LOCATION
When positioning the heater, the main variables governing the location are Flueing and Warm Air Distribution.
Combustible clearances
The heater MUST NOT be installed where
curtains, furniture or other combustible materials
could come into contact with the re while it is
operating. The 150 mm side clearance, measured
from the edge of the glass, includes side walls.
The 1000 mm clearance is in front of the re.
Hearths
A hearth is not necessary but can be used for
decorative purposes. It MUST NOT obscure the
front of the re or obstruct the re in any way. For
more information refer next page.
Floor protection
Heat radiating from the re may a󰀨ect the
appearance of some materials used for ooring
such as vinyl planks, carpet, cork, or timber. To
avoid this occurring it is recommended a mat be
placed in front.
IMPORTANT
Carpet MUST NOT be tted hard
up against the re as it will a󰀨ect
operation
Mantels and surrounds
Combustible mantels and surrounds require
clearance from the unit to minimise the risk of re.
They are allowed providing they are outside the
minimum clearances shown.
The SS850 gas replace is not designed to be built
into bookcases.
AMantel needs to be a min. of 400 mm away
from the edge of the glass
BMax. mantel depth at 400 mm (A) is 250 mm
CSurround needs to be a minimum of 150 mm
away from the edge of the glass
For every 50 mm of added mantel depth there
must be an additional 100 mm of clearance from
the edge of the glass. For example:

FLOORING AND HEARTH MATERIAL SELECTION
The temperature in front of the re (200-350 mm x 400 mm wide) can reach up to 40 °C above ambient, therefore
material selection is important. Some guidelines are detailed below. For example, vinyl planks are often only rated
for ambient temperatures. Consequently, the heater would not be suitable for installation directly on that ooring
type.
A
B
C
D
non-combustible
hearth
Dim. Non-combustible materials or materials
rated to 60 °C or higher above ambient
Materials rated to a maximum
of 50 °C above ambient
Unrated materials, anything up
to 20 °C above ambient
ANo maximum. 150 mm maximum¹ 100 mm maximum¹
BNo minimum 150 mm minimum 300 mm minimum
CNo minimum 400 mm minimum 450 mm minimum
DNo restriction Not suitable for carpets or any heat sensitive materials
1 Refer oating hearth section below
Even if a material is rated above 60 °C it may still be subject to deterioration when exposed to heat cycles.
Always refer to the materials supplier for suitability. The temperatures given assume the heater is operating in a
room temperature of no more than 25 °C. Operation in higher ambient temperatures may result in higher surface
temperatures.
Floating hearth - low rated and unrated ooring materials
For unrated ooring materials, if you use a non-combustible oating hearth, the dimensions of the hearth, minimum
depth and minimum height can be optimised using the following calculations:
Min. hearth depth (A) = 450mm - height of hearth (for 50 °C rated materials it will be 400mm)
Min. hearth height (B) = 450mm - depth of hearth (for 50 °C rated materials it will be 400mm)
Example
For a 200mm deep non-combustible hearth, the calculation for hearth height would be:
450mm - hearth depth (A) (450mm - 200mm = 250mm). The non-combustible hearth height would need to be
250mm minimum.
This would mean the oating hearth dimensions could be 200mm deep and 250mm high.
GENERAL INSTALLATION INFORMATION

