DETERMINING FRESH-AIR FLOW FOR FIREBOX LOCATION

Determining if You Have a Confined or Unconfined Space

Use this work sheet to determine if you have a confined or unconfined space.

Space: Includes the room in which you will install firebox plus any adjoining rooms with doorless passageways or ventilation grills between the rooms.

1.Determine the volume of the space (length x width x height).

Length x Width x Height = ________ _________ cu. ft. (volume of space)

Example: Space size 22 ft. (length) x 18 ft. (width) x 8 ft. (ceiling height) = 3168 cu. ft. (volume of space)

If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume of the space.

2.Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space can support.

_____________ (volume of space) ÷ 50 cu. ft. = (Maximum Btu/Hr the space can support)

Example: 3168 cu. ft. (volume of space) ÷ 50 cu. ft. = 63.3 or 63,300 (maximum Btu/Hr the space can support)

3.Add the Btu/Hr of all fuel burning appliances in the space.

*Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors.

4.Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.

______________ Btu/Hr (maximum the space can support)

______________ Btu/Hr (actual amount of Btu/Hr used)

Example: 63,300 Btu/Hr (maximum the space can support) 79,000 Btu/Hr (actual amount of Btu/Hr used)

The space in the above example is a confined space because the actual Btu/Hr used is more than the maximum Btu/Hr the space can support. You must provide additional fresh air. Your options are as follows:

A.Rework work sheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoin- ing room or add ventilation grills between rooms. See Ventilation Air from Inside Building, page 6.

B.Vent room directly to the outdoors. See Ventilation Air from Outdoors, page 6.

C.Install a lower Btu/Hr gas log heater, if lower Btu/Hr size makes room unconfined.

If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconfined space. You will need no additional fresh air ventilation.

WARNING: If the area in which the firebox and gas log heater may be operated is smaller than that defined as an unconfined space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code, ANS Z223.1, 1992, Section 5.3 or applicable local codes.

FBPS specifications

Desa FBPS, or Flexible Building Production System, is an innovative approach to construction that leverages advanced technologies to enhance efficiency, sustainability, and adaptability in building design and construction. This system is gaining traction in the industry due to its versatility and ability to integrate new methodologies suitable for various construction environments.

One of the main features of Desa FBPS is its modular design. This allows for the construction of buildings using pre-fabricated components, which can be assembled on-site with minimal disruption. This modularity not only speeds up the construction process but also reduces waste, as components are manufactured in a controlled environment where precision and quality can be more easily maintained.

Another significant characteristic of Desa FBPS is its use of smart technologies. The system incorporates IoT (Internet of Things) devices, enabling real-time monitoring of building conditions, energy consumption, and other critical parameters. This data-driven approach facilitates timely decision-making and maintenance, improving the overall longevity and functionality of the buildings.

Sustainability is a core principle of Desa FBPS. The system prioritizes eco-friendly materials and energy-efficient designs, often utilizing renewable energy sources and advanced insulation technologies. This focus on sustainability not only lowers the carbon footprint of construction but also results in long-term savings on energy costs for occupants.

Desa FBPS also emphasizes flexibility in design. Buildings constructed using this system can be easily expanded or modified to adapt to changing needs. This flexibility is particularly advantageous in urban areas where space is at a premium and evolving residential or commercial demands necessitate rapid responses from developers.

Additionally, the integration of Building Information Modeling (BIM) technology plays a crucial role in Desa FBPS. BIM allows for the visualization of a building throughout its lifecycle, facilitating better planning, collaboration among stakeholders, and improved project management.

In summary, Desa FBPS represents a paradigm shift in construction practices, characterized by modular design, smart technology integration, sustainability, and design flexibility. Its forward-thinking approach positions it as a leader in modern construction, addressing the growing demands for efficient and adaptable building solutions in a rapidly evolving world.
