Measure new input rate (cover screw must be
installed). Repeat steps I.-IV until the input rate is
within +/-2% of the nameplate input rating.
If the actual input rate can not be set to within 2%
of the correct input rating by adjusting manifold
pressure, a change in gas orifice size is required.
Consult the boiler manufacturer for information on
correct orifice sizing. The specific gravity (G) and the
higher heating value (HHV) of the local natural gas
must be obtained from the local gas utility in order to
determine the proper orifice size.
Set Thermostat To Desired Room Temperature
Observe several operating cycles to verify proper operation.
