STANLEY STN125D Multi-Fuel Forced Air Heater
KEROSENE/PARAFFIN FORCED AIR HEATER QUICK-START GUIDE
Thank you for purchasing a STANLEY forced air heater. Please keep your User’s Manual for future reference and seasonal servicing recommendations. For optimal performance, STANLEY recommends that K-1 kerosene/paraffin be used, especially in temperatures lower than -3°C (26°F). If K-1 kerosene/paraffin is not available, these other fuels may be used: #1/#2 diesel/fuel oil, JET A, or JP-8. Never use “off road” diesel, fuel additives, or fuel alternatives. This is an unvented portable heater. It uses air (oxygen) from the area in which it is used. Adequate combustion and ventilation air must be provided. Please read the User’s Manual very carefully and understand all warning statements. The manual has been designed to instruct you on the proper operation, maintenance, and storage of your new heater.
How to Get Your New Heater Quickly Up and Running
-
Familiarize yourself with all safety instructions in the front of your User’s Manual.
-
Remove the heater from the box. Ensure all parts are included and assembled per the instructions.
-
Remove any protective material applied to the heater for shipment.
-
Check the heater for damage. If damage is found, contact the service partner.
-
Before filling the fuel tank for the first time, remove any moisture or condensation.
-
When filling the fuel tank, use at least 8 liters (2 gallons) of fuel. Ensure the heater is on a level surface and do not overfill. Ensure the fuel cap is tightened.
-
Plugin the heater to a minimum 1.8 m (6-foot), 0.75 mm2 (ST-45-KFA-E and ST-70T-KFA-E models) or 1.5 mm2 (ST125T-KFA-E – ST-215T-KFA-E models), 3-prong grounded extension cord.
-
Turn on the heater, and set the temperature controller higher than the ambient temperature. A few seconds after the fan starts running, the heater will ignite. Only use this heater in a well-ventilated outdoor space!
NOTE: Smoke or flames may be briefly seen from the end of the heater after being turned on for the first time. Louder than normal noise from the unit, as well as a hot smell, should subside after a few minutes of initial operation. -
If needed, you can adjust the pump pressure to get the heater to run at maximum efficiency. Due to varying fuel consistencies and changes in elevation, the fuel pump may require a simple adjustment. This will get your heater working at an optimum level. You will need a screwdriver and your User’s Manual. If any of the following scenarios happen after the first few minutes of initial operation, turn off the heater, unplug it, and wait for the heat to subside.
