2.5.1 Sizing of flue
The.correct.sizing.of.the.flue.is.an.essen-
tial. condition. for. efficient. boiler. opera-
tion..
The.main.factors.to.be.taken.into.consi-
deration. for. calculating. the. section. are.
the. heat. input. of. the. boiler,. the. type. of.
fuel,. the. percentage. of. CO2,. the. mass.
flow.of.smoke.at.nominal.load,.the.tem-
perature.of.the.smoke,.the.roughness.of.
the.internal.wall,.and.the.effect.of.gravity.
on. the. draught. pressure,. which. must.
take.into.account.the.external.tempera-
ture.and.the.altitude..

ELECTRICAL
CONNECTION
The. boiler. is. supplied. with. an. electric.
cable.. Should. this. require. replacement,.

The. electric. power. supply. to. the. boiler.
must.be.230V-50Hz.single-phase.throu-
gh. a. fused. main. switch,. with. at. least. 3.
mm.spacing.between.contacts..
The. room. stat. must. be. class. II. as. spe-
cified. by. standard. EN. 60730.1. (clean.
contact).
NOTE: Device must be connected to an
