Page 3: Swg/Cv Power Venter
SWG/CV POWER VENTER OUTDOOR MOUNTED POWER VENTERS FOR OIL & GAS 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.

Page 16: Vent Hoods
VENT HOODS All Field Vent Hoods are made of heavy .040 gauge aluminum and can be used with LP gas or oil-fired equipment. There are five diameters ranging from 3" to 8". The concentric pipe, angled outlet deflectors, and spaced plate design allow for better heat dissipation.
Page 17: Vent Caps
VENT CAPS The Star-Kap ® is the only vent cap that is not required to be two feet higher than any structure within ten feet when used on detached or lean-to buildings that house heating equipment outside of the living space. The unique design of the aluminized steel Star-Kap Vent Cap prevents downdrafts and assists the vent in drawing off and exhausting waste gases regardless of wind direction.

OIL VENT DAMPER PUT A DAMPER ON OIL HEATING BILLS Field’s Oil Vent Damper increases AFUE by up to 2%, which translates to a savings of approximately 5% to 10% per year on heating costs. See the chart for a quick reference of potential savings over five years on a typical mid-efficiency system.
Page 21: Thermal Safety Switches
THERMAL SAFETY SWITCHES Our thermal safety switches detect flue gas spillage due to a blocked flue. With the safety switch wired in series with the burner circuit, the switch will de-energize the system’s burner or burner control once it senses the spillage of hot flue gases. Available for gas-fired and oil-fired applications.

Page 23: Combustion Air Systems
COMBUSTION AIR SYSTEMS EFFECTS OF INSUFFICIENT COMBUSTION AIR ON DRAFT AND HEATING SYSTEMS For the proper operation and venting of gas or oil heating appliances, sufficient outside air must be supplied to the structure to make up for the air lost from venting heating appliances, fireplaces, clothes dryers, exhaust fans, and other building air losses. Insufficient combustion air can cause major problems for proper draft and operation of both gas and oil heating systems.
Page 24 COMBUSTION AIR SYSTEMS CAS-1 AND CAS-2 (OIL) Direct Connect The CAS-1 and CAS-2 Field Combustion Air Systems provide controlled amounts of outside air for proper combustion of oil heating appliances.

Page 25 COMBUSTION AIR SYSTEMS COMBUSTION AIR SOLUTIONS FOR ANY APPLICATION These models are designed to provide combustion air for appliances when direct connection to the burner is not possible (when the appliance is located in a confined space). According to NFPA 54 and NFPA 31, an engineered system such as a CAS-34U, 4, 6, or 7 may be used to overcome the lack of air in a confined space.

Page 29: Draft Control
DRAFT CONTROL 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.

Page 33 DRAFT CONTROL TYPE M+MG2 Solid, Oil or Gas Commercial/Industrial This is a series of compact, rugged, heavy-duty controls for use on large residential, commercial, and industrial applications. The Field Type M+MG2 Draft Control provides precise draft regulations for solid fuels, oil, gas, or oil/gas appliances requiring only the simplest, on-the-job adjustments depending on which fuel is to be utilized.
Page 34: Installation Options
DRAFT CONTROL INSTALLATION OPTIONS RECOMMENDED LOCATIONS FOR FIELD DRAFT CONTROLS For gas-fired equipment, the preferred location of the control is on the bull head tee. This location provides maximum relief of downdrafts with minimum positive pressure. (See Figure 1, Diagram A-C) With oil or solid fuels, the bull head tee is not recommended, so locate the control as shown.

Page 38: Open Hearth
OPEN HEARTH FLUE SENTINEL, THE OPEN HEARTH SOLUTION. ® For decades, we have been working to make our homes more energy efficient to conserve fuel and reduce energy costs. Loss of heat through an open chimney has become a concern in this energy conscious environment. Glass doors attempt to solve this problem but eliminate the hearth’s natural warmth and ambience.
Page 39 OPEN HEARTH ® THE FLUE SENTINEL HEALTHY HEARTH Flue Sentinel Damper ® Effectively closes the chimney when the hearth is not in use, preventing heat loss and downdrafts. Flue Sentinel Chimney Fan ® with Automatic Damper Fan provides constant flow of air to safely exhaust fumes.
