SYSTEM FURNISHED. REFER TO THE TABLE BELOW FOR THE FIGURES IN THIS MANUAL APPLICABLE
TO THE VARIOUS CONTROL SYSTEMS OFFERED AS STANDARD OR AS OPTIONAL EQUIPMENT. IF THE
CONTROL SYSTEM ORDERED IS NOT LISTED, SPECIAL INSTRUCTIONS HAVE BEEN PREPARED BY THE
APPLICATION ENGINEERING DEPARTMENT AND CAN BE FOUND IN THE INSTRUCTION ENVELOPE
FURNISHED WITH THE BOILER.

Open Gas Controls Carton(s)
NOTE: On those boilers with two manifolds (15 sect. and larger), two identical sets of Gas Controls are furnished. Hence,
the procedure for installing one set is equally applicable to the second set.

In the absence of requirements of the authority
having jurisdiction, the tables below may be used to
size natural gas supply piping.

Pressure testing of the Gas Supply Piping Boiler and
its connections is required before placing the boiler
in operation.
The boiler and shutoff valve must be disconnected
from the gas supply piping system during any
pressure testing at pressures greater than ½” psig.
The boiler must be isolated from the gas supply
piping system during any pressure testing at
pressures equal to or less than ½ psig.
WITH GAS SUPPLY “OFF” and Service Piping
connected to the boiler, open Manual Valve(s) and
pilot valve(s) at end of Gas Train(s) and reduce
pressure to ½ lb. gage pressure. Using soap solution
or other approved method check gas train piping,
