3. GENERAL REQUIREMENTS
The boiler must be installed in accordance with: The Gas Safety (lnstallation and Use) Regulations 1984 and the current issue of:
the Building Regulations, Building Standards (Scotland) Regulations, Local Building Regulauons, Model and local Water
Underuking Byelaws and IEE Wiring Regulations.
Detailed recommendations are stated in the following British Standards: 85689l :1988, B56798: 1987, 855!16:1990, BS5440:l:1990,
8S5440:2:1989 and B55449:1:1977 .
Note: Gas Safety (Installation and Use) Regulations 198^l: It is the law that all gas appliances are installed by competent persons,
in accordance with the above regulations. Failure to install applnnces conectly could lead to prosecution. It is in your own interest,
and that of safety to ensure that 'Jre law is comnlied wit}t.
4. DELIYERY
The unit is delivered in two packagcs ( I ) the cased boiler and (2) the fludterminal assembly type A, B, C, D or E as required.
In addition a 965 mm (38 in) fiuc extcnsion is avarlable. Under no circumstances should more than two extension kits be used.
A plug-in progr:rmmer kit is also available to fit inside the boiler casing. This programmer simplifies wiring and is suiuble for use
with all external control systems shown in the system wiring diagrams supplied with the boiler.
A lit from tie inside kit is available which enables the flue/terminal assembly to be fitted from inside the building.
A Vertex flue kit is available which allows the boiler !o be connecrcd to a vertical flue system.
A pump and by-pass kit is available which posiitions the pump in a readily accessible position, includes a built in by-pass which does
not rcquire adjusung and allows the combined cold feed and vent to be connected directly to the boiler. The kit includes an outer
casc extension which increases the boiler heieht to 861 mm.
5. GAS SUPPLY
The natural gas requirements are as follows:
Apollo30Si: l.l m3/h(37 ft3lh)
Apollo40Si: l.4m3lh(51ft3/h) Apollo50Si: 1.8 mt/h(62ft3/h)
The meter and supply pipes must be capable of delivering this quantity of gas in addition to the demand from any other appliances
in thc house.
Thc complete installation must be tested for gas soundness and purged as described in 85689l.
6. ELECTRICITY SUPPLY
210V - 50FIz via a fused double pole switch with a contact separation of at least 3 mm in both poles or preferably a fused 3 pin plug
and shuttered socket outlet (both complying with the requircments of BSl363) adjacent to the boiler.
Fuse the supply at 3 A. The minimum requirement for the power supply cable is that it should be a PVC sheathed flexible cord at
least 0.75 mm2 (24 x 0.2 mm) (code designation HO5 VV-F or HO5 VVH2-F) as specified in table 16 of 856500:1984.
All wiring external to the boiler shall comply with the latest IEE Wiring Regulations, and any local regulations which apply.
The appliance must be earthed.
In the evenl. of an electrical fault after inslallation of the appliance, preliminary elecnical systems checks must be carried out i.e.
Earth Continuity, Short Circuit, Polanty anC ResisLancc to Eanh.
7. AIR SUPPLY
The room in which the boiler is insnlled docs not rcquire a purpose provided air vent.
If the boiler is installed in a cupboard or compartment, permanent air vents are required in 0re cupboard or compartrncnt, one at high
level and one at low level, either dircct to the outside air or to a roorn. Both high level and low level air vents must communicate
with the same room or must be on the same wall to outside air. Both the high level and low level vent must each have a free area
as stated below. The frec area of each vent may be halved if the ventilation is provided directly from outside.
Apollo 30 Si: 99 cm2 ( 15 inz) Apollo 40 Si: 133 cm2 (20 inz)
Apollo 50 Si: I 65 cm2 (25 in2)
If the boiler is insulled in a cupboard or compartment with a door, allow at least 100 mm clearance between the front of the boiler
and the door for air movemenL
E. FLUESYSTEM
Five telescopic flue/terminal asscmblies are available and a fixed length, 965 mm (38 in), extension kil
The flue lengths are:
Sizp A: 123 - 175 mm (43A - 7 n)
Siire B: 17l -275mm(GA - lUAin)
Sizr C: 274 - 478 mm (|Glr - l8% in)
Siz.c D: 362 - 652 mm (l4t/e - 251/t in)
Sze E: 582 - lW2 mm (23 - 43 in)
Unless otherwise specified the C size flue/terminal will be supplied with the boiler.
The following method should be used to determine the required flue/terminal assembly.
R e a r f l u e A = C + 8 3 m m ( 3 % i n )
S i d e f l u e A = B + C + 1 2 7 m m ( 5 i n )
Where A = required flue length, B = inside wall to side of boiler and C = finished wall thickness.
If A is greater than 1092 mm (43 in) one or two extension kits may be used.
Note: The maximum allowable flue length is3022 mm (119 in).
