One Hand And Install 3

Mounting Bolts Finger Tight

8.Hold the ceiling template with one hand and with the other, install the three 1/4" mounting bolts through the template and into the base pan.

a.Finger-tighten the bolts and check alignment. There should be an equal opening on each side and the rear flange must be tight against the roof opening.

b.EVENLY tighten the three bolts to a torque of 40 to 50 inch pounds. This will compress the roof gasket to approximately 1/2". The bolts are self locking so over tightening is not necessary.
