Straight Insert Adaptor
The insert adaptor is the heart of the HomeSaver Insert Adaptor System. There are two styles, straight and offset.
This straight insert adaptor is a 5" X 15", 24-ga., 304-alloy stainless steel box that's 8" high and completely open at the top.
The bottom of the box has a 3 1/4" X 13 3/4" opening with a 1/2" lip extending down from the opening.
Flat gasket material comes cemented to the bottom of the adaptor to form a seal. The straight insert adaptor is placed into the rectangular opening on the top of your fireplace insert. Metal tabs on the adaptor bend out to hold it in place.
Then, any of the three insert adaptor transition pieces or 45° insert adaptor elbow simply slide right into the top of the insert adaptor.
The transition piece you choose is not fastened in place in the insert adaptor. It should be allowed to "slip" freely by at least 2". This gives you even more flexibility during your installation. And if you don't need an insert adaptor that's the full 8" high, just trim it down with your sheet metal shears. If you encounter an insert whose exhaust vent doesn't mate to the 3 1/4" X 13 3/4" opening on either the straight or offset insert adaptor, use the insert adaptor boot to get the job done.
