INSTALLATION

Continued

CAUTION: Make sure exter- nal regulator has been installed between propane/LPsupply and fireplace. See guidelines under Connecting to Gas Supply, page 16.

PRESSURE TESTING GAS SUPPLY PIPING SYSTEM

Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)

1.Disconnect appliance with its appliance main gas valve (control valve) and equipment shutoff valve from gas supply piping system. Pressures in excess of 1/2 psig will damage heater regulator.

2.Cap off open end of gas pipe where equipment shutoff valve was connected.

3.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve located on or near gas meter for natural gas, or using compressed air.

4.Check all joints of gas supply piping system. Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.

5.Correct all leaks at once.

6.Reconnect fireplace and equipment shutoff valve to gas supply. Check reconnected fittings for leaks.

Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)

1.Close equipment shutoff valve (see Figure 26).

2.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve located on or near gas meter for natural gas, or using compressed air.

3.Check all joints from gas meter to equipment shutoff valve for natural gas or propane/LP sup- ply to equipment shutoff valve for propane/LP (see Figures 27 or 28). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.

4.Correct all leaks at once.

PRESSURE TESTING FIREPLACE GAS CONNECTIONS

1.Open equipment shutoff valve (see Figure 26).

2.Open main gas valve located on or near gas meter for natural gas or open propane/LP supply tank valve.

3.Make sure control knob of fireplace is in the OFF position.

4.Check all joints from equipment shutoff valve to gas regulator (Thermostat-Controlled Models), or to gas control valve (Remote- Ready Models) (see Figures 27 or 28). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.

5.Correct all leaks at once.

6.Light fireplace (see Operating Fireplace, page 22). Check all other internal joints for leaks.

7.Turn off fireplace (see To Turn Off Gas to Appli- ance, page 23 for Thermostat-Controlled Mod-

els or page 25 for Remote-Ready Models).

CDCFTNA, CDCFPR, CDCFTPA specifications

Desa CDCFTPA, CDCFPR, and CDCFTNA represent a suite of advanced technologies and methodologies employed in the development and management of efficient distribution networks within the field of telecommunications and data services. These frameworks are designed to enhance connectivity, streamline processes, and ensure optimal performance in various environments.

One main feature of Desa CDCFTPA (Coaxial Digital Channel Fiber Transmission Protocol Architecture) is its ability to integrate coaxial cables with fiber optic technology, enabling high-speed data transmission over existing infrastructures. This hybrid approach not only reduces the need for extensive renovations but also capitalizes on the advantages of both technologies, offering broadband accessibility and improved bandwidth capabilities. By leveraging both mediums, operators can deliver enhanced services while maintaining cost-efficiency.

CDCFPR (Centralized Data Control Fiber Processing Resource) represents a centralized approach to managing data flow within telecommunications networks. Its core characteristic lies in its architecture, which supports dynamic allocation of resources in real-time. This enables network operators to efficiently allocate bandwidth based on demand, optimize routing paths, and reduce latency. Additionally, CDCFPR employs advanced algorithms for data compression and encryption, ensuring that users experience a seamless and secure connection.

CDCFTNA (Carrier Digital Channel Fiber Transmission Network Architecture) is focused on creating robust networks that can support a variety of distribution channels, including 5G and IoT devices. Its design emphasizes scalability and adaptability, allowing network providers to easily expand or modify their infrastructure to meet evolving market needs. Key technologies incorporated in CDCFTNA include Software-Defined Networking (SDN) and Network Function Virtualization (NFV), which enable operators to manage their resources more flexibly and efficiently.

Each of these frameworks boasts unique characteristics that contribute to the overall enhancement of telecommunications systems. They embody a commitment to innovation, sustainability, and user-centric design, aligning with current trends in digital services and communication technologies. By deploying such advanced systems, service providers can ensure they remain competitive in a fast-paced and continuously evolving market. In summary, Desa CDCFTPA, CDCFPR, and CDCFTNA collectively represent the future of telecommunications infrastructure, promising improved connectivity, efficiency, and adaptability for a diverse range of applications.
