16. CLEANING
All cleaning should be carried out when the appliance is cold.
Normally the appliance should only need dusting. Dust etc.
can be brushed from the logs using a soft brush after detaching
the inner front unit and window – see installation instructions
sections 2.1.2 and 2.1.3. Dust etc. can also be removed from
the burners using a soft brush after removing the logs. When
cleaning the burners also check the aeration holes – see figure
24. If necessary brush clean the aeration holes.
If you are removing the logs, we suggest that they are
removed in the reverse order to that shown in the fuel bed
assembly instructions – see section 6. The logs, window and
inner front unit must be replaced as shown in the installation
instruction sections.
Coloring of the metal firebox with use is normal.
17. CHECKS
1. A periodic visual check of the pilot and burner
flames should be made. See figures 25 and 26.
Figure 25. Burner Flames
Figure 26. Pilot Flame
2. The appliance area must always be kept clear and
free from combustible materials, gasoline and other
flammable vapors and liquids.
3. Keep the area in front of the bottom grill clear to
prevent obstruction of the air flow to the burners for
combustion.
4. The flow of combustion and ventilation air must not
be obstructed. The venting system should be
examined by a qualified agency regularly. We
suggest annually.
18. SERVICING
The repair parts are shown on the repair parts leaflet. Please
always quote part number and description with requests for
spares.
18.1 FOR THE OWNER
If you require any attention to your appliance, contact your
supplier quoting the model number. It is helpful if the
appliance serial number is also quoted. This will be found on
the appliance rating plate which is located on the left side of
the appliance case. It is visible when the inner front unit is
removed.
18.2 FOR THE SERVICE ENGINEER
To aid servicing of the burner and manifold parts or for
installation of the optional circulation fan #710CFK, the
burner module can be removed as follows – see figure 27.
1. Remove the inner front and window – see sections
2.1.2 and 2.1.3.
2. Take all the ceramic parts out of the firebox and store
carefully.
3. Remove the front frame – see section 2.1.4.
4. To allow clear access for disconnecting the supply
line elbow uncouple the thermostat shaft – see
section 4.1.
5. Disconnect the gas supply line elbow at the appliance
inlet pipe union.
6. Remove the two screws holding the burner module to
the firebox sides. These are situated over the bottom
outside flanges, one each side of the firebox.
7. Remove the screw securing the sloping front heat
shield of the burner box to the appliance case.
8. Carefully slide the burner module forward until just
clear of the appliance case.
9. For most servicing operations the vent shutoff switch
wires can remain attached to the burner module. If
the burner module must be completely removed from
the appliance area loosen the thermocouple connector
at the back of the gas valve to detach the wires.
10. When refitting, reconnect the thermostat control shaft
as described in section 4.4.
