Never use gasoline, naphtha, paint thinners, alcohol or other highly flammable fuels. 6 099623 VENTILATION OPERATION WARNING Follow the minimum fresh, outside air ventilation requirements. If proper fresh, outside air ventilation is not provided, carbon monoxide poisoning can occur. Provide proper fresh, outside air ventilation before running heater. Provide a fresh air opening of at least 2800 square cm (three square feet) for each 29,3 kW (100,000 Btu/Hr) rating. Provide extra fresh air if more heaters are being used. Example: A 44 kW (150,000 Btu/Hr) heater requires one of the following: • a 4,88 m (16 foot) wide two-car garage door raised 8,59 cm (3.38 inches) • a 2,75 m (9 foot) wide single-car garage door raised 15,24 cm (6 inches) • two, 76,20 cm (thirty-inch) wide windows raised 28 cm (11 inches) WARNING Review and understand the warnings in the Safety Information Section. They are needed to safely operate this heater. Follow all local codes when using this heater. To Start Heater 1. Follow all ventilation and safety information. 2. Fill fuel tank with kerosene or No. 1 fuel oil. 3. Attach fuel cap. 4. Plug power cord of heater into standard 230 volt/50 hertz, grounded (earthed) outlet. Use an extension cord if needed. Use only a grounded (earthed) extension cord. Extension Cord Wire Size Requirements Up to 100 feet (30.5 meters) long, use 16 AWG (1.0 mm2) conductor 101 to 200 feet (30.6 to 61 meters) long, use 14 AWG (1.5 mm2) conductor Heater will start when power cord is plugged into outlet.

Unplug power cord from outlet. To Restart Heater 1. Wait 2 minutes after stopping heater. 2. Repeat steps under To Start Heater, page 7. Note:If shipping, transport companies require fuel tanks to be empty. 1. Drain fuel tank. Note:Some models have drain plug on underside of fuel tank. If so, remove drain plug to drain all fuel. If heater does not have drain plug, drain fuel through fuel cap opening. Be sure all fuel is removed. 2. Replace drain plug if provided. 3. If any debris is noted in old fuel, add 1 or 2 quarts of clean kerosene to tank, stir, and drain again. This will prevent excess debris from clogging filters during future use. 4. Replace fuel cap or drain plug. Properly dispose of old and dirty fuel. Check with local automotive service stations that recycle oil. 5. If storing, store heater in dry place. Make sure storage place is free of dust and corrosive fumes. IMPORTANT:Do not store kerosene over summer months for use during next heating season. Using old fuel could damage heater.
