DOE Heating capacity is based on standard tests specifi ed by the United States Department of Energy.
All capacity ratings above are based on sea level. Input adjustments allow sett ing the high fi re input and may compensate for moderate altitudes.
For higher altitudes the maximum boiler input will be derated slightly.
Th e gas valve is capable of operating with natural gas or LP. See instructions in this manual to adjust for the specifi c fuel used.
For additional information, refer to the
200i Control manual.
Th ermostat anticipator sett ing is for a single thermostat connected to a single
200i
boiler. Also jumper from the Heat Demand terminals to the
IAR1 terminals on the connection board. See the 200i Control manual for details.
