2. Assemble two cap screw/washer combinations,
then, insert cap screws/washers through a flue outlet
damper assembly-mounting ring at 3 o’clock and
9 o’clock positions. Place the flue outlet damper
gasket onto cap screws and position damper with
gasket onto boiler rear flue collector, aligning screws
with flue collector threaded holes.
3. Thread the screws at 3 o’clock and 9 o’clock
positions into flue collector threaded holes hand
tight.
4. Assemble remaining cap screw/washer
combinations, then, insert cap screws/washers
through a flue outlet damper assembly-mounting
ring/gasket and thread the screws into flue collector
threaded holes hand tight.
5. Alternately tighten the screws with an open end or
socket head wrench to complete the assembly.
