Page 19 Wood Inserts – Owner’s Manual
ENGLISH
The blower has a variable speed rheostat that can be adjusted
from high (HI) to low (LO) and closed (OFF).
Allow the insert 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 is also equipped with a heat sensor. When the blower
is ON, it will start automatically when the insert is hot enough
and it will stop when the insert has cooled down. Therefore, the
blower speed control can be left at the desired setting.
5.2 Fire Screen
Some inserts have been tested for use with the door open with a rigid firescreen
(In the United States
or in provinces with a particulate emissions limit (e.g.: US EPA), the use of open-door wood
insert with a rigid firescreen is prohibited)
, this option is sold separately (to confirm that your
product has been tested with it, please refer to the Wood Insert Installation and Operation Manual ).
The fire screen must be properly secured on the insert to avoid any risk of sparks damaging the
flooring. When the fire screen is in use, do not leave the insert unattended to respond promptly in the
event of smoke spillage into the room. Potential causes of smoke spillage are described in Section
« 7. The Venting System » of this guide. See « Optional fire screen installation » in the
Wood Insert
Installation and Operation Manual for installation instructions.
OPERATING THE INSERT 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.
5.3 Exhaust System
Wood smoke can condense inside the chimney, forming a inflammable deposit called creosote.
If creosote builds up in the system, it can ignite when a hot fire is burned in the insert. A very
hot fire can progress to the top of the chimney. Severe chimney fires can damage even the best
chimneys. Smouldering, smoky fires can quickly cause a thick layer of creosote to form. When
the insert is operated properly, the exhaust from the chimney is mostly clear and creosote builds
up more slowly.
Creosote - Formation and Need to Removal
When wood is burned slowly, it produces tar and other organic vapors, which combine with
expelled moisture to form creosote. The creosote vapors condense in the relatively cooler chimney
flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When
ignited this creosote makes an extremely hot fire.
The flue lining and chimney should be inspected at least once every two months during the
heating season to determine if a creosote buildup has occurred. If creosote has accumulated (
⅛″
[3mm] or more it should be removed to reduce the risk of a chimney fire»
5.3.1 Cleaning Frequency
It is not possible to predict how much or how quickly creosote will form in the chimney. It is
important, therefore, to check the build-up in the chimney monthly until the rate of creosote
formation is determined. Even if creosote forms slowly in the system, the chimney should be
cleaned and inspected at least once each year.
