There are two telescopic sections, the terminal assembly and the
connection assembly, a roll of sealing tape and two self-tapping screws.
A 93° elbow is also supplied.
The two sections can be adjusted to provide a length between 315mm and

Connecting the condensate drain

See
Ensure the discharge of condensate complies with any national or
local regulations in force (see HHIC recommendations).
See
Condensate drain, page 30.
1. The straight rubber coupling will accept 21.5mm (
over­flow pipe which should generally discharge internally into the
house­hold drainage system. If this is not possible, discharge into
an out­side drain is acceptable.
Important
The boiler condensate trap should be primed by pouring approxi­
mately 300ml of water into the flue spigot. Do not allow any water
to fall into the air inlet.
