Placing the Boiler in Operation
This chapter describes the initial start-up procedure for
the G125 BE boiler irrespective of the employed control
system.
z
Please fill out the start-up protocol during this pro-
cess (
Î
Chapter 8.11, page 46).
Further information regarding boiler room lay-out and
clearances, combustion air requirements and venting
system as well as boiler operational requirements, refer-

Chapter 3.2, page 8.
8.1
Setting the Initial System Pressure
Set the system for regular operation during the initial
start-up procedure.
z
Add additional make-up water until the desired pres-
sure is achieved; at least 12 - 15 psi, but no more
than 30 psi. (Actual settings are dependent on the
pressure rating of the relief valve).
CAUTION!
BOILER DAMAGE
from excessive dust and air contamination.
z
Do not operate the boiler under high
dust conditions, such as sheet rock
dust and construction dust. Make sure
to provide clean combustion air if the
boiler needs to operate under such con-
ditions.
z
Install an air filter, or other means to en-
sure clean combustion air. Dust can
originate from within during construc-
tion, but also from outside when the in-
stallation is in close vicinity of chemical
plants, shop or dusty outside condi-
tions.
