FRESH AIR FOR COMBUSTION AND VENTILATION

WARNING

WARNING ICON

G 001

 

 

This heater must have fresh air for proper operation. If not, poor fuel combustion could result. Read the following instructions to insure proper fresh air for this and other fuel-burning appliances in your home.

Today’s homes are built more energy efficient than ever. New materials, increased insulation, and new construction methods help reduce heat loss in homes. Home owners weather strip and caulk around windows and doors to keep the cold air out and the warm air in. During heating months, home owners want their homes as airtight as possible.

While it is good to make your home energy efficient, your home needs to breathe. Fresh air must enter your home. All fuel-burning appliances need fresh air for proper combustion and ventilation.

Exhaust fans, fireplaces, clothes dryers, and fuel burning appliances draw air from the house to operate. You must provide adequate fresh air for these appliances. This will insure proper venting of vented fuel-burning appliances.

PRODUCING ADEQUATE VENTILATION

All spaces in homes fall into one of the three following ventilation classifications: 1. Unusually Tight Contruction; 2. Unconfined Space; 3. Confined Space.

The information on pages 5 through 8 will help you classify your space and provide adequate ventilation.

Unusually Tight Construction

The air that leaks around doors and windows may provide enough fresh air for combustion and ventilation. However, in buildings of unusually tight construction, you must provide additional fresh air.

Unusually tight construction is defined as construction where:

a.walls and ceilings exposed to the outside atmosphere have a continu- ous water vapor retarder with a rating of one perm or less with open- ings gasketed or sealed and

b.weather stripping has been added on openable windows and doors and

c.caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and at other openings.

If your home meets all of the three criteria above, you must provide addi- tional fresh air. See Ventilation Air From Outdoors, page 8.

If your home does not meet all of the three criteria above, continue reading.

Unconfined Space

An unconfined space has a minimum air volume of 50 cubic feet for each 1000 BTU/Hr input rating of all appliances in the space (cubic feet equals length x width x height of space). Include adjoining rooms only if there are doorless passageways or ventilation grills between the rooms.

Confined Space

A confined space has an air volume of less than 50 cubic feet for each 1000

 

BTU/Hr input rating of all appliances in the space (cubic feet equals length x

 

width x height of space). Include adjoining rooms only if there are doorless

 

passageways or ventilation grills between the rooms.

VN6B, VN12A specifications

The Vanguard Heating VN6B and VN12A represent cutting-edge solutions in residential heating technology. Designed to meet a variety of heating needs, these systems combine efficiency and user-friendly features, catering to an increasingly eco-conscious market.

The VN6B model is ideal for smaller homes or spaces, boasting a compact design without sacrificing power. It uses advanced condensing technology, which allows it to achieve impressive efficiency ratings. With an Annual Fuel Utilization Efficiency (AFUE) of up to 96%, the VN6B maximizes heat output while minimizing fuel consumption. This leads to significant cost savings on heating bills, making it an attractive choice for homeowners looking to upgrade their heating systems.

Meanwhile, the VN12A is built for larger areas, providing robust heating solutions for bigger residential spaces. With similar condensing technology, it features an AFUE rating that matches its smaller counterpart, ensuring that it also operates with remarkable efficiency. The VN12A is engineered with a modulating burner, which adjusts the flame size according to the building’s heating needs. This means it can operate quietly and smoothly, offering comfort without the jarring temperature fluctuations that other systems may create.

Both models incorporate innovative safety features, including a built-in flue gas condensation sensor that ensures safe operation under varied conditions. Additionally, they include a user-friendly digital thermostat, which enables precise temperature control and can be programmed for optimal efficiency. Homeowners can easily customize their heating schedule, making it convenient to maintain a comfortable living environment while also conserving energy.

Another notable characteristic of the Vanguard VN6B and VN12A is their durable construction. Made from high-quality materials, these heating units are designed to withstand wear and tear, ensuring a long lifespan with minimal maintenance. Regular maintenance reminders are a feature, making it straightforward for homeowners to keep track of service needs.

In summary, the Vanguard Heating VN6B and VN12A models stand out in the market for their exceptional efficiency, smart technologies, and user-centric features. They are excellent choices for homeowners seeking reliable and environmentally friendly heating solutions that promise comfort year-round, all while keeping energy costs low.
