INSTALLATION INSTRUCTIONS - POSITIONING
External Models
The new Infinity Condensing 32e / HDC1500e is designed for 'Outdoor' Installation
only. As such, it must be located in an above ground, open air situation with natural
ventilation, without stagnant areas, where products of combustion are rapidly dispersed
by wind and natural convection.
The exhaust slot on the front should follow the same location guidelines as a balanced
flue terminal. Ensure that the flue terminal and hot water outlet connection cannot be
touched by children. The exhaust slot must be clear of obstructions and shrubbery.
Internal Models
The Infinity Condensing 32i / HDC1500i is designed for 'Indoor' installation only. It may
be installed 'Outdoors' in an enclosure if the requirements are satisfied. An enclosure is
defined as a compartment, enclosed area or partitioned off space primarily used for the
installing of the appliance. If installed in an enclosure, either Internally or Externally,
the location should be ventilated and provision must be made for the safe disposal of
any leaking water to an exposed location.
When positioning appliance the flue terminal clearances must be in accordance with
local 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 internal units Infinity may not be
installed in a humid area.
All Models
LPG appliances may not be installed in basements or below ground level.
The wall or structure on which the heater is mounted must be capable of supporting the
weight of the appliance (listed on page 52) and associated pipework. The heater must
be installed in a vertical position with the gas and water connections on the underside
pointing downward. 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 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.
THIS APPLIANCE MUST NOT BE USED AS A DOMESTIC SPA OR SWIMMING POOL
HEATER.
Please consider the location of the appliance and what is below it. As with any water
fitting there is a possibility that a connection or component could develop a leak over
time; or water may spill during servicing of the appliance. Rinnai can not be held
responsible for any consequential water damage so it may be necessary to fit a drain
pan under the unit.
