FAQ Q: Can I use fuels other than diesel? A: No! Please use diesel only, and high-quality diesel is advised. When transferring fuel from another container, avoid pouring any sediment from the bottom. Regularly check and clean any accumulated residue in the fuel tank. Q: Can I use an extension cord if the heater is far from my battery? A: It’s not recommended to use an extension cord for DC power. If necessary, use a wire rated at 18 AWG (1.024 mm diameter, approx. 0.823 mm² cross-section) or thicker, and ensure all connections are secure. Although the rated current is 3A, the startup current can reach 10–12A. Q: Can I use this heater indoors? A: Yes. However, the exhaust must be directed outdoors to prevent deadly carbon monoxide buildup. Never run the heater in an enclosed space without proper ventilation, as the exhaust contains harmful gases. Q: Can it be powered by a car cigarette lighter or a CB radio auxiliary outlet? A: No. These outlets often supply enough voltage but insufficient current, which can prevent ignition. The starting current can be as high as 12A. The heater requires 130 watts at 12 or 24 volts during start-up. The main power connection has to be made at a circuit designed to sustain this load without a voltage drop. Vehicle lighter sockets and auxiliary power outputs for C.B. radios and other electronic accessories are not considered adequate power supplies for the heater. Q: Can I use an AC to DC switching power supply? A: Yes, if it provides a stable 12V/24V DC output and can deliver at least 12A of current. We recommend using high-quality, well-known brands to avoid startup failure due to inaccurate ratings or control board damage due to unstable current. Q: Can I control multiple diesel heaters with one phone or remote? A: No. To prevent operational errors and ensure a stable connection, each remote is uniquely paired with a single heater (specifically the one included in the same package). Similarly, one phone can only connect to and contr
