General Installation Information.
External Installations.
The Rinnai Infinity 32e and HD70e are for external mounting only.
The unit is classed as a Category A3 flueless appliance as described by CEN CR1749.
Although BS 5440 does not relate directly to heaters in this category the rules must be
followed when positioning the appliance, especially with regard to other appliances,
openings, and boundaries. 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 appliance 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 (29 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 9. 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 appliance should not be
mounted higher than 3.5 metres from the ground or floor level unless the customer can
arrange permanent and safe access or can arrange another means of access, for
example, by means of scissor or boom lifts.
Multiple heater installations can be installed with the heaters manifolded together.
The design of the heater draws combustion air through the casing for the
external
model.
Heater guards and pipe cover boxes for security and safety are available from Rinnai.
