General Installation Information.
Internal Installations
The Rinnai Infinity 26i and the Rinnai HD50i are for internal installation in
conjunction with the Rinnai Power flue system.
The flue terminal clearances must be in accordance with the requirements of BS 5440.
Consideration should be given to other appliances, openings, and boundaries. Table and
Figure C.1 from BS5440-1:2000 is provided for your guidance.
The appliance must be mounted on a vertical wall or structure with the water and the gas
connections on the underside pointing towards the ground.
THIS APPLIANCE MUST NOT BE USED AS A DOMESTIC SPA OR SWIMMING
POOL HEATER.
Appliance Location.
The appliance should be placed as close as practicable 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
for further information.
Location of the appliance flue terminal must be in accordance with the clearances shown
on page 8. Ensure that the flue terminal and hot water outlet connection cannot be
touched by children. The flue must be clear of obstructions and shrubbery.
The wall or structure on which it is mounted must be capable of supporting the weight of
the appliance (22 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 page 10. 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 appliance must be in an accessible location. Sufficient clearances shall allow
access to, and removal of, all serviceable components. The unit should be mounted
high enough that the flue terminal will be above head height. If the terminal is below 2m
a guard must be put around it.
Multiple heater installations can be installed with the heaters manifolded together. The
minimum distance required between the heaters is based on the installation of the flue.
Refer to page 9 for more information on flue installation.
Although the flue and appliance have been specially designed to prevent condensation
in the flue for short runs (under 1.5m) care should be given to the placement of the
terminal to prevent risk in the unlikely event of condensation. Condensation water can
cause burns, and during winter could cause a slip hazard. It is the responsibility of the
installer to decide the best place for the terminal as every situation is different.
