#OSO-29 #OSO-34 R.1 November 2020 Hussong Mfg. Co., Inc. • Kozy Heat Fireplaces IMPORTANT INSTRUCTIONS 7
When using electrical appliances, basic precautions should always
be followed to reduce the risk of re, electric shock, and injury to
persons, including the following:
1. Read all instructions before installing or using the heater.
2. This heater is hot when in use. To avoid burns, do not let bare
skin touch hot surfaces. Keep combustible materials, such as
furniture, pillows, bedding, papers, clothes, etc. and curtains at
least 36” (914mm) from the front of the heater.
3. Extreme caution is necessary when any heater used by or near
children or invalids and whenever the heater is left operating
and unattended.
4. Do not operate any heater after it malfunctions. Disconnect
power at service panel and have heater inspected by a reputable
electrician before reusing.
5. Do not use outdoors.
6. To disconnect the heater, turn the controls to OFF, and turn o
the power to the heater circuit at the main disconnect panel.
7. Do not insert or allow foreign objects to enter any ventilation
or exhaust opening, as this may cause an electric shock, re, or
damage to the heater.
8. To prevent a possible re, do not block air intakes or exhaust in
any manner.
9. A heater has hot and arcing or sparking parts inside. Do not use
in areas where gasoline, paint, ammable vapors, or liquids are
used or stored.
10. Use this heater only as described in this manual. Any other use
not recommended by Hussong Mfg. Co., Inc. may cause re,
electric shock, or injury to persons.
11. ALWAYS plug the heater directly into a wall outlet/receptacle.
NEVER use with an extension cord or relocation power tap
(outlet/power strip).
12. AVOID FIRE! Inspect all air vents to make sure they are free from
dust, lint, or other blockage before use. Unplug the appliance
and clean with a vacuum ONLY. DO NOT rinse or allow the
appliance to become wet.
13. This heater is not intended to be a primary heat source. It is for
supplemental heat only.
14. ALWAYS disconnect this heater from the power supply before
performing any assembly and cleaning.
15. NEVER plug this heater into an outlet that is old, cracked, or has
any loose wires or connections. Plugging this heater into a faulty

It is recommended to permanently close the damper in the existing
replace to prevent a cold down draft.
An optional shroud may be purchased from your local dealer for
insert mount installations. Contact your local dealer for details.
If installing for built-in applications,
An optional nishing trim kit is available. The OS29-FTK/OS34-FTK
provides a 3/4” (19mm) nished edge (black metal) to allow a 1/2”
(12mm) nish board and tile or stone to nish up against, creating a
shadow box for the front trim.
Optional hanging side brackets (OS29-CHB/OS34-CHB) are available
for installing Chaska screen fronts with the standard front trim.
The appliance can also be hardwired or plugged into a receptacle
(power cord supplied).
