Installing GAS Line

UNVENTED (VENT-FREE) LOGMATE® FIREBOX

INSTALLATION

Continued

WARNING: A qualified service person must connect heater to gas supply. Follow all local codes.

IMPORTANT: See Connecting to Gas Sup- ply in your log set owner’s manual for details on gas hookup.

Figure 11 shows the typical installation for the gas line. When you have determined how the gas line will run, locate the recessed knockout in the firebrick floor (see Figure 12). Firmly tap the center of the knockout with a chisel until it is released. Carefully chisel the rough edges of the hole you have made to smooth edges. This hole will line up with the hole in the metal floor.

CAUTION: Do not use exces- sive force to remove the knock- out. Too much force may dam- age the firebrick concrete insert.

Gas Line Installed Through Access Hole on One Side of Firebox

A manual shutoff valve, AGA certified and complying with the National Fuel Gas code, ANS Z223.1-latest edition, must be included within (6') six feet of the vent-free firebox gas supply system. It may be convenient to install the gas shutoff outside the vent-free firebox enclosure where it can be accessed with a key through a wall as shown in Figure

13.Depending on the type of installation, some local codes may require you to install two (2) manual shutoff valves independently accessible from both rooms. Check your local codes for applicable installation re- quirements.

A 36" long 1/2" NPT SCHD 40 flexible gas connector line complying with the National Fuel Gas code ANS Z223.1-latest edition, may be run from the regulator to the incom- ing 1/2" NPT black iron gas line. You may also route the incoming 1/2" NPT black iron gas line directly to the appliance regulator.

Remove the gas line cover plate from the vent-free firebox’s outer surround and route the gas line into the rear of the firebox (see Figure 11).

If a sediment trap is not incorporated as a part of the gas utilization equipment, one shall be installed as close to the inlet of the equipment as practical at the time of instal- lation, as per ANS Z223.1-latest edition. See Figure 14, page 11.

Prepare incoming black iron gas line with Teflon tape or pipe joint compound (check with local codes as to the use of Teflon tape). Compounds used on threaded joints of gas piping shall be resistant to the action of pro- pane/LP and should be applied lightly to en- sure excess sealant does not enter the gas line.

Complete your gas installation by connect- ing the incoming gas line to the appliance regulator. Secure all joints tightly with wrench but do not overtighten. If a flexible gas line is used, take care not to kink the connector.

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.
