FILLING THE INSTALLATION
The boiler may be filled by the drain tap. Filling should be
done at a slow flow rate in order to purge all the air
contained in the boiler by the upper point of the installation.
Filling is always done with circulating pumps stopped.
General
Recommendations relating to the water system are contained
in BS.5449 Pt.1, BS5401 Pt.2. and BS.6880.
MOST IMPORTANT: start up after partial or
total drain of the installation:
If all air does not purge naturally via an opened expansion
system, then in addition to automatic airvents able to ensure
continuous automatic elimination of air from the system while
it is running, the installation must also include manual
airvents so that all upper points of the installation can be
vented and so that when the installation is full of water it can
be verified that all air is eliminated before the boiler are fired.

DESLUDGING
Desludging hole
threaded 2”1/2
A desludging hole of Ø1”1/2 supplied with a plug is
provided in the lower part of the boiler to enable sludge to be
drained out. The installer can fit 1/4 turn valve.
Draining sludge involves the loss of significant quantities of
water from the system, which must be refilled after the
procedure.
Comment: Any replacement of boilers in an old system must
include a careful washing out of the full installation. Fit a
sludge trap on the return and close to the boiler.
5 CHIMNEY CONNECTION
As the Viceroy GT is a high performance boiler, the
temperature of the flue gases may be less than 160°C. The
installer ought to take all precautions (padding out, casing, T
for draining condensation) in order to avoid deterioration of
the chimney.
If necessary, the baffles of the 4 upper smoke chambers may
be partially removed with a resulting increase in temperature
of the flue gases.

DETERMINING THE FLUE
DIMENSIONAL INFORMATION NEEDED FOR CONNECTION
To size the height and cross section of the chimney, refer to
the regulations currently in force. GT boilers are boilers with
pressurised combustion chambers and the pressure of the
outlet must not exceed 0 mbar unless special precautions
are taken to seal carefully between the outlet and the flue.
The installer should provide a measuring point (Ø10mm hole)
on the flue for burner adjustment and control of the
combustion.
Detailed recommendations, relating to the design of flues for
GAS fired appliances are quoted in BS.6644 and British Gas
Publication No. IM 11., whilst BS.5410 Pt.3 similarly applies
OIL fired burners.
Chimney connection (outer Ø)
VICEROY GT 8 to 10: Ø250

Operating instructions of the Deluxe control panel
Regulation of the boiler:
The boiler is controlled either by the boiler thermostats or by
the SV-matic weather compensator (in option).
For boilers fitted with an SV-matic weather compensator the
temperature of the boiler is controlled by the action of the
regulator on the burner according to the external
temperature. The boiler thermostats will be then set to maxi.
Operating safety is ensured by the safety thermostat with
manual reset.
For boilers fitted with an SV-matic weather compensator
acting on a valve, heating temperature is adjusted by the
regulator on a motorised mixer valve according to the
outside temperature.
Regulation of domestic hot water
With SVR option or SV-matic type B:
The temperature of the domestic hot water is adjusted by a
rheostat 12 located on the SVR or SV-matic weather
compensator. When the domestic hot water is heated, the
burner and load pump start while the heating accelerator
stops; the temperature of the boiler is then regulated by the
limit thermostat incorporated in the SV-matic weather
compensator or mounted on the SVR option (this thermostat
is pre-set from factory at 80°C)
Once the hot water demand is satisfied, the burner stops
and the load pump continues to operate for 4 minutes (timing
adjustable from 30 seconds to 15 minutes). This enables the
residual calories within the body of the heater to be used,
and to complete the heating of the calorifier particularly in
summer.
Start up
Before starting the boiler, check that the installation is
properly filled with water.
Make the start up adjustments in the following chronological
order:
Put the boiler thermostats 5 to the desired position
(altering the position of the stop if necessary).
Important: For boilers fitted with an SV-matic weather
compensator adjust the boiler thermostats to max.
Put the domestic hot water thermostat 12 to the desired
temperature (SVR or SV-matic options). The temperature
of the hot water thermostat must always be lower than
the setting on the first stage boiler thermostat (or the limit
thermostat in the unique case of the SVR option).
Put switch 3:
Either on manual position : Boilers not fitted with an
SV-matic weather compensator.
Or on automatic position “AUTO”: Boilers fitted with an
SV-matic weather compensator.
Check that the safety thermostat 9 is not tripped. To do
this, unscrew the hexagonal cap and using a suitable
screwdriver, press on the reset button.
Put the burner/accelerator switch 2 on winter position
IMPORTANT: In the absence of other settings. it is advised
never to set the boiler thermostat under mark 4 (40°C) so as
to avoid all risk of condensation inside the boiler.

ASSEMBLY
Boiler
It is not advisable to drain an installation, except in case of
absolute necessity. Check regularly the water level of the
installation and top it up if necessary, avoiding a sudden inlet
of cold water into the hot boiler.
This operation can only be done a few times a year;
otherwise, look for the leakage and remedy it without delay.
Cleaning of the flue gas circuit:

Precautions to be observed in case of very long stop of the boiler
- The boiler and the chimney must be carefully swept
- Shut the boiler doors to avoid any air flow inside
- If the boiler is going to be stopped for several months, we
also advise removing the flue connection off the nozzle and
to close it with a cover
- In case of stop of the heating in winter leading to risks of
freezing, we advise the use of a concentrated antifreeze
agent to prevent the heating water from freezing.
Otherwise, completely drain the installation
