it down that the temp raise will be in range.
My main concern right now, are there any risks associated with furnace running with too low gas pressure that outside manufacturer range?
