SECTION 1 INTRODUCTION

1.1 The Ravenheat boiler is for the production

of central and domestic hot water combined in one unit.

It is ﬁ tted with an automatic domestic hot

water priority valve. A Summer/winter switch is ﬁ tted to the left hand side of the control panel. With the Summer only switch position being

for domestic hot water. The summer/winter position being for

central heating with domestic hot water

priority. The boiler is equipped with a front cover

which can be removed for servicing. The

data badge with technical data is placed on

the lower part of the left hand side panel.

1.2 Fig.1 Illustrates the general layout of components. Fig.2 Illustrates the operating princi ples described in section 2.

SECTION 2

etc ,with heating circuit fully charged so as to

operate the low water sensor device the boiler

will start in the same way as domestic hot water mode . As the heating sensor reaches temperature

the fan speed modulates down. When starting, the fan will always start at the

set-point speed.

2.2.8 On the control panel are mounted two

potentiometers (thermostats) these control

the temperature. One is for domestic hot

water and the other for heating.

2.2.9 The boiler is ﬁ tted with an anti-cycling device

on the control board. This delays the boiler

from re-ﬁ ring over a 10 minute. If the heating temperature goes 20°C below the set point, the burner restarts immediately . The domestic hot water will always take

priority and is unaffected by the anti-cycling device.

GENERAL FUNCTION

2.1 DESCRIPTION OF CONTROL SYSTEM AND SEQUENCE OF OPERA TION

2.2 Domestic hot water mode

When the appliance is in rest mode with

the mains neon and switch on. Switch the summer/winter switch to Summer position, with the heating circuit

charged with water (above 1 bar). If the

domestic hot water tap is turned on,

the boiler will function in the following

sequence:

2.2.1 The pump starts. The fan starts and sends a signal back to the

ignition board that the fan is running .

2.2.2 The spark ignition system is powered which in

turn commences the spark igniter to operate

and light the burner. At this point the ignition board opens the gas

valve to light the burner.

2.2.3 When the electrode sensor senses the signal

of the burner, the spark igniter stops.

2.2.4 From the fan speed setting the boiler

increases to the maximum permissible speed

over a period of 5 seconds and will remain at

its maximum required power until its maximum

regulated temperature.

2.3 Central Heating Mode

2.3.1 A potentiometer installed on the panel

instruments permits regulation of the boiler to partial heating requirements, between maximum and minimum settings.

2.3.2 Air is drawn by the fan for combustion.

2.3.3 The fan also forces exhaust gas through the ﬂ ue

to the outside, this creates a lesser pressure in the sealed combustion chamber, thus sucking in combustion air, through the inlet duct.

2.3.4 The boiler water temperature is automatically controlled by a built in thermostat

2.3.5 Interior space temperature is set by the room thermostat to be installed in the heating system. The boiler already carries connection terminals for this thermostat, as well as for a timeclock.

The burner continues to operate until it is

stopped by the timer or one of the thermostats

2.3.6 When the internal C.H. temperature sensor intervenes the burner shuts down. The fan stops but the pump continues to operate.

2.3.7 When the room thermostats intervene the burner shuts down. The fan stops and the pump after 3 minutes turns off.

2.2.5 When the domestic hot water tap is closed the diverter valve goes back into rest mode, the burner is shut down along with the fan which is also switched off.

2.2.6 Central heating mode

2.2.7 If the switch is positioned on winter

with a demand for heat to supply radiators,

6

2.3.8 In summer position an anti-block of the pump is included. Every day the pump is powered for a period of 2 minutes. The boiler also incorporates an anti-block system which powers the pump every 24 hours, allowing it operate for 2 minutes if the boiler has not been in use. This operation may in some cases be heard for a short period when the pump has been activated.

2.4 Domestic hot water mode

2.4.1 The heat exchanger in the D.H.W. circuit is

a stainless steel plate heat exchanger water to water, and domestic water is heated by converting the water in the central heating circuit. The transference of heat is very high because the two ﬂ uids move in a counter direction ﬂ ow to each other.

2.4.2 Switch 1a Fig.50 in the winter position.

When a hot water tap is turned on a

diaphragm diverter valve excludes the central heating circuit, the boiler automatically modulates to maintain the domestic hot water at a constant temperature.

Water temperature can be regulated using

the D.H.W. thermostat located on the front control panel.

2.4.4 When D.H.W. is no longer called for the boiler automatically returns to the central heating mode.

2.4.5 Switch 1a in the Fig.50 in summer position The boiler functions like an automatic gas hot water heater When D.H.W. is no longer required the burner and fan immediately turn off.

