Attention! Read Before Use!
For outdoor use only. Not For use by minors or
individuals under the influence of alcohol or drugs. Place on level ground, on
loose dirt or sand.
Note: Hairline cracks in
the refractory are normal. The same way a sidewalk has joints for expansion &
contraction during extreme temperature change.
Never leave unattended for any reason during operation. Turn furnace off.
Always pour molten metal on sand or dirt floor. Molten metal spills on concrete floor causes dangerous results from trapped moister in the concrete.
Do not operate near anything flammable. During use, never introduce anything to the melt (Liquid metal) that has not been preheated first.
A cold item placed into the molten metal will cause splattering and dangerous splashing of molten metal! Do not use if not familiar with propane and or propane appliances. Need help? Call Steve at 509-487-6832 or your local propane dealer.
Personal Protection- Safety glasses- Always wear proper eye protection.
Gloves assume everything is hot! Always wear gloves. Shoes- shoes with laces are dangerous, cover-laced area.
1. Place crucible inside furnace and metal inside the crucible loosely, metal packed tightly will expand during heating and crack the crucible.
Use wood matches to light furnace. Turn on gas at regulator and simultaneously drop match inside furnace, in front of burner outlet inside the furnace. For easy lighting: place a small piece of wood soaked in lighter fluid directly in front of burner inlet (inside the furnace), light the wood and then release the gas into the furnace.
If flame goes out, turn gas off immediately!
Adjust gas to a loud roar. A “whup… whup” sound is an indicator of too much or too little pressure. If the flame blows out, use less pressure. Run gas at ½ pressure for 2-3 minutes to warm-up. Gas pressure should be full throttle when hot.
3.Bring metal to pouring temperature
Additional Cautions Do not open lid during operation, turn furnace off.
During operation have the lid plug out. Use plug only when furnace is off to hold heat inside. When installing the burner, hand tighten only, do not use tools.
Do not over heat the crucible.
Furnace flame should not directly strike the crucible! Move to the side and
rotate often to extend crucible life. Furnace flame should not hit the crucible
“tipping hole”.
When melting aluminum, after the last piece turns molten, let furnace run 3
more minutes to reach pouring temp. Then shut furnace off. for brass, 5 minutes.
If metal does not melt in 1 hour, it will not melt (most likely steel).
