HeatPack Furnace Installation and Operation Manual
46
When you burn in cycles, you rarely need to open the furnace’s loading door while the
wood is burning. This is an advantage because smoke could escape from the furnace
when the door is opened as a full fire is burning. This is especially true if the chimney
connector has 90 degree elbows and if the chimney runs up the outside wall of the house.
IF YOU MUST OPEN THE DOOR WHILE THE FUEL IS FLAMING, OPEN THE AIR
CONTROL FULLY FOR A FEW MINUTES, THEN UNLATCH AND OPEN THE DOOR
SLOWLY.
IMPORTANT
WHEN RELOADING, MAKE SURE YOU KEEP THE AIR INLETS LOCATED AT THE
BOTTOM OF THE DOOR INSIDE THE COMBUSTION CHAMBER FREE OF ASH
OPENING PROCEDURE FOR THE LOADING DOOR
TO MINIMISE THE RISK OF SMOKE SPILLAGE, CRACK THE DOOR OPEN ABOUT
AN INCH (25 MM) AND WAIT ABOUT 10 SECONDS BEFORE OPENING IT WIDE TO
ALLOW STABILISATION OF THE PRESSURE INSIDE THE FURNACE.
10.3.2 Raking charcoal
Rekindle the fire when you notice that the room temperature has fallen. Do not operate
your furnace at too low a setting. Keep the air inlet opened long enough during the fire
start-up to prevent the fire from smouldering, which could stain the glass. You will find
most of the remaining charcoal at the back of the firebox, furthest from the door. Rake
these coals towards the door before loading. There are two reasons for this raking of the
coals. First, it concentrates them near where most of the combustion air enters the firebox
and where they can ignite the new load quickly, and second, the charcoal will not be
smothered by the new load of wood.
If you were to simply spread the charcoal out, the new load will smoulder for a long time
before igniting.
Remove ash first, and then rake charcoal towards the front of the firebox before loading so
that it will ignite the new load.
