GENERAL INSTALLATION INFORMATION

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 fire 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 fire.

Hearths
A hearth is not necessary but can be used for decorative purposes. It MUST NOT obscure the front of the fire or obstruct the fire in any way. For more information refer next page.
Floor protection
Heat radiating from the fire may affect the appearance of some materials used for flooring such as vinyl planks, carpet, cork, or timber. To avoid this occurring it is recommended a mat be placed in front.

Carpet MUST NOT be fitted hard up against the fire as it will affect operation

Mantels and surrounds
Combustible mantels and surrounds require clearance from the unit to minimise the risk of fire. They are allowed providing they are outside the minimum clearances shown.
The SS850 gas fireplace is not designed to be built into bookcases.

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 fire (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 flooring type.

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
---|---|---|---
A| No maximum.| 150 mm maximum¹| 100 mm maximum¹
B| No minimum| 150 mm minimum| 300 mm minimum
C| No minimum| 400 mm minimum| 450 mm minimum
D| No restriction| Not suitable for carpets or any heat sensitive materials
1 Refer floating 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 flooring materials
For unrated flooring materials, if you use a non-combustible floating 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 floating hearth dimensions could be 200mm deep and 250mm high.

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 fire.
For a TV mounted directly above the fire, the mantel must be at least the depth of the TV to deflect heat away.
It is the responsibility of the owner to confirm with the TV manufacturer the suitability of such an installation and any conditions in the TV warranty that may apply to this.

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.

RINNAI DOES NOT TAKE ANY RESPONSIBILITY FOR ANY DAMAGE OCCURRING TO ANY ITEMS INSTALLED ABOVE AND IN THE VICINITY OF THE HEATER.
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, Stuffed 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 finishes or distort vinyl coverings. For durability of surfaces consult the relevant manufacturer’s specification.

FRAMING

ENCLOSURE REQUIREMENTS
Masonry Fireplace Installation
The appliance MUST be positioned within the fireplace on a flat level surface.
If the appliance is elevated from the ground within the structure, a base MUST be constructed using suitable material with supporting joists capable of supporting a minimum of 1.5 times the weight of the appliance.

In a masonry fireplace, use a slurry of sand and cement to level the base as required.

False Fireplace Installation
Framework of the installation MUST conform to local building codes. Non- combustible materials need not be used. If the appliance is elevated from the ground within the structure, a base MUST be constructed using suitable material with supporting joists capable of supporting a minimum of 1.5 times the weight of the appliance.

AS/NZS 5601 “GAS INSTALLATIONS” requires that flue components be supported independently of the appliance.

Enclosure Dimensions

| Enclosure Type (All dimensions are minimums and are in mm unless otherwise stated)
---|---
Masonry| False Fireplace| Corner ‡
Model| Height (H)| Width (W)| Depth (D)| Chimney (X)| Height (H)| Width (W)| Depth (D)| Face (A)| Sides (B)| Depth (C)
SS850| 600| 700| 370 | 200 x 200| 655 #| 800 #| 370 | 1550| 1105| 788
| With Inflill Panel|
1030| 740| 370

The co-linear flexible flue MUST NOT come into contact with ANY combustible material.

The larger enclosure dimension for False Fireplace installations allows

fitment of the zero clearance frame. This frame is necessary to provide the required clearances from combustibles.

• When preparing the cavity the minimum depth must be inclusive of the external cladding thickness for false fireplace installations. It is the installers responsibility that adequate clearance be provided between the heater engine and electrical connections.
  ‡ Corner installations use False Fireplace enclosure dimensions and framing specifications.

SUPPLY CONNECTIONS

GAS SUPPLY
Gas pipe sizing MUST consider the gas input to this appliance as well as all other gas appliances in the premises. The gas meter and regulator MUST be specified for the total gas rate.
A suitable sizing chart such as the one in AS/NZS 5601 should be used.
The use of rubber hose for any gas connection to a fixed appliance is NOT authorised by the manufacturer.

Confirm correct gas type (see labels located on top or rear panels). Refer to local gas authority for confirmation of gas type if you are in doubt.

Installation of Consumer Piping
The gas supply (consumer piping), termination is inside the heater and enters through the rear of the appliance.
Refer to page 35 for appliance gas inlet location and other relevant dimensions.
Mark off the location for the vertical centre line ① of the heater enclosure.
To the right of the vertical centre line ①, mark off both the vertical ② and horizontal ③ location for the gas supply penetration (consumer piping). For measurements refer to the Gas Supply Dimension Table below.
The length of the gas supply (consumer piping) termination ④ is measured from the front of the enclosure.

