Mounting Of Appliance; Service Connection Points; Pipe Sizing; Water Supply - Rinnai HD210e Operation & Installation Manual

GENERAL INSTALLATION INFORMATION
If a horizontal (wall) terminal FFSSKIT is used, the location MUST BE in accordance with Section 6 and Figure
6.2 of AS/NZS 5601. An extract (in part) has been reproduced in the "Appliance Flue Terminal" section of these
instructions on page 18.
If a vertical (roof) terminal FFSSROOFCOWL is used, the location must be in accordance with Section 6 and
Figure 6.2 of AS/NZS 5601. An extract (in part) has been reproduced in the "Appliance Flue Terminal" section of
these instructions on page 18.

Mounting Of Appliance

The wall or structure on which the units are to be
mounted MUST BE capable of supporting these
weights and the associated pipe-work. Refer to "Table
2. Supply, Flow rates, Weights & Service Connections"
on page 30 for specific model weights.
Ensure that suitable fixing screws or bolts are used
to secure the units to the wall, in accordance with AS/
NZS 5601 section 6. Wooden plugs shall not be used.
The top bracket has a keyhole slot so that the appliance
can be positioned by hanging it on one screw, once in
position the appliance can then be fully secured with
the application of further appropriate fittings.
The appliance can be mounted directly against the wall
or structure. There is no need to use, non combustible
sheeting or leave an air gap between the appliance
back panel and the wall or structure to meet the
temperature hazard requirements of AS/NZS 5601.

Service Connection Points

Refer to "Table 2. Supply, Flow rates, Weights & Service Connections" on page 30 for model specific connection
/ fitting dimension details.
An Approved full flow isolation valve and disconnection union MUST BE fitted to the cold water and gas inlets.
A non return valve is not required on the water inlet unless required by local regulations.
Isolation Valves MUST be fitted to the appliance via a connection union.
If may be necessary to fit a temperature limiting device for delivery to areas used primarily for the purposes of
personal hygiene. Refer to "Hot Water Delivery Temperature" on page 17.
Purge gas and cold water supply lines to remove air and swarf before final connection of the appliance. Swarf in
either the gas or water supplies may cause damage.

Pipe Sizing

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 AS/NZS 5601 should be used. Refer to "Table 2. Supply, Flow rates,
Weights & Service Connections" on page 30 for model specific gas consumption details.
Water pipe sizing and layout should be performed in accordance with AS/NZS 3500. All hot water pipe-work should
be insulated to optimise performance and energy efficiency.

Water Supply

The appliance is intended to be permanently connected to the water mains.
Refer to "Table 2. Supply, Flow rates, Weights & Service Connections" on page 30 for model specific operational
water pressure limitations. Approved pressure limiting valves may be required if the 'Maximum' rated water supply
pressures in Table 2 are exceeded. To achieve the rated flow, the 'Minimum' water supply pressures in Table 2
must be supplied.
The water heaters will operate at lower pressures but will not achieve the rated flow. Contact Rinnai for 'gravity
fed' or 'low pressure' installations.
