4. For the most efficient burn always keep the brick
hot by maintaining wood in the firebox.
5. DO NOT cover the brick slots when placing wood
into the firebox.
daily routine
morning loading:
Load wood into the unit as described above.
late afternoon Check:
Check the unit to ensure there is sufficient wood to burn
until the end of the day. Load just enough fuel to ensure
a bed of burning charcoal is in the firebox prior to the
night loading.
Note: The firebox is hottest when the wood has burnt
down to a bed of charcoal. When the primary chamber
has burnt down to this level, the firebox will dry out
and burn most of the accumulated creosote on the
walls. If the primary chamber is full all of the time, the
temperature in the firebox stays quite cool and creosote
may build up on the walls.
night loading:
Rake the coal and ash from the perimeter of the firebox
and especially from the back wall of the chamber where
ash tends to build up. With the ask rake, pull the ash
and charcoal away from the walls. The force of the fan
will blow the ash into the lower chamber on its own. If
this is done every day the ash should fall through the
slots easily.
Load wood into the unit as described above.
Cleaning Out ash
Firebox and secondary Burn Chamber
Ash in the secondary burn chamber should be cleaned
out 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 the 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. Do not scrape all
of the ash into the ash tray. It is recommended to
leave 1”-2” (2.5 - 5.1 cm) of ash covering the floor of
the firebox.
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
weekly or as necessary.
1. Clean ash from secondary burn chamber before
cleaning flues.
2. Remove flue clean out cover (see page 9).
3. Push brush completely through flues. Should the
brush be too difficult to push through, then first push
the rod through and pull from the other end.
4. Inspect and clean any buildup in the exhaust area.
5. Install clean out covers and secure rear access door
latch with bolt and tighten with wrench.
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 Empyre Elite XT 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.
