1 - BEFORE STARTUP
Your Cleaver-Brooks boiler has been factory fire-tested and the control system pre-configured for a trouble-
free startup. To help ensure a successful lightoff and reliable operation, certain initial conditions should be
observed.
Do not attempt to place the boiler into service without verifying that all connections - fuel, steam and
water piping, electrical connections, stack, and combustion air provisions - have been installed properly
and in accordance with any applicable codes or regulations.
