1)Remove the screw from the vent hole cover (vent cover 'A') on top of the unit.

2)Take the connector collar and press and rotate it into the hole to cut through the insulation layer. Remove the collar and remove insulation from the collar. The screws for the inner cover should be exposed.

3)Remove the screws from the inner cover (vent cover 'B') and slide it back under the insulation.

4)Extend flex vent and pull the insulation sleeves over the 8” (203mm) diameter fl ex vents. Leave a short section of fl ex vent exposed at each end. On one end insert the collar into the fl ex vent and use a clamp to hold the fl ex vent in place.

5)Use tin snips to cut slits into the rim of the connector collar. A minimum of four tabs will be required so cut the slits 1” (25mm) (i.e. 1” (25mm) wide tabs) apart around the perimeter of the collar.

6)Install the connecting collar into the top of the unit until the bead of the collar rests against the top of the inner top of the unit. Reach inside the upper louver opening and use pliers to bend the tabs (minimum 4) out on the connector collar. A hammer may be required to lightly tap the tabs and bend them so that they fi t tightly against the bottom of the inner top. Pull the insulation sleeve down to the top of the unit. Repeat steps 1-6 for the second fl ex vent and collar assembly.

8)Insert the connecting collar into the other end of the 5 ft. (1.5m) fl ex vent and use an adjustable clamp to hold the vent in place. Cut tabs into the rim of the connector collar (a minimum of 4 tabs will be required). Push the collar through the 8” (203mm) hole in the mounting frame. Use pliers to bend out tabs (minimum 4) to secure the collar to the mounting frame.

9)Pull the insulation sleeve up the flex vent to the back of the mounting frame. The fl ex vent should now be connected to both the unit and the mounting frames securely. Repeat steps 1-8 for the second flex vent assembly.

10)Install the block-off plate to the unit. The block-off plate will cover the upper louver opening of the unit and force the fan air to circulate through the two 8” (203mm) diameter fl ex vents. Put high temperature sealant onto the block-off plate. Mount the block-off plate onto the front of the unit and cover the upper louver opening. Make sure that all exposed holes in the block-off plate are sealed with high temperature sealant

NOTE: Make sure the block-off plate is flush and fastened tightly to the Regency R90 Fireplace.
