Kalfire GP75/59F User Manual page 23

To refill the cartridge, open the glass panel, remove the log or charcoal covering the refill
opening, remove the cap and then follow the instructions on the packaging of the
container of Natural Spark Powder.
Possible reasons for an absence of sparks
If no sparks are generated, this could be due to the following reasons:
• The Natural Spark Powder cartridge is empty.
• There is no power supply to the NSG → check that the NSG is correctly connected (see
diagram below).
• The NSG pump and/or coil is defective → contact Kalfire.