Gas Supply Dimension Table

②| 310mm to the right of the appliance centre-line
③| 35mm from base of enclosure
④| Consumer piping to be terminated 230 mm from the front of enclosure.

Masonry fireplace installations: Gas supply dimension ④ MUST include the thickness of infill panel (when fitted).
A standard Rinnai infill panel adds 2mm to the front of the enclosure.
False fireplace installations: Gas supply dimension ④ MUST include thickness of the cladding used.

Once the consumer piping has been terminated the supplied flexible gas connection ⑤ may then be fitted.

Leak Testing the Connection
With the supplied plug ⑥ inserted into the end of the flexible gas connection, leak test all joints.

Use a soapy solution to test all gas connections. If a leak is present bubbles will form.
When finished remove residue with a rag. Prevent soapy solution from contacting electrical components.

ELECTRICAL SUPPLY

| HAZARDOUS VOLTAGE.
Risk of Electrical Shock.| | Disconnect all sources of supply prior to servicing|
---|---|---|---|---

Socket Outlet
Where a power point is used it MUST be 230 V, rated at 10A and MUST be earthed. This power point MUST NOT be located above the heater. Alternatively the appliance can be direct wired if the power supply is to be concealed.
The heater engine is fitted with a 1.5 m power cord and three pin plug ⑨ which exits the appliance from the rear panel at the lower right when viewed from the rear.

Direct Wired Installations
Alternatively the appliance can be direct wired if so required.

A qualified electrician will need to be consulted where a direct wired installation is required.
Any such installation MUST comply with the requirements of AS/NZS 5601, AS/NZS 3000 and any other relevant local regulations.

False Fireplace Zero Clearance Cable Access
An access flap ⑩ is provided to the LHS of the zero clearance box so installers can reach the power cord after feeding through the hole in the back panel.

Using an existing externally mounted power point
If you already have an existing power point outside the enclosure, you can redirect the power cord through the LHS or RHS of the front panel. With the frame removed redirect the cord and plug (with the grommet), underneath the unit and to the front (left or right).
Remove the pre-punched metal knock-out ⑪ located in the lower left or right edge of the frame, ensuring the grommet is fitted to the metal knock-out. Excess cord may be left in the cavity below the unit—DO NOT coil excess cord.

FLUEING

GENERAL FLUEING GUIDELINES
The following diagrams illustrate the flue installation options that are available for the Rinnai SS850 Heaters. ONLY the genuine Rinnai flue is certified as part of the installation requirements. ONLY an authorised person MUST install, service and remove the Rinnai SS850 and heater and flue system.
Only the flue system components described in this Manual are suitable and MUST be used. ‘DO NOT USE AN UNLINED MASONRY CHIMNEY AS THE FLUE FOR THIS APPLIANCE’.
Components that are not described in that manual, whether manufactured by Rinnai or otherwise, are NOT compatible and MUST NOT be used.
Rinnai appliance warranty conditions may be voided if non Rinnai Flue Components are fitted.
AS/NZS 5601 “GAS INSTALLATIONS” requires that flue components be supported independently of the appliance.

Flueing options for the SS850 depending on the installation:

• False Fireplace – coaxial flueing
• Masonry colinear flueing
  Flexible aluminium flues that come directly off the fire.

Self-supporting flue – False Fireplace
The weight of the flue system should not be supported by the appliance. It should be self-supporting.
Supporting the flue is usually completed during the framing stage with flue supports or straps within the cavity.
Wall straps have been included in the Rinnai coaxial vertical flue kit. Elbow straps are also available as a separate component to prevent excess weight on the flue elbow (if used).
Flue terminal locations
Flue terminals must be compliant with the flue terminal locations shown in AS/NZS 5601.1.
The flue cannot terminate under a floor or in a roof space.

Flue cowl clearance
To ensure products of combustion are cleared, adequate clearance from the building is required.
The flue cowl should have a 500 mm clearance from any part of the building. This also applies to steeped and pitched roofs where the flue cowl should be 500 mm clear of the ridge line.
An adequate flow of fresh air must exist around the flue cowl following installation.
Minimum clearances are shown in AS/NS 5601.1

INSTALLATION

FALSE FIREPLACE INSTALLATION
When installing the Rinnai SS850 into a purpose built false fireplace, 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 flue system may not adequately vent. This can lead to excess heat in the cavity. In some cases the fire may overheat and the safety mechanisms may operate.
Adding two vents of at least 200 cm2 one at floor level and one at ceiling level, will allow adequate airflow in a cavity of approximately 1.2 m wide x 2.4 m high and 0.8 m deep.

