• Connect the appliance to the gas supply
connection with the DVGW approved
connection hose, which features a
cross-section suitable for the given
rated power and length.
• Gas connection (a) is located at the
back of the appliance.
Fig. 2
• Make sure that the gas connection hose does not run on or near hot surfaces, is
not subject to stress or pressure and does not come into contact with sharp
edges or other objects that could damage the hose.
• After connecting the appliance, all connection points between the installation
and the appliance must be subject of tightness check. To this end, use spray for
detecting leakages or foam producing agents, which do not spur corrosion.
Connection points should be covered with an agent
— no air bubbles should be
produced. Also the gas shut-off valves should be subject of this check.
NOTE!
Do not use open fire to test tightness!
Checking Gas Pressure and Rated Heat Load
• With first installation, the gas installation technician must check nominal heat
load of the appliance, as we as perform maintenance.
• DO NOT attempt to increase the power nor rated heat load specified by the
manufacturer.
• Check the rated heat pressure with gas meter and a stop watch. Measure
exactly the amount of gas flowing per unit of time the appliance is consuming
with maximum power.
• Compare the measured value with data on consumption in section
'Technical
Specifications'
, Table 3. Admissible deviation is ±5%.
