United States Stove HOTBLAST 1950 Furnace User Manual


 
4.3 HEATING
1. When loading the furnace, spread the coal and embers evenly in the center of the combustion chamber before
adding new logs.
2. Do not overload. Air must circulate freely in the upper part of the combustion chamber in order to obtain an
efficient operation of the appliance. Please note that a small hot fire will produce much less residues than a large
smouldering one.
IMPORTANT: DURING THE HEATING PROCESS, REMOVE THE ASHES AND WOOD THAT COULD
OBSTRUCT THE 1/4" (6.4 mm) HOLE LOCATED BELOW THE DOOR INSIDE THE FURNACE.
PROCEDURE TO OPEN THE LOADING DOOR
TO MINIMIZE THE RISK OF SMOKE SPILLAGE, OPEN THE DOOR 1”
AND WAIT ABOUT 10 SECONDS BEFORE OPENING COMPLETELY.
THE PURPOSE IS TO STABILIZE THE PRESSURE INSIDE THE FURNACE.
4.3.1 EARLY SIGNS OF OVERFIRED FURNACE
1. Roaring fire.
2. Chimney connector is glowing red.
3. Extreme heat coming from the furnace.
4. If this occurs, DO NOT OPEN THE DOOR, shut-off the air inlet opening completely, and wait until the glow has
completely subsided.
ALWAYS KEEP THE DOOR AND THE ASH DRAWER CLOSED
(except for lighting and maintenance).
4.3.2 WOOD AS HEATING FUEL
We recommend that you burn seasoned hardwood only.
There are two important factors to be considered when choosing a type of wood: the moisture content and the
wood density. Dry hardwood, such as maple, oak and beech will provide better results because of the high density
and minimal tar produced during combustion. It is highly recommended to use wood that has been dried at least six
months.
Do not use coal as heating fuel in this appliance.
