Lennox Hearth C210 - Manual (Page 11)

Fireplace and Chimney Requirements
This appliance must only be installed in a zero clearance factory-built
fireplace using 6” (152mm) stainless steel pipe extending from the
insert’s flue into the chimney of the fireplace. For optimum safety and
performance we recommend a full length stainless steel liner directly
connected to the insert’s flue outlet.
This appliance must only be installed in a zero clearance factory-built
fireplace that is structurally sound. Fireboxes or chimneys that have flaws,
burnouts, or warping must be replaced or repaired prior to installation.
Check with your fireplace manufacturer if any problems exist.
All convection vents and louvers must be left unmodified and unob-
structed.
This appliance can only be installed in the following brands of factory-
built zero clearance fireplaces: LENNOX, SUPERIOR, HEATILATOR,
MAJESTIC, MARTIN, PREWAY, MARCO, TEMCO and FMI.
The fireplace cavity must be 36” (914 mm) in width, 21” (533 mm) in
height and 14” (356 mm) in depth. Installation in larger size fireboxes
of the same brands is permissible.
Installations into other brands of the same size is permissible only with
approval from local building officials.
Modifications allowed to the factory-built fireplace are as follows:
- Remove the damper
- Remove the smoke shelf or smoke baffle
- Remove ember catches
- Remove viewing screen/curtain
- Remove side and rear bricks
- Remove the fire grate
- Remove doors
The factory built chimney must be listed per UL 127 (US), and meet type
HT requirements of UL 103 (US). Factory built fireplace chimneys tested
to UL 127-1998, may be at the fireplace manufacturer’s option, tested to
the same criteria as UL 103 HT requirements. If the chimney is not listed
as meeting HT requirements, or if the factory built fireplace was tested
prior to 1998, a full height listed chimney liner must be installed from
the appliance flue collar to the chimney top. The liner must meet type
HT requirements (2100ºF) per UL 1777 (US). The liner must be securely
attached to the insert flue collar and the chimney top. To prevent room air
passage to the chimney cavity of the fireplace, seal either the damper area
around the chimney liner with high temperature sealant or the fireplace
front with fiberglass batting.
INSTALLATION PROCEDURE - FACTORY-BUILT ZERO
CLEARANCE FIREPLACES
FIREPLACE PRE-INSTALLATION PREPARATION
NOTE: LENNOX HEARTH PRODUCTS RECOMMENDS PROFES-
SIONAL INSTALLATION BY A LICENSED AND BONDED INSTALLER.
SEE YOUR DEALER FOR RECOMMENDATIONS. IMPROPER
INSTALLATION OR MIS-USE WILL VOID YOUR WARRANTY AND
CREATE A SERIOUS SAFETY HAZARD.
Remove any doors or screen materials from the fireplace opening. Re-
move the damper mechanism completely. Also remove grates or ember
catches inside the fireplace hearth. If your fireplace is equipped with a
smoke shelf or baffle and if it interferes with the installation it may be
removed. Side and rear refractory may also be removed, if necessary,
to facilitate installation. No modifications shall be done unless allowed
on the previous list. Retain all removed parts, they must be reinstalled
before the fireplace can be used in it’s original condition.
CLEARANCE TO COMBUSTIBLES
See “Required Clearances” on Page 7.
Install the two 3” (76 mm) long bolts (with the head up) through the nuts
attached to the insert on the lower rear corner of each side. This will allow
you to level the insert when placed into the fireplace.
Measure from the front of the top surround mount to the center of the
flue. Determine if there is an alignment problem in connecting a liner
from the chimney to the insert’s flue. If there is an alignment problem,
connection can be made using a short piece of stainless flex or a stain-
less steel offset box (available from your dealer). Before installing the
liner, make any attachment brackets or drill any holes in the liner, offset
box, or insert. Once installed, it may be difficult or impossible to drill
additional holes.
INSERT PRE-INSTALLATION PREPARATION

altered to accommodate the insert, and must be returned to original
condition for use as a conventional fireplace. The following modifica-
tions of factory built fireplaces are permissible: removal of damper,
removal of smoke shelf or baffle, removal of ember catches, removal
of fire grate, removal of viewing screen/curtain, and removal of doors.
Note: Secure the tag using screws or nails to the fireplace.
