1. DESCRIPTION
1.01 Introduction
RENDIMAX CE boilers are heat generators for central heating and domestic hot water production.
The standard version is designed to work with natural gas.
To use the boiler with L.P.G., on-site conversion must be carried out following the instructions given
below. This conversion must be done by our local Customer Technical Service Center.

3. INSTALLATION
Installation must be carried out by specialist companies only in accordance with all instructions and
current regulations.
You are advised to include gate valves between the boiler and the C.H. system so that the boiler can
be isolated from the system if necessary.
Notes: If the path followed by the C.H. flow outlet and return inlet pipes is such as to allow for the
formation of air pockets at certain points, you are recommended to fit an air valve at these points.
The diameter of the flue connection pipe must not be less than that of the coupling on the draft
diverter. From the draft diverter, it must have a vertical section of not less than one and a half meters.
When sizing and installing flues and the flue connecting pipe, current regulations must be respected.
If the fuel duct pass through flammable wall it has been well insulated.

Connection between boiler and chimney has to be sealed.
The rated flow rate of gas counter has to be sufficient for the whole connected appliance.
Be careful that the boilers connections are free of mechanical tensions.
Connect the gas using a rigid pipe and including a gas cock.
The boiler must be connected to a 230 Volt - 50 Hz single phase line (phase/neutral) by means of
terminal board of approved socket. A 5 A max. fuse should be included between the boiler and line.
It is important to ensure that the boiler is connected to an efficient earth system. The terminal board
for connecting the boiler to the room thermostat (if used) is inside the control panel (follow the
electrical wiring diagram fig. 3).
3.01 Electrical connection
The electrical connections has be carried out according the following electrical schema. If the boiler
is installed below the level of the C.H. system, you are recommended to install a sensor against the
water absence.
NB: The manufacturer declines all responsibility for damage to persons or things deriving from
poor earthling of the appliance.

3.02 Checking and controlling the evacuation of combustion products (total security)
The boiler is fitted with a FLUE GAS THERMOSTAT . This thermostat prevents gas from reaching the
burner if the flue is not drawing properly, providing greater security and control over the discharge of
combustion products.
If the FLUE GAS THERMOSTAT is activated, unscrew the protective cover on the control panel (Fig.
2 part. 13) and “reset” the thermostat manually. The boiler will then operate normally again.
If you replace the FLUE GAS THERMOSTAT, use original components only and make sure the electrical
connections are carried out correctly. NEVER EXCLUDE THE FLUE GAS THERMOSTAT FROM THE
ELECTRICAL CIRCUIT. If it keeps activating, contact qualified personnel only.

4. IGNITION AND SHUT-DOWN
4.01 Checks to carry out before igniting for the first time
When igniting the boiler for the first time, it is good practice to check:
- that the gate valves between the boiler and system are open;
- that the system is correctly filled and vented;
- that there are no gas or water leaks from the system or boiler;
- that the electrical connections are correct and the earth wire has been connected to an
efficient earth installation;
- that there are no inflammable liquids or materials near the boiler;
- that the flue is free from obstructions.

4.05 Temporary shut-down
To temporarily shut down the boiler, just position the main switch 6 on the “0” position.All the
electrical part remain not energized and only the pilot burner remain alight.
4.06 Prolonged shut-down
Push the button 4 (fig 6), turn clockwise the knob 1 (fig 7a) or turn the knob 1 in the position “C” (Fig.
7b). By measn this operations the gas connection to main burner and pilot is cut out. Close the gas
cock upstream from the boiler and turn off the electricity supply to the boiler.
Note: If the boiler is not used for long periods in the winter, to avoid frost damage, either add antifreeze
to the system or drain completely.
4.07 Post ignition checks and controls
On igniting the boiler for the first time:
Check there are no gas or water leaks.
Check that pilot flame is well regulated eventually it can be adjusted by means of adjustment screw
on the gas valve (fig 6 ,7a, 7b).
Check the boiler ignites properly by using the regulating thermostat to ignite and shut down the
boiler.
Check flue efficiency during boiler operation.
Check that the fuel consumption indicated on the meter corresponds to the value indicated in the
table.
Check that water circulates correctly between the boiler and system.
Check that flue connection between boiler and chimney is properly sealed.
IMPORTANT: The pilot burner inspection hatch must remain closed during normal boiler operation.
4.08 Gas consumption
The rated gas flow is shown on the technical-table at pag. 6. To get the rated gas-flow the gas pressure
has to be adjusted according the technical data sheet. Gas pressure calibration can be carried out by-
means of proper screw (fig 6,7a,7b) After the gas adjustment the consumption can be verified by
means of gas-meter after at least 5 min. operation at full output. Further small adjustment can be
carried on the gas adjustment screw (fig 6,7a,7b).
5. Gas conversion
The following adjustment and conversion operations must be carried out by qualified personnel
only. s sAs standard the boilers are calibrated for N.G.
5.01 From N.G. to L.P.G.
To convert from N.G. to L.P.G., replace the main and pilot burner nozzles then adjust main burner
pressure to ensure that nozzle pressure is as indicated for L.P.G.
Note: Nozzle diameters and main burner pressures are given in technical data tables.

Output variability with L.P.G.
5.08 Heat output variability characteristics
To adjust furnace heat input, simply regulate the main burner via the gas valve (fig. 8). This in turn
varies the heat output to the C.H. water. The diagrams in Fig. 9a and 9b show the variations in heat
output to the water in relation to variations in burner working pressure. The ability to adjust boiler
output to actual C.H. requirements means above all reducing heat dispersion and so saving fuel. In
addition, variations in output have very little effect on efficiency and combustion characteristics.

6. MAINTENANCE AND CLEANING
The following operations must be carried out by qualified personnel only.
The boiler requires no particular maintenance other than general control of boiler and chimney once
a year.Each three years the at the end of heating season boiler burner and chimney has to be cleaned.
6.01 Seasonal control of boiler and flue
Once a year before the heating season, the following controls should be carried out:
- the burner and boiler body and chimney should be clean. To clean them, you are advised to use a
soft brush or compressed air. Avoid chemical products;
- water pressure in the system (cold) should be between 0.5 and 1 bar. If not, bring it back to this
value. If the system is open vessel, check the water level in the tank.
- control and safety devices (gas valve and thermostats) should be working correctly;
- the thermocouple is free from scale and the pilot flame wraps it correctly (fig. 10)
- the pumps must not be blocked;
- the system should be free of gas or water leaks;
- gas flow rate and pressure should be in line with the values given in the table;
- the complete length of the flue gas evacuation pipe (flue and flue to boiler connection pipe)
should be clean and free from leaks.

6.03 Cleaning the boiler and burner
To clean the boiler and burner , proceed as follows:
a) turn off the gas and the electricity supply upstream of the boiler.
b) take out the boiler cover and the draft diverter cover (fig.11).
c) disconnect the electric power supply cable to the valve.
d) turn off the gas and the electricity supply upstream of the boiler.
e) remove the four screws A (fig.12) fixing the gas input pipe to the valve.
f) remove the two nuts B (fig. 12) fixing the gas assembly and combustion chamber door to the boiler.
g) remove the whole gas assembly.
Now you may clean all the smoke passages in the boiler using a pipe brush 3. Remember you should
check and if necessary clean the flue and its connection to the boiler. Be careful not to damage the
Flue gas safety thermostat phial or capillary.
Important - Do not clean the burners with chemical or a steel brush, as these might change the air-
gas mixture outlet holes. When cleaning is complete, re-assemble carefully and in the correct position.
The check the seal along the gas and smoke circuits, functioning of the control and safety devices
and gas pressure and rate of flow.
