CLEANING AND MAINTENANCE

WARNING: Turn off heater and let cool before cleaning.

WARNING: Failure to keep the primary air openings of the burner clean may result in sooting and property damage.

CAUTION:Youmustkeepcontrolareas,burners,andcirculating air passageways of heater clean. Inspect these areas of heater be- fore each use. Have heater inspected yearly by a qualiﬁed service person. Heater may need more frequent cleaning due to excessive lint from carpeting, pet hair, bedding material, etc.

CLEANING BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE

The primary air inlet opening allow the proper amount of air to mix with the gas. This provides a clean burning ﬂame. Keep these holes clear of dust, dirt, lint, and pet hair. Clean these air inlet opening prior to each heating season. Blocked air opening will create soot. We recommend that you clean the unit every three months during operation and have heater inspected yearly by a qualiﬁed service person.

We also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recommend using compressed air no greater than 30 PSI. Your local computer store, hardware store, or home center may carry compressed air in a can. You can use a vacuum cleaner in the blow position. If using compressed air in a can, please follow the directions on the can. If you don't follow directions on the can, you could damage the pilot assembly.

1.Shut off the unit, including the pilot. Allow the unit to cool for at least thirty minutes.

2.Inspect burner, pilot, and primary air inlet opening on injector holder for dust and dirt (see Figure 26).

3.Blow air through the ports/slots and holes in the burner.

4.Check the injector holder located at the end of the burner tube again. Remove any large particles of dust, dirt, lint, or pet hair with a soft cloth or vacuum cleaner nozzle.

5.Blow air into the primary air opening on the injector holder.

6.In case any large clumps of dust have now been pushed into the burner repeat steps 3 and 4.

Clean the pilot assembly also. A yellow tip on the pilot ﬂame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about two inches from where the pilot ﬂame comes out of the pilot assembly (see Figure 27). With the unit off, lightly blow air through the air inlet hole. You may blow through a drinking straw if compressed air is not available.

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.
