FLASH FIrES

A fl ash fi re is created by igniting a very loosely stacked pile of kindling (typically but not restricted to wood with
EN
a cross section less than 1" X 1" (25mm X 25mm)). A major characteristic of a fl ash fi re is that the wood is piled
in such a way that the volume of the fuel pile can consist of as much if not more air space as there is wood
fuel. The intensity of the fl ash fi re can be greatly increased if supply of combustion air is increased (fi re
box or ash doors left open during fi re). Although small fl ash fi res are a part of developing a charcoal bed when
starting the furnace up from a cold start they can create unsafe operating conditions, damage to the furnace
and void all warranties. Flash fi res may only be used when starting the furnace from a cold start and the fuel
stack should never occupy more than 1/3 of the fi rebox volume. Do not create or maintain fl ash fi res once the
furnace is capable of sustaining operating using regular full size wood in tightly packed bundles. never create
a fl ash fi re during a power out condition, damage to the furnace is likely and all warranties will be void. Typical
symptoms of fl ash fi res which have caused over fi ring include glowing furnace components and melted exterior
paint.

8.10 SmOkING

a properly installed appliance should not smoke. if yours does, check the following:
• Has the chimney had time to get hot?
• is the smoke passage blocked anywhere in the appliance, chimney connector or chimney?
• is the room too airtight and the air intake not connected to the outside? Try with a window partly open.
Is the smoke fl ow impeded by too long a horizontal pipe or too many bends?
•
• is it a weak draft perhaps caused by a leaky chimney, a cold outside chimney, too large a diameter of a
chimney, too short a chimney, or a chimney too close to trees or a higher roof?

A bed of ashes approximately 1" (25mm) deep should be left on the firebox bottom to help maintain a hot charcoal
bed. When the fire has burned down and cooled, remove any excess ashes. To remove the ash, follow the directions
below.
A. after the last coal has extinguished, let the appliance cool at least two hours.
B. open the appliance doors.
C. Move ashes through the grate in the fire box floor, open the ash removal door and slide out the ash pan.
Place the ashes into a steel, container with a tightly fitting lid. Other waste shall not be placed in this con-
tainer. replace the ash pan and ensure the ash removal door is tightly closed. Cover the container with
the lid and move the container away from the appliance onto a suitable non-combustible surface outdoors
where the ashes can safely cool away from any combustibles. dispose of the ashes.
