3.5.1

Planning

safety

measures

Together

with

the

relevant

authorities,

engineers

plan

the

safety

measures

that

are

required

for

simultaneous

operation

of a

ventilation

unit

and

combustion

equipment.

Alternate

operation

Alternate

operation

means

that,

when

the

combustion

equip¬

ment

is

commissioned,

the

mechanical

ventilation

system

is

switched

off

and/or

cannot

be

started.

Alternate

operation

must

be

ensured

by

appropriate

measures,

e.g.

automatically

en¬

forced

shutdown

of

the

ventilation

unit.

Simultaneous

operation

Do

not

use

differential

pressure switches

in

which

the

pressure

differential

between

the

outdoor

air

pressure

and

the

pressure

in

the

combustion

equipment

installation

room

serves

as

a

re¬

sponse

criterion.

A

fault

can

arise

from

excessively

frequent

switching.

For

simultaneous

operation

of

combustion

equipment

and

a

mechanical

ventilation

system,

we

recommend

choosing

ap¬

proved

room

sealed

combustion

equipment

(in

Germany,

with

DI

Bt

approval).

If

open

flue

combustion

equipment

is

operated

in

the

dwelling

at

the

same

time

as

a

ventilation

unit,

combustion

exhaust

gases

must

be

prevented

from

penetrating

the

home

as

a

result

of

possible

negative

pressure

in

the

room.

The

ventilation

unit

may

only

be

operated

in

combination

with

intrinsically

safe

combustion

equipment.

This

combustion

equipment

has,

for

example,

a

draught

hood

or

an

exhaust

gas

monitor

and

is

approved

for

operation

in

conjunction

with

vent¬

ilation

units.

Alternatively,

external,

tested safety

equipment

can

be

connec¬

ted

to

monitor

the

operation

of

the

combustion

equipment.

For

example,

you can

install

differential

pressure

monitoring

to

monitor

the

chimney

draught

and

to

switch

off

the

ventilation

unit

in

the

event

of a

fault.

The

equipment

for

differential

pressure

monitoring

must

fulfil

the

following

requirements:

-

Monitoring

of

the

differential

pressure

between

the

connec¬

tion

piece

to

the

chimney

and

the

room

where

the

combus¬

tion

equipment

is

installed.

-

Possibility

of

matching

the

shutdown

value

for

the

differen¬

tial

pressure

to

the

minimum

draught

requirement

for

the

combustion

equipment

-

Floating

contact

to

switch

off

the

ventilation

function

-

Option

to

connect

a

temperature

capturing

device

to

ensure

that

differential

pressure

monitoring

is

enabled

only

when

the

combustion

equipment

is

in

operation,

and

that

un¬

wanted

shutdowns

due

to

environmental

influences

are

prevented

3.5.2

Commissioning

in

buildings

with

combustion

equipment

When

commissioning

the

ventilation

unit,

it

is

important

to

check

and

document

in

the

commissioning

log

that

combustion

exhaust

gases

are

not

penetrating

the

dwelling

in

a

quantity

that

is

harmful

to

health.

Commissioning

in

Germany

Acceptance

is

carried

out by

the

local

flue

gas

inspector.

Commissioning

outside

Germany

Acceptance

must

be

carried

out

by

a

specialist.

In

case

of

doubt,

you

must

involve

an

independent

expert

in

the

acceptance

pro¬

cedure.

3.5.3

Maintenance

of

the

combustion

equipment

Regular

maintenance

of

the

combustion

equipment

is

obligat¬

ory.

Maintenance

includes

checking

the

exhaust

gas

extraction

system,

the

free

pipe

cross-sections

and

the

safety

equipment.

The

qualified

contractor

responsible

must

verify

that

there

is

a

c

sufficient

flow

of

combustion

air.

a

fan.

A

second

fan

withdraws

extract

air

from

rooms

that

are

subject

to

odours

or

moisture,

e.g.

kitchen,

bathroom,

WC.

The

extract

air

and

out¬

door

air

are routed

through

separate

air

ducts.

The

extract

air

and

outdoor

air

are

each

passed

through

a

filter.

The

extract

air

and

outdoor

air

flow

through

a

cross-countercur¬

rent

heat

exchanger.

Heat

is

recovered

from

the

extract

air

and

transferred

to

the

outdoor

air.

This

enables

a

large

proportion

of

thermal

energy

to

be

recovered.
