Appliance location
External models
External models are designed for outdoor installations only. They must be located
in an above ground open-air situation with natural ventilation, without stagnant
areas, and where gas leakage and products of combustion are rapidly dispersed
by wind and natural convection.
They must be mounted on a vertical structure with the water and gas connections
on the underside pointing downwards. For appliances installed on elevated
structures or under floors specific requirements apply. Refer to NZS 5261 for
details.
This appliance must be located so that the flue terminal exits the building at a suitable point,
refer 'Minimum Clearances Required for Flue Terminals', NZS 5261:2003.
Manufacturer's instructions for model REU-KM3237WD (EF250); for reference j, gas
appliances over 200 MJ/h input, use ≥ 300 mm.
When multiple units of the same model are installed on the same vertical face, with the flue
terminals at the same height, they can be installed next to each other (as shown).
All models
This appliance must be placed as close as possible to the most frequently used hot water outlet
or outlets to minimise the delay for hot water delivery.
For installations where the distance between the water heater and the outlets is considerable,
a flow and return system can be used to minimise the waiting time for hot water delivery.
Alternatively, multiple appliances can be strategically placed to serve different outlets. Contact
Rinnai for further information.
An AC 230 V, 10 Amp, earthed power point must be provided adjacent to the appliance. For
outdoor installations, this power point must be weatherproof. It must be clear of the gas and
water connections to the appliance and also the flue exhaust and water pressure relief valve.
The power cord of the appliance is 1.5 m long.
All appliances must be installed to ensure access can be gained without hazard or undue
difficulty for inspection, repair, renewal or operational purposes. Sufficient clearances shall
allow access to and removal of all serviceable components.
Appliances should not be mounted higher than 3.5 m above the ground or floor level unless
the customer can arrange permanent and safe access or can provide another means of access
such as scissor or boom lifts.
