The INFERNO switch heater is recommended for clearing ice and snow from switches with no longer than 22 ft of moving rail from heel to point of switch. It is rated with an output of 350,000 BTU/HR, on propane or natural gas. The fan is direct driven at 2840 rpm and delivers 1100 scfm.

Two standard duct system configurations are available. One for yards where the ballast is level with the top of tie and the other for raised track.

FIRING SPECIFICATIONS

ELECTRICAL SPECIFICATIONS

• 120Vac / 9.5 amps max start up / 4.5 run amps / single phase / 60 Hz

CONSTRUCTION

• 14 ga galvanized steel blower, intake, and duct work
• Stainless steel combustion chamber / transition duct
• Direct drive motorized impeller

CONTROLS

• Direct Spark Ignition System.
• Thermostatically controlled trackduct nozzle outlet temperature, 340 - 380°F.
• Remote operation, requires a set of contacts rated for a minimum 120Vac, 0.1 amp.
• Remote run indication, provided by a set of normally open contacts rated at 8 amps resistive or 2 amps inductive, 240/120Vac or 24Vdc

GAS CONVERSION

• For use with propane gas. To convert to natural gas adjust within specifications detailed above.
• Reverse procedure to change back to original gas.

GAS SUPPLY

• Recommended supply gas pressure, 8 - 14 in. H20, with all connected loads operating.
• The gas valve will not open against supply pressures in excess of 14 in. of H2O (1/2 psi).
• Inlet gas fitting, 3/4" NPT male.

SAFETY FEATURES

• Air pressure (flow) switch: Ignition is disabled until adequate air pressure is developed.
• High temperature limited: In the event of thermostat failure and nozzle temperatures exceeding 420°F, the heater is shut off to avoid tie damage. Heater operation is restored by manual reset.
• Loss of flame: The Ignition Module closes the gas valve, if after the trial for ignition period of 6 seconds no flame is sensed, or if flame detection is lost for more than 1 second during normal operation.
