INSTALLATION
INST
ALLA
TION
26 FITTING THE CASING
1.
Check that the sealing strip is
in place along the four rear
edges of the boiler casing.
2.
Lift the boiler casing up to the
boiler assembly, locate over
the upper support bracket and
secure with the 3 captive
screws.
3.
The casing must be sealed
correctly. This MUST be
checked by ensuring that, at
the top and bottom edges of the
casing, the seal is compressed
over its complete length.
After completing the installation and commissioning of
the system the installer should hand over to the
householder by the following actions:
1.
Hand the User's Instructions to the householder and explain
his or her responsibilities under the Gas Safety (Installation
and Use) Regulations 1994, amendments 1996 or rules in
force.
2. Deluxe Model (LX)
- Draw attention to the lighting instruction
label affixed to the controls casing bottom panel.
Standard Model
- Draw attention to the lighting instruction
label affixed to the controls pod door.
3.
Explain and demonstrate the lighting and shutting down
procedures.
4.
The operation of the boiler and the use and adjustment of
ALL system controls should be fully explained to the
Householder, to ensure the greatest possible fuel economy,
consistent with household requirements of both heating and
hot water consumption.
28 HANDING OVER
WARNING.
The boiler MUST NOT be operated with the casing removed.
Make the following checks for correct operation:
1.
Turn the boiler thermostat OFF and ON and check that the
main burner is extinguished and relit in response.
2. Flame failure device
Check the operation of the flame failure device in the gas
control valve, as follows:
a.
Extinguish the pilot flame by closing the gas service
cock (H) and note the time taken for the flame failure
device to shut down - identified by a click within the gas
control valve.
b.
Open the gas service cock and relight the pilot.
3.
With the burner alight again, turn the gas control knob
clockwise until resistance is felt and then release it. The
burner and pilot flame should shut down immediately.
Note.
A latch in the gas control provides a safety delay
period before the pilot can be relit.
4.
The correct operation of ANY programmer and all other
system controls should be proved. Operate each control
separately and check that the main burner or circulating
pump, as the case may be, responds.
5.
With the system HOT, examine all water connections for
soundness. Then turn OFF the gas, electricity and water
supplies to the appliance and drain down whilst the system
is still hot, in order to complete the flushing process. Refill
and vent the system and again check for water soundness.
6.
Finally, set the controls to the user's requirements.
The temperatures quoted below are approximate and vary
between installations.
27 GENERAL CHECKS
Deluxe model
Standard model
Advise the User of the precautions necessary to prevent
damage to the system and to the building, in the event of the
system remaining inoperative during frosty conditions.
5.
Explain the function and the use of the boiler thermostat and
external controls.
6.
Explain the function of the boiler overheat thermostat (
if fitted
)
and emphasise that if cutout persists, the boiler should be
turned off and a CORGI registered installer consulted.
7.
Explain and demonstrate the function of time and
temperature controls, radiator valves etc., for the economic
use of the system.
8.
If any Programmer Kit is fitted, then draw attention to the
Programmer Kit User's Instructions and hand them to the
Householder.
9. After installation, commissioning and customer hand-over
instructions please complete the
appliance log
book and leave this with the customer.
10.
Stress the importance of regular servicing by a CORGI
registered installer and that a comprehensive service should
be carried out AT LEAST ONCE A YEAR.
