INSTALLATION
Viceroy GT Range - Installation 9
DESLUDGING
Desludging hole
threaded 2” 1/2
A desludging hole of Ø 1”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.
