4.9.1 Important instructions for gas connection
Gas connection
– Implement the gas connection according to the technical
rules for gas installation as well as the appropriate regulations
of the country of destination and the gas supply company.
– A thermally triggered blocking device (TAE) and a gas flow
monitor (GSW) with a DVGW in
spection symbol must be fit-
ted. The TAE must comply with the test basis of DVGW-VP
301. The dimensions of the GSW must comply with the max-
i
mum adjustable rated load of the device.
Gas type
– The gas burner is factory-set to the gas type "Natural gas".
– Observe the permissible gas inlet pressure (idle pressure)
(see tab. 12-5).
4.9.2 Connecting the gas line
Ɣ Connect the factory installed corrugated gas connection hose
(A) (pipe thread DIN EN 2999 Rp ½") without tension to the
gas supply li
ne.
4.9.3 Installing/removing the burner trim
Ɣ Undo the safety screws on the upper burner trim (fig. 4-31,
item 1).
Ɣ Remove the upper burner trim.
Assemb
ly is carried out in reverse order.
Pay attention to the stipulated tightening torque
(see chapter 12.3 "Tightening torque").
DANGER OF EXPLOSION!
Escaping gas is a direct threat to human health and
safety. Even a few sparks can cause very serious ex-
plosions
.
Ɣ Before working on gas-conducting parts, always
close the gas isolat
ing valve first.
Ɣ If you can smell gas, ventilate the room thoroughly.
Prevent sparks or flames from arising (e.g. naked
flame, electrical switches or mobile phone).
Ɣ Only heating specialists au
thorised and trained by
the gas or power supply company should be
allowed to work on gas-conducting parts.
The standard corrugated gas connection hose can
cause a pressure drop of up to 5 mbar. This will not
hinder operation of the ROTEX GCU compact.
