Clearances
The clearances listed below, measured from the edge of the inner glass, are
minimum clearances unless otherwise stated.
While the heater is operating
The appliance must not be installed where
curtains or other combustible materials could
come into contact with the heater. The 1000 mm
clearance above is the clearance to the ceiling.
The 300 mm side clearance includes side walls.
Wall surface above the heater
The temperature of the wall surface directly
above the appliance may get warm and
discolour paint finishes or distort vinyl
wall coverings. For durability of surfaces,
please contact the manufacturer for their
specification.
Floor protection
Heat emanating from this fire may over time
affect the appearance of some materials
used for flooring, such as, carpet, vinyl, cork
or timber. This may be amplified if the air
contains cooking vapours or cigarette smoke.
To avoid this occurring, it is recommended
that a mat be placed in front of this appliance.
Mantels and surrounds
Combustible mantels and surrounds require
clearance from the unit to minimise the
risk of fire. Mantels and surrounds, made
of combustible materials such as wood,
are allowed providing they are outside the
minimum clearances shown.
Hearths
A hearth is not necessary but can be used
for decorative purposes or protection of
sensitive flooring if required. A hearth must
not obscure the front of the fire.
TV installation above the fireplace
Installing a TV directly above the Compact 2
is not recommended due to the heat being
emitted directly above the fire and also heat
being generated from the flue components.

Electrical connection
The Compact 2 is fitted with a 1.5 m power
cord. The electrical connection can exit the
appliance from the lower left or right hand
side, or from the rear.
Direct wired installations
A qualified electrician will need to
be consulted where a direct wired
installation is required.
Installation must comply with the
requirements of AS/NZS 5601.1, AS/NZS 3000
and any other relevant local regulations.
Using existing externally mounted power
points on inbuilt installations
If there is an existing wall plug located outside
of the intended fireplace or enclosure you can
redirect the power cord and plug assembly
through the front panel. With the frame
assembly removed, redirect the cord and plug
assembly (with grommet) underneath the
heater to the front of the unit—either left or
right hand side.
Carefully remove the pre-punched metal
knock-out section on either the left or right
hand side of the frame assembly. Refit the
cord and plug assembly to the frame assembly
ensuring the grommet is fitted to the sheet
metal. Excess cord may be left in the cavity
BELOW the unit. DO NOT coil the excess cord.
IMPORTANT

Flueing options
The below options detail the most common types of flue installations. If you have an
installation that varies from those below, please contact Rinnai.
Flue component
- Flue cowl (R1760-2)
Masonry without a flexiliner flue
For installations into a masonry cavity where
the chimney has been swept, checked for
soundness and ability to achieve a good draw.
Masonry with flexiliner flue
For installations into a masonry cavity where
a Rinnai aluminium flue is required to ensure
optimum performance of the appliance.
Flue components
- Flexiliner flue kit (R1758) 3.6 m
If flueing exceeds 3.6 m add:
- Flexiliner flue extension (R1761)
Inbuilt mock chimney direct and offset
For installations into a combustible opening
with a zero clearance box, where the flue runs
vertically in-wall.
A: Flue component
- Zero clearance flue kit (R1762Z)
B: Flue components
- Zero clearance flue kit (R1762Z)
- 45 ° bend kit x 2 (R1764)
If flueing exceeds 3.6 m add the
galvanised or stainless steel flue
extension (R1763Z, R1763SS).
Inbuilt mock chimney offset wall penetration
For installations into a combustible opening
with a zero clearance box. Flue runs in-wall,
then penetrates the building before terminating
vertically.
Typically used in multi-storey dwellings where
the fire is installed on the ground floor.
Flue components
- Zero clearance flue kit (R1762Z)
- Wall penetration kit (R1766)
If flueing exceeds 3.6 m add the
galvanised or stainless steel flue
extension (R1763Z, R1763SS).
Masonry installations
Rinnai recommends the use of a flexiliner flue (Ø 100 mm) as it ensures optimum performance of the
appliance. Installation without a flexiliner flue is permitted as long as the chimney has been swept,
checked for soundness and ability to achieve a good draw.
Mock chimney flueing
A Rinnai zero clearance box and flue kit are mandatory for installations into a combustible opening.
Minimum flue length - 3.6 m
This is required to ensure adequate draw and to prevent spill-back of combustion products, which can
cause the safety sensors to shut down the fire. The minimum flue length before any bends or offsets is
1.2 m (or one length of flue). The minimum vertical flue length is 3.6 m or three lengths of flue.
Maximum flue length - 8 m
Rinnai recommends a maximum flue length of 8m with a maximum of two 45 ° bends.

Compact 2 Installation Guide: 11817-D 04-15 | 11
Flueing guidelines
Inner flue: Clearance to combustibles
Clearance from the inner flue to a combustible material must be greater than 25 mm.
Flue cowl clearance
To ensure products of combustion are cleared, adequate clearance for 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 which should be clear of the ridge line as shown. Lesser clearances
may provide perfectly adequate flue systems depending on the installation. Minimum
clearances are shown in AS/NZS 5601.1.
Flue terminal locations
Must be compliant with ‘Clearances Required for Flue Terminals’ from AS/NZS 5601.1. The flue is
not to terminate under floors or in a roof space.
Self-supporting flue
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.
Shared flues
Gas appliances must not be connected to a chimney or flue serving a separate fuel burning
appliance.
Flashings to to the top of the chimney structure do not form part of the flue kit and
must be specified.

