– Factory Built Fireplace installation
The fireplace must not be altered, except for the exceptions listed below. A permanent metal warning label
must be attached to the back of the fireplace, stating that the fireplace may have been altered to
accommodate the insert, and must be returned to original condition for use as a conventional fireplace. The
following modifications are permissible: removal of damper, removal of smoke shelf or baffle, removal of
ember catches, removal of fire grates, removal of viewing screen/curtain, and removal of 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 (2100 F) 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 the damper area
with high temperature sealant.
The Kuma model Aspen is certified for installation into a properly installed factory built fireplace in the
U.S. A Safety listed 6” fireplace liner must be installed and directly connected to the appliance and must
extend to the original factory built chimney cap
Prior to installation:
1.
The following items may be removed in order to facilitate the liner installation: Smoke
Shelf/Baffle, Wood Grate, Viewing Screen, Damper, and ember catches.
2.
The Fireplace itself must not be altered (with the exception of damper removal). Any non-
functioning trims that are removed must be kept so that the fireplace can be restored to full
working order if the insert is ever removed.
3.
The local building department has the final authority to approve, with a permit, the installation of
this appliance into a factory built fireplace. DO NOT INSTALL WITHOUT A PERMIT.
4.
Check for any gap existing between the masonry fireplace construction and the fascia masonry. If
there is a gap, seal with a high temperature masonry mortar.
5.
The installation of the fireplace liner must in no way limit the airflow of the factory built chimney.
6.
The original factory built chimney cap must be reinstalled after the installation of the liner.
Notes on manufactured homes and fireplaces:
1. If you are installing the Aspen into a manufactured home, the fireplace must be manufactured
home approved with outside air capabilities.
2.
The outside combustion air that is fueling the fireplace must be supplied to the air intake on the
back of the Aspen stove. Where the outside combustion air enters the fireplace will most likely
vary depending on the particular fireplace. You will need to make sure that the air entering the
fireplace will not be blocked by setting the unit into place.
3.
All of the above guidelines in this section must be followed.
Guidelines for installation:
Use only pre-fabricated, listed components. Use of field fabricated components and/or using
“makeshift” compromises could result in a house fire.
1.
Secure the damper in the open position.
2.
This fireplace insert must be installed with a continuous chimney liner of 6” extending from the
fireplace insert to the top of the chimney. The chimney liner must conform to the class 3
