Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)

1.Close equipment shutoff valve (see Fig- ure 7).

2.Pressurize supply piping system by either using compressed air or opening main gas valve located on or near gas meter.

3.Check all joints from gas meter to equip- ment shutoff valve (see Figure 7). Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak.

4.Correct all leaks at once.

HEARTH KIT ASSEMBLY AND INSTALLATION

Kit Assembly

1.Unscrew burner inlet fitting from burner manifold.

2.Place burner manifold in pan with threaded opening facing open knock- out plug (see Figure 8). Make sure the burner ports face downward.

3.Using thread sealant (resistant to the action of propane/LP gas) on larger end of fitting, screw the burner inlet fitting through hole and into burner manifold. Tighten using a wrench. If using propane/LP gas, see Propane/LP Gas Conversion, pages 10 and 11.

4.If using optional GA9000 kit, go to Op- tional GA9000 On/Off Safety Valve/Pi- lot Kit section for installation instruc- tions. If using optional GA9100 kit, follow instructions included with kit for installation and operation.

5.Using thread sealant on the male threads, install the burner connection fittings into the 1/8" NPT holes on each side of the burner manifold.

6.Press the right and left side burners onto the burner connection fittings. The burner porting should face downward (see Figure 8).

Installation and Gas Connection

1.Place the burner pan assembly in the center of the fireplace floor. Make sure the inlet end of the pan faces the gas supply.

2.Thread the gas supply fitting to the fireplace gas supply pipe. Use thread sealant.

3.Install adapter fitting onto the burner inlet fitting using thread sealant on male threads of burner inlet fitting (see Figure 9). Adjust to most conve- nient position.

4.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.

5.Using the 1/4" x #8 provided, install the cover over the inlet fitting.

OPTIONAL GA9000 ON/OFF SAFETY VALVE/PILOT KIT ASSEMBLY

For additional convenience and safety, or for propane/LP conversion, an optional ON/ OFF safety valve/pilot kit is available. See Accessories, page 19.

WARNING: You must use a ON/OFF safety valve/pilot kit for propane/LP conversion.

Note: The control cover provided with the GA9000 should be discarded and replaced with the one provided with the log set.

Natural Gas Installation

1.Thread the gas control valve onto the burner inlet fitting (see Figure 10). Use thread sealant on the male threads of the burner inlet fitting. Hold the burner inlet fitting with a wrench to prevent overtightening the connection to the burner. Make sure the control rod is facing the front (see Figure 10).

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.
