Central Boiler CL 4030 Owner's Manual page 6

IMPORTANT PRECAUTIONARY INFORMATION
The information contained on pages 5-6 appears throughout this manual. Be sure to read carefully and
understand these precautions before, during and after the installation, operation and maintenance
of the outdoor furnace.
WARNING
Maintain the following clearances from
combustibles for the furnace installation:
• 18" from the back
• 6" from the sides
• 48" from the front
• 18" from the chimney inspection cover
• The foundation must be noncombustible
WARNING
For fire safety, keep all combustible materials
at least six feet away from the outdoor furnace,
especially around the door area. Debris of wood
chips and other combustibles in the loading area
may be easily ignited if a hot coal is spilled out of
the firebox and left unnoticed.
WARNING
The firebox door must be closed and latched
at all times except when filling the firebox with
wood. Leaving the firebox door open may lead
to a runaway fire. In the event of a runaway fire,
close the firebox door.
WARNING
All covers must be maintained at all times except
during maintenance, inspection and service.
WARNING
Use only untreated wood in the firebox. Do
not burn garbage, gasoline, rubber, engine oil,
naptha, plastics, treated wood or combustibles
other than wood.

NOTE: Chloride or sulfurous gases can be
generated if plastic or rubber is burned and will
mix with the moisture from the wood and form
sulfuric or hydrochloric acids in the firebox,
creating excessive corrosion.
NOTE: Do not use chemicals or fluids to start the
fire. Use kindling and a small amount of paper to
start an initial fire.
NOTE: This outdoor furnace is not to be used
with an automatic stoker.
WARNING
When adding wood to the firebox, be careful not
to get pinched between the wood and the door
frame, or any part of the outdoor furnace. Use
extreme care with large pieces of wood that may
be difficult to handle.
NOTE: The sight gauge valve should always be
closed, except when checking water level. Water
will automatically drain from the sight gauge tube
when the valve is closed. Remember that this type
of valve requires only 1/4 turn to open or close.
WARNING
Sulfuric acid in the test kit is a corrosive acid.
Handle carefully. Carefully read and follow
precautions on test chemical labels. Keep test
chemicals away from children. Safely dispose of
tested samples.
NOTE: A 40-watt
recommended if replacement is necessary. Do
not install a bulb in excess of 60 watts.
NOTE: In case of a power outage, either a
generator or 12V battery with a power inverter
can be used to provide electricity to operate the
outdoor furnace.
