CURRENT GAS SAFETY (INSTALLATION AND USE)
REGULATIONS OR RULES IN FORCE.
It is the law that all gas appliances are installed and serviced by a
CORGI registered installer in accordance with the above regulations.
Failure to install appliances correctly could lead to prosecution. It
is in your own interest, and that of safety, to ensure that the law is
complied with.
The Concord CXSi 110/H-180/H range of boilers has been tested
and certified by British Gas to prEN656 for use with natural gas
only.
Note. Concord CXSi 110/H - 180/H boilers are intended for use
as COMMERCIAL BOILERS and are NOT certified for use in
domestic applications. A domestic installation is defined as an
installation where the boiler takes its combustion air from a living
space or from a room directly or indirectly connected with the
living space. It is important, therefore, that no external control
devices - e.g. flue dampers, economisers etc., are directly
connected to this appliance unless covered by these Installation
and Servicing Instructions or otherwise recommended by
Caradon Ideal Limited in writing. If in doubt please enquire.
Any direct connection of a control device not approved by Caradon
Ideal Limited could invalidate the British Gas Certification, the
normal appliance warranty and could also infringe the Gas Safety
Regulations. Table 1, Table 2 and the descriptive notes which follow
contain all the essential data likely to be required by the installer.
GAS CONTROLS
The boiler lights at Low rate (approximately 70% of Full rate) by
direct burner ignition. After about 1 minute the boiler goes to High
rate and will continue at High rate until the thermostat sensor set
point is reached. The boiler will then drop to the Low rate; if the
temperature continues to rise the boiler will go Off; if the
temperature falls the boiler will revert to High rate.
ELECTRICAL CONTROLS
The boiler is supplied with 2 printed circuit boards; Board
S4561B1047 is the ignition board containing the flame-proving logic;
Board W4115A1020 contains the electronic thermostat and pump
overrun timer. A preset overheat thermostat is also provided. The
mains voltage supply is via a terminal plug in connection at the
control box. The control box displays neons indicating boiler status
as follows:
- Boiler on
- Lockout
- Overheat
An anti-cycle delay is built in to the controls to prevent rapid cycling.
