Rinnai INFINITY HD26 Installation Information

GENERAL INSTALLATION INFORMATION
REU-V26 FFU / REU-V26 FFUC
You must install this appliance in accordance with these Instructions and all
regulatory requirements which exist in your area. Applicable publications
may include:
• NZS 5261 - Gas Installations
• AS/NZS3500 - National Plumbing and Drainage
• AS/NZS3000 - Wiring Rules
• Building Codes of New Zealand
THIS APPLIANCE IS DESIGNED FOR INDOOR INSTALLATION. IT MAY
BE INSTALLED OUTDOORS
REQUIREMENTS OF NZS 5261 PART 13.5 ARE SATISFIED.
IT MUST BE MOUNTED ON A VERTICAL WALL OR STRUCTURE WITH
THE WATER AND GAS CONNECTIONS ON THE UNDERSIDE POINTING
TOWARDS THE GROUND.
IT MUST BE INSTALLED WITH THE RINNAI INFINITY FLUEING SYSTEM.
NON RINNAI FLUEING SYSTEMS MUST NOT BE USED.
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, appliances can be strategically
placed to service outlet points with minimal delay time. Contact Rinnai
New Zealand for further information.
The appliance must also be located so that the flue terminal exits the
building at a suitable point. The maximum length of the flue is 9 metres
with a maximum of three 90° bends. Both a horizontal (wall) or vertical
(roof) terminal are available. For detailed information regarding the Flue
refer to the 'Flue Installation Instructions for Infinity Internal Water
Heaters' supplied with the flue terminal or contact Rinnai.
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.
AC230V, 10A earthed power point must be provided adjacent to the
appliance. It must be clear of the gas and water connections to the
appliance, flue and water pressure relief valve. The power cord of the
appliance is 1500 mm long.
If a horizontal (wall) terminal is used, the location must be in accordance
with the clearances shown in Figure 3 of NZS 5261 which is reproduced
right side. Ensure that the flue terminal cannot be touched (particularly
by children). A flue guard is available to prevent direct contact with the
terminal. The flue must be clear of obstructions and shrubbery.
If a vertical (roof) terminal is used, the requirements of NZS 5261 apply.
Clearances must be in accordance with the diagram shown in fig 1
bottom right.
It is the installer's responsibility to ensure that the current requirements
of NZS 5261 are met.
PIPE SIZING
This appliance can use up to 199 MJ/h of gas. If the gas pipe sizing is
insufficient the customer will not get the full performance benefit. Gas
pipe sizing must consider the gas input to this appliance as well as all
the other gas appliances in the premises. The gas meter and regulator
must be specified for this gas rate. An approved sizing chart such as the
one in NZS 5261 should be used.
Water pipe sizing and layout should be performed in accordance with
AS/NZS3500. All hot water pipe work should be insulated to optimise
performance and energy efficiency.
