Standard Equipment

CABINET

Base heater is indoor upright model, fabricated of 16 gauge Aluminized and/or CRS, heavily reinforced to assure rigidity, and backed  by an internal   radiation shield. Cooling air, traveling up both sides of the radiation shield, keeps the cabinet surface cool. Air inlets are screened. A pressure relief door and an observation port are provided on the end of the casing where the burner is mounted. The casing is primed and finished with a coat of enamel.

FAN ASSEMBLY

Fans- Forward curved, DWDI centrifugal fans tested in accordance with AMCA standards.

Shaft- Cold-rolled steel machined journals with first critical speed limited to at least 25% above maximum operating speed.

Bearings - 200, 000 Hour Self-aligning, pillow block, ball/needle  bearings.

ENERGY EFFICIENT MOTORS

Three phase, open dripproof  type on adjustable mount.

DRIVES

Fixed sheaves with V-belts safely enclosed within the air intake section.

HEAT EXCHANGER

Primary exchanger, all-welded 14 gauge 400 series stainless steel, designed for two passes and transfer of 75% of total heat release. Two staggered sections of black carbon secondary tubes insure maximum combustion efficiency.

FLUE GAS EXHAUSTER

Combustion gas exhaust system includes a heavy-duty exhaust fan, motor, adjustable V-belt drive and heat slinger.

ELECTRICAL

230/60/3 line current; 115/60/1 control current with transformer furnished for all voltages.

CONTROLS

Safety Control - Electronic sequencing burner safety relay with main and pilot flame sensing. Flame rod on gas; photo cell on oil.

MAIN BLOWER

Air Flow Switch - Prevents burner operation in the absence of air flow.

Prepurge Timer - Provides for continuous fan operation  and for burner shutdown.

Draft Switch - Insures operation of exhauster prior to ignition and burner shutdown on loss of draft.

Combustion Air Switch - Prevents burner operation in the absence of proper combustion air flow. (Not included with all oil burners.)

Burner Switch - Manually de-energizes burner circuit.

Blower Starter - Magnetic, three-phase, across the line.

NEMA 1 Master Control Panel.

Thermostat - Maintains desired space temperature utilizing On-Off space thermostat (for field mounting and wiring.)

BURNER

Standard burner is On-Off.

Gas (G) - Power type,  pilot spark ignition and main burner  pilot ignition for use with natural, manufactured, mixed liquefied petroleum  gas or liquefied gas/air mixture. Included in the manifold  are main gas electric shut off valve with linkage  to combustion air damper, main and pilot gas pressure regulators for maximum inlet pressure  of 1 PSI, pilot gas-air mixer  and pilot  solenoid valve. Minimum standard  entering pressure is 4 ozs.

Light Oil (LO) - High pressure oil atomizing  type with mechanically forced draft suitable  for burning fuels  through #2 grade  to a maximum  of 40 S.S.U. at 100 degrees F. The unit incorporates an oil pump, combustion  air fan and drive, combustion air damper operator, oil solenoid  valve, oil filter and pressure   gauge. An oil pressure regulator is supplied with a pressure system.

Gas/Light Oil (GLO) - Combination  fuel, power burner equipped with components as included with gas burner and light oil burner  described above. Automatic fuel changeover accomplished by means of an electric toggle switch in the burner control cabinet.

FACTORY TESTED

Factory piped, wired and flame tested.