This also takes place when switch 1a is on Winter if there is no demand for

heat to the central heating system or until the room thermostat/time clock demands for central heating circuit.

2.5 SAFETY DEVICE

In both central heating and domestic hot

water mode safe operating is ensured by a

control board shuts off the main burner if the

fan stops or the ﬂ ue or combustion air intake duct is obstructed

2.4.3 When domestic hot water is being drawn the burner and pump perform as they do during central heating except that the burner is commanded by the D.H.W. thermostat.

meter to the boiler must be of adequate size

(22 mm) min To within at least 3 metre of

the boiler (15 mm) min. can then be used for

remaining pipe work to the appliance. A smaller

size than the boiler inlet gas connection should

not be used The complete installation must be

tested for soundness as described in the above

Code N.B. if the gas supply for the boiler serves

other appliances ensure an adequate

supply is available both to the boiler and the other appliances when they are in use at the same time.

4.6.1 The terminal should be located where dispersal of combustion products is not impeded and with due regard for the damage or discolouration that might occur to building products in the vicinity (see fig. 6).

The terminal must not be located in a place

where it is likely to cause a nuisance In cold and/or humid weather water vapour may condense on leaving the flue terminal.

The effect of such steaming must be

considered

The terminal must not be closer than 25 mm (1 in) to any combustible material For protection

of combustibles, refer to BS 5440.1.

Where a flue terminal is installed less than

1000 mm. from a plastic, or painted gutter; or 500 mm from painted eaves, an aluminium shield 1000 mm. long, should be fitted to the underside of the gutter or painted surface.

Pluming will occur at the terminal so, where

possible, terminal positions which could cause a nuisance should be avoided.

The flue must be installed in accordance with

the recommendations of BS 5440: Part 1.

IMPORTANT NOTES For greater ﬂ ue lengths see alternative ﬂ ue instructions. Flue must be positioned in a place not likely to cause a nuisance from pluming.

IMPORTANT NOTICE: If the ﬂ ue terminates

less a balcony, above the ground, or above a ﬂ at roof to which people have access, then a suitable terminal guard must be ﬁ tted. 0001PRO06005/0 Fit only recommended FLUE TERMINAL GUARD by securing concentrically around terminal with screws. Available on request from:

IMPORTANT: The following notes are intended

for general guidance The boiler MUST be installed so that the terminal is exposed to external air.

It is important that the position of the terminal allows the free passage of air across it at all tirnes.

Minimum acceptable spacing from the terminal to obstructions and ventnation opening are speciﬁ ed in Fig. 6.

Note positions: Due to the terminal design, installation is possible with clearances less than those speciﬁ ed in BS 5440, Part 1

NOTE: The flue must be terminated in a place not

likely to cause a nuisance.

4.6.2 A concentric vertical flue kit is available for flueing applications up to a maximum height of 4 metres.

For further details see vertical flue installation

instructions.

4.7 AIR SUPPLY

4.7.1 The following notes are intended for general

guidance.

The room sealed fan flued boiler does not

require a permanent air vent for combustion air supply.

Where installed in a cupboard or compartment

ventilation is not required.

4.8 WATER CIRCULATION (central heating)

4.8.1 Detailed recommendations are given in

BS 6798:1987/5449:1990 (for smallbore and microbore central heating systems). The following notes are given for general guidance.

4.8.2 Pipework

Copper tubing to BS 2871 1.1.1971 is

recommended for water pipes. Jointing should be either with capillary soldered or with compression fittings.

Where possible pipes should have a gradient

to ensure air is carried naturally to air release points and water flows naturally to drain taps. It should be ensured as far as possible that the appliance heat exchanger is not a natural collecting point for air except where providing useful heat, pipes should be insulated to prevent heat loss and to avoid freezing. Particular attention should be paid to pipes passing through ventilated spaces in roofs and under floors.

4.8.3 The water through the appliance heat exchanger circuit must exceed the min. 2.38 gals/min. (650 It/h) when the burner is firing. It is important to ensure that this rate is achieved when sections of the system are shut off either manually or by automatic controls.

Therefore a by-pass must be fitted to the

system (15 mm min.) (Fig. 6A).

If the volume of circulating water is too low, the

boiler water temperature will rise too rapidly. This could cause noise in the system or even cause the safety thermostat to trip.

14

Fig.6A

4.8.4 Draining tap These must be located in accessible positions

to permit the draining of the whole system. The taps must be at least 15 mm nominal size and manufactured in accordance with BS 2870

1980.