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 flue adapter off the engine
   The Zero Clearance Box and flue adapter come assembled on the engine and need to be taken off.
   (i) Lift and remove the inner frame.
   (ii) Remove the two screws holding the outer frame to the fire—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 flue 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 flat and level. Front flange to be set forward to allow the wall lining and flange to be flush when finished. 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 flue adapter
   Slide the flue 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 flue system:
   Install coaxial flue system. Ensure it is self supported.

7. Connect flue to flue adapter
   Slide the flue into the spigot of the flue adapter and push down until it is clipped in place.

8. Check engine seals and determine flue length
   Ensure the rubber seals fitted to the back of the fire are in place. Also determine flue length and aeration plate configuration, refer page 23.

9. Slide engine into the cavity
   Slide fire into the cavity until the front flange of the fire is sitting flush against the flange 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

10. 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.

11. Complete gas connection

12. Install the burn media and commission
    Install the burn media, refer page 25. Refit the glass and the inner and outer frames.

   Stretch out the flexi to the required length and attach to the flue terminal using the clamps provided. Fix flue terminal in place, allow enough flue in the cavity to fix the flue adapter.

6. Connect flexi flues to the colinear flue adapter
   Place the flue adapter in the cavity, it can be on the floor while attaching the flues. Attach the air intake flue over the spigot, place the flue clamp over the flue and tighten. DO NOT overtighten as this will crush and damage the flue. Drill through the pre-punched holes either side of the clamp, and into the flexi flue spigot. Secure using the stainless steel self tapping screws provided, ensuring connection will stop movement or dislodgement of the flue. Slide the exhaust flue into the spigot and push down until it is clipped in place

7. Secure flue adapter to the adapter frame
   Lift adapter box into place and rest in support tags in the back panel. Fit to the back panel using four screws through the air inlet ports.

8. Check engine seals and determine flue length
   Ensure the rubber seals fitted to the back of the fire are in place. Also determine flue length and aeration plate configuration, refer page 23.
   9. Slide engine into the cavity
   Slide fire into the cavity until the front flange of the fire is sitting flush against the flanges of the support panels. When properly aligned the red exhaust seal goes straight into the hole, and the four holes of the adapter frame and engine line up. Fix the fire to the adapter frame (four screws) and use the outer slots to fix the fire to the enclosure. Once the fire has been screwed to the adapter frame, 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 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. Refit the glass and the inner and outer frames. If using an infill panel, refer separate instructions.

AERATION PLATES
The SS850 comes with two aeration plates that are factory fitted, in a position for flues between 3-5.5 m, refer image below. There are a further two aeration plates supplied in the accessory pack (for flues 5.6-8 m).
To control flame lift and efficiency on long flues (anything over 3 m) it’s important the aeration plates are configured correctly. Refer chart below.
To maintain balance within the combustion chamber, it is important to fit the plates equally to both sides. The chart below shows the plates required for any given flue length. Fitting more plates than shown may have a detrimental effect on startup performance, especially in very cold areas.
If the flue length is less than 3 m the factory fitted aeration plates need to be removed.

FIRE TO FLANGE CONNECTION
The below installation step is common to masonry and false fireplace installations. It is CRITICAL to the safe operation of the fire.

Once the fire has been screwed to the zero clearance box or masonry adapter frame, 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.
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.

BURNER MEDIA INSTALLATION

BURNER MEDIA PLACEMENT
The granule pack and log set, consisting of five logs, comes packaged inside the appliance. Use extreme care when handling the logs, they are fragile and will damage easily. The unit must never be used with broken logs or other burn media.
Experience has shown that the majority of performance problems are caused by burn media being installed incorrectly. Incorrect placement can create carbon build-up and affect performance. Please take the time to read and follow these instructions as malfunctioning due to incorrect placement is not covered by warranty.
The granules as well as being added to create a more realistic log effect (they diffuse the gas flames) also assist in soot prevention and are CRITICAL to the correct operation of the fire. Never pour the granules directly from the pack as dust particles and the granules may block the burner ports.

During the initial burning in period of approximately 2 hours, some minor smoke and smell may be experienced. During this period the heater should be operated on High and the space being heated should be well ventilated. It may take up to 20 minutes of operation for the logs to achieve their full flame pattern and glow.
Malfunctions due to incorrect burn media placement are NOT covered by warranty.
The appliance MUST NEVER be used with other burn media or burn media that is damaged.
