Operation and Control
The Harman XXV offers automatic ignition, room temperature control (targeting 70°F), and adjustable BTU output—up to 68,000 BTU with the P68 model—for optimal comfort․
Automatic Ignition System Explained
The Harman XXV pellet stove features a sophisticated automatic ignition system designed for reliable and convenient start-ups․ Upon power-up, the system initiates by feeding a small amount of pellets into the firepot․ An igniter then heats these pellets to their combustion temperature, initiating a flame․
The stove intelligently monitors the ignition process, and if ignition doesn’t occur within a set timeframe, it will repeat the process a few times․ Once a stable flame is established, the system gradually increases the pellet feed rate to build a robust fire․
Importantly, the appliance recognizes power restoration and resumes operation based on the ESP temperature․ For consistent performance, only Harman-approved battery back-up devices should be used, as others may not function correctly․
Room Temperature Mode: Achieving 70°F
The Harman XXV’s Room Temperature Mode offers a convenient set-and-forget heating solution, automatically maintaining a comfortable 70°F (21°C)․ When activated, the stove intelligently modulates pellet feed and blower speed to reach and sustain the desired temperature․
In this mode, the distribution blower operates at a medium speed, ensuring even heat distribution throughout the room․ The system continuously monitors the room temperature, adjusting the burn rate to compensate for heat loss and external temperature fluctuations․
This feature simplifies operation, eliminating the need for constant adjustments, and providing consistent warmth․ The P68 model, with its wide BTU range, excels in maintaining this setpoint efficiently․
Understanding BTU Output and Range (P68 Model)
The Harman P68 pellet stove is renowned for its exceptionally wide BTU (British Thermal Unit) output range, spanning from 0 to 68,000 BTU․ This expansive range provides unparalleled heating flexibility, adapting to diverse climate conditions and home insulation levels․
At the lower end, the P68 can operate at minimal heat output, providing gentle warmth during milder weather․ Conversely, at its maximum 68,000 BTU capacity, it delivers substantial heat for even the coldest environments․
Automatic operation simplifies usage; simply set your desired room temperature, and the P68 intelligently adjusts its BTU output to maintain that temperature, maximizing efficiency and comfort․
ESP Temperature and Appliance Response to Power Restoration
Upon power restoration, the Harman XXV pellet stove intelligently assesses the ESP (Exhaust System Temperature)․ This temperature dictates the stove’s restart procedure, ensuring safe and efficient operation․ If the ESP temperature is sufficiently low, the stove will initiate a normal restart sequence, automatically igniting and resuming heating․
However, if the ESP temperature remains elevated – indicating residual heat within the system – the stove will enter a cool-down mode․ This prevents immediate ignition, mitigating the risk of overheating or smoke generation․
The appliance will then monitor the ESP, restarting automatically once the temperature drops to a safe level, providing a seamless return to operation․
Power Management & Safety
This section covers minimizing smoke during power loss, utilizing Harman-approved battery backups, and emergency manual ignition procedures for safe operation․
Minimizing Smoke During Power Loss
During a power outage, the Harman XXV stove is designed to minimize smoke production, but proper understanding is crucial․ The appliance will attempt to continue operation utilizing residual heat, slowly reducing pellet feed․
However, incomplete combustion can occur, leading to some smoke․ Utilizing a Harman-approved battery backup system is highly recommended to maintain consistent operation and significantly reduce smoke․ Avoid repeatedly attempting manual ignition during a prolonged outage, as this can exacerbate the issue․
The stove will recognize power restoration and resume normal operation based on the ESP temperature․ It’s important to note that the appliance may require a brief restart period after power returns to fully optimize combustion and eliminate any lingering smoke․
Harman Approved Battery Back-Up Devices
To ensure optimal performance and safety during power outages, Harman strongly recommends using only their approved battery back-up devices․ These devices are specifically designed to seamlessly integrate with the XXV pellet stove’s control system, providing uninterrupted operation of essential functions like the auger and circulation blower․
Using non-approved devices may lead to improper operation, potential damage to the stove, or even safety hazards․ Harman-approved backups maintain consistent pellet feed and air circulation, minimizing smoke production and maintaining a comfortable room temperature․
Refer to the Harman accessories catalog or your local dealer for a list of compatible battery back-up models and installation instructions․ Proper installation is critical for reliable performance during power interruptions․
Emergency Manual Ignition Procedures
In the event of a prolonged power outage or automatic ignition failure, the Harman XXV pellet stove can be manually ignited․ This procedure bypasses the electronic ignition system, allowing for continued heating when power is unavailable․ However, manual ignition should only be used as a temporary solution․
First, ensure the hopper is filled with approved pellet fuel․ Then, carefully introduce a small amount of easily combustible material (like paper) into the firepot, alongside the pellets․ Light the material, allowing it to ignite the pellets․ Monitor closely until a stable flame is established․
Always exercise extreme caution during manual ignition, and refer to the full manual for detailed safety instructions and troubleshooting guidance․
