Rinnai REU-A1620WG-ZK Infinity Graphite Range

Rinnai INFINITY Graphite range specification

Description
Designed and made in Japan, the Rinnai INFINITY Graphite units are external continuous-flow gas hot water heaters with inbuilt frost protection and status monitors. They have electronic ignition and require electricity to operate. They are factory-set to deliver water at 50 °C.

Scope of use
Suitable for RESIDENTIAL external applications only. To be externally mounted on an outside wall and located as close as possible to the most frequently used hot water outlets to reduce the delay for hot water delivery. They are not suitable as a spa or swimming pool heater or for hydronic applications. Hard or acidic water will need to be treated to use this product.

Direct electronic ignition
Line pressures| NG – 1.13kPa, LPG – 2.75 kPa
Line pressure maximum| 3.5 kPa (maximum standing pressure under abnormal intermittent conditions is

5.0 kPa). In the case of commercial metering, (i.e. 35-37 kPa coming in), there may be a requirement to regulate the incoming pressure down.

Ingress protection rating| IPX5| IPX5| IPX5
Power consumption| Normal 47 W, automatic frost protection 68 W| Normal 66 W, automatic frost protection 68 W| Normal 63 W, automatic frost protection 92 W
Noise level (1 m away)| 50 dB(A), some people are susceptible to low level noise. This needs to be considered if locating near a bedroom.
Safety devices| Flame failure, boil-dry protection, overheat protection, fusible link, pressure relief valve, and combustion fan RPM check.
Water supply| Nominal operating pressure: 200-1000 kPa.

Minimum operating water flow will depend on setpoint and inlet temp.

Please note : If the water inlet pressure drops below the minimum value, operation of the INFINITY is not guaranteed.

Weight| 13 kg| 15 kg| 18 kg

Positioning: General flue terminal clearances
The following has been adapted for Rinnai INFINITY water heaters from AS/NZS 5601 6.9.3 Location of flue terminals around the perimeter of a building of structure. Always reference the latest version of the standard for the most up-to-date information.

Please note : Rinnai recommends 1500 mm to give enough clearance for the pipe work, and to safely expel flue gases

| 300
c| From a return wall or external corner1| 300
d| From a gas meter (M)2| 1000
(see Clause 5.11.5.9 for vent terminal location of regulator)
(see Table 6.9.6 for New Zealand requirements)
e| From an electricity meter or fuse box (P)2,3| 500
f| From a drain pipe or soil pipe| 75
g| Horizontally from any building1 structure or obstruction facing a flue terminal| 500
h| From any other flue terminal, flue cowl , or combustion air intake1| 300
j| Horizontally from an openable window, door, non-mechanical air inlet, or any other opening into a building with the exception of sub-floor ventilation:
Appliances up to 150 MJ/h1 input| 300
Appliances over 150 MJ/h input up to 200 MJ/h1| 300
All fan-assisted appliances , in the direction of discharge| 1500
k| From a mechanical air inlet, including a spa blower| 1000
n| Vertically below an openable window, non-mechanical air inlet, sub- floor ventilation, or any other opening into a building with the exception of weep holes:
For appliances over 150 MJ/h input| 1500
1 Unless appliance is certified for closer installations.

2 Minimum clearances d and e also apply to any combustion air intake openings of appliances.

3 Prohibited area below the electricity meter or fuse box extends to ground level.

• NOTE 1 : Where dimensions c, j, or k cannot be achieved, an equivalent horizontal distance, measured diagonally from the nearest discharge point of the terminal to the opening, may be deemed by the Technical Regulator to comply.

• NOTE 2 : See Clause 6.9.4 for restrictions on a flue terminal under a covered area.

• NOTE 3 : A flue terminal is considered to be a source of ignition. AS/NZS 1596 specifies the minimum clearances required from a flue terminal to an LP Gas Cylinder (see Figure 1.5(A), Appendix I).

• NOTE 4 : For minimum clearances not addressed above, acceptance should be obtained from the Technical Regulator.

• NOTE 5 : Contact the appliance manufacturer if in doubt that the minimum clearances will provide adequate thermal protection of surfaces adjacent to the flue terminal. Additional
  measures may be required.
