The venting system of this boiler is under positive pressure. Leakage
from this system can be hazardous and if not avoided can result in
death or serious injury. In addition to the recommendations within this
manual and the User's Information Manual, the venting system, from
the flue collector to the outdoor discharge, must be carefully checked
annually by a qualified service agency.
