WARNING: All gas piping and connections must be tested for leaks after the installation is com- pleted. After ensuring that the manual shutoff gas valve is open, apply a soap and water solution to allconnectionsandjoints. Ifbubbles appear, leaks can be detected and corrected. DO NOT USE OPEN FLAME FOR LEAK TESTING AND DO NOT OPERATE ANY APPLI- ANCE IF A LEAK IS DETECTED.

GAS SUPPLY TESTING

Note: This section is intended as a guide for qualified technicians installing gas to this vent-free firebox.

CAUTION: Do not connect vent-free heater before pressure testing gas piping. Damage to gas valve may result and an un- safe condition may be caused.

The appliance and its shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).

The appliance must be isolated from the gas supply piping system by closing manual shutoff valve during any pressure testing of the gas supply piping system at test pres- sures equal to or less than 1/2 psig (3.5kPa).

HARD-WIRING FIREBOX

Model FBPS can be hard-wired to the du- plex outlet located inside the firebox bottom if desired. This allows the blower accessory to be plugged into the duplex outlet.

NOTICE: A qualified electrician must connect electrical wiring to duplex outlet for built-in in- stallation. Follow all local codes. In absence of local codes follow The National Electric Code ANS/ NFPA 70.

ELECTRICAL INSTALLATION

A model GA3500A blower system assembly is available for use with the FBPS vent-free firebox as an optional accessory. This blower is designed to be installed on the wall side of the FBPS firebox, when provisions for a 120 VAC supply connection are made at the end of the cabinet. Use of a blower system other than those manufactured by DESA Interna- tional voids the warranty.

Electrical connections are made within the receptacle with wires that are routed through the bushing provided (see Figure 15). The receptacle may be relocated to either side, when necessary. However, the cover plate must be replaced over the unused access point. Be certain to properly ground the vent-free firebox using the green grounding wire (see Figure 17 on page 12).

Note: A 120V supply connection to the leads to the receptacle must be provided for use with the optional blower kit whether installed during or after initial firebox in- stallation. You may not be able to install a supply connection after the final installation is completed. Refer to Optional Blower As- sembly Installation on page 12 for specifics.

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.
