2.Attach the pilot gas line to the pilot out- let of the gas control valve and tighten. Connect the thermocouple to the rear of the gas control valve. See Figure 11. Do not overtighten. If using propane/LP gas, see Changing Pilot Orifice, page 11.

3.Install the inlet fitting into the inlet opening of the gas control valve (see Figure 12). Use thread sealant on the male pipe threads.

4.Place the burner pan assembly in the center of the fireplace floor. Make sure front of pan faces the room from which you wish to control the appliance.

5.Thread the gas supply fitting to the fire- place gas supply pipe. Adjust to most convenient position.

6.Install the gas connector tube to the gas supply fitting. Carefully shape tube to attach to adapter fitting. Be careful not to cause kinks in tube.

7.Test for leaks following instructions under Testing Burner for Leaks, page 11.

8.Retighten and adjust the location of the gas control as necessary. The gas con- trol should be level, with the control rod to the front.

9.Install cover, provided with log set, to burner pan using screws provided.

10.Install thermocouple, pilot, and ignitor onto valve cover as shown in Figure 13. Use the provided screws.

11.Push the control rod extension onto the “D” shaped control rod through the cen- ter hole in the cover.

12.Install the position decal and control knob making sure to align the marks with the correct stop positions of the gas control. Pilot position will allow the knob to push in about 1/2". Align the decals in the pilot position.

Propane/LP Gas Conversion

To convert to propane/LP gas, the burner inlet fitting and pilot orifice must be re- placed. The propane/LP burner inlet fitting is supplied with the orifice installed for a 24" log set. If you have an 18" set, you must change this orifice also. See Figure 1, page 3 for product identification.

Burner Inlet Fitting

1.Remove the burner inlet fitting from the burner pan assembly (see Figure 14). DO NOT remove the orifice from this fitting. The propane/LP burner inlet fit- ting is included in the hardware kit (see Figure 15).

2.Be sure to use the correct orifice for your appliance. The hardware kit included with this appliance contains two orifices with a cone-like shape. If you have an 18" set, the orifice for the burner inlet fitting is red. If you have a 24" log set, the orifice is already installed inside the fitting. The black orifice will not be used in any multi-side unit and may be discarded.

FVMR24, FVMR18 specifications

Desa FVMR18 and FVMR24 are innovative models that stand out in the world of HVAC (Heating, Ventilation, and Air Conditioning) systems. Designed for modern living and commercial environments, these units combine efficiency, performance, and advanced technology to meet diverse climate control needs.

The FVMR18 is designed for residential spaces, featuring a compact and sleek design that easily fits into various interior layouts. Its primary strength lies in its energy efficiency, boasting an impressive SEER (Seasonal Energy Efficiency Ratio) rating. This not only reduces overall power consumption but also minimizes utility bills, aligning with eco-friendly initiatives. The FVMR24, on the other hand, caters to larger areas, including commercial buildings, offering enhanced cooling and heating capabilities.

Both models utilize inverter technology, which allows them to adjust the compressor speed based on the ambient temperature. This means the units can operate more quietly and sustainably, delivering just the right amount of heating or cooling without the drastic fluctuations typical of conventional systems. The inverter technology also contributes significantly to the longevity of the unit, preventing wear and tear associated with frequent restarts.

A standout feature of both the FVMR18 and FVMR24 units is their advanced air filtration system. Equipped with HEPA filters, these models not only provide optimal temperature control but also ensure a clean and healthy indoor environment by capturing dust, allergens, and other airborne particles. This is particularly beneficial for those with respiratory issues or allergies.

Another key characteristic is the user-friendly interface, which includes a smart remote control and compatibility with smart home systems. This allows users to easily adjust temperatures, set timers, and monitor energy consumption through mobile applications. Additionally, both units are designed with quiet operation technology, ensuring minimal noise disruption, which is crucial in residential and office settings.

In summary, Desa FVMR18 and FVMR24 models represent a blend of cutting-edge technology and user-centric features. With their efficient performance, advanced filtration, and smart capabilities, they effectively address the diverse demands of contemporary climate control, making them a valuable investment for both home and business environments.
