Fitting The Boiler On The Wall - Potterton Flamingo RS40 Installation And Service Manual

4. Connect a suitable length of 22mm pipe with 90º elbow to the remaining 1" B.S.P. rear facing return connection.
(Central heating)
NOTE: Ensure that the fittings at the rear of the boiler do not protrude more than 92mm from the boiler backplate or
they may foul the wall.
RS4O
1. Connect a suitable length of 28mm pipe to the 1 in. B.S.P. upwards facing domestic hot water flow connection on
top of the heat exchanger.
NOTE: The flow pipe must be turned through 90º and routed through the cut-out in the back-plate, ensuring it is kept
within the confines of the cut-out. It must not project above or to the side of the backplate, otherwise it will be
impossible to fit the casing.
2. Connect a suitable length of 22mm pipe to the ¾ in. B.S.P. rear facing central heating flow connection. There is
room to split the flow behind the boiler if required. The circulating pump can be fitted on either the flow or return,
above or below the boiler; refer to
3. Connect a suitable length of 28mm pipe to the upper 1in domestic heating return connection.
4. Connect a suitable length of 22mm pipe to the lower 1in. central heating return connection.
NOTE: Ensure that the fittings to the return connections do not protrude more than 92mm from the boiler backplate,
or they may foul the wall.
B Fully Pumped System or Pumped Central Heating Only
RS5O
1. Connect a suitable length of 22mm pipe with elbow to either the R.H. or L.H. 1in B.S.P. rear facing flow
connections. The vent pipe should be connected into the flow pipe as close to the boiler as possible. Blank off the
remaining flow connection.
2. Connect a suitable length of 22mm pipe with elbow to either the R.H. or L.H. 1in B.S.P. rear facing return
connections.
3. The remaining connection can be blanked off or used to connect the cold feed.
4. The circulating pump can be fitted in any position on either the flow or return to suit the particular installation.
Refer to 'The System' and 'Pump Manufacturer's Instructions'.
RS4O
1. Connect a suitable length of 22mm pipe to the 1in B.S.P. upwards facing combined flow connection on top of the
heat exchanger. The vent pipe should be connected into the flow pipe as close to the boiler as possible. Blank off the
¾ in. B.S.P. rear facing flow connection. If it is necessary to use this ¾ in. B.S.P. flow connection a 22mm pipe
should be connected to it and the 1in. B.S.P. connection used for the vent pipe.
NOTE: The flow pipe must be turned through 90º and routed through the cut-out in the back-plate, ensuring it is kept
within the confines of the cut-out. It must not project above or to the side of the backplate, otherwise it will be
impossible to fit the casing.
2. Connect a suitable length of 22mm pipe to the lower 1in return connection.
3. The upper 1in return connection can either be blanked off or used to connect the cold feed.
4. The circulating pump can be fitted in any position on either the flow or return to suit the particular installation.
Refer to 'The System' and the 'Pump Manufacturer's Instructions'.
C Boiler Main Gas Cock
1. The main gas cock is supplied loose and must be fitted directly to the union nut and liner already assembled to the
inlet pipework on the boiler. The gas cock must be located in the most suitable position for operation, e.g. with its
operating plug facing towards the side of the boiler.
2. Connect a suitable length of 15mm pipe to the gas cock, terminating it in a length which can be easily connected to
the main supply, once the boiler is in position on the wall.

6. FITTING THE BOILER ON THE WALL

a. Stand the boiler on the floor in a vertical position, so that it is supported on its two metal legs. Lift the boiler onto
the air duct on the wall, locating the hook at the top of the boiler backplate, over the top edge of the duct.
b. Secure the boiler backplate to the air duct with the four screws adjacent to the flue hood position (Accessory Pack
D). Secure the combustion chamber to the air duct with the four screws with washers (Accessory Pack E), inside the
combustion chamber.
NOTE: Accessibility for fitting the four screws inside the combustion chamber will be improved if the main burner is
first removed.
c. Fit the fluehood to the boiler, using tie-rods which located either into holes in the back plate RS40 or holes in the
return edge of the backplate RS50S and angle strap, see
(Accessory Pack F); ensure an air tight seal is obtained between the fluehood, the top of the heat exchanger and the
backplate.
d. Fit the combustion chamber front cover, securing it with the four screws; ensure a gas tight seal is obtained.
