Do you always do a inlet and outlet pressure test during a maintenance or just if the flame pattern does not look right ? What if you don’t have a pressure regulator on the inlet side of the gas valve ? Thanks for sharing.

No I don't always check gas pressures. I'll usually check if the flame sounds weak or aggressive or if my temp rise is off. Also you still want to check the inlet pressure whether there's are regulator or not.

when do you usually check the gas pressure? what would make you use these tools to adjust the pressure

Where can I get a manifold just like that one ? The 3rd burner and the end of the manifold is letting out too much of a flame and it’s burning the inside of my furnace. Any suggestions !?

Hey usually I'm all for DIY repairs its one of the reasons I started this channel but Honestly if you don't have the proper equipment to test a combustion Appliance IE combustion analyzer menometers temp probes Id probably just try to call out someone who does as you don't want to be doing experimental repairs on something that literally contains a active fire inside of your house.

If you have a high inlet gas pressure and the out is at the rated 3.5" w.c., can this cause incomplete combustion?

If the inlet pressure is high enough to defeat the gas valve regulator and affect the manifold pressure then yes

Hi, I have a lennox mid efficiency single stage gas furnace. The manifold on rating plate is 3.5"wc. But I am only getting 1.7"wc. I adjusted to 3.5"wc according to the rating plate. But the furnace overheats and my temperature rise is out of specification. The furnace also intermittently short cycles. Can this be a bad gas valve? Thank you.

What type of manometer are you using? If it's digital did you zero it out before checking? Did you check with another instrument? Also what caused you to check the gas pressure in the first place?

Why does this system have a preliminary external regulator? Thanks!

Because the inlet gas pressure is too high of a pressure for the gas valve to meter properly so it needs to be stepped down around 7 to 10 in of water column before the gas valve steps it down to 3.5 in.
