1 Introduction
1.1 About the appliance This manual describes how to install, service and use an SCE-appliance. An
SCE appliance is a gas-fired open waterheater without a fan. The SCE
appliance is fitted with flue gas outlet protection and falls into the appliance
category B11BS. You can find this information on the appliance's identification
plate. The information in this manual applies in respect of types SCE: 80-115,
80-140, 80-180, 95-199, 95-260, 70-360, 65-400, 65-500.
The construction and fittings for the appliance comply with the European
standard for gas-fired storage water heaters for sanitary use (EN 89). The
appliances thus comply with the European Directive on Gas Appliances and are
therefore authorised to bear the CE mark.
Warning
Read this manual carefully before putting the waterheater into operation.
Failure to read the manual and to follow the specified instructions may lead
to personal accidents and damage occurring to the appliance.
1.2 What to do in the
case of gas smell Warning
For gas smell:
No naked flames! No smoking!
Avoid sparking! Do not use any electrical switches, so no telephones, plugs
or bells!
Close the main gas supply!
Open windows and doors!
Warn residents and leave the building!
After leaving the building, warn the gas distribution company or installer.
1.3 Regulations As the (end) user, installer or service and maintenance engineer, as a minimum
requirement you should ensure that the complete installation complies with the
local, valid:
• regulations governing building regulations;
• directives for existing gas installations drawn up by your power supplier;
• directives for natural gas installations and the associated practical
guidelines;
• safety requirements for low-voltage installations;
• regulations governing the supply of drinking water;
• regulations governing ventilation in buildings;
• regulations governing the supply of combustion air;
• regulations governing the discharge of flue gases;
• requirements in respect of installations consuming gas;
• regulations governing internal sewage inside buildings;
• regulations governing fire brigade, power companies and the municipality;

10 Instruction Manual SCE
1gis
What is more the installation should comply with the manufacturer's regulations.
nRemark
Supplements or subsequent changes and/or additions at the time of
installation shall apply in respect of all regulations, requirements and
guidelines.
1.4 Target groups The three target groups for this manual are:
• (end) users;
•installers;
• service and maintenance engineers
Symbols are shown on each page indicating for which target groups the
information is intended. See Ta ble 1.1 .
1.5 Maintenance A service should be carried out a minimum of once a year both on the water side
and on the gas side. Maintenance frequency depends, amongst other things, on
the water quality, the average burning time per day and the set water
temperature.
nRemark
To determine what the correct maintenance frequency is, it is recommended
to get the service and maintenance engineer to check the appliance on the
water and gas side three months after installation. The maintenance
frequency can be ascertained on the basis of this check.
nRemark
Regular maintenance extends the service life of the appliance.
Both the end user and the service and maintenance engineer are responsible
for regular maintenance. They will need to establish clear agreements on this.
nRemark
If the appliance is not regularly maintained, the warranty will be void.
