5. Fit the wall thimble onto the flex-pipe, prior to the wall thimble installation, and
fasten together using 4 sheet metal screws. Measure from top of fireplace to
planned outlet location and trim the flex-pipe if necessary.
6. Install the wall thimble to the outlet framing using 4 of the supplied wood screws
and run the flex pipe to fireplace.
7. Attach the bottom of the flex-pipe to the duct adaptor on the unit and secure us-
ing 4 of the supplied sheet metal screws. Bring the outside insulation and sleeve
down to the top of the unit, ensuring that the openings in the duct adaptor, (left
by bending the adaptor tabs down) are fully covered (see Figure 23).
INSTALLATION NOTES:
• When framing for the outlet grill: The minimum height from
the bottom of the unit to the center of the outlet is 68” (1.7m)
with the minimum distance from the center of outlet to the
ceiling and for the center of the outlet to a side wall of 11”
(279mm).
• Do not connect the hot air ducts to a central heating system.
• Use only IHP grills and components as described in this
manual.
• Ensure that the flex insulation and sheathing do not touch
the flue pipe.
• Never allow the pipe to pitch downwards. Never route the
piping downwards.
• The hot air outlet grills must be installed with the louvers
pointing downwards.
• The hot air outlets can be installed in the same room as the
fireplace, or one or both of the outlets can be installed in
adjacent or upper rooms. Installing the ducts at different
elevations will tend to exhaust more heat out of the higher
outlet
• When traversing a combustible wall or floor, a firestop (not
provided) must be installed at the wall or floor penetration.
Maintaining a minimum 1” (25mm) clearance between the
ducts and any combustible material, the hole size must be
13” X 13” (330mm X 330mm) (see Figure 24).
• Install to local codes and regulations.
