If pilot ﬂame pattern is incorrect, as shown in Figure 53, page 27

•turn ﬁreplace off (see To Turn Off Gas to Appli- ance, page 23 for Thermostat-Controlled Mod- els or page 25 for Remote-Ready Models)

•see Troubleshooting, page 30

Note: The pilot ﬂame on natural gas units will have a slight curve, but ﬂame should be blue and have no yellow or orange color.

BURNER FLAME PATTERN

Figure 54 shows a correct burner ﬂame pattern. Figure 55 shows an incorrect burner ﬂame pattern. The incorrect burner ﬂame pattern shows sporadic, irregular ﬂame tipping. The ﬂame should not be dark or have an orange/reddish tinge.

Note: When using the ﬁreplace the ﬁrst time, the ﬂame will be orange for approximately one hour until the log cures.

If burner ﬂame pattern is incorrect, as shown in Figure 55

•turn ﬁreplace off (see To Turn Off Gas to Appli- ance, page 23 for Thermostat-Controlled Mod- els or page 25 for Remote-Ready Models)

CLEANING AND

MAINTENANCE

WARNING: Turn off ﬁreplace and let cool before cleaning.

CAUTION: You must keep control areas, burner, and cir- culating air passageways of ﬁreplace clean. Inspect these areas of ﬁreplace before each use. Have ﬁreplace inspected yearly by a qualiﬁed service person. Fireplace may need more frequent cleaning due to excessive lint from carpeting, pet hair, bedding material, etc.

WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property damage.

BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE

The primary air inlet holes allow the proper amount of air to mix with the gas. This provides a clean burning ﬂame. Keep these holes clear of dust, dirt, lint, and pet hair. Clean these air inlet holes prior to each heating season. Blocked air holes will create soot. We recommend that you clean the unit every three months during operation and have ﬁreplace inspected yearly by a qualiﬁed service person.

We also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recommend using compressed air no greater than 30 PSI. Your local computer store, hardware store, or home center may carry compressed air in a can. You can use a vacuum cleaner in the blow position. If using com- pressed air in a can, please follow the directions on the can. If you donʼt follow directions on the can, you could damage the pilot assembly.

1.Shut off the unit, including the pilot. Allow the unit to cool for at least thirty minutes.

2.Inspect burner, pilot, and primary air inlet holes on injector holder for dust and dirt (see Figure 56, page 29).

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.
