Operating The Oven; Burning Tips; Flue Draught - Nectre Fireplaces Big Bakers Operating Instructions Manual


Prior to closing the air slide ensure that the fire is
burning briskly. This may require opening the air slide
fully for 10-15mins before shutting down.

For the optimum between clean burning, and getting
the best in efficiency, from the fully closed position,
open the top air slide 4-5mm.
The top air slide can be adjusted to any position so desired
depending on wanted heat output versus burn time.
Reload with more wood:
1. Open air slide before opening door.
2. Rake / break up any existing coals.
3. Load the wood with the length orientated front to back.
4. Better results will be achieved by loading several
smaller pieces of wood rather than one large piece.
5. Close door with top air slide fully open, and leave for
minimum of 10 minutes to allow the fresh wood to
catch.
6. After 10 or more minutes, the top air slide can be
adjusted to the desired heat output setting.

6. OPERATING THE OVEN

When using the oven ensure that the by-pass damper is in
the closed position, and the bottom air slide in the oven door
is closed.
To maintain a constant oven temperature, have the fire
burning briskly using small pieces of wood that provide plenty
of flames.
If the temperature in the oven gets too hot, reduce the
amount of oxygen to the fire by partially closing the top air
slide. Alternatively, open the bottom door slide control in the
oven door.
If the temperature in the oven drops below that desired,
open the top air slide and add some more pieces of wood if
required.
The round hotplates in the top of the heater can be removed
for cooking purposes allowing direct flame to a wok or
frypan. A triangular-handled tool is provided for lifting out
the round hotplates.

7. BURNING TIPS

Fuel Quality
1. Use wood with a moisture content of less than 20%.
Logs should not feel moist or damp, or have moss and
fungal growths.
2. Symptoms related to wet wood:

Difficulty starting and keeping a fire burning well

Smoke and only small flames

Dirty glass and/or fire bricks

Rapid creosote build-up in the flue/chimney

Low heat output

Short burn times, and blue/grey smoke from the
flue/chimney outlet
3. If on the rare occasion the wood is not ideally seasoned,
still retaining some moisture, continue using the top air
slide to determine the heat output and burn rate but
also leave the bottom air slide open 3-4mm. This will
allow some extra oxygen into the base of the fire
allowing it to burn hotter.
4. Run the appliance at high heat output for a short period
each day to avoid large build-up of tars and creosote
within the appliance and flue.

Flue Draught

The flue has two main functions:-
1. To remove smoke, gases and fumes from the appliance.
2. To provide a sufficient amount of draught (suction) in
the appliance to ensure the fire keeps burning.
Draught is caused by the rising hot air in the flue when the
fire has been lit.
The position, height and size of the flue can affect the
performance of the flue draught. Refer to installation guide
for details on flue installation.
Factors affecting the flue draught include:

Insufficient flue height

Trees or other buildings nearby causing turbulence

High and gusty winds

Outside temperature and weather conditions

Blocked flue
For advice on the correction of persistent flue problems
consult your supplier/installer for more detail.
