Open the gas tap and check the gas couplings below the gas valve and
on the mounting bracket for leaks.
Switch on the electrical supply to the appliance
Switch on the appliance, using the On/Off button on the operating panel.
Check the front cover and the connection of the fan to the front cover for
leaks.
9.1.3 Note for CFS systems with Non Return Valve (flue gas)
When refitting the fan, the NRV MUST be refitted (see diagram). Fold the
silicon valve (1) of the NRV carefully into a U-form.
Place the valve + holder (1+2) into the hole of the front plate, making sure
the valve is placed in the correct position (direction toward the front plate
as shown).Replace the fan + seal back on the front plate, and screw both
nuts (4) tight, making sure the valve stays in the right position.
9.1.4 Checking the condensate discharge
See the diagram in § 4.6.
Clean the condensate trap and the condensate discharge pipe.
After cleaning, fill the trap with water.
9.1.5 Inspect air supply/flue gas discharge system
Inspect the air supply/flue discharge system throughout its entirety,
ensuring that it is in sound condition with no damage to the pipes or joints.
Inspect the terminals ensuring that they are clear and unobstructed.
9.1.6 Checking the gas-air control
Check the gas-air control as given in § 7.9, and adjust as necessary.
9.1.7 Check the CO/CO
2
ratio
The CO/CO2 ratio should be checked on each service. See section 7.10
9.1.8 Completion of inspection and service
Note
After servicing, the Benchmark Checklist
and Service Record (located at the back
of this manual) should be completed and
signed and the manual left with the
customer.
Fit the front panel and replace the screws at the bottom of the appliance.
Check the CH system water pressure shown on the display, which should be
minimum 1 bar and maximum 2 bar for a cold system.
Check the pressure of the expansion vessel is 1 bar, using a pump into the
Schroeder valve if necessary.
Check the central heating system and the hot water supply for leaks and check
the boiler, controls and system for correct operation.
Check the corrosion inhibitor concentration level within the CH system,
topping up when necessary.
