STRATTON MK3 - Installation, Use and Maintenance

IMPORTANT:
The combustion product extraction duct must be dimensioned by
using the parameters set out in the table in chapter 3.3.
Depending on the actual configuration of the duct, a calculation is
required to check that the pressures at the boiler outlet at Qmin, Qall
and Qn do not exceed the maximum allowable values in this table.
Values corresponding to the 50/30°C regime are to be used for this
calculation.

The 80 Chimney Adaptor accessory has an Ø80, 500 mm long straight
component that can be cut to the desired dimension (195 mm min) .
The Ø 100, Ø 130 and Ø 150 chimney adapter have an outlet that cannot
be cut.
A purge tee is not necessary, because condensate recovery is incorporated
in the boiler. To do this use a minimum slope of 3 % towards the boiler in the
horizontal parts.
To ease fitting coat the joints with water.
IMPORTANT:
If several boilers are connected to the same flue, check the following
by calculation:
• One boiler at Qmin and the others at Qmax:: The outlet pressure
of the boiler at Qmin must be lower than the permissible pressure
specified in the table in Chapter 3.3.
• One boiler at Qall and the others at Qmax:: The outlet pressure of the
boiler at Qall must be lower than the permissible pressure specified
in the table in Chapter 3.3.
• All the boilers at Qmax:: The outlet pressure of the four boilers
must be lower than the permissible pressure specified in the table
in Chapter 3.3.
