Refer to Sections 4 & 5 and Tables 4 to 8. 11.1.3 Fixing Holes and Flue Opening Hold the template to the wall. Check that the template is level. Mark the position of the fixing holes and the flue opening. Refer to Fig 13. Mark the position of the bottom fixing point for a screw or optional security bolt. Fig. 13 .

Flue and wall plate Flue fixing position 11.1.4 Flue Preparation (i) Drill the hole for the flue at 110mm diameter. (ii) Fix the wall-mounting plate - do not fully tighten the screws. (iii) Measure the wall thickness L - Min 220mm, Max 375mm. If L is less than 220mm thick then it is necessary to cut the flue. To do this subtract L from 220 and cut all flue parts by this amount. Ensure that the ducts are square and free from burrs. Always check dimensions before cutting. The minimum length L is 100mm with cutting. (iv) Adjust the telescopic flue assembly to a length L+5mm and secure with the screw supplied. Refer to Fig. 14. (v) Apply the plastic tape onto the duct in contact with the wall (position shown in Fig. 14.). (vi) Remove the inner flue duct (with the fixing bar). (vii) Push the outer duct assembly through the wall mounting plate and wall. Tighten the wall mounting plate fixing screws after checking that the plate is level. Fig. 14 .

Rear of casing Gasket 11.1.5 Boiler Preparation (i) Remove the appliance casing by releasing the screw at the centre base. Disconnect the earth connection at the base and lift off. (ii) Release the four screws and remove the inner casing cover. (iii) Release the two wing-nuts and remove the combustion chamber front panel. The cover is located into notches at the base of the side plates. Leave the stainless steel baffles in place. (iv) Disconnect the fan electrical terminals and the sensing tube from the junction pieces. Slide the flue hood/fan assembly out of the boiler. (v) From the literature pack take the self adhesive gasket and stick around the rear flue opening on the outside of the casing ensuring that the fixing holes are not blocked (see Fig. 14b). 3 6 5 11.1.6 Install the Boiler IMPORTANT: Thoroughly flush the system before connecting the boiler. Any system cleanser must be flushed from the system before adding any inhibitor. (i) Lift the boiler onto the wall mounting plate. See Fig. 15. (ii) Level the boiler using the two levelling feet at the base of the back panel. (iii) Fit the bottom fixing screw (or optional security screw). (iv) Connect the gas supply using the nut and olive supplied in the literature pack - details of the position are shown in Fig. 3. (v) Connect the flow and return pipes to the system. It is important that the flow and return pipes are not fixed near to the boiler using clips that put a strain on the connections. A drain point should be fitted close to the appliance if bottom connections are made. Always consider the possible need to disconnect and remove the boiler. 11.1.7 Installation of Flue onto Boiler (i) Pull the flue into position so that the holes in the flange line up with those in the case NOTE: The correct rectangular flue restrictor must now be fitted when the boiler is on the wall. 9/14CBi and 14/19CBi 19/24CBi 66 X 62 (Rectangular) 77 X 62 (Rectangular) (ii) From the inside, place the correct restrictor in position over the flue opening and using the screws provided, fix through the inner casing into the flue system. (iii) Slide the inner flue duct with fixing bar into the flue. (iv) Slide the fluehood and fan assembly back into position engaging the fan outlet into the inner duct assembly and reconnect the fan electrical terminals (polarity is not important). Reconnect the pressure sensing tubes onto the junction pieces. See Fig. 16. (v) Ensure that the combustion chamber is slotted underneath the flue hood and re-assemble with the combustion chamber front and 'J' bolts. 16 Fig. 15 .
