The furnace is shipped from the factory with #42 orifices.
They are sized for natural gas having a heating value of
1050 BTU/cu. ft. and a specific gravity of .60.
Since heating values vary geo-graphically, the manifold
pressure and/or gas orifice size may need to be changed
to adjust the furnace to its nameplate input. Consult the
local gas utility to obtain the yearly average heating value
