Reference Pressure Check; Spillage Check - Valor 4190 Installer's Manual

11.2 Check reference pressure
The appliance is pre-set to give the correct heat input at the inlet
pressure shown in section 1 of this manual. No adjustment is necessary.
Check the burner pressure by fitting a pressure gauge at the test point.
The test point is on the pipe situated below the bottom right corner of
the burner unit (See figure 32). Check the pressure with the appliance
alight and set at maximum output.
After checking, turn off the appliance. Remove the pressure gauge and
replace the test point sealing screw. Relight the appliance. Turn to the
maximum output position and test around the sealing screw for gas
soundness with a suitable leak detection fluid.
11.3

Spillage check

A spillage check must be made before leaving the installed
appliance with the customer. Make this with all the ceramic
coals in position.
11.3.1 Close all doors and windows in the room containing
the appliance.
11.3.2 Light the appliance and set the slide control to the
maximum burning position.
11.3.3 Leave the appliance on for five minutes.
11.3.4 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 33).
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 33).
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 6.4), remove the restrictor,
reseal the appliance and retest. If smoke is still not drawn into the appliance Disconnect
the appliance and seek expert advice.
11.3.5
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. Switch on any extractor fan installed in the same room as the appliance or a
connecting room. Open all doors and other openings between the fan and the appliance.
Recheck for spillage as above. 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.
