INTRODUCTION
The Ravenheat boiler is for the production
of central and domestic hot water combined
in one unit.
It is fitted with an automatic domestic hot
water priority valve.
A Summer/winter switch is fitted 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.
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 fitted with an anti-cycling device
on the control board. This delays the boiler
from re-firing 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.
Fig.1 Illustrates the general layout of
components.
Fig.2 Illustrates the operating principles described in section 2.
GENERAL FUNCTION
SECTION 2
2.1
DESCRIPTION OF CONTROL SYSTEM
AND SEQUENCE OF OPERATION
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:
The pump starts.
The fan starts and sends a signal back to the
ignition board that the fan is running .
2.2.1
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.
2.2.5
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,
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 flue
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.
2.3.8
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 fluids move in a counter
direction flow 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.
2.4.4
2.4.5
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 flue or combustion air intake
duct is obstructed
2.5.1
An overheat cut off thermostat acts to
turn of the burner to resetable “lockout”
(Fig. 50) .
A safety valve is fitted on the central heating
circuit set at 3 bar.
A low water pressure switch set at 0.4 bar is
fitted on heating circuit.
Water temperature can be regulated using
the D.H.W. thermostat located on the front
control panel.
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.
OVERALL DIMENSION
Fig.3
AVAILABLE PUMP HEAD
Fig.4
When D.H.W. is no longer called for the boiler
automatically returns to the central heating
mode.
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.

obligations.
GENERAL REQUIREMENTS
SAFETY
Gas Safety (Installation and Use)
Regulations, 1994 and amended 2000.
It is law that all gas appliances are installed
and serviced by a CORGI registered installer
in accordance with the above regulations
and these installation instructions. All CORGI
registered installers carry a CORGI I.D. card
and have a registration number. Both should
be recorded in your boiler log book. You can
check your installer by calling CORGI direct
on: 01256 732300. 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. Check the boiler
and flue is the correct type for installation.
The installation of the boiler MUST be
in accordance with the latest I.E.E. (BS
7671) Wiring Regulations, local building
regulations, bye-laws of the local water
authority, the building regulations and the
Building Standards (Scotland) and any
relevant requirements of the local authority.
GENERAL INFORMATION

GAS SUPPLY
4.5.1
A gas meter is connected to the service pipe
by the Local Gas Region or the Local Gas
Region contractor. An existing meter should
be checked preferably by the Gas Region to
ensure that the meter is adequate to deal with
the rate of gas supply required for all appliances
it serves. Installation pipes should be fitted in
accordance with BS 6891. Pipework from the
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.
FLUE SYSTEM
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 flue lengths see alternative flue
instructions. Flue must be positioned in a
place not likely to cause a nuisance from
pluming.
IMPORTANT NOTICE: If the flue terminates
less a balcony, above the ground, or above

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.

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.

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.

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.

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.
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.

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

Typical installation procedures are illustrated
by drawings
Before fixing the twin flue 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 flue manifold, and lubricate
the internal part of the seal before assembly.
(see sect. 4.6)
Locate the header gasket on the twin flue
header and push into the Flue adaptor
(Fig.31 item 56) making sure that the inner
plastic exhaust locates firmly in the outlet
spigot of the flue manifold, and screw
the securing screw that secure the twin flue
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 fit.(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.
