are ready to be commissioned, remove the
protective plastic film from the casing panels.
Fitting the Inserts
The Isis HE boiler utilises steel insert tubes in the flue
way passes to extend the effective heat exchanger
surface area thus increasing the operating efficiency.
WARNING THESE
INSTALLED BEFORE THE BURNER IS FIRED
OTHERWISE DAMAGE MAY OCCUR TO THE
FLUE SYSTEM DUE TO HIGH EXHAUST GAS
TEMPERATURES.
1. The insert dimensions vary depending on the
boiler size and the dimensions of the tubes to be
fitted should be checked against the sizes given
in the Parts List prior to fitting to ensure the
correct inserts are installed.
2. The inserts should be installed with the pointed
end, incorporating the removal ring, pointing
towards the front of the boiler and must be
pushed fully back as shown in Fig.18.
IMPORTANT: If the inserts are not correctly installed
damage to the insert may occur.
3. The inserts should be positioned to ensure that
they sit on the support feet as detailed in Fig.19.

Insert Removal
The inserts should be removed using the insert
removal tool provided by hooking the insert removal
ring and withdrawing.
Boiler Tool Storage
Following completion of boiler assembly, the cleaning
tools, insert removal tool and door access socket and
"T" bar should be left in a safe and secure position
within the boiler room. It is recommended that a tool
rack is incorporated within the boiler house for this
purpose.
Fitting the Burner
1. Check that the burner which has been supplied is
the correct type for the boiler.
2. Fit the burner adaptor plates and boiler gasket to
flue
the boiler using the M12 countersunk fixing
screws.
3. Place the burner gasket over the burner fixing
studs.
4. Insert the burner draught tube into the firing door
aperture with the gasket in position on the
mounting flange. Secure in position with the nuts
and washers provided.
5. Prepare the "Cafco Blaze" insulating compound
as detailed below and pack it between the
draught tube and the firing door refractory. It is
essential that the whole gap is filled and that the
compound be compressed and finished flush with
the inner face of the door refractory lining.

6. Connect the fuel supply to the burner. The fuel
supply pipes should be self-supporting and not
apply undue pressure on the burner.
7. Connect the sight glass cooling tube. One end
joins the burner body, the other end with the sight
glass nipple.
IMPORTANT: Failure to connect the cooling tube
can cause damage to the boiler if operated.
8. Connect the burner cable and plug to the
Amphenol socket on the control panel.
9. Check the weight of the burner has not affected
the sealing of the door to the front section,
especially after the door has been opened and
closed several times.
Larger burners, especially dual fuel types, should
be supported independently with a suitable
device whilst still allowing the door to be opened.
