INSTALLATION

Installation and Clearences for Vent-free Operation (cont.)

INSTALLATION

Continued

Care fully follow the instructions below. This will ensure safe installation into masonary, UL127-listaed manufactured fireplace, or listed vent-free firebox.

Minimum Clearances For Side Combustible material, side wall, and ceiling

A. Clearances from the side of the fireplace cabinet to any combustible material and wall should follow diagram in figure 4.

Example: The face of a mantel, bookshelf, etc.. is made of combus- tible material must be 4" from the side of the fireplace to the cabinet (see figure 4).

B. Clearances from the top of the fireplace opening to the ceiling should not be less than 42 inches.

Example

*

*Minimum 16 inches from Side Wall

Figure 4 - Minimum Clearance for Combustible to Wall

NOTICE: Non thermostat controlled heaters maybe used as a vented product. If so, you must always run heater with chimney flue damper open, noncombustible material above the fireplace opening is not needed. Go to Installing Damper Clamp Accessory for vented operation.

Minimum Noncombustible material Clearences

If Not Using Mantel

Note: If using a mantel proceed to If Using Mantel. If not using mantel, follow the information on this page.

You must have non-combustible material(s) above the fireplace opening. Non-combustible materials (such as slate, marble, tile, etc..) Must be at least 1/2 inch thick. With sheet metal, you must have non-combustible material behind it. Non-combustible material must extend at least 8" up (for all models). If non-combustible material is less than 12", you must install the fireplace hood accessory (24" and 30" Models Only). See Figure 5 for minimum clearances.

If Using Mantel

You must have non-combustible material(s) above the fireplace opening. Non-combustible materials (such as slate, marble, tile, etc.) must be at least 1/2 inch thick. With sheet metal, you must have non-combustible material behind it. Non-combustible material must extend at least 8 inches up (for all models). If non-combustible material is less than 12", you must install the fireplace hood accessory (24" Models Only). Even if non-combustible material is more than 12", you may need the hood accessory to deflect heat away from your mantel shelf. See Figure 5 and Figures 6 and 7, page 9, for minimum clearances.

IMPORTANT: If you cannot meet these minimum clearances, you must operate heater with chimney flue damper open. Go to Installing Damper Clamp Accessory for Vented Operation, page 10.

VFRMV24NA, VFRMV18NA, VFRMV18PA specifications

The Desa VFRMV18NA, VFRMV18PA, and VFRMV24NA are advanced heating solutions designed to efficiently warm residential spaces while providing enhanced user comfort and convenience. These models are part of the VFRMV series, known for their reliability, innovative technology, and energy efficiency.

One of the main features of the VFRMV series is its variable refrigerant flow (VRF) technology. This allows the system to modulate the amount of refrigerant sent to each indoor unit based on the current heating or cooling load, resulting in optimal energy consumption. This flexibility not only saves energy but also ensures that the desired temperature can be quickly achieved and maintained across different rooms.

The VFRMV18NA and VFRMV18PA models are designed for residential use, with the VFRMV18PA specifically including additional features for enhanced performance in various climatic conditions. They come equipped with inverter-driven compressors, which adjust their speed to meet demand, leading to quieter operation and improved efficiency. This inverter technology ensures that energy consumption decreases during periods of lower demand, making these models environmentally friendly and cost-effective.

The VFRMV24NA model, with its higher capacity, is suitable for larger spaces or homes needing additional heating and cooling power. Like its counterparts, it features a high SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings, indicating its efficiency in energy use, which translates into savings on energy bills for homeowners.

In terms of characteristics, all three models incorporate user-friendly controls, allowing homeowners to easily adjust settings and schedule operations. Smart technology integration enables remote monitoring and control via mobile apps, giving users the ability to manage their indoor climate on the go.

Additionally, the VFRMV series features advanced filtration systems that improve indoor air quality by capturing dust and allergens, making these models an excellent choice for households with allergy sufferers. The units are also designed with sleek, modern aesthetics, ensuring they blend seamlessly with a variety of interior designs.

In summary, the Desa VFRMV18NA, VFRMV18PA, and VFRMV24NA offer cutting-edge technology, impressive efficiency, and user-friendly features. With their VRF technology, inverter-driven compressors, and smart controls, these heating solutions provide an ideal choice for homeowners seeking comfort, efficiency, and convenience in their indoor environments.
