Heat output and sound level

Both models provide 4 kW heat output under normal operating conditions and up to 5 kW during continuous operation at −40°C ambient temperature. Actual output depends on the selected level, ambient conditions, fuel quality and heater condition.

Manufacturer-reported sound level: 30–60 dB measured at a distance of 1.5 m. Sound varies with operating level and conditions.

Fuel and electrical supply

Diesel consumption: 0.10–0.38 L/h. Electrical power consumption during stable operation: below 40 W. Peak electrical demand during startup: approximately 95–105 W.

The listed heater voltage is 16.8 V DC; this is not a fixed external-source requirement. The approved external DC startup range is 12–28 V. Use an approved compatible source and the supplied lead. Before connecting another source, confirm the required continuous and peak current, connector, polarity and wiring instructions for the supplied configuration. Do not assume that every 12 V or 24 V supply is suitable.

Startup batteries and charging

Use four approved 26650A ternary lithium-ion startup cells. The manufacturer specifies 4.2 V and 5000 mAh (5 Ah) per cell. For battery startup, use fully charged cells and confirm that the displayed voltage is above 15.0 V. Check the supplied cell label and charger instructions; do not select replacement cells on the basis of size alone.

With the supplied charger, the manufacturer reports more than 90% charge in about 3 hours, sufficient for startup. Charging time depends on battery voltage and charging current; use the charger indication to assess charge. Obtain the approved replacement-cell and charger specification before replacing them.

Startup and self-generation

Install all four approved startup cells, including when using external power. If the cells cannot supply sufficient ignition current, also connect an approved external DC source as instructed in the manual. Keep the batteries installed for transitional support and safe shutdown.

The XL1906 thermoelectric module begins to contribute around 5 minutes after ignition. Around 10–15 minutes after startup, stable generation can cover the heater’s internal electrical demand across all heat levels 1–9 without battery discharge for normal running. Batteries can supply a shortfall during the transition. Timing depends on operating conditions; elapsed time alone does not prove stable self-powered operation. Keep the cells installed to support transition and safe shutdown if generation is insufficient or fails.

Disconnect an external source only as instructed in the manual: after stable ignition, maintain the connection for at least 5 minutes, confirm normal operation and confirm that the installed batteries can support the transition and shutdown. Keep the batteries installed. The minimum 5-minute connection period does not prove that battery discharge has stopped.

At 25°C ambient temperature, the manufacturer reports XL1906 laboratory generation of 15, 19, 25, 27, 31, 34, 36, 37 and 39 W at heat levels 1–9 respectively. These are generated-power observations, not net power available for USB devices or battery charging, and are not guaranteed output under all operating conditions.

Cold-weather preparation and normal shutdown

The heater’s operating ambient range is −40°C to +40°C. This refers to the heater’s surroundings, not the startup-cell temperature. Use diesel suitable for the expected temperature and follow the battery supplier’s temperature limits.

For startup at −40°C ambient temperature, do not attempt ignition with cells chilled to that temperature. With the heater off and cool, remove all four cells and gently warm them above 0°C, for example in protective cases inside clothing. Refit the warm, fully charged cells before startup. During operation the batteries are warm and remain installed; never remove them during operation or cooldown. Do not use flame or hot surfaces to warm cells.

Use ON/OFF for normal shutdown. The fan cools the heater for approximately 3–5 minutes. Keep batteries installed; they support safe shutdown if generation falls or fails. Wait until the fan stops and the LCD backlight goes out before switching off main power or disconnecting any remaining external supply. This completes electrical shutdown but does not prove that the exhaust is cool. Remove batteries, handle exhaust parts, move or pack the heater only after all parts have cooled.

Standard package and order configuration

The manual’s 14-item package list comprises: one heater; two air inlet/outlet ducts; two exhaust heat shields; one funnel; one remote controller; two colour-matched air-duct insulation sleeves; one M3 hex key; one battery charger; one exhaust elbow; two exhaust pipe sections; one external power lead; four approved 26650A startup batteries; one exhaust silencer; and one colour-matched storage bag.

The built-in fuel pump is standard. Confirm the final package for custom or bulk orders, including mounting hardware, installed battery configuration, total package weight and transport documents.
