NOTE:
If the appliance will not be used for an extended
period, such as during summer or storage, disconnect
power by setting the valve Master switch to the Left
(O). It is also advisable to shut off the main gas supply
line valve and remove the batteries from the control
valve to prevent corrosion.
Maintenance
The complete installation, which includes the gas supply,
the actual appliance and the vent system, must be
inspected annually. The inspection must be carried out by
qualified service engineer.
Battery Replacement
The TESC valve is powered by 3, AA 1.5v alkaline
batteries.
1. Slide the white Master switch to the left (O) posi-
tion to disconnect power, Fig. 18.
2. Press and push the battery cover release lever to the
left to open the compartment.
3. Orient the batteries as displayed on the back of the
compartment.
External Maintenance
Painted products may change color after some years
of usage. The surface should be cleaned and brushed
free of any loose particles before new stove paint is
applied.
Enameled products must only be cleaned with a soft,
damp cloth and only when the surface is cold. Do not
use water or soap. Enamel surfaces stain easily when
hot. A solution of vinegar and baking soda may be
used to remove stains.
Annual Service
Annual service of the appliance includes the
following check points.
1. Lighting and inspection of the pilot flame (see
the section - Inspection of the Pilot Flame above);
2. Cleaning the glass: Use only ammonia-free, non-
abrasive glass cleaning compounds. Polish using
newspaper.
3. The gasket around the glass must be inspected
annually for wear and replaced if necessary;
4. Check if the textured ember stones need to be
replaced; they will whiten over time.
5. Look for soot. It could be a result of the ceramic
logs not being properly aligned or completely
engaged with the associated mounting pins.
Also confirm that the exhaust restrictor has been
adjusted correctly. See Vent Restriction, page 7.
6. Check the gas pressure if other gas equipment is
connected to the gas supply.
7. Look for signs deterioration or corrosion within
the appliance, pilot assembly, and vent system.
8. Look for obstructions in the vent system (such as
bird’s nests, or branches from bushes and trees).
Keep vent terminations clear. Inspect to confirm
the integrity of all pipe seams and fasteners
