ZERO CLEARANCE (METAL) FIREPLACE INSTALLATION
Your new wood burning insert is approved for use in suitable zero clearance (metal) fireplaces. Make
sure to follow all of the steps listed below to insure proper installation. The installation technique below
illustrates one way of installing your insert. Check with your dealer or installer for information on other
installation options available to you.
1. Inspect the chimney and make sure it follows all the rules outlined in the section titled "CHIMNEY
INFORMATION & REGULATIONS".
2. Follow all of the regulations and guidelines specified in the sections titled "ZERO CLEARANCE
(METAL) FIREPLACE INSERT - SPECIFICATIONS" and "PREPARATION FOR INSTALLATION -
ZERO CLEARANCE (METAL) FIREPLACE INSERT ". Make sure that your brand of zero clearance
(metal) firepalce matches one that is listed. Check with your dealer or installer if there are any
discrepencies.
3. The next step in installing a zero clearance insert is to remove all of the unnecessary components on
your brand of fireplace. Because of the wide differences between fireplace brands and models, it
would be difficult to list all the variations. Below, we have provided a generic view of a typical zero
clearance fireplace to illustrate which parts may or may not be removed.
Parts that may be removed:
1. Damper plate (Must be removed)
2. Smoke shelf
3. All internal baffles
4. Grates (Must be removed)
5. Metal Screen
6. Glass Screen or Doors
Parts that may not be
removed:
¥ Masonry lining or firebricks
¥ Any insulating materials.
¥ Any structured rigid frame
members (metal sides, floor, door
frame, face of fireplace, etc.)

NOTE: The installation of the decorative panels and trim is optional and not required. An alternative to
using the decorative panels is to simply draw the fireplace screens closed around the insert.
4. THE ZERO CLEARANCE FIREPLACE MUST BE INSTALLED WITH A STAINLESS STEEL STARTER
PIPE THAT PENETRATES BEYOND THE SMOKE SHELF AND IS DIRECTLY CONNECTED TO THE
FIREPLACE CHIMNEY. You may want to construct a steel block off plate and install it or use a pipe
adaptor to fill the gap between the fireplace chimney and the 6" stainless steel starter pipe that you
will be installing. See the illustration of a block-off plate example on the next page for what a block-off
plate should look like in a zero clearance (metal) fireplace.
5. Allow a minimum of 1" on each side of the plate larger than the outside dimension of the chimney flue
diameter. The 1" overlap of the block off plate is required to properly seal the gap between the
chimney and the 6-1/4" hole in the block off plate.
