If burners that have
been in use for some time give off a yellow flame, it is probable that
the trouble is caused by a deposit of soot or burned material. Such
burners should be removed, boiled in a solution of washing soda or lye
until the holes in the top are thoroughly cleaned, and then replaced and
adjusted. As long as the flame remains yellow, the gas is not giving off
as much heat as it should produce and is liable to smoke cooking
utensils black. Therefore, to get the best results the burners should be
thoroughly cleaned every now and then in the manner mentioned. Likewise,
the pan beneath the burners, which may be removed, should be cleaned
very frequently, and the entire stove should be wiped each time it is
used, for the better such a stove is taken care of, the better will it
continue to do its work.

71. FIRELESS-COOKING GAS STOVES.--A style of gas stove that meets with
favor in many homes is the so-called fireless-cooking gas stove, one
style of which is shown in Fig. 7. Such a stove has the combined
advantages of a fireless cooker, which is explained later, and a gas
stove, for it permits of quick cooking with direct heat, as well as slow
cooking with heat that is retained in an insulated chamber, that is, one
that is sufficiently covered to prevent heat from escaping.
