PART II. 
CORRECT USE 12 OF MANUFACTURED GAS. 
METHODS OF UTILIZATION DETERMINE QUALITY OF SERVICE PRODUCED- 
Gas service is radically different from every other kind of public- 
utility service in that the gas can not be used by the consumer as re- 
ceived, but — 
First , must be mixed in proper proportion with another substance, 
atmospheric air. 
Second , this mixture must then be completely burned. 
Third , the flame must be so directed that the heat generated will 
effectively get into the food, air, water, or mantle that is being 
heated, with a minimum loss. 
The results obtained will depend primarily on the gas-utilization 
appliance and the consumers’ skill and care in operating. All these 
operating features are beyond the gas company’s control, but are 
vital in determining the quality of the service produced by one con- 
sumer and the effect on the service of other consumers. Women, as a 
class, do not take easily to manual matters involving mechanical ad- 
justments; so these facts, therefore, make obvious the need of educa- 
tion in the correct use of gas in the home. To meet this service 
situation, gas companies should give demonstrations and teach con- 
sumers correct and safe use of gas. 
ABSENCE OF GAS-APPLIANCE REGULATIONS. 
Much money and effort have been spent in developing and enforc- 
ing standards of gas quality. However, it has not been appreciated 
that the type of appliance and method of use are of much more con- 
sequence in determining the kind of service the consumer can get 
than the specific quality of gas delivered to the appliance . 13 
WHAT MUST HAPPEN WHEN GAS IS BURNED. 
The combustion — that is, the burning of manufactured gas — can 
take place only by first mixing the gas with the proper proportion of
