NOTICE
Install 1/2” ground joint union (nut side down) as shown in Figure 8.1. Failure to do so will make
it difficult or impossible to remove burner for servicing.
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 ft. upstream of the boiler.
It is very important that the gas line is properly purged by the gas supplier or utility company.
