Larger diameter and irregular shaped logs are more
likely to cause wood to hang up or ‘bridge.’ It is best to
mix larger logs with smaller logs.
3. Load wood into the firebox.
Centre wood in the firebox. There should be a gap of
several inches between the wood and both the front
and back of the firebox. Placing wood up against
the back of the firebox can result in unburned wood
which can cause logs to hang up.
4. For the most efficient burn always keep the brick hot
by maintaining wood in the firebox.
Cleaning out ash
Firebox and secondary Burn Chamber
Ash in the secondary burn chamber should be cleaned
out bi-weekly or as necessary, depending on fuel quality
and burn rate. Clean ash out of the secondary burn
chamber first. Then clean the firebox. Otherwise hot
wood coals will be scraped out of the secondary burn
chamber along with the ash.
To clean ash out of the firebox, gently rake it into the
secondary burn chamber through the opening in the
bottom of the firebox. It is important to rake ash buildup
away from the back wall of the firebox.
1. Do this when fire has died down before reloading
furnace. Switch blower off.
2. Open ash clean out door.
3. Pull out ash tray.
4. Reach the ash rake to the back of the chamber and
pull ash forward into the ash tray.
5. Firmly close and latch ash clean out door.
6. Switch blower on.
Flues and Chimney
Switch furnace off.
For highest efficiency clean the heat exchanger flues
several times a season.
1. Clean ash from secondary burn chamber before
cleaning flues.
2. Remove rear access cover and flue clean out cover
(see page 8). Ensure ash door is closed.
3. Assemble flex rods and attach to the brush and
push brush completely through flues. Should the
brush be too difficult to p
ush through, then first
push the rod through without the brush.
4. Inspect and clean any buildup in the exhaust area.
5. Replace covers. Secure rear access cover with screws.
6. Open ash clean out door and ensure the ash is
cleared from the flues.
Switch furnace on.
disposal of ash
Ashes should be placed in a metal container with a tight
fitting lid. The closed container of ashes should be placed
on a noncombustible floor or on the ground, well away
from all combustible materials, pending final disposal. If
the ashes are disposed of by burial in soil or otherwise
locally dispersed, they should be retained in the closed
container until all cinders have thoroughly cooled.
Creosote - Formation and need for removal
When wood is burned slowly, it produces tar and other
organic vapors, which combine with expelled moisture
to form creosote. The creosote vapours condense on
the relatively cool firebox walls of a slow burning fire. As
a result, creosote residue accumulates on the firebox
walls. When ignited this creosote makes an extremely
hot fire. To reduce the amount of creosote, a small
intense fire is preferrable to a large smoldering one.
Fire Brick and insulation
The secondary burn chamber of the Pristine high efficiency
furnace is lined with high temperature insulation. It is
designed to sustain high furnace temperatures and regular
operation for many years. The floor of the firebox is lined
with brick. To see signs of wear and cracking of the brick is
normal.
Take the following precautions to protect the fire brick and
maintain optimal performance.
1. Do not carelessly throw heavy pieces of wood onto the
brick.
2. Gently rake ashes out of secondary burn chamber.
3. Do not damage brick while stirring the fire.
4. Do not attempt to cool down hot bricks quickly.
5. Do not run furnace with pieces of brick missing.
6. Do not alter the brick and insulation layout. This layout
has been carefully engineered to achieve the best
performance.
