Flame Supervision And Spillage Monitoring System; Check Reference Pressure - Valor Brava 347 Installation And Owner's Manual

INSTALLER GUIDE

7.2 Flame supervision and spillage monitoring system.

The pilot unit incorporates a system that will automatically shut off the gas supply if
the pilot flame goes out or if there is insufficient oxygen due to spillage or lack of
ventilation.
Check that the system operates properly as follows;
1. Light the appliance. Set at position 5 and leave for one minute.
2. Turn back to "OFF" to extinguish the pilot. Note the time when the pilot goes
out. Listen for a snap sound at the gas tap. Note the time when the sound is
heard. An electromagnetic valve shutting off the gas supply through the tap causes
this sound. The valve is located in the body of the tap. The valve should operate
within 60 seconds of the pilot going out. If the valve does not operate within this
time limit do not allow the appliance to be used until the fault has been corrected.
This monitoring system must not be adjusted, bypassed or put out of
operation.
This monitoring system, or any of its parts, must only be exchanged using Baxi
authorised parts.

7.3 Check reference pressure.

The appliance is pre-set to give the correct heat input at the inlet pressure shown in
section 3 of this manual. No adjustment is necessary.
1. Ensure that the fire is OFF then detach the control knob from the spindle. Remove
the fascia and replace the control knob.
2. Check the burner pressure by fitting a pressure gauge at the test point. The test
point is on the gas tap. Check the pressure with the appliance alight and set at
maximum output (Control position 5).
3. 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. Turn the fire OFF and detach the control knob from the spindle.
4. If all the above checks are satisfactory, continue with the installation. If not, check
the control and ignition circuitry and components as described in the servicing section
of this manual.
