Test for adequacy of air supply is to-:
Set the oil fired appliance going, close all doors and windows in the room, turn on the
extractor fan to its maximum capacity, light the open fire and let it get well established.
Test for adequate maintenance of chimney vacuum on the appliance, both before and after the
extractor fan is turned on, with the open fire going.
During the tests the flue vacuum of the oil fired appliance should be measured to see if there
is any noticeable reduction beyond that called for in these instructions.
WARNING
Instructions on ventilation must be adhered to.
4-4a WATER HEATING
Colibri Boilers are all high water content boilers and as such can easily replace solid fuel
installations with the minimum of complication.
Before you start to install a water heating Colibri Boiler remember that the central heating
system must comply with BS:5449 part 1.
If a combined heating and domestic hot water system is to be used, then a double feed indirect
hot water storage cylinder to BS:1556 part 1 should be used.
In order to prevent the build up of scale and corrosion a suitable inhibitor should be used.
The system must be correctly vented.
The height differential between the header tank and the appliance must not exceed 15.2
metres (50 feet) Where a common return is used an injector tee must be incorporated into the
system to ensure adequate primary circulation when the circulating pump is operating. (see
detail in FIG16)
The system must incorporate a gravity circuit which will normally heat the domestic hot water
and an un-valved radiator or radiators with an output of at least equal to the minimum water
heating output of the appliance. (see technical spec for details)
When the appliance is not connected to a domestic hot water system a gravity system must
still be used with the unvalved radiator(s) on the gravity circuit having a total output of at
least the minimum output of the appliance, this is to prevent boiling in case of pump failure.
Min. pipework in the primary circuit must be 28mm diameter and the gravity flow pipe must
rise continuously from the boiler to the open vent.
Typical systems are shown in illustrations FIGS 15,16,18,19 and 20
Connect the heating system to the boiler ensuring that the primary flow pipe rises
continuously from the appliance to the vent.
Fill the system with water and check for leaks and air locks.
APPLIANCE CONTROLS
The appliance can be controlled via -:
The oil control valve which is fitted with-:
1. A manually operated oil flow control knob
2. A manually set, automatic thermostat, built into the oil control valve.
3. A manually and automatically operated oil cut off lever, built into the oil control valve.
4. An automatically operated safety shut off thermostat, built into the oil control valve which
trips the oil flow cut off lever mentioned in 3 above.
The valve operates as follows, it has flow control potential from mini to maxi via six
graduations and so the appliance can be manually controlled from MINI to MAXI by simply
turning the flow control knob (1 above), in addition it also has a water sensing thermostat and
an automatic safety oil cut off device should the appliance water temperature exceed 90
degree C.
The water sensing thermostat will automatically control the boiler water temperature at what
ever setting is required up to a maximum of 70 degree C. (2. above) and it is operated by a
control knob situated alongside the oil flow control knob.
