CREOSOTE – FORMATION &
NEED FOR REMOVAL
1. 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 cool
chimney flue of a slow- burning
fire. As a result, creosote residue
accumulates on the flue lining.
When ignited this makes an
extremely hot fire.
2. To prevent creosote build-up:
• Always burn dry wood. This
allows clean burns and
higher chimney temperatures,
therefore less creosote deposit
• Leave the air control fully open
for about 5 minutes every time
you reload the oven to bring
it back to proper operating
temperatures. The secondary
combustion can only take place
if the firebox is hot enough
• Always check for creosote
deposit once every two months
and have your chimney cleaned
at least once a year
3. The chimney connector and
chimney should be inspected
at minimum every two months
to determine if a creosote
buildup of 3 mm (0.1") or more
has occurred. If creosote has
accumulated it should be
18
removed to reduce the risk of a
chimney fire.
The sides of the oven will also
need to be inspected and
potentially cleaned every two
months. To achieve this the
cooktop hotplates need to be
removed so that the sides of the
oven can be scraped. The bottom
plate of the oven will then need to
be removed in order to collect the
loose creosote.
Inspection & Cleaning
1. It is important to establish a
routine for the fuel, wood burner
and firing technique. Check
daily for creosote buildup. Be
aware that the hotter the fire
the less creosote is deposited,
and weekly cleaning may be
necessary in mild weather even
though monthly cleaning may be
enough in the coldest months.
Contact your local municipal
or provincial fire authority for
information on how to handle
a chimney fire. Have a clearly
understood plan to handle a
chimney fire.
2. Apart from removing creosote
buildup within the oven, the only
other maintenance required for
the Nectre Wood-Fired Oven is
to ensure that the door assembly
components are well maintained.
