Venting
Boiler breeching and main chimney
De Dietrich GT Series boilers are a high performance
boiler. The ue gas temperature can be less than 320°F
[160°C]. Special attention is required for the venting
of the boiler according to the specic site operating
conditions.
WARNING
The De Dietrich boiler can be operated at low ue
gas temperatures. As a result ue gas condensation
may occur and could accumulate in the breeching
and main chimney. Suitable provision for ue gas
condensation draining is required. A condensate TEE
tting shall be provided on the main chimney as close
as possible to the boiler breeching collar (See g
8553N143). Any horizontal portion of the breeching
shall be kept to minimum.
A vent category chart has been provided to further
assist the heating specialist to determine and evaluate
whether the correct venting is applied for each gas vent
category.
