1. An outside air inlet must be provided for combustion and
must remain clear of leaves, debris, ice and/or snow. It
must be unrestricted while unit is in use to prevent room
air starvation which can cause smoke spillage and an
inability to maintain a fire. Smoke spillage can also set
off smoke alarms.
2. Unit must be secured to the mobile home structure at
two attachment points. Remove bolts from each side of
insert and use plumbers tape to secure to structure (a
washer may be required). Re-install bolts.

wire or equivalent and terminated at each end with
N.E.C. approved grounding device.

the fireplace fire chamber and the chimney must be
listed to
UL103 HT
or a listed

equipped with a spark arrestor cap and the outside air
must be installed on the insert.
5. Refer to
pages 8-10
of this manual for clearance to
combustibles and floor protections requirements. All
clearances must be followed precisely.
6. Use silicone to create an effective vapor barrier at
the location were the chimney or other component
penetrates to the exterior of the structure.
7. Follow the chimney and chimney connector
manufacturer’s instructions when installing the flue
system for use in a mobile home.
8. Burn wood only. Other types of fuels may generate
poisonous gases (e.g., carbon monoxide).
