NOT restore electric power and gas supply until installation
and inspection have been completed (in order to prevent the
main burners from operating). DO NOT operate the boiler until
the vent damper harness "RECEPTACLE B" is plugged into
"MALE PLUG" (as described in the installation instructions),
and the vent damper installation and checkout procedures
have been completed. Failure to observe this warning may
create a hazardous condition that could cause an explosion or
