WARNING- RISK OF FIRE:
• Do not operate with flue draft exceeding .08 water column inches (19.9 Pa).
• Do not operate with fuel loading door or ash drawer open.
• Do not store fuel or other combustible materials within marked installation clearances.
• Inspect and clean flues and chimney regularly.
DANGER: Risk of Fire and Explosion. Do not burn garbage, gasoline, naphtha, engine oil, or other flammable liquids/inappropriate
materials.
WARNING:
• NEVER use galvanized pipe in your chimney connection, it produces poisonous gases when subjected to extreme
temperatures.
• USE only lined masonry or manufactured Class “A” HT2100 All Fuel Chimney for your furnace.
• INSPECT chimney system periodically for structural integrity.
• CLEAN the chimney system regularly to prevent creosote accumulation.
• DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.
Duct
Runs
Ductwork should be designed so the external static pressure does not exceed .02 water column inches while developing air velocities
of 450 - 600 feet per minute at the registers. The heat outlet area should never be less than 10 inches round or 79 square inches. The
furnace can be installed with a cold air return system, or the return air can be drawn from the basement. If the return air is drawn from
the basement, you will have to install 3 “open and close” air register vents in the return air duct connected to your existing furnace; the
air will take the path of least resistance without using ductwork to connect the two together. The return air system should be a minimum
of 10% larger than the heat outlet to readily transfer the cold air back to the furnace. Avoid using 90° elbows in duct runs; 45° elbows
provide better airflow and less resistance. CAUTION: The warm air supply outlet of the supplementary furnace should not be connected
to the cold air return inlet of the central furnace, because a possibility exists for components to overheat and cause the central furnace to
operate other than intended.
