Service Hints - United States Stove Company Hot Blast HB1520 Owner’s Instruction And Operation Manual

ASH REMOVAL & DISPOSAL
Never let your ashes get any higher than the pilot air hole.
Remove ashes as needed leaving at least 2 inches of ash
in the bottom of the firebox. 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, away from all combustible
materials, pending final disposal. The ashes should be
retained in the closed container until all cinders have
thoroughly cooled.
CAUTIONS:
• ASHES COULD CONTAIN HOT EMBERS EVEN
AFTER TWO DAYS WITHOUT OPERATING THE
STOVE.
• THE ASH PAN CAN BECOME VERY HOT. WEAR
GLOVES TO PREVENT INJURY.
• NEVER BURN THE STOVE WITH THE ASH TRAP
OPEN. THIS WOULD RESULT IN OVER FIRING
THE STOVE. DAMAGE TO THE STOVE AND EVEN
HOUSE FIRE MAY RESULT.
SMOKE & CO MONITORS
Burning wood naturally produces smoke and carbon
monoxide(CO) emissions. CO is a poisonous gas when
exposed to elevated concentrations for extended periods
of time. While the modern combustion systems in
furnaces drastically reduce the amount of CO emitted
out the chimney, exposure to the gases in closed or
confined areas can be dangerous. Make sure you stove
gaskets and chimney joints are in good working order
and sealing properly to ensure unintended exposure. It is
recommended that you use both smoke and CO monitors
in areas having the potential to generate CO.
