Accessories are available for use as wall pass-
throughs. If using one of these, make sure it has been
tested and listed for use as a wall pass-through.
U.S.: In the United States, the National Fire
Protection Association (NFPA) has established
guidelines for passing chimney connectors
through combustible walls. Many building code
inspectors follow these guidelines when approving
installations.
The following illustration shows one NFPA-recom-
mended method. All combustible material in the wall is
cut away a sufficient distance from the single-wall
connector to provide the required 12" (300 mm)
clearance for the connector. Any material used to
close up the opening must be noncombustible.
Three other methods are also approved by the NFPA.
These are:
• Using a section of double-wall chimney with a 9"
(230 mm) clearance to combustibles.
• Placing a chimney connector pipe inside a
ventilated thimble, which is then separated from
combustibles by 6" (150 mm) of fiberglass insulating
material.
• Placing a chimney connector pipe inside a
section of 9" (230 mm) diameter, solid-insulated,
factory-built chimney, with two inches of air space
between the chimney section and combustibles.

Canada: In Canada, the Canadian Standards
Association has established different guidelines.
The illustration below shows one method, in which
all combustible material in the wall is cut away to
provide the required 18" (460 mm) clearance for the
connector. The resulting space must remain
empty. A flush-mounted sheet metal cover may be
used on one side only. If covers must be used on
both sides, each cover must be mounted on
noncombustible spacers at least 1" (25 mm) clear
of the wall. Your local dealer or your local building
inspector can provide details of other approved
methods of passing a chimney connector through a
combustible wall.
In Canada, this type of installation must conform to
CAN/CSA-B365, Installation Code for Solid Fuel
Burning Appliances and Equipment.
NOTE: Do not vent your Resolute Acclaim into a
factory-built (zero-clearance) fireplace under any
circumstances. The Resolute Acclaim has not been
specifically tested and listed for this type of instal-
lation. These appliances and their chimneys are
specifically designed as a unit for use as fireplaces. It
may void the listing or be hazardous to adapt them for
any other use.
DO NOT CONNECT THE RESOLUTE ACCLAIM TO
ANY AIR DISTRIBUTION DUCT OR SYSTEM.
