2. SAFETY WARNING This analyser extracts combustion gases that may be toxic in relatively low concentrations. These gases are exhausted from the side of the instrument. This instrument must only be used in well ventilated locations. It must only be used by trained and competent persons after due consideration of all the potential hazards.
4. NORMAL START UP SEQUENCE 4.1 Every Time You Use The Analyser BEFORE SWITCH-ON CHECK THAT: the particle filter is not dirty the water trap and probe line are empty of water all hose connections, etc, are properly made the probe is sampling CLEAN AMBIENT air the water trap is correctly fitted and the instrument upright the flue temperature is connected Switch ON the instrument by pressing 4.
Once the time has reached zero an audible beep will be heard and will show the selected fuel on the following display:NATURAL GAS ∗PRESS -MENU- KEY∗ Press This zeros the toxic sensor and sets Oxygen to 20.9%. The next screen is the MAIN DISPLAY of the analyser:- NETT C O2 % CO ppm EFF (G) % Use and 0.0 20.9 0000 0.0 to change the display.

4.3 Main Displays The main display can be changed to show either 4 or 8 parameters at one time. Two options are available when 4 parameters are selected. • 4 Page Mode displays 4 lines of data in set format, each page is predefined. • Line scroll mode allows you to customise the display to show the data you require. • 8 Page Mode displays 8 parameters on 4 lines in set format, the bottom two can be changed. Changing between the different modes is detailed in Display Menu Section 5.2.4. 4.3.
4.3.2 Line Scroll Mode Line scroll mode allows you to customise the display. Use the and keys to change the bottom line of the display. Once the correct line is displayed press to confirm and move the line up. Select the next parameter and repeat until all lines display the desired parameters. Change bottom line using and to select and move parameter up Select next parameter. Repeat above until display reads desired data NETT O2 CO CO2 C % ppm % 0.0 20.9 0000 0.0 O2 CO CO2 CO2 % . . . 20.9 ppm .
4.4 Sampling the Flue Gas Once the automatic calibration procedure has been completed and the specific fuel has been selected (See SELECT menu) the probe can be inserted into the desired sampling point. It is recommended that the sampling point be located at least two flue diameters downstream of any bend and that the probe tip is in the centre of the flue. With balanced flues and other domestic units the probe should be positioned far enough into the flue so that no air can ‘back flush’ into the probe.
4.6 Regular Checks During Sampling Care must be taken at all times not to exceed the analysers operating specifications, in particular ensure the following :• Do not exceed the maximum temperature of the flue probe. • The analyser internal temperature does not exceed normal operating range, typically 0-50°C. • DO NOT PLACE THE INSTRUMENT ON A HOT SURFACE. • The water trap is vertical at all times. Water condenses in the probe line and can quickly fill the water trap when the probe is moved.
4.8 Electromagnetic Compatibility The European Council Directive 89/336/EEC requires that electronic equipment does not generate electromagnetic disturbances that exceed defined levels and has an adequate level of immunity to enable it to be operated as intended. The specific standards applicable to this product are detailed in the appendices.

6. PRINTING INFORMATION Supplied as accessories for the KANE900 Plus are an infra-red thermal printer or a dot matrix serial printer. Read the manual supplied with each printer prior to operation. Connections to the KANE900 Plus are detailed below : • Infra-red thermal printer - this does not require a cable to transmit the data but uses an infra-red (IR) link similar to a TV remote control. The IR emitter is positioned on the top of the KANE900 Plus and the bottom of the printer.

When you are ready to store the first reading, go into the STORE menu, use the and has been stored. to find the “Ave Store” item. Press . The first sample The screen appears to go back to the main screen but there is a tiny difference: the right-most column has just one ‘+’ there. The line that it is on tells you which sample and keys, you can you have got to in the obvious way.
Get into the average of three viewing mode, “Ave View” as above. Offer a printer to the instrument in the usual way. Press flagged as NOT FITTED. KANE900 Plus Operators Manual .
9. MAINTENANCE 9.1 Emptying and Cleaning the In-line Water Trap The in-line water trap should be checked and emptied on a regular basis. Water vapour will condense and gather in the probe line. This may move suddenly to the trap when the probe is moved. Care should be taken at all times. Emptying of the water trap is detailed below :- Carefully remove the end cap from the in-line housing. Dispose of the condensate in a suitable drain, care must be taken as it could be acidic.
10. PROBLEM SOLVING The following is a list of problems that may occur on the instrument through its operating life. If the cause of the fault is not easy to identify then we advise you contact Kane International Service Department or an International Distributor for expert advice.

APPENDICES A - Main Display Parameters The parameters and their meanings are detailed as follows : DATE : Analyser date. See Set-Up menu section 5.2.5 to change. TIME : Analyser time. Use Set-Up menu section 5.2.5 to change. BATTERY : (BAT) Displays the battery level from 0-100%. The analyser will flash RECHARGE BATTERY at less than 10 % of charge. With the charger connected the display shows AC ON.
AMBIENT : (Ta) Temperature measured by the internal sensor, used in the NET temperature calculation if an INLET probe is not fitted. CO/CO2 R : The CO/CO2 ratio, is the ratio of measured CO divided by calculated CO2. It gives an indication of the following :• • How good a gas sample the instrument is reading. How clean the boiler is running. For example : A new or clean domestic boiler will display a ratio of less than 0.004, a unit in need of cleaning 0.004-0.
B. COMBUSTION EFFICIENCY CALCULATION The efficiency calculation is based upon British Standard BS845.
Calculated data: Tnet Tnet = Net Temperature % CO2 content in flue gas % Dry Flue Gas losses % Wet losses % Unburned carbon loss % Efficiency = Flue Temperature - Inlet Temperature Dry flue gas loss % = 20.9 x K1 x (Tnet) / K2 x (20.9 - O2m) Wet loss % = 9 x H2 + H2O / Qgr x [2488 + 2.1Tf - 4.2 Ti] simplified = [(9 x H2 + H2O) / Qgr] x 2425 x [1 + 0.001 Tnet] Wet loss % = K3(1+0.001xTnet) Where K3 = [(9 x H2 + H2O) / Qgr] x 2425 Net Efficiency % = 100 - dry flue gas losses = 100 - 20.
C. CALCULATION OF FUEL DATA For any fuel not specified by Kane International the net calorific value, gross calorific value and composition should be obtained from the fuel supplier. The following fuel data has been calculated with reference to the efficiency calculation. Example 1: Chemical composition: C H2 H2O Qnet Qg Max CO2 25% 3% 50% 8.35 MJ/kg 9.3 MJ/kg 20.4% K1n = (255 x % carbon in fuel) / Qnet (kJ/Kg) = (255 x 25) / 8350 = 0.
D. ELECTROMAGNETIC COMPATABILITY (CE) STATEMENT This product has been tested for compliance with the following generic standards: EN 61000-6-3 EN 61000-6-1 and is certified to be compliant Specification EC/EMC/KI/KANE900 Plus details the specific test configuration, performance and conditions of use. Please Note: Batteries used in this instrument should be disposed of in accordance with current legislation and local guidelines.
