Atwood appliances. All rebuilt within past year. New regulators. New flame sensors. New main regulator. New temp sensors. Etc. Full tanks. Heater and water heater were working last weekend. This weekend the furnace fires but shuts down; tries three times before lock out. Water heater fires but flame just flutters (as with low pressure). Stove works fine. Checked water column at stove (before regulator) and have 13 with open tank, no appliances; drops to 11 when furnace attempts to fire. It seems like the problem is low pressure - possibly due to temperature drop in the past week? And yet, the pressure reading at the lower temperature is correct according to the manuals. Any suggestions? Thank you.
