Don't have a lot of time look in this Service Manual maybe it there...

Lennox has a new policy...if it's out of warranty...replacew it!
pressurize to 4psi if any pressure after 10 minutes it passes. have not seen a bad one yet that would hold pressure more than about 30 seconds. any small leaks are found on test plugs or spark plug,flame sensor
