MINIMUM DISTANCES FOR FIXING TO WALL
To allow access in the boiler for maintenance operations, the minimum distances shown below must be respected (fig. 1):
To facilitate installation, the boiler is supplied with a template for advance location of connections to pipes. In this way, you may simply hook
up the boiler when wall work is completed (fig.2).
Installation Instruction
1) With a spirit level, draw a line on the wall on which the boiler will be installed (fig. 1).
2) Position the top of the template on the line drawn with the spirit level (respecting the distances – see fig. 1) than mark the three points
for insertion of the 3 screw anchors or wall anchors for fixing the boiler hanging bracket. (choose proper anchors according to the wall
type). Next, mark the two points for insertion of the two screw anchors for fixing the JIG to wall.
3) Fix the hanging bracket and the JIG.
4) Make connections to the hot and cold water supply, to the gas pipe and to the heating system with the fittings supplied with the boiler
JIG. Connect pipes and valves as shown in the picture
5) Position the boiler paying attention to hang it to the hanging bracket
(do not lean the boiler on the JIG) and make final connections.
WATER CONNECTIONS
To facilitate installation, the boiler is equipped with a fittings kit (see fig. 3
and 4).
IMPORTANT:
Before connecting the heating system pipes, carefully clean the system
to prevent residual dirt from entering into circulation and negatively
affecting boiler function. Install a funnel with discharge under the safety
valve (calibrated to 3 bar) to collect water in case of leaking due to
overpressure. No safety valve is needed for the domestic water circuit,
but be sure that pressure does not exceed 6 bar.
• avoid using pipelines of reduced diameter;
• avoid the use of tight bends and adapters in important sections;
• clean out the system thoroughly before connecting up the boiler in
order to eliminate any residue left in the pipes and radiators.
N.B.: Make sure that the water and heating pipes are not used as earth
connections for electrical apparatus.