4.8.5 Air release points These must be fitted at all high points where

air will naturally collect, and must be sited to facilitate complete filling of the system.

4.8.6 The appliance has an integral sealed expansion vessel to accommodate the increase of water volume when the system is heated.

It can accept up to 6 Its of expansion water.

If the appliance is connected to a system with an unusually high water content, calculate the total expansion and add additional sealed expansion capacity as appropriate (Fig. 7). In general, modern systems will present no problem.

4.8.8 Permissible methods of filling

Fig.7

4.8.7 Mains water feed: central heating There must be no direct connection to the

mains water supply, even through a nonreturn valve, without the approval of the Local Water Authority.

5.5 INSTALLING THE APPLIANCE FOR

REAR FLUE OUTLET (Fig.28-30-31-32)

5.5.1 Use adhesive tape to attach the template to

the wall, making sure that the centre line is vertical.

- Mark the two holes for to fix the hanging

bracket on the wall as well as the centre

of the flue duct.

- Detach the template from the wall.

- Use a 10 mm. dia drill to make the 2 holes.

Insert the plastic expansion plugs.

- Cut or core drill a 105 mm. dia hole for inserting the flue duct.

- Locate the wall hanging braket and fix by the two coach bolts Fit the elbow header positioning it towards the required direction (Fig 28).

5.5.2 Make sure that the rubber Ø 60 is locate into

the flue elbow header .

5.5.3 If using horizontal flue duct and it is too long

it can be shortened . Shoud it be necessary to cut the flue, always cut equal amounts from both inner and outer pipes. Always cut the end furthest from the terminal. cut end must de-burred. NOTE : Add 30mm to overall flue length to allow for cover plate. (Fig.12 - item 127)

5.5.4 Insert the flue assembly into the wall, being careful to make sure that the outer air duct comes flush to the inner surface of the wall.

5.5.5 Lift the boiler on to the wall (Fig.28), locating onto the fixing jig wall bracket.

5.5.6 Working above the boiler pull the flue exhaust duct towards the boiler in order to engage tube 61 into its header.

Position flue into elbow header and push so as

to locate inner and outer flue correctly ensuring good seal is made with o rings.

5.5.7 Fit terminal cover plate and if necessary terminal guard.

5.5.8 Extensions kits are available to order for flue extension of up to 7 metres total length.(Fig.31A).

5.5.9 Each extension length extends the pipe by approximately 1000 mm long up to a maximum of seven extensions

Pipeline length can be established using the

instructions in section 5.5 for rear flue outlets and section 5.7 for side flue outlets. Extensions must be installed with the widened end of the air intake pipe and the tapered end of the flue pipe aimed towards the exhaust terminal.

Fig 28

Extensions must be installed with the widened

end of the air intake pipe and the tapered end of the flue pipe aimed towards the exhaust terminal. Extensions must be joined together with the standard terminal pipe, and inserted in each other as far as they can go.

If an extension must be shortened, this must

be done from the straight end, and not from the widened or tapered end. To measure the pipeline properly all components must be assembled and total length measured before cutting. The straight end of the extension connects to the boiler. The flue output and air intake pipes fits into the boiler header until it stops. (Fig. 31- Fig. 31A).

When cutting both inner and outer ducts of the

extension, always ensure that the reduced end (male) of the inner and outer duct are square and

to the same length. All joints must be sealed with the rubber seals supplied. It is important to put the centering spacer,

supplied with the unit, inside between the two

pipes, from the side opposite the extension’s

straight end. NOTE: a suitable support bracket is available

from Ravenheat Manufacturing and should be

used to support flue length at least every 1.8

metre preferably at each joint this bracket should

be secured to wall and flue duct.

19

5.5.10 IN LINE FLUE BEND Measure the distance between the flue bends or

the flue/terminal assembly. The measurements should be taken from the outer edge of the flue and bend (Fig. 39B).

IMPORTANT: inline flue bend - 1000 mm

must be deducted from overall length for each 90°bend. Obtuse flue bend - 500 mm must be deducted from overall length for each 135° bend (Table 6).

Insert the Vertical Flue terminal assembly through the flashing plate from the outside. Fix the appliance to the wall, locating onto the Wall fixing bracket. Measure the vertical distance between the top of the flue (Fig. 42a) and the bottom of the flue terminal assembly (Fig. 41). The measurements should be taken from the outer diameter of the flue. NOTE: Where this length does not match any standard combination of the extensions, extension can be cut to the required length (Fig. 44). When cutting both inner and outer ducts of the extension, always cut on spigot side, and they must be de-burred.

