Field Controls DI-1

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

A double-acting control for gas-fired furnaces and boilers is widely used for conversion burner installations, gas draft-induced appliance operation with mechanical draft inducers or sidewall power venters. It is also recommended for use on gas atmospheric appliances where a draft hood cannot be installed and can improve combustion stability and draft on many gas atmospheric installations with venting problems. The MG-1 provides precise, accurate control of drafts at levels higher than permitted by a standard draft diverter, which is a frequent requirement with gas. Because it is double-acting, it opens out to relieve positive vent system pressures as low as 0.01" draft adjustments using weights are simple and accurate from 0.01 - 0.1".
