result in severe personal injury, death or

OBTAIN PARTS ONLY THROUGH
WEIL-McLAIN
Replacement parts must be purchased through a local
Weil-McLain distributor. When ordering, specify boiler model
and size and include description and part number of replace-
ment part. Results from using modified or other manufactured
parts will not be covered by warranty and may damage boiler
or impair operation.
THE BOILER CONTAINS CERAMIC
FIBER MATERIALS
The boiler contains ceramic fiber materials
. Use care when
handling these materials per instructions on page 94 of this
manual. Failure to comply could result in severe personal injury.
REINSTALL JACKET DOOR
Inspect boiler jacket door gaskets and reinstall boiler jacket
front door after start or servicing. The boiler door must be
securely 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.
Failure to keep the door securely fastened could result in severe
personal injury or death.
BEFORE SERVICING or MAKING
CONNECTIONS —
ALWAYS TURN POWER OFF TO THE BOILER TO
PREVENT ELECTRICAL SURGES, WHICH CAN DAM-
AGE BOILER COMPONENTS.
LABEL WIRES BEFORE REMOVING
Label all wires prior to disconnection when ser-
vicing controls. Wiring errors can cause improper
and dangerous operation.
