INSTALLATION INSTRUCTIONS - POSITIONING

Appliance Location.

The wall or structure on which it is mounted must be capable of supporting the weight of the appliance (15 kg) and associated pipework. Ensure that suitable screws or bolts are used to secure the water heater to the wall. Bracket and fixing hole locations are shown on the template included. The top bracket has a keyhole slot so that the appliance can be hung on one screw, and then the other fixings can be added to secure the unit.

The heater must be installed in the vertical position with the gas and water connections on the underside pointing vertically downward. The heater must be installed internally.

The appliance should be placed as close as practical to the most frequently used hot water outlet point or points to minimise the delay time for hot water delivery. For installations where the distance between the unit and hot water outlet points is considerable, the appliance can also be fitted in a 'flow and return system' which minimises the waiting time for hot water delivery. Alternatively, multiple appliances can be strategically placed to service outlet points with minimal delay time. Contact Rinnai or your supplier for further information.

When positioning appliance the flue terminal clearances must be in accordance with lo- cal requirements. Consideration should be given to other appliances, openings, and boundaries. Multiple heater installations can be installed with the heaters manifolded together. The minimum distance required between the heaters may then be based on the necessary clearances between flue terminals.

The appliance must be in an accessible location. Sufficient clearances shall allow access to, and removal of, all serviceable components. The following clearances should be followed.

If the unit is installed on a combustible wall such as wood there must be a 45mm gap between the wall and the back of the unit. Brackets are avail- able to space the unit this far off of the wall.

In case the side wall next to the appliance is flammable material there must be at least 50mm between the side of the appliance and the combustible wall.

The illustration shows the clearances necessary for servicing, on a non- combustible wall.
