n) To adjust the LOW FIRE rate, use the ‘-‘ or ▼ buttons to set the
controller to  burner output. After the burner has stabilized,
adjustments can be made to ‘Low Fire’ adjuster on the gas valve
(clockwise to increase, anti-clockwise to decrease the CO). Af-
ter each adjustment, let the burner stabilize for a minute, then
check levels again. See Fig .b. Continue until the CO levels
are as listed in the table above.
o) ALWAYS re-check both HIGH and LOW  re settings after any
adjustments. Adjustment to the HIGH  re setting may a ect
the LOW  re setting, and visa-versa.
p) When the HIGH and LOW  re CO levels are as listed in the ta-
ble above, remove the  ue gas analyzer and replace the Flue
Sample Test Point Cap.
q) Upon completion of the burner commissioning and combus-
tion adjustments, the integrity of the  ue system must be checked (if balanced  ue). Operate the boilers
in Commissioning Mode, HIGH FIRE, as previously detailed.
Fit the outer casing of the appliance whilst it is operating at HIGH FIRE, and monitor the operation. If the
 ame extinguishes within  minutes of operation at HIGH FIRE, and the boiler tries to re-ignite, then the
 ue system must be checked for leakage / re-circulation of combustion products from the inner  mm
∅ Exhaust Pipe to the outer  mm ∅ Air Pipe.
Important Notice.
On completion of the above procedure it is imperative that the Flue Gas Test PointCap is re- tted, and
that the controller is not left in the Commissioning Mode. Press the MODE button to ensure that the ap-
pliance IS NOT left in the Commissioning Mode.

On completion of the commissioning detailed in sections . through to . inclusive, the boiler controller
must be returned to either the ‘STAND-BY’ or ‘AUTOMATIC’ mode.
THE CONTROLLER MUST NOT BE LEFT IN THE COMMISSIONING SETTING.
Fit the boiler case ensuring that the case properly engages onto the rear chassis, and that any cables have
not been trapped between the case and the chassis. Secure the casing with the two ¼ turn latches.
WARNING
THIS APPLIANCE MUST NOT BE LEFT TO OPERATE WITH THE OUTER CASING REMOVED.

As with all Gas Appliances, we would highly recommended that a competent heating engineer services the
Procon , ,  &  boilers, at least every  months. This is assuming a normal daily usage of  –  hours.
If however the boiler is to be operated  hours a day,  days, we would recommend services every 
months
The Procon , ,  &  boilers will display an E SMALL Error Code when  months has lapsed, indicat-
ing that the appliance requires a Routine Service Inspection. This code will also be displayed on the QAA and
remote RVA controllers, if  tted.
If the Installer/Commissioning Engineer is unable to undertake the Routine Service Inspection, as detailed
Section ., please contact RVR Technical Service Department, who will be able to arrange the Routine Service
Inspection to be undertaken.
