Customer Question
Hello, I have a Bryant 355MAV...
Hello,
I have a Bryant 355MAV 355MAV060080. It is running on LP. I was hoping to check the pressure and adjust if needed. But there is no information on the furnace for the high and low pressures when running on LP. The tag just has the high and low pressures listed for NG. Do you happen to know what the pressures for LP should be?Thanks.

Hello,
Sounds good.
Thanks.
HVAC Technician: airheatman, HVAC Technician replied 8 months ago

Well that took a while looking through several manuals but finally found it.

Depending on your altitude. high pressure at manifold should be 11" on high and 4.9 to 5.4 on low. See below.
