h) Where the wall liner meets the back of the PRV, seal gap with a bead of intumescent fire-rated

caulk.

i) Check that each and every blade of the PRV opens freely. If blades are rubbing against the side

casing check to make sure the frame of the PRV has been fitted square and is not twisted and

there is no part of the wall opening that is jamming on the vent casing. (it may be possible to

free slightly rubbing blades by tapping out casing where they touch, with a hammer).
