For proper operation and efficient fuel consumption in oil, gas, and/or coal-fired heating appliances, draft must remain constant. When it is, combustion is more complete, fuels are utilized efficiently, and money is saved. Field Draft Controls maintain consistent draft by counteracting the negative forces caused by changes in temperature and barometric pressure, as well as the effects of wind.

The field RC is furnished as standard equipment on many leading brands of oil or coal-fired heating equipment. It is calibrated to allow for easy adjustment to the furnace or boiler manufacturer's specifications. Designed for settings from 0.02 - 0.08 Inch, this control is so sensitive that instrumentation should be used when adjusting the unit during installation.

JUNIPER ELBOW COMPANY
Field Controls (GVD) gas vent damper was developed to reduce off cycle venting losses through boilers and draft hoods. When the boiler is in a standby mode, heat escapes up the chimney. The heat comes from the boiler and the conditioned space. To significantly reduce these losses, install a Field Controls Gas Vent Damper. The damper is installed in the vent as close to the draft hood as practical. When properly installed, the damper opens before the burner fires, and closes after the burner shuts off. The electrical circuits in this product are designed not to override the existing limit and safety controls of the boiler.
  • Operates with all 24 VAC , 60 Hz intermittent ignition and standing pilot ignition systems
  • Stainless steel construction provides superior corrosion resistance
  • Damper operation - power opens in 15 sec, power closes in 15 sec, power is off at damper motor when it is at rest
  • Hold open switch allows damper to be placed in an open position and taken out of service to assist with trouble shooting appliance problems
  • Keyed wiring harness connector plug installs only one way, preventing incorrect wiring connection
  • Flex seal provides self cleaning action

Field Controls SWG-4HDS Stainless Steel Power Venter, 4", 115 VAC at 60 Hz, 1.7 amp, 138 watt The safest, most efficient power venter available today. Gas and oil heating appliances generate heat through the combustion of fuel. The heat is transferred through the heat exchanger and distributed to the conditioned space. The products of combustion, however, must be vented safely out of the structure. In a conventional chimney, venting is achieved by the natural lifting action of the hot combustion gas. New, efficient systems absorb more of the heat in the heat exchanger and produce lower temperature vent gas. Lower temperature gas does not rise as quickly or as reliably as in older, less efficient systems. Power venting or sidewall venting is more economical and safer than chimney venting. A power venter uses a motorized blower to vent the products of combustion. A power venter is interlocked with the appliance to ensure that proper draft is achieved before the appliance burner is activated.
  • 100% negative pressure in the vent pipe for maximum safety
  • Standard galvanized pipe can be used instead of expensive stainless steel
  • No need to seal vent pipe joints, saving time and money
  • Significantly longer vent lengths than positive pressure, direct vent systems
  • The SWG is recommended by major heating appliance manufacturers
