10.FULL OPERATING CHECKS
10.1
RECHECK CONTROL SETTINGS
Now that all the ceramic fuel effects are in position,
the control operation must be fully rechecked.
10.1.1
Make sure that the isolating valve at the inlet elbow
is open.
10.1.2
Depress the control knob and turn anticlockwise
partially towards the “PILOT/IGN” position until
some resistance is felt. Keep depressed at this
position to purge air from the system then, while
keeping it depressed, turn fully to the “PILOT/IGN”
position. A spark should be generated at the pilot
while turning. The spark should ignite the pilot
.
Check that the pilot flame is visible - see section
9.5.2.
10.1.3
When pilot ignition has been achieved, keep the
control knob depressed for approximately ten
seconds to allow the thermocouple probe to warm
up and then release it. If the pilot does not remain
alight, ensure that the pilot orifice is clear.
10.1.4
When the pilot is alight and stable, partially depress
the knob and turn to “LOW”. The pilot should then
light the main burner at its low setting. There may
be a delay of up to four seconds between the pilot
lighting and ignition of the gas at the main burner.
This is normal and is due to the time required to fill
the main burner compartment with sufficient gas for
ignition.
10.1.5
When the burner is operating properly, partially
depress the knob and gradually turn it anti-
clockwise. The burner flames should gradually
increase until the knob reaches the “HIGH”
position.
10.1.6
Partially depress the control knob and turn back to
“PILOT/IGN”. The main burner flames should be
extinguished but the pilot should remain alight.
10.1.7
Partially depress the control knob and turn to
“OFF”. The pilot should be extinguished.
10.2
CHECK FOR SPILLAGE
A spillage check must be made before leaving the
installed appliance with the customer. Make this check
with the appliance fully installed with the ceramic fuel
effects and front surround in position.
10.2.1
Close all doors and windows in the room containing
the appliance.
10.2.2
Light the appliance and turn the control knob to
“HIGH”
10.2.3
Leave the appliance on for five minutes.
10.2.4
There are two types of smoke match holders. One has a
copper finish, the other is plain steel. Please apply the
relevant parts of the spillage test instructions
.
Place the smoke match tube into the convection box
at the right hand side and immediately below the
black top cross member. Angle it at approximately
45° to the horizontal.
Copper finish tubes
:
Insert the tube so that the raised
ring (approx. 25mm from the end) touches the
outside surface of the edge of the cross member
(figure 24).
Plain steel tubes:
Insert the tube so that the neck of
its flared end touches the inside surface of the edge
of the cross member (figure 24).
Keeping the raised ring (for copper finish tubes) or
neck of flared end (for plain steel tubes) in contact
with the edge of the cross member, slide the tube to
the left until you feel it enter the notch in the edge of
the cross member. Make sure that the tube is pointed
upwards at 45º to the horizontal.
The installation is satisfactory if the smoke is drawn
into the appliance. If the smoke is not drawn into the
appliance, leave the appliance alight at the maximum
setting for a further ten minutes and then repeat the
test. If the smoke is still not drawn into the
appliance, inspect the sealing to the fireplace
surround. If the sealing is satisfactory but the
appliance is installed with the flue restrictor (see
section 6.5), remove the restrictor, reseal the
appliance and retest. If smoke is still not drawn into
the appliance
Disconnect the appliance and seek expert
advice.
10.2.5
If the above test is satisfactory, open all internal
connecting doors, hatches, etc. in the room. Keep all
doors and windows that open to the outside of the
building closed. Recheck for spillage as above. If an
extractor fan is installed in the same room as the
appliance or a connecting room, check that spillage
does not occur with the fan operating and all doors
and other openings between the fan and the
appliance open.
If the smoke is drawn into the appliance, continue
with the installation. If the test is not satisfactory,
Disconnect the appliance and advise the customer of
the cause of failure.
