6.5 LOSS OF SYSTEM WATER PRESSURE
The pressure gauge indicates the central heating system pressure. If the pressure is seen to fall below the
original installation pressure of 1-2 bar over a period of time then a water leak may be indicated. In this event
conduct the re-pressurising procedure as shown. If unable to do so or if the pressure continues to drop a
Gas Safe Registered Engineer or in IE a Registered Gas Installer (RGII) should be consulted.
The boiler will not operate if the pressure has reduced to less than 0.3 Bar under this condition.
1. Ensure filling loop isolation valves are closed.
2. Remove the two caps
3. Attach on the filling loop.
4. Turn the filling loop isolation valves to the open position. The system will now fill.
5. Wait for pressure gauge dial to reach 1 to 1.5 bar.
6. Close the filling loop isolation valves.
7. Disconnect the filling loop at left hand side and angle upwards.
8. Attach the two caps as shown on point 2.
6.6 CONDENSATE DRAIN
The condensate drain must not be modified or blocked.
Blockage of the condensate drain, caused by debris or freezing, can cause automatic shutdown of the
boiler.
If freezing is suspected and the pipe run is accessible an attempt may be made to free the obstruction by
pouring hot water over the exposed pipe and clearing any blockage from the end of the pipe. If this fails to
remedy the problem the assistance of a Gas Safe Registered Engineer or in IE a Registered Gas Installer
(RGII) should be sought.
7. RESET BOILER
Press the reset button “K4” twice.

13. KEEP YOURSELF SAFE
Throughout the year it’s important to make sure that your gas appliances, such as a warm air heater, gas fire, cooker
and boiler are working safely and correctly. Did you know Gas Safe Register is the only official list of engineers who
are legally allowed to do work on gas and the gas appliances in your home? By law, all gas engineers must be on
the Gas Safe Register. The Register is there to help protect you from unsafe gas work.
In the right hands, gas is safe, but badly fitted and poorly maintained appliances can cause gas leaks, fires,
explosions and carbon monoxide poisoning. Carbon monoxide is a highly poisonous gas. You can’t see it, taste it
or smell it, but it can kill quickly with no warning but a carbon monoxide alarm would give you piece of mind but is
no substitute for an annual service.
Make sure you get your gas appliances regularly serviced and safety checked every year, by a Gas Safe registered
engineer. Annual maintenance not only helps keep your heating and hot water working properly; it helps keep you
and your family safe. If you’re a tenant, your landlord must arrange this every 12 months and provide you with a
Landlord’s Gas Safety Record.
You can set a free reminder at www.StayGasSafe.co.uk and Gas Safe Register will text or email you when your
appliances are due their next check.
All Gas Safe registered engineers carry a Gas Safe Register ID card. Before any gas work is carried out always
check the card and make sure the engineer is qualified for the work you need doing. You can find this on the back
of the card.
