CAUTION
•
Support the weight of the gas line piping independently from the boiler gas connection
fitting located on the bottom of the boiler.
•
If an additional regulator is used to reduce boiler inlet pressure below 1/2 psig (3.4 kPa) it
must be at least 6 to 10 feet upstream of the boiler.
•
It is very important that the gas line is properly purged by the gas supplier or utility
company.
