Finishing the Fireplace

There are a wide variety of ﬁnishing materials avail- able for your ﬁreplace from formal wall treatments with marble and mantels to rustic wood paneling, stone or brick.

IT IS IMPORTANT THAT THE BLACK FACE OF THE FIREPLACE NOT BE COVERED WITH ANY TYPE OF COMBUSTIBLE MATERIAL.

Noncombustible facing materials such as marble, brick or ceramic tile may overlap the black face of the ﬁre- place up to the opening on either side of the ﬁreplace. Seal all joints between the black ﬁreplace face and the wall covering with a heat-resistant material such as rock wool insulation or mortar. Be sure to use high tempera- ture adhesive or mortar when anchoring brick, stone or tile to the face of the ﬁreplace. Check to see whether man-made brick and stone are made of noncombustible materials before using them on the face of the ﬁreplace. Some of these products contain combustible materials. Combustible wall coverings such as paneling or wall- board may not overlap the black face of the ﬁreplace. The space between the wall covering and the ﬁreplace should be sealed with a heat-resistant material such as rock wool insulation or mortar.

NOTE: An “L” shaped steel lintel must be installed across the top of the ﬁrebox opening where facing materials such as brick or stone are used on the face of the ﬁrebox. It acts as a support/ﬁrestop. It should be attached to the face of the ﬁreplace with screws and sealed to the ﬁreplace with a heat-resistant sealer.

WARNING: The ﬁrebox screens must be in place be- fore operating the ﬁreplace.

WARNING: These vent free ﬁreplaces are not to be used with glass doors.

Pre-Wiring of Junction Box

Wiring should be connected at the junction box located on the right side of the ﬁrebox prior to the installation of the blower kit. A standard wall box should be used to contain the SCVS - Variable Speed Control Kit.

Electrical Services

If an electrical supply of 120V is being roughed in to the ﬁreplace junction box to provide for future installation of optional blower kit, the wiring should be connected to the junction box located on the right side of the ﬁrebox.

NOTE: All electric connections are to be made in ac- cordance with CSA Standard C22.1-Canadian Electrical Code part 1 or with the National Electrical Code, ANSI/ NFPA 70 (latest edition) and/or in accordance with local codes.

CAUTION: Should this blower require servicing, the power supply must be disconnected.

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.
