Install Instructions

Maintenance
Disconnect power
Electrical shock hazard — Disconnect all
electrical power to the boiler before attempting
maintenance procedures. Failure to complete
could result in severe personal injury, death or
substantial property damage.
Re-install boiler jacket door after
startup or servicing
Reinstall boiler jacket door after start-up or
servicing. The boiler jacket door must be se-
curely fastened to the boiler to prevent boiler
from drawing air from inside the boiler room.
This is particularly important if the boiler is
located in the same room as other appliances.
Inspect boiler jacket door gaskets on front of
cabinet. Gaskets must be in good condition,
with no tears or gaps. Replace if necessary.
Failure to keep the jacket door securely sealed
and fastened could result in severe personal
injury or death.
Start-up and check/out
Removing and reinstalling components can
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 75. Failure to comply
could result in severe personal injury, death
or substantial property damage.
DO NOT SERVICE THE BOILER
WITHOUT A ECO MAINTENANCE
KIT AVAILABLE
The ECO maintenance kit includes components that may
have to be replaced when accessing or disassembling parts
of the boiler.
Failure to replace damaged components and to use only
the parts specifically intended for the boiler can result
in severe personal injury, death or substantial property
damage.
See Figure 109, page 107 for part number.
