3. Position the gas control lever to 3 and move
on/off lever to “ON”. In cold conditions move gas lever higher, in warm conditions, lower.
4. Turn “ON/OFF” lever to “ON” position and ignite at ignition vent (Figure 3)
5. Wait until a glow is seen at the catalyst (seen through the ignition vent after about 4-5 seconds).
6. Close the ignition vent completely by raising the shutter lever (Figure 4). The flame will go out
and the gas will react with the catalyst producing heat.
7. The heat of the soldering and heat tips can be controlled by the gas control lever (Figure 5).
8. Extinguish by turning the gas “ON/OFF” lever to “OFF” until it clicks (figure 6).
