†"C" dimension includes clearance to remove the burner. Do not put pipes, ducts, etc. in this area above the boiler.
*CSA minimum. Actual clearance depends upon stacking requirements.
**Service access need be only on one side of a boiler or row of boilers. Boilers may be installed immedi- ately adjacent to each other. However,
In Canada: The boilers are approved for installation with zero clearance to combustible surfaces, but 24 inch service clearances are recommended.
3.4ELECTRICAL CONNECTIONS
All field wiring connections for power and control are in the rear service panel on the back of the boiler. Low voltage and high voltage terminal strips are indi- cated on the wiring diagram. The boiler power circuit
