Thank you for purchasing a Master forced air heater. Please keep your User's Manual for future reference and seasonal
servicing recommendations.
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.
For optimal performance, Master recommends that K-1 kerosene be used, especially in temperatures lower than 20°F
(-6°C). If K-1 kerosene is not available, these other fuels may be used: #1 diesel/fuel oil or JET A. Never use "off road"
diesel, fuel additives, or fuel alternatives.
How to Get Your New Heater Quickly Up and Running
1. Familiarize yourself with all safety instructions in the front of your User's Manual.
2. Remove the heater from the box. Ensure all parts are included and assemble per the instructions. If you are
missing parts, do not take the heater back to the store—call us at 800-779-3267.
3. Remove any protective material applied to the heater for shipment.
4. Check the heater for damage. If damage is found, contact us at 800-779-3267.
5. Before filling the fuel tank for the first time, remove any moisture or condensation.
6. When filling the fuel tank, use at least 2 gallons (8 liters) of fuel. Ensure the heater is on a level surface and do not
overfill. Ensure the fuel cap is tightened.
7. Plug in the heater to a minimum 6-foot, 14-gauge, 3-prong grounded extension cord.
8. Turn on the heater, and set the temperature controller higher than the ambient temperature. The heater will go
through a pre-check cycle that takes about 30 seconds on initial startup. After the cycle is complete, the heater will
ignite after the fan starts running. 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.
9. 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.
Problem

have a consistent flame
or will not stay lit.
The heater produces
