WARNING
Apply supplied silicon dielectric grease from attached pouch to gasket inside vent section of two-pipe vent
connector. Failure to apply the grease could result in gasket rupture during vent pipe installation and gasket
deterioration due to condensate exposure.
Check if ue exit gasket inside heat exchanger has factory applied silicon grease. If the gasket lubricant
is missing, apply supplied silicon dielectric grease prior to two-pipe vent connector insertion into heat
exchanger ue exit.