Rinnai 9 SS850 IM
TV INSTALLATION
The SS850 has a fan that distributes warm air from the top of the appliance out into the room. As warm air is
dispersed outwards and not directly upwards, installation of a TV may be an option.
The general rule for television installations is that the bottom of the television should be at least 400-450 mm above
the re.
For a TV mounted directly above the re, the mantel must be at least the depth of the TV to deect heat away.
It is the responsibility of the owner to conrm with the TV manufacturer the suitability of such an installation and
any conditions in the TV warranty that may apply to this.
IDEA
Use either a shelf or mantel below the TV or ornament or alternately you can construct a recess
to mount TV or ornaments in. Check the manufacturer's installation instructions for these items
and ensure the recess is suitable.
WARNING
RINNAI DOES NOT TAKE ANY RESPONSIBILITY FOR ANY DAMAGE OCCURRING
TO ANY ITEMS INSTALLED ABOVE AND IN THE VICINITY OF THE HEATER.
CAUTION
INSTALLATION OF TV OR ORNAMENTATION ABOVE THE HEATER
The installation of electrical appliances above and in the vicinity of the heater such as, but not
limited to, TVs, Home Theatre Screens, Speakers, etc., MUST comply with their manufacturer's'
instructions. It is the responsibility of the installer/end-user to check the installation instructions
of these items and to ensure the location is suitable.
This caution also extends to, but is not limited to, ornaments such as: Paintings, Prints,
Photographs, Tapestries, Mirrors, Stu󰀨ed Animals, etc.
Please note the recommended clearances in the diagrams above. Wall surface temperature
may be elevated directly above the appliance and may discolour paint nishes or distort vinyl
coverings. For durability of surfaces consult the relevant manufacturer's specication.

FALSE FIREPLACE INSTALLATION
When installing the Rinnai SS850 into a purpose built false replace, which is not open to the roof
space of the building, cavity vents will need to be added.
Heat lost through the outer skin of the appliance and ue system may not adequately vent. This can
lead to excess heat in the cavity. In some cases the re may overheat and the safety mechanisms
may operate.
Adding two vents of at least 200 cm2 one at oor level and one at ceiling level, will allow adequate
airow in a cavity of approximately 1.2 m wide x 2.4 m high and 0.8 m deep.
IMPORTANT
1. Modify the enclosure:
Ensure the enclosure meets the requirements set out on "Enclosure Requirements" on page 10.
2. Gas and electrical connections:
Prepare gas and electrical connections, refer pages 11-12.
3. Take the Zero Clearance Box (ZCB) and coaxial ue adapter o󰀨 the engine
The Zero Clearance Box and ue adapter come assembled on the engine and need to be taken o󰀨.
(i) Lift and remove the inner frame.
(ii) Remove the two screws holding the outer frame to the re—lift and remove.
(iii) Disconnect the CAT5 cable from the ON/OFF button.
(iv) Remove the screws securing the Zero Clearance Box and slide the engine out
(v) Remove the four screws holding the ue adapter to the Zero Clearance Box and set aside.
4. Install the Zero Clearance Box into the enclosure
Fit the Zero Clearance Box. The base must be at and level. Front ange to be set forward to allow the wall lining
and ange to be ush when nished. Fit the Zero Clearance Box to the framing on the side and top, use packers
to ensure the screws do not deform the panels of the Zero Clearance Box.
5. Install the coaxial ue adapter
Slide the ue adapter up and in place using the support tags on the back of the Zero Clearance Box. Fix in place
using four screws through the air inlet ports.
6. Install ue system:
Install coaxial ue system. Ensure it is self supported.
7. Connect ue to ue adapter
Slide the ue into the spigot of the ue adapter and push down until it is clipped in place.
8. Check engine seals and determine ue length
Ensure the rubber seals tted to the back of the re are in place. Also determine ue length and aeration
plate conguration, refer page 23.
9. Slide engine into the cavity
Slide re into the cavity until the front ange of the re is sitting ush against the ange of the Zero Clearance
Box. When aligned the red exhaust seal goes straight into the hole, and the four holes of the coaxial adapter and
engine line up. Fix the fire to the Zero Clearance Box (four screws) and use outer slots to secure to the enclosure.
Once the fire has been screwed to the zero clearance box, the front face of the frame and the front flange of the
fire should be pulled up hard against each other. There are witness holes in the front flange of the fire to ensure
this happens, refer image on page 24.
It is critical to ensure that the air and flue seals are correctly compressed. If there is a gap present, there may not
be a proper seal and performance could be affected.
10. Complete gas connection
11. Install the burn media and commission
Install the burn media, refer page 25. Ret the glass and the inner and outer frames.
