COMMERCIAL OIL-FIRED WATER HEATERS
FEATURES
MEETS THE THERMAL EFFICIENCY AND STANDBY LOSS REQUIREMENTS
ASHRAE/IESNA 90.1
LIME TAMER™ MODELS INHIBIT LIME AND SEDIMENT BUILDUP
models are warranted against tank failure due to sedimentbuildup for three years.
GLASSLINED TANK — Maximizes tank life. 160psi working pressure.
180° ADJUSTABLE THERMOSTAT— Has upper and lower sensingbulbs to average water
temperatures at top and bottom of heater formaximum temperature control (120°-180°).
SAFETY SHUTOFF— Limits temperature buildup.
UL LISTED OIL BURNER— Precision engineered to match the units they are used with; designed
to fire 1.75 to 5.0 gallons of oil per hour. All models equipped with single phase continuous duty motor
120 volt AC60 Hz, 3450 rpm with manual overload switch and interrupted ignition. Standard burners
equipped with single stage pump with 1 or 2 line capability. Flame retention principle assures high rate
of combustion efficiency, yet maintains low operating noise levels. Fuel unit includes pump, strainer,
pressure regulating valve and ignition transformer. Transformer rated at 120 volt AC, 60 Hz with 10,000
volt secondary, UL listed for use with No. 1 and 2 commercial grade fuel oil. Burner mounted cadmium
cell relay for flame detection - 15 second safety switch timing eliminates the need for RA890F Electronic
Safeguard. Complies with UL A708.5-32/33.
EFFICIENT COMBUSTION CHAMBER—
of alumina silica ceramic fiber. Engineered for maximum insulation and heat reflection. Unique design
assures more complete combustion by stabilizing flame pattern.
INTERRUPTED IGNITION— Reduces electrical consumption.
OIL SOLENOID SAFETY VALVE— Standard on COF-455 and 700.
3/4” DRAIN VALVE— Provided in lower tank for fast draining.
TWO HAND-HOLE CLEANOUTS—Allows easy cleaning on standard models COF-385 and
larger and ASME models.
ANODIC PROTECTION—For longer tank life.
FLAME OBSERVATION PORT—Permits convenient flame check.
FOAM INSULATION—Saves fuel, helps maintain constant temperature.
JACKET—Heavy gauge steel with baked enamel finish over bonderized undercoat. Not
approved for installation on combustible flooring.
EASY TO INSTALL BURNER—Three bolt mounting of burner assures easy installation.
