Replacement parts

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 replacement part.
Results from using modified or other manufactured parts will not be covered by warranty and
may damage boiler or impair operation.

instructions on page 93 of this manual. Failure to comply could result in severe personal in-
jury.
Reinstall boiler jacket front door after startup or servicing
Inspect boiler jacket front door gaskets and reinstall boiler jacket front door after start or
servicing. The boiler front 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.
