be in good condition, with no tears or gaps.
Replace if necessary.
Failure to keep the door securely sealed and
fastened could result in severe personal injury
or death.

change boiler behavior. After any maintenance
procedure, you must prove the boiler is oper-
ating correctly. To do so, follow the complete
procedure for boiler and system start-up,
beginning on page 84. Failure to comply
could result in severe personal injury, death
or substantial property damage.
