Step 5: Gas Piping and Connection

The gas piping must be installed in accordance with local codes or, in the absence of local codes, in accor- dance with the National Fuel Gas Code, ANSI Z223.1/ NFPA 54, latest edition.

The normal gas connection is 1/2” NPT, made at the left side facing the unit. If a right side connection is desired, the connecting pipe must be led at the rear of the fire- place to terminate at the left hand side for connection to the fireplace.

Piping should be tested for leaks prior to final wall installation. Test for leaks using soap and water solution after completing the connection. DO NOT USE OPEN FLAME.

Step 6: Optional Procedure For Cold Climate Instal- lations

The insulation and sealing of the enclosure around the fireplace is very important in cold climates. If the en- closure is insulated and sealed properly, you can avoid future cold air problems. The time taken to install the firebox correctly is well worthwhile. The following steps are to stop potential cold air problems.

Insulation of the Fireplace Enclosure

When in a chase or an outside wall, the fireplace en- closure should be insulated like any other wall of your home. Insulation should be installed on the outside wall(s) and the wall above the fireplace.

Insulate to Seal Under the Fireplace

Insulating under the fireplace is beneficial for installa- tions on a concrete slab. The fireplace should be placed on insulating board. It is important that a hard, rigid surface be maintained, so do not use fiberglass insula- tion for this purpose.

CAUTION: WHEN INSTALLING A FIREPLACE IN AN INSULATED ENCLOSURE, BE SURE TO MAINTAIN ALL MARKED AIR SPACES.

Seal Seams

Seal the seams of the fireplace where the outer wall meets the bottom pan and the front face. Also seal between the fireplace and finishing materials. Use high temperature caulk. Refer to Figure 7 for details of seal- ing spaces between the fireplace and finishing materi- als. Note the small amount of insulation installed across the top of the fireplace and down the sides as a backing for the caulk.

UVDR36C, UVDR42C specifications

CFM Corporation is a leading name in the world of efficient ventilation and air quality management, and its UVDR series, specifically the UVDR36C and UVDR42C models, stands out for their innovative features and advanced technologies. Designed for residential and commercial applications, these units are engineered to enhance air quality while ensuring energy efficiency.

The UVDR36C model is equipped with a powerful 36-inch UV-C air purifier that helps to eliminate airborne pathogens, viruses, and bacteria. This model utilizes ultraviolet light technology, which is proven to disinfect and purify air more effectively than traditional methods. Likewise, the UVDR42C offers a broader 42-inch purification coverage, catering to larger spaces or more demanding air quality needs.

Both models feature a robust filtration system that combines high-efficiency particulate air (HEPA) filters and activated carbon, trapping harmful particulates while neutralizing odors. The HEPA filters help to capture dust, pollen, pet dander, and other allergens, significantly improving indoor air quality. The activated carbon works to remove volatile organic compounds (VOCs) and other undesirable smells, promoting a fresher environment.

One of the standout characteristics of the UVDR series is their smart technology integration. These models are equipped with real-time air quality monitoring sensors, which adjust the purification levels based on the detected pollutants. This intelligent feature not only maximizes efficiency but also ensures that the air remains clean without unnecessary energy consumption.

Energy efficiency is a hallmark of the UVDR series. Designed to minimize power usage while maintaining optimal performance, both models operate quietly, making them ideal for homes, offices, and various commercial environments. This energy-efficient operation is complemented by an easy-to-use interface and user-friendly controls, allowing for seamless adjustments and monitoring.

The construction quality of both the UVDR36C and UVDR42C is robust, ensuring durability and longevity. With modern aesthetics, they fit seamlessly into any interior decor. Furthermore, maintenance is straightforward, with easy access to filters for replacement, making upkeep hassle-free.

Overall, the CFM Corporation UVDR36C and UVDR42C models represent a compelling choice for those seeking advanced air purification solutions. With their unique features, innovative technologies, and commitment to energy efficiency, CFM continues to set the standard in air quality management.
