LIGHTWEIGHT BLOCK-IN INSTALLATION (Cont.)
Feed the flexible duct out of the fireplace and through the block-in construction. The
illustration below shows the duct coming out of the side of the block-in construction. Then
feed the two electrical conduits through the opening in the side. Do not run the electrical
conduits over the top of the fireplace if the blower is placed on the left side of the fireplace.
Feed the conduits underneath or around the back of the fireplace for this application.
