Operating instructions

B. GROUNDING
Permanently ground boiler according to local codes and the current edition of The National Electrical Code. Run a 14 gage or heavier copper wire
from boiler to a grounded connection in service panel or a properly driven and electrically grounded ground rod.
C. ELECTRICAL POWER SUPPLY
WARNING: Turn off electric power at fuse box before making any line voltage connections. Follow local electric
codes. Failure to follow this warning could result in electrical shock, personal injury, or death.
All electrical work must conform to local codes as well as the National Electrical Code. If not familiar with wiring and codes in general, have a
competent electrician do this job.
Boiler controls are all wired at the factory. All that is required is to connect a 115-v electric supply and thermostat wires to aquastat relay.
Run a separate circuit from a separate overcurrent protective device in electrical service entrance panel. This should be a 15-amp circuit. Locate
a shutoff switch at boiler. It must be turned OFF during any maintenance. Solder and tape or securely fasten these connections with wire nuts.
D. CONNECTING 115–V ELECTRICAL WIRING TO BOILER
Connect 115-v electric supply wires to terminals L1 and L2 on aquastat relay. (See Fig. 14.)
E. THERMOSTAT CONNECTIONS
The 2 wires from thermostat connect to terminals T and T on L8148A and L8124C aquastat relay (See Fig. 14.)
