CFV Startup Guide
Part No. 750-288 3
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.
1.1 Operating Conditions
• The installation site should be as free as possible from vibration,
dust, and corrosive media
• The controllers should be located as far as possible from sources of
electromagnetic fields, such as frequency converters or high-voltage
ignition transformers
• Control panel must be connected to earth ground. For electrical
wiring requirements, see wiring diagram provided with the boiler or
in the CFV manual.
