Note.
Gas consumption is calculated using a calorific value of
38.7 MJ/m3(1038 Btu/ft3) gross or 34.9 MJ/m3 (935 Btu/ft3)
nett. To obtain the gas consumption at a different calorific
value:-
a. For l/s - divide the gross heat input (kW) by the gross
C.V. of the gas (MJ/m3)
b. For ft3/h - divide the gross heat input (Btu/h) by the gross
C.V. of the gas (Btu/ft3)
c. The appliance is preset at the factory to the highest
nominal rating.

INTRODUCTION
Mexico Super RS above range is of floor standing,
natural draught, balanced flue gas boilers. They are
range-rated to provide central heating outputs of 23.4 kW
(80,000 Btu/h) to 35.8 kW (122,000 Btu/h).
The boiler has a cast iron heat exchanger and is supplied
fully assembled, complete with a white enamelled mild
steel casing.
A door at the top of the casing front panel hinges down,
revealing the boiler thermostat control (and programmer,
if fitted).
The boilers are suitable, as standard, for connection to
open-vented systems ONLY - an overheat thermostat kit
is available to allow the boiler to be used on sealed water
systems.
The systems may be:
zpumped or gravity circulating indirect DHW only
zpumped central heating only
zpumped central heating combined with either a
pumped or gravity circulating indirect DHW circuit.
OPTIONAL EXTRA KITS
Programmer Kit Fits neatly within the casing. Separate
fitting instructions are included with this kit.
Pump Kit Fits neatly within the casing. Separate
fitting instructions are included with this kit.
Overheat is available to allow the boiler to be used
Thermostat Kit on sealed water systems.

GAS SAFETY
Gas Safety (Installation and Use) Regulations, 1994,
amendments 1996 or rules in force.
It is law that all gas appliances are installed by a CORGI
registered installer (identified by ) 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 the law is complied with.
The installation of the boiler MUST also be in accordance with
the latest I.E.E (BS 7671) Wiring Regulations, local building
regulations, bylaws of the local water authority, the Building
Regulations and Building Standards (Scotland) and any relevant
requirements of the local authority.
Detailed recommendations are contained in the following British
Standard Codes of Practice:
BS. 6891 Low pressure installation pipes.
BS. 6798 Installation of gas fired hot water boilers of rated
input not exceeding 60 kW.
BS. 5449:1 Forced circulation hot water systems (small bore
and microbore domestic central heating systems).
BS. 5546 Installation of gas hot water supplies for domestic
purposes (2nd Family Gases).
BS. 5440: 1 Flues for gas appliances of rated input not
exceeding 60 kW.
BS. 5440: 2 Ventilation for gas appliances of rated input not
exceeding 60 kW.
BS 7593 Treatment of water in Domestic Hot Water Central
Heating Systems.
Health and Safety Document No. 635.
GENERAL
The Electricity at Work Regulations, 1989.
Manufacturer’s notes must NOT be taken in any way as
overriding statutory obligations.
IMPORTANT. These appliances are certificated by the British
Standards Institution for safety and performance. It is important,
therefore, that no external control devices, e.g. flue dampers,
economisers etc., are directly connected to these appliances
unless covered by these Installation and Servicing Instructions
or otherwise recommended by Caradon Plumbing Limited in
writing. If in doubt please enquire.
Any direct connection of a control device not approved by
Caradon Plumbing Limited could invalidate the BSI
Certification and the normal appliance warranty. It could also
infringe the Gas Safety Regulations and the above regulations
or other statutory requirements.
LOCATION OF BOILER
The boiler must be installed on a flat and level floor, capable of
adequately supporting the weight of the boiler and any ancillary
equipment.
The boiler may be fitted on a combustible floor.
Insulation is not necessary, unless required by the local
authority.
The boiler must not be fitted outside.
Timber Framed Buildings
If the boiler is to be fitted in a timber framed building it should be
fitted in accordance with theInstitute of Gas Engineering
document IGE/UP/7:1998.
1. This appliance is NOT suitable for use in a direct
hot water system.
2. If the boiler is to be used on a sealed system, an
Overheat Thermostat Kit is available and must
be installed in accordance with the instructions
supplied with the kit.
