OPERATING HEATER

Continued

Note: Do not leave the hand-held remote in the AUTO mode close to the fireplace. The radiant heat from the fireplace will turn off the fireplace. Ideally, place the hand-held remote in the center of the room facing towards the fireplace. Note: Do not hold the hand-held remote for a long time. Body temperature will affect its operation in the AUTO mode.

Safety Features When away from home for an extended period of time or as a child safety feature to prevent accidental ignition of the fireplace, the receiver ON/OFF/REMOTE switch should be in the OFF position.

Auto Shutoff Feature

1.If the average room temperature exceeds 82 degrees Fahrenheit (28 degrees Centi- grade), the hand-held remote control will perform a safety override and shut the fireplace off. This feature is not available in the MANU mode.

2.The receiver continuously receives signals from the hand-held remote to control the room temperature. If the hand-held remote is misplaced, obstructed or for any reason cannot transmit to the receiver, the receiver will shut off the fireplace after 8 minutes.

Key Pad Lock Feature This feature allows the user to lock/unlock the keypad on the hand-held remote in the MANU or AUTO mode to prevent inadvertent operation (i.e. children operating the hand-held remote control, etc.). The keypad is locked in either on or off. Press the POWER and LOCK buttons together to turn the unit on or off.

INSPECTING BURNERS

Check pilot flame pattern and burner flame pat- terns often.

PILOT FLAME PATTERN

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

If pilot flame pattern is incorrect, as shown in Figure 23

•turn heater off (see To Turn Off Gas to Appli- ance, page 17)

•see Troubleshooting, page 22

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

VFRMV24PA, VFRMV18PA, VFRMV18NA, VFRMV24NA, VFRMV24PA specifications

Desa's VFRMV series is a line of advanced heating solutions designed for energy efficiency and optimal comfort. The series includes models VFRMV24PA, VFRMV18PA, VFRMV18NA, VFRMV24NA, and VFRMV24PA. Each model is tailored to meet different heating demands, making them suitable for various residential and commercial applications.

One of the defining features of the VFRMV series is its inverter technology, which adjusts the compressor speed to match the heating or cooling needs of the environment. This capability not only enhances energy efficiency but also contributes to a quieter operation. Users can expect significant energy savings, as the inverter technology minimizes energy consumption during periods of low demand.

Each model in the VFRMV series boasts high-performance SEER and HSPF ratings, indicating superior energy efficiency and performance. With such ratings, these units are designed to make substantial contributions to reducing heating and cooling costs while complying with modern environmental standards.

The VFRMV24PA and VFRMV24NA models are particularly effective in larger spaces, offering robust heating capacities while remaining energy efficient. On the other hand, the VFRMV18PA and VFRMV18NA models cater to medium-sized spaces, ensuring that homes or offices maintain a comfortable atmosphere without overspending on energy bills.

Additional characteristics include advanced filtration systems that improve indoor air quality by removing dust, allergens, and pollutants. This feature is particularly beneficial for allergy sufferers or anyone keen on maintaining a healthier living environment.

Moreover, the VFRMV series incorporates smart home compatibility, allowing users to control their heating and cooling systems remotely via smartphone apps. This feature not only adds convenience but also enables better energy management, as users can adjust settings based on their schedules or occupancy patterns.

In summary, Desa's VFRMV series, comprising models VFRMV24PA, VFRMV18PA, VFRMV18NA, VFRMV24NA, and VFRMV24PA, offers a blend of efficiency, performance, and advanced technology. The use of inverter technology, high SEER and HSPF ratings, robust heating capabilities, advanced filtration, and smart home features make these units ideal choices for anyone looking to enhance comfort while minimizing energy expenses.