Starting at the appliance end, assemble the extension duct sections, making each inner and outer (flue) joint by inserting the spigot end into the socket end of the next tube, making sure the seal rings are correctly located (Fig. 44). Make sure that the entire flue is adequately supported. Use at least one bracket for each extension used. Ensure that all inner flue connections have a good fit/seal, and that the space clips in each extension are correctly positioned.

- Position the flue extension and fix the securing screw on the flue adaptor on the appliance

(Fig. 43) item 66, and ensure that the gasket is

correctly fitted.

- Pipe dimensions and positions are marked on template supplied and fig. 49a.

5.11 DOMESTIC HOT WATER (Fig. 46)

5.11.1 The domestic hot water circuit does not need

a safety valve but it is essential to ensure that the pressure of the cold water supply does not exceed 10 bar. If in doubt it is advisable to install a pressure reducing valve The minimum pressure needed to operate the domestic hot water system is 0.5 bar with a flow of approx 3 Lts per min. Flush out all foreign matter from the supply pipe before connecting to the appliance.

- Connect the 15 mm. cold water pipe to the stop cock to the appliance inlet.

- Connect the 15 mm. hot water pipe to the cock to the appliance inlet.

5.12 SAFETY VALVE DISCHARGE

5.13.1 IMPORTANT: Electricity supply must be as

specified in clause (sect. 4.10)

- When controls external to the appliance are required, design of the external electrical circuits should be undertaken by a competent person. In accordance

with the IEE wiring regulations.

It is essential that all external controls

MUST VOLT FREE.

Factory fitted internal wiring must not be disturbed when wiring external controls.

- To gain access to the electrical box remove the front panel of the case as described in clauses sect. 8.1.4 (Fig.54),

remove the two securing screws on the supporting bracket and lower down , unclip the four plastic tabs and lift off the electrical box cover (Fig.65).

- The terminals are easily visible on the front of the electronic control board (Fig. 48).

- Heat resistant flexible cable is fitted between the isolator and the terminal block

2

A 3 core cable of 0.75 mm

(24x0,2 mm) to BS 6500. Make sure all wires to the appliance are routed away from sharp edges and hot surfaces.

The cable must be fastened with its cord anchorage and connected so that should the cable slip from the anchorage the current carrying conductors become taut before the earthing conductor. Securely tighten all terminal screws and arrange the cable with slack between the cord anchorage and the terminal block

WARNING: If the supply cord is damaged, it must be replaced by a service engineer (supply cord available from Ravenheat Manufacturing Ltd).

5.15 CONDENSATE DRAIN CONNECTION

5.15.1 The condensate drain connection is between

Gas service cock and Central Heating Flow valve connections (Fig.49A). An 25mm

plastic overflow pipe is fitted on the

condensing trap and must should be used to fit on the drain connection, if required, to discharge condensate to a drain. The drain pipe should have a fall of a least 2.5° away from the boiler. Condensate should, if possible be discharged into the household internal drainage system.

POSITION OF WATER AND GAS CONNECTIONS

Fig. 49A

If this is not practicable, discharge can be

allowed into the external household drains or a purpose designed soak away.

It is recommended that any external

condensate drain pipe is insulated and also preferably of 32 mm diameter, to prevent

freelzing in adverse weather conditions. The condensate is discharged periodically in “ slugs” by siphonic action. It is not

necessary to provide air breaks or extra

traps in discharge pipe as there is already a

125mm high trap inside the boiler. Fitting an extra trap may cause the boiler

siphon to work incorrectly. Refer to BS5546 or BS6798 for advice on

disposal of boiler condensate.

Once the process of commissioning the boiler is complete, the commissioning engineer MUST complete his section in the Benchmark log book.

6.10 CHECKING THE FLUE SYSTEM

6.10.1 The flue system should be visually checked for

soundness Check all connections and fixings are secure and tight

6.11 CHECKING THE HEATING THERMISTOR

6.11.1 Allow the system to warm up and then turn

the C.H thermistor to ensure the main burner modulates from “high” to “low” and “low” to “off” and vice versa (scale range

covers approx. 45° C / 85° C).

6.12 TESTING AND REGULATING THE DOMESTIC HOT WATER SYSTEM FLOW

6.12.1 Put the appliance in summer position with

the (summer/winter) switch (Fig.50).

- Open a domestic hot water tap (preferably

the bath tap). Ensure cold water inlet stopcock is open and the D.H.W. control knob (Fig.50) is set at maximum.

