Installation and Operation Manual - Osburn 3500
4.1 The Use of a Fire Screen
This stove has been tested for use with an open door in conjunction with a fire screen, sold
separately. The fire screen must be properly secured on the stove to avoid any risk of sparks
damaging the flooring. When the fire screen is in use, do not leave the stove unattended to
respond promptly in the event of smoke spillage into the room. Potential causes of smoke
spillage are described in Section «8. The Venting System» of this manual. See «Appendix 4:
Optional Fire Screen Installation» for installation instructions.
Operating the stove with a fire screen increases possibilities of generating carbon monoxide. Carbon
monoxide is an odourless gas that is highly toxic which can cause death at high concentration in
air. Installation of a carbon monoxide detector is highly recommended.
4.2 Using a BlowerUsing a Blower
A blower is included with this stove. The blower is already
installed at the back of the stove, the power cord can be
found in the user manual bag. The blower is used to increase
the airflow through the heat exchanger and improve hot air
circulation in the room.
When used regularly, the blower can provide a small increase
in efficiency, up to 2%. However, the use of a blower should
not be used as a way to gain more output from a stove that
is undersized for the space it is intended to heat.
Ensure the blower cord is not in contact
with any surface of the wood fire to prevent
electrical shock or fire damage. Do not run
cord beneath the wood fire.
Figure 8: Air flow with a blower
The blower has a variable speed control that can be adjusted
in three different positions; either from high (HI) to low (LO) or
closed (OFF). Allow the stove to reach operating temperature
(approximately one hour) before turning on the blower, since
increased airflow from the blower will remove heat and affect
the start up combustion efficiency.
The blower can also be equipped with a heat sensor (themodisc),
sold seperatly. When the blower is on (position between HI and
LO), the heat sensor will make the blower start automatically
when the stove is hot enough and will stop it when the stove
has cooled down. Therefore, the blower speed control can
be left at the desired setting. The thermodisc part number is
AC02056 for a quick connect model. See «Appendix 2: Blower
and Optional Thermodisc Installation».
