WARNING
Prior to installation, ensure the specially designed single-
pipe vent adaptor end is smooth and chamfered to
prevent possible
damage to the sealing gasket of the boiler vent pipe
adaptor (coaxial).
Failure to comply could result in leakage, potentially
causing personal injury or death.
1. Apply small amount of water to end of single-pipe vent
adaptor to ease insertion.
2. Slide special single-pipe vent adaptor 1 fully onto
boiler vent pipe adaptor 2 . Do not apply excessive
force and/or bend single-pipe vent adaptor 1 when
inserting. Force could damage gasket.
IMPORTANT
The boiler vent pipe adaptor comes pre-installed for all
Vitodens 100-W and 200-W boilers.
