AirCo furnace with fanlimt , indujcer and ignition control kicks on and goes for approxtimatly 10 min then the venting rollout trips . Replaced the inducer and the venting rollout however the problem still there .
Inducer close the pressure switch and the manometer shows .70" wc out of the inducer .

Old Airco inducer was very noisey first and we had to replace it , now that we have replaced it with a new one , the new inducer with rpm same as the original tripping the venting rollout
The furnace uses fanlimit , inducer and ignition control kicks on and goes for approxtimatly 10 min and the blower kicks on and everything going good then the venting rollout trips all of a sudden . Replaced the inducer and the venting rollout however the problem still there .
Inducer close the pressure switch and the manometer shows .70" wc out of the inducer . Used resitrictor in different ways still the problems there
Any comments will be appreciated

Check discharge/flue pipe that goes outside for restrictions or something in the pipe itself.

Tks for your answer . Well , there is another furnace just next to it with the same specs and working fine . The distance of discharge flue from the inducer to the main chimney is approx 15ft . Am going to check it out though .