- Digital display show water temperature in demand ( led on)

- If the boiler does not light check that the water flow rate is above the min. required to operate the differential pressure 2 8 Lts./ min. (0.61 gals/min).

- The temperature of the water will depend on the rate at which it flows. If, due to high water pressure, the flow rate is too high (and thus the temperature too low for practical use) the flow rate may be adjusted. It is better to set for the lowest acceptable temperature,

preferably at the bath tap since the user can gain higher temperatures at other

restricted flow taps (Table ...)

-If the cold supply is subject to large fluctuations or is above the permitted max. water pressure, a suitable pressure/flow regulator should be fitted in the cold water supply to the appliance.

- Slowly close the draw off tap to reduce the flow rate to above the min

(approx. 2.8 litre/min)

- 0.61 gals/min.). Rotate the D.H.W. control knob to ensure it operates at its various setting.

- Close the draw-off tap still further. The burner should stop when the rate falls below about 2.8 litres/min (0.61 gals/min ).

6.13 HANDING OVER TO THE USER

6.13.1 After completion of installation and

commissioning of the system, the installer should hand over to the Householder by taking the following actions:

- Hand the “User’s Instructions” to the Householder and explain His/Her responsibilities under the “Gas Safety Regulations 2000”.

- Explain and demonstrate the lighting and

shutting down procedures.

- The operation of the boiler including

the use and adjustment of ALL system controls which should be fully explained to the Householder. This then ensures the greatest possible fuel economy consistent with household requirements of both heating and hot water consumptions.

Advise the User of the precautions

necessary to prevent damage to the system, and to the building, in the event of the system remaining inoperative during frost conditions

-

Explain the function and the use of the

boiler switch Summer/Winter and ON/OFF switch,reset and digit display .

- Explain and demonstrate the function of

temperature controls, neon lights radiator valves etc for the economic use of the system.

- If an optional time clock is fitted, then

draw attention to the time clock User’s Instructions and hand them to the Householder

- Stress importance of regular servicing by

a qualified Heating Engineer and that a comprehensive service should be carried out AT LEAST ONCE A YEAR

- Fill in the Benchmark log book and leave

completed with the customer.

IMPORTANT :Please, lubricate the internal part of the seals before being fitted.

IMPORTANT These instructions must be read in

conjunction with the main installation and servicing instructions As with all ﬂ ues the kits must be installed taking due account of the current issue of BS 5440 parts 1 & 2 and timber frame housing REF DM2 Also note that the requirements will vary depending upon the kit being installed. Guidance is provided but unless otherwise stated, always comply with the recommendations of the relevant codes of practice

ﬂ ue eccentric ﬂ ue duct systems only When ordering twin ﬂ ue it must be stated for CSI LOW NOX range. Typical installation procedures are illustrated by drawings

Before ﬁ xing the twin ﬂ ue system the existing Remove the front panel of the case(sect.8.1) Unscrew the screw (Fig.31 item 66) on the Flue adapter.

Make sure that the Flue manifold rubber seal is locate into the ﬂ ue manifold, and lubricate the internal part of the seal before assembly. (see sect. 4.6) Locate the header gasket on the twin ﬂ ue header and push into the Flue adaptor (Fig.31 item 56) making sure that the inner plastic exhaust locates ﬁ rmly in the outlet spigot of the ﬂ ue manifold, and screw the securing screw that secure the twin ﬂ ue

header on the boiler. Locate the 2 x 80 mm ‘O’ rings in the twin flue header and lubricate the internal part of the seal before assembly to ensure easy snug ﬁ t.(see sect. 4.6)

Figures show the versatility of this flueing

system. Measurements and bends must be

calculated correctly so as not to oversize

maximum flue lengths.

All located ‘O’ rings must be lubricated with

a silicone grease to ensure easy, snug fit.

NOTE: Exhaust flue must slope 2.5° down

towards the boiler 45 mm/m fall per metre of

flue length.

Spacing Clips

Spacing Clips are available on request should

they be required.

NOTE: for eccentric vertical flue a 125 mm

(5 in) diameter flashing plate will be required.

IMPORTANT:

- See Fig. 6 and 42 for terminal clearances.

- The pressure loss see table 6.

IMPORTANT NOTICE:

- inlet and exhaust terminals must never be installed on opposite walls of the building (PrEN 483).

- If the ﬂ ue terminates less than 2 m above a balcony, above

the ground, or above a ﬂ at roof to which people have access, then a suitable terminal guard must be ﬁ tted.

- Fit only recommended ﬂ ue terminal guard by securing concentrically around terminal with screws.
