Pilot Flame Pattern, Burner Flame Pattern | Desa VFRMV24NA specification

INSPECTING BURNERS

Check pilot ﬂ ame pattern and burner ﬂ ame patterns often.

PILOT FLAME PATTERN

Figure 22 shows a correct pilot ﬂ ame pattern. Figure 23 shows an incorrect pilot ﬂ ame pattern. The incorrect pilot ﬂ ame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.

If pilot ﬂ ame pattern is incorrect, as shown in Figure 23

•turn heater off (see To Turn Off Gas to Appliance, page 15 (Remote- Ready Models])

•see Troubleshooting, pages 19 through 21

Note: The pilot ﬂ ame on natural gas units will have a slight curve, but ﬂ ame should be blue and have no yellow or orange color.

BURNER FLAME PATTERN

Figure 24 shows correct burner ﬂ ame pattern.

NOTICE: Do not mistake orange ﬂames with yellow tipping. Dirt or other ﬁne particles are burned by heater, causing brief patches of orange ﬂame.

If burner ﬂ ame pattern is incorrect, as shown in Figure 25

•turn heater off (see To Turn Off Gas to Appliance, page 15)

•see Troubleshooting, pages 19 through 21

The ﬂ ames from the burner travel horizontally through the log set and emerge at the middle and rear of the set against the back logs.

The ﬂ ames are blue off the burner and as they progress through the log set, change to a light yellow color, yellow decorative ﬂ ames are visible as the ﬂ ames exit the log set.

The base of the log set and the underside of the top logs glow red. Natural gas models will burn with more blue ﬂ ame, while propane gas model will burn with bright yellow ﬂ ame.

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.
