Flame Pack Series 400 Operation and Service Manual
20.0: Flame Pack Fuel
The Flame Pack uses a mixture of hydrogen and nitrogen as its fuel. Obtaining the correct mixture
is important as the instrument will not read correctly or may fail to function altogether with an
incorrect mixture. When fuel is purchased, it should be specified as follows:
FLAME IONIZATION FUEL GAS; 40% HYDROGEN/60% NITROGEN TOTAL HYDROCARBONS AS
CH4 LESS THAN 0.6 PPM
Due to the specialized nature of the equipment to produce this gas, it is not available from
Southern Cross Corp. it should be purchased directly from a specialty gas supplier such as NexAir,
Matheson, Scientific Gas Products, or Linde. Our experience has shown that mixtures purchased
from discount suppliers or welding shops are not always reliable and may cause the instrument
to malfunction. Some suppliers will furnish cylinders on a rental demurrage plan.
