The Honeywell Whole-House Ventilation System removes stale air and replaces it with fresh air. A centrifugal blowers brings fresh air into your home from outdoors and at the same time exhausts the stale air in an equal amount. Both the incoming and outgoing air streams pass through an exchange core where the energy from the exhaust air is efficiently transferred to the incoming air. In the winter, this means that the fresh air coming into the house is warmer than the cold air outdoors. In the summer, this means that the fresh air coming into the house is not as hot as the air outdoors. Vents in your home draw the stale air into the Honeywell Whole-House Ventilation System to be exhausted outside. After the heat and energy is exchanged, the fresh air brought in through the ventilator gets distributed in the house though the ducts of your heating or cooling system.

TrueFRESH™ Ventilation Systems

• Brings fresh air into the home, even when windows are closed
• Recovers up to 70% of the heat (in cold weather) or cooling (in warm weather) from the air leaving the home*
• Year-round ventilation – brings fresh air into the home, even when windows are closed
• 5-Year Warranty

Barometric Dampers

Safety & Efficiency Dampers:

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.

When to Use These Dampers?

Draft Inducers/Power Venters:

With these devices, draft is increased or created, causing fluctuations in air flow through the combustion chamber. These fluctuations can be negated by the use of a barometric draft control located between the draft inducer or power venter and the furnace, boiler, or water heater it services. Use a single-acting control for oil and gas-fired equipment with a power vented system. Use a single acting control for oil, and a double-acting control for gas-fired equipment with a draft induced system.

Power Burners:

A power burner is designed so that a fan delivers negative air pressure to the combustion chamber. A single-acting draft control for oil maintains that negative pressure. A power burner designed to burn natural or LP gas operates in the same manner. While a draft hood (diverter) is often used on gas units fired with an atmospheric burner, a double-acting barometric draft control should be used for furnaces or boilers fired with power burners.

Forced Draft Burners:

Forced Draft installed with a stack height in excess of 30′ will probably develop excessive natural draft, reducing the amount of pressure within the furnace or boiler. A barometric draft control will help eliminate this undesirable stack action and permit the unit to be pressurized.

Dual Fuel Appliances:

Burners capable of burning either gaseous fuels or oil should be equipped with a barometric draft control. We suggest using a double-acting control on units where fuels are frequently changed. The double-acting feature is important for gas-firing appliances because it allows spillage of combustion products in case of blocked flues or downdrafts. To detect flue gas spillage on dual fuel installation, a Field Thermal Safety Switch is recommended.

Gas-Fired Appliances:

Gas-fired furnaces and boilers generally require a double-acting draft control. Like a single-acting control, it opens inwardly to maintain a uniform draft. But, unlike a single-acting control, it is also free to open outwardly to spill the products of combustion, in case of blocked flues or downdrafts. National codes often mandate the use of a draft control. Usage is generally limited to furnaces or boilers designed for use with power burners and incinerators. Draft controls are generally used when oil-fired units are converted to gas.

Combustion & Fresh Air:

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-3, 4, 6 or 7 may be used to overcome the lack of air in a confined space. The CAS-3 is designed for use with oil appliances. The CAS-4 is for use with gas appliances with 24 VAC gas valve controls. The CAS-4MV is for use with 750mV power pile gas appliances. Each is designed for optimum safety and includes a proving device that won’t allow the burner to engage without the Fan-in-a-Can® operating. Multiple units or additional controls are required for multiple appliance installations. Each is equipped with a two speed control for enhanced versatility.

How The CAS (Fan-in-a-can) works: When the thermostat calls for heat, the Fan-in-a-Can® engages and begins drawing air into the structure. When air flow is established, the pressure switch closes. The CAS sends a signal to the appliance, allowing the burner to fire. The Fan-in-a-Can® diffuses the outside air into the room near the burner to ensure adequate air for efficient combustion.

Fresh Air:

Field Controls MAS Make-up Air Systems

Why Make Up Air Systems?

• To improve appliance efficiency.
• To improve Indoor Air Quality.
• To conserve energy.
• To increase fresh air changes.
• To replace air exhausted by bathroom fans, laundry dryers, range hood fans and other exhaust devices.

How It Works: The Make-Up Air System connects the HVAC system to the outside to allow controlled amounts of fresh air to enter the system when needed. The system automatically senses pressure changes and a need for air flow and opens to bring a precise, metered amount of fresh air into the air handler. Here the cold air is tempered as it mixes with warm air in the return duct. The air is then heated and distributed through the home via the central duct system. When the need for air is fulfilled, the system closes to prevent further air infiltration. The system must be installed by a qualified heating and air conditioning professional and is adjustable for homes from 1000 to 4000 square feet. It does not require any electricity or maintenance.

BROAN offers the widest variety of ventilation fans in the industry. For the latest high-performance, Energy Star qualified solution to today’s green building requirements, or ultra quiet operation for a comfortable environment, BROAN offers stylish options to fit any situation from a retrofit to a new build out. As the leader in residential ventilation, we will confidently meet your needs.

Homes are now built much more efficiently than they once were, making them far less costly to heat and air condition. That said, having proper ventilation throughout the home is now imperative in order to provide a safe and comfortable living environment. BROAN ventilation fans provide the best solutions to ensure that contaminants are constantly removed from the indoors.

High quality BROAN ventilation fans offer a variety of performance levels, functionalities and styles to suit each need in any area of your home. With air movement, sound levels and ENERGY STAR® qualified efficiency certified by the Home Ventilating Institute (HVI), you can trust that BROAN fans will serve at every level. BROAN fans function as BOTH traditional bath fan for removing humidity and odors on the spot, AND as continuously running fan to constantly remove contaminants trapped throughout the home. Problems such as humidity, odors, dust, pet dander, and various chemicals will be eliminated. This type of ventilation is referred to as “whole house” and is increasingly being required to meet building codes or to meet the requirements of green building programs such as LEED, ENERGY STAR® for Homes or the National Green Building Standard.
