Formation Of Creosote; Blower - Jøtul C 350 Installation And Operating Instructions Manual

Jøtul C 350 Winterport 138376_Rev_H 8.2.10
It is also important to remember that chimney
size, temperature and height all affect draft which in
turn affects the formation of creosote. An exterior
chimney, whether masonry or prefabricated steel,
will be exposed to cold outside temperatures, and
consequently, will be more prone to creosote accu-
mulation than an interior flue.
A chimney flue located within the home interior
will benefit from the insulating characteristics of the
building itself. Consequently, the flue system will be
less conducive to condensation of unburned gases
and minimal creosote accumulation will result..
As a general rule, try to avoid burning the insert
at the lowest air control settings. Although a low
setting will prolong burn time, it may also result in
incomplete combustion. In reducing the fire intensi-
ty, draft is weakened and the chimney flue cools. This,
together with the increase in unburned gases, leads
to rapid creosote accumulation.
Blower Operation
Access the blower control panel by lifting the cast
iron lower grille up off the insert.
The dual blowers will enhance heat circulation
around the firebox and out into the room. In the
Automatic setting, the blowers are controlled by a
heat activated switch (snapstat) that will only func-
tion when the speed control is ON. After the fire has
been burning for a time, the snapstat will react to
the heat and activate the blowers. Conversely, the
blower will continue to operate until the snapstat
cools as the fire wanes. The blowers will then shut
off automatically.
The Manual setting overides the snapstat func-
tionality allowing blower operation regardless of
temperatures.
For best performance, do not turn the switch on
until after the fire is well-established.
If the blower is not needed, place the blower
control switch in the OFF position.
