STERLING QVF 24 VOLT SYSTEM

All these gas heaters are equipped with a 24 volt control system which is powered by a 115/24 volt transformer as standard equipment.

STERLING QVF GAS HEATERS FAN TIME DELAY

The fan time delay switch is mounted at the factory as standard equipment on all gas heaters. This feature eliminates an initial blast of cold air by allowing the unit to fi re for a short period of time before actuating the fan motor. After the thermostat is satisfied (with burners off) the fan continues to operate for approximately 1 minute, removing residual heat from the heat exchanger, an added economy feature.

STERLING QVF GAS HEATERS PACKAGE VALVE

On units 30,000 thru 400,000 BTU/HR (8.8 thru 117.1 kW) input, Sterling supplies a combination type gas valve which has a pressure regulator, shut off valve and main gas valve combined into one single valve. It also incorporates an automatic pilot safety switch and a blocked vent (spill) switch for 100% shutoff. Approved for use on all gases.

STERLING QVF GAS HEATERS ENERGY SAVING IGNITION CONTROL (Optional)

Spark ignition is available as an optional extra on these gas heaters. The pilot burner is ignited only during each cycle of operation, thereby conserving energy during the off cycle. Required for installation in California.

STERLING QVF GAS HEATERS ACCESS FOR MAINTENANCE

All Sterling gas heaters are so designed that the bottom pan can be dropped to expose the burners, pilot and orifices. Burners are individually removable for inspection and servicing. Pilot is also accessible through side panel access door on 100 thru 400 models.

STERLING QVF GAS HEATERS TEST FIRE

All Sterling gas heaters are test fired at the factory to insure proper operation at time of installation. The Sterling Gas-Fired Unit Heater is a complete heat generating and distributing plant equipped with automatic safety controls all packaged in a modern streamlined, space saving casing for mounting near the ceiling. Propeller gas heaters are low static pressure appliances. At no time should ductwork or 5-way nozzles be used with propeller units.

STERLING QVF GAS HEATERS 80% THERMAL EFFICIENCY

The designs are certified by C.S.A. International as providing 80% combustion efficiency. Approved for use in California when equipped with spark ignition.
