Mag 20 Furnace Assembly, Operation and Parts

Assembly

The main body of your furnace is fully assembled and factory-tested. To facilitate packag-

ing, the valve rod and operating lever have not been factory-installed and you must do so,
prior to using the furnace as follows: Attach the operating lever spring to the operating lever.
Slide the valve rod on the operating lever as shown in Figure 19. Next, place the valve rod
and operating lever, into position as shown in Figure 20. Fasten the operating lever using the
furnished 5/8" 6/32" screw. Insert the lever adjusting screw and hex locknut as shown. Your
furnace is now ready for use.
Handling Lead

Lead, a substance known to cause birth defects, reproductive harm and other severe physi-

cal injury, must be handled with extreme care. Handle lead bullets or lead shot only in a well
ventilated area and ALWAYS wash hands after handling lead and before eating. Discharging
firearms in poorly ventilated areas, cleaning firearms, or handling ammunition, also may
result in exposure to lead. Have adequate ventilation at all times.

Figure 19.

Figure 20.

WARNING: Melting lead and casting lead objects will

expose you and others in the area to lead, which is known to

cause birth defects, other reproductive harm and cancer.

REDUCING EXPOSURE:

Lead contamination in the air, in dust, and on your

skin is invisible.

Keep children and pregnant women away during use and until cleanup is complete.
Risk can be reduced — but not eliminated — with strong ventilation; washing hands imme-

diately after use of these products before eating or smoking; and careful cleaning of surfaces
and floors with disposable wipes, after lead dust has had a chance to settle. Use a lead spe-
cific cleaner with EDTA, or a high-phosphate detergent (like most detergents sold for electric
dishwashers) and bag used wipes for disposal.

Use Strong Ventilation
