SECTION 8 SERVICING INSTRUCTIONS
8.1
General
To ensure the continued safe and efficient
operation of the appliance, it is recom-
mended that it is checked and serviced as
necessary at regular intervals.
The frequency of servicing will depend upon
the particular installation conditions and
usage, but in general, once per year should
be adequate.
It is the law that any servicing work is
carried out by a competent person such as
a Vokèra service engineer, approved
service agent, British Gas or other CORGI
registered personnel.
The following instructions apply to the boiler
and its controls, but it should be remem-
bered that the central heating and domestic
hot water systems will also require attention
from time to time.
8.2
Important Notes
WARNING: Having carried out preliminary
flame checks and before starting any
servicing work, switch OFF the mains
electricity supply and disconnect the plug at
the main isolating switch and socket. (If a
switch is used remove the fuse.)
Turn off gas supply at the gas service tap
fitted to the appliance.
Always test for gas soundness after any
service work and after exchanging any gas
carrying component.
8.3
Recommended Routine Servicing
8.3.1
Annual Servicing
When servicing is required the following
procedures should be carried out.
1. Inspect exterior for signs of damage and
deterioration, particularly of flue pipework
and electrical connections.
2. Turn off mains electricity and remove
front casing (see clause 8.4.).
3. Replace fuse if previously removed (8.2.
above) and turn on electricity. Run the boiler
for a few minutes in the domestic hot water
mode to permit inspection of its operation.
This is accomplished by opening a domestic
hot water draw off tap and inspecting burner
for yellowing of flame tip, flame lift off or
sooting.
