Fit The Boiler; Connect The Pipework - Baxi LUNA HT 380 Notice D'installation Et D'entretien

1 Thoroughly flush out all the water pipework.
WARNING
Ensure that all the plastic caps are removed from the boiler connections.
2 Secure all the valves/fittings to the boiler
• Ensure the washers supplied are utilized.
• Valves and fittings should be facing the rear wall.
• Fit the union bends to the valves.
Note
a. If soldering to the boiler union bends, ensure that the bends are not connected to the valves, otherwise the internal
seals may be damaged.
b. Ensure the 3/4" / 22.2 mm isolating valve with the filter is fitted to the heating return connection.
c. Fit the pressure relief valve connection vertically before the heating return isolating valve.
3
Connect the system pipework to the boiler.
Note
Do not forget that the pressure relief valve discharge pipe must be routed clear of the boiler to a drain in such a
manner that it may be seen, but cannot cause injury to persons or property.
4 Ensure that all the valves are closed (spindle flats at right angles to valve) and do not turn on the water or gas supplies
at this stage.
5 Connect the condensate outlet to the condensate trap supplied with the boiler. Connect the condensate trap to a
drain, making sure there is a continuous slope. Horizontal sections must be avoided.
WARNING
The boiler and its individual shutoff valve must be disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of 1/2 psi (3.4 kPa - 34.47 mbar).
The boiler must be isolated from the gas supply piping system by closing its individual manual shutoff valve during
any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.5 kPa).
The boiler shall be installed such that the gas ignition system components are protected from water (dripping,
spraying, rain, etc.) during appliance operation and service (circulator replacement, condensate trap, control
replacement, etc.)