12 | Compact 2 Installation Guide: 11817-D 04-15
Masonry ue installations
There are two types of masonry flue installations; open chimney and lined chimney. An open
chimney uses the natural draft properties of a sound chimney, an approved chimney plate and
cowl to provide flueing for the heater. A lined chimney installation is used when the existing
chimney condition is inadequate for an open chimney installation and uses a Rinnai flexiliner flue
to provide flueing for the heater.
Check dimensions of opening
Ensure opening is within the range provided (p. 5), and if necessary bring them to the required
dimensions. Also check chimney height as inadequate height can affect product performance.
Some installations may require the chimney height to be extended to reduce down drafts. Also
check there are no obstructions.
Provide a solid, flat, and sealed base, otherwise noise and vibration may result. Sealed means no
holes or openings in the fireplace.
Some criteria for checking chimney soundness
Rinnai strongly recommends the use of a Rinnai flexiliner flue system. Failure to meet this criteria
may result in an unsafe situation. Installation without a flexiliner flue is permissible as long as the
chimney is swept, checked for soundness and ability to achieve a good draw. Some criteria for
checking soundness:
- All loose/broken bricks must be replaced or repaired ensuring the chimney is of sound
construction and does not leak.
- Chimney must be swept clean and be free from soot and creosote that may have built up if
previously used for a solid fuel fire.
- Any damper plate must be fixed in an open position or removed.
- Any underfloor air supply to the fireplace must be completely sealed to prevent secondary
air draw.

Completing the heater installation
1. Remove combustion
chamber glass
Loosen, but do not remove the
bottom two retaining screws.
While supporting the
combustion chamber glass
panel, completely unscrew
and remove the two remaining
screws and clamp. Lift the
combustion chamber glass
panel and place aside.
2. Unpack log set and granules
Carefully unpack the log set
and inspect for damage. If
any damage is evident, do not
continue with the installation.
The satchel containing the
burner granules is taped to the
outside of the foam packing
that contains the log set.
3. Install log set and granules
Use extreme care when
handling the log set as it is
fragile and will damage easily.
To position correctly, hold
the log set at approximately
45 ° directly in front of the
combustion chamber. Maintain
this angle and place the front
feet of the log set behind the
unpainted inner horizontal steel
lip of the combustion chamber.
To set the log set into the final
position, rotate the back of the
log set down, using the location
of the front feet as pivot points,
until it is sitting flat on the rear
burner.
Check the correct position of
the log set before installing the
granules. Ensure the log set is
firmly seated in the centre of
the combustion chamber and
not touching the side walls, and
that the ports are clear of any
debris that may have occurred
during installation.
Carefully place (do not pour)
the granules over and around
the front burner ports. It is
beneficial that the gas jet is
diffused by the granules. This
will reduce any candling effect
of the flame and enhance the
realistic log-burning look of the
heater.
Do not force, or block
the burner ports with the
granules and do not place
any granules on the rear
burner.
4. Replace combustion
chamber glass and turn on
electrical supply
6. Check burner pressures
Turn gas supply on, and refer to
the data plate on the appliance
for the correct gas pressure
settings.
Remove the pressure test point
screw and attach a manometer
to the test point situated on the
front of the injector block.
Light the heater, select the
high heat setting, and check
the pressure. If adjustments
are necessary, the regulator is
situated on the front of the gas
control.
After checking pressures,
turn the unit off, remove
manometer, and replace test
point screw.
Turn the heater on and off a few
times to check ignition. When
you are satisfied that the heater
is working check the flame
pattern, refer p. 20.
7. Attach frame assembly
Re-attach the gas/electrical
plate. DO NOT do this if you are
installing the traditional frame
as this already has the plate
included.
Traditional frame - gas/electrical
plate not required
Standard frame - gas/electrical plate
required
Carefully pick up the frame
assembly* and position the top
fold over the mounting tabs and
gently push the lower edge of
the frame down over the unit.
Fit and tighten the frame to the
unit using two screws for the
standard frame or three screws
for the traditional frame.
* Standard frame: Do not tilt on its
edge as the glass may slide out off the
standoff posts.
8. Complete the installation
checklist
Complete the installation and
commissioning checklist in the
customer operation guide, and
make sure you leave the guide
with the customer.
Explain to the customer about
the use and care of the heater,
and ensure they understand the
instructions and operation of
the appliance.

Flame pattern
It may take approximately two hours of operation for the logs to achieve their
full flame pattern and glow. During the initial burning in period, some smoke and
smell may be experienced. The appliance should run on the high setting in a well
ventilated room until these dissipate. It is important to check the flame pattern
during this time.
Abnormal flame pattern
Abnormal flame performance
and/or pattern can indicate a
problem with the fire, such as
blocked gas injectors, or log set
(burn media) has shifted from
when the fire was first installed.
There are some warning signs
that could indicate a problem.
- Unusual smell from the
appliance
- Continued difficulty or delay
in establishing a flame
- Flame appears very short or
very long
- Flame only burns part way
across the burner
- Severe soot building up on
the inside of the glass
Important
It is the responsibility of the
installer to check that under
normal conditions of the
appliance, all flue gases are
exhausted to the outside
atmosphere, and that there is
no spillage of combustion gases
into the room.
If the appliance cannot be made
to perform correctly please
contact Rinnai.
