To whom it may concern,

HVAC Services has installed 6 new fire dampers type A model 150 as cut sheet describes. Dampers were install plumb inside of duct in wall cavity. Dampers were screwed into place and tested for proper operation. 1 access door was install at each location for inspection and service if fusable link fails. Installation of these fire dampers meets the requirements for a 2 hour rating.
Please see attached submittals on dampers.

Thank You,
