SETTING INPUT RATE
The furnace is shipped from the factory with #51 orifices.
They are sized for natural gas having a heating value of
1100 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
and orifice size required to fire each individual burner at
14,000 BTU/HR.
NOTE: Refer to the High Altitude Section of this manual
and the National Fuel Gas Code for high altitude rate ad-
justment above 2,000 ft.
