1. WARNINGS
THIS APPLIANCE SHOULD BE MAINTAINED AND OPERATED AT ALL
TIMES IN ACCORDANCE WITH THESE INSTRUCTIONS.
The Viking RU is tested to N.Z. Standards AS/NZS 2918:2001.
If this heater is incorrectly installed a house fire may result. For your safety follow the
installation instructions carefully.
Do NOT connect the heater to a chimney serving another appliance.
Although the exterior of the heater may appear cool, contact with the unit may cause
burns, warn children and others of the possibility of injury should they touch the
heater.
Do NOT dry clothing or unseasoned wood directly in contact with the heater.
Keep all household combustible materials at least 600mm away from front of the
heater. This includes clothing, furniture, wood, newspaper, plastic, matches, etc.
DO NOT USE FLAMMABLE LIQUIDS OR AEROSOLS IN THE VICINITY
OF THIS APPLIANCE WHEN IT IS OPERATING.
Use caution when reloading with fuel. Do NOT attempt to load fuel into the heater
when the fire inside the stove is at or near its peak.
Do NOT burn large quantities of paper or combustible material that would create an
extremely hot/quick fire.
Do NOT burn highly coloured paper or brochures (junk mail).
USE ONLY DRY WOOD. AVOID BURNING WET OR GREEN WOOD.
THE USE OF SOME TYPES OF PRESERVATIVE TREATED WOOD AS A FUEL
CAN BE HAZARDOUS.
TIMBER TREATED WITH COPPER CHROMIUM AND ARSENIC TYPE
PRESERVATIVES WILL LEAVE TOXIC RESIDUES IN THE ASH, FIREBOX OR
WITHIN THE FLUE; TIMBER OFFCUTS FROM BUILDING CONSTRUCTION
WILL OFTEN CONTAIN BORIC SALTS. THE COMBUSTION OF THIS
MATERIAL OVER PROLONGED PERIODS CAN PRODUCE ADVERSE
EFFECTS ON REFACTORY LINING IN SOLID FUEL APPLIANCES. EMISSION
OF POISONOUS GASES CAN ALSO BE EXPERIENCED WITH THE BURNING
OF TREATED WOOD.
Driftwood with salt content will also cause rapid deterioration of the heater and should
not be used.

IN ACCORDANCE WITH AS/NZ 2918 AND THE APPROPRIATE
REQUIREMENTS OF THE RELEVANT BUILDING CODE OR CODES.
ANY MODIFICATION OF THE APPLIANCE THAT HAS NOT BEEN
APPROVED IN WRITING BY THE TESTING AUTHORITY IS
CONSIDERED
TO BE IN BREACH OF THE APPROVAL GRANTED FOR COMPLIANCE

Any variation from these installation instructions or any doubt about them must be
checked against the requirements of the Standards.
Please leave this manual with the owner when installation is complete.
3. FLOOR PROTECTOR REQUIREMENTS
The heater should always be installed on top of its base due to high temperatures
sustained over long periods. The base must be anchored to both the floor protector and
the floor for seismic restraint. Anchor points are provided in the base.
If the heater is installed on or within 500mm of a heat sensitive floor, then an ash
floor protector using a minimum of 6mm thick tiles will be required. This
floor protector shall extend under the appliance and not less than 300mm beyond the
front of the fuel loading or ash removal openings. The width of the floor protector
shall be not less than the width of the appliance, and shall extend not less than 200mm
from each side of the fuel loading or ash removal openings unless it forms an abutment
with a wall or heat shield at a lesser distance.
Where the floor protector consists of a number of components, it shall include a
continuous layer of heat-resistant material extending under the appliance to the
perimeter of the floor protector. All joints shall be fixed to prevent accidental
separation, and shall be sealed to prevent any spilt ash or embers contacting any heat
sensitive material.

5. ASSEMBLY INSTRUCTIONS
1. Remove all outer packaging and timber.
2. Remove slotted steel top plates from rear of heater and cast iron top
plates from inside the heater and carefully set aside, taking care not to
scratch or damage the paint finishes.
3. Position unit onto floor protector ensuring it complies with the
clearances as shown in section 4 on page 5.
DO NOT ATTEMPT TO LIFT THE HEATER BY THE GRANITE
ASHLIP.
4. Plumb in the wetback in accordance with accepted plumbing practises
refer to section 6 page 7. Ensure the wetback is not pushed down or
comes into contact with the baffle bricks or flue gas deflectors. This will
cause premature wear to the wetback and will not be covered by the
manufacturer’s warranty.
5. Install the rear cast iron plate and then the front cast iron plate onto the
rope seals around the top of the firebox and ensure they are bedded down
well. Lifting lugs are positioned onto the sides of the casting, taking care
not to catch fingers under the plates.
6. Assemble and install the flue as per instructions (page 8 & 9).
7. A flue shield must be fitted; the minimum requirement is for a single
skin, semi-circular, stainless steel flue shield with a reflective inner
surface 1200mm high. This should be installed so that the bottom edge of
the flue shield is 20mm from the top surface of the heater and spaced off
the flue pipe by approximately 35mm.
8. Secure both fire and floor protector to floor by using appropriate
fastenings through the holes provided in the rear of the base plate. This is
a New Zealand Standard 2918 requirement due to NZ being earthquake
prone.
9. Carefully position the main slotted steel painted top panel onto the
heater, there are locating lugs on the underside that fit into the indents on
the cast iron tops that ensure it is correctly positioned. Slide in the rear
infill top plate behind the flue and the curved top plate locates into the lugs
onto the back edge.
10. Fit door knob with spacer
as per drawing shown herewith. -

APPROPRIATE REQUIREMENTS OF THE RELEVANT BUILDING CODE
OR CODES.
For best performance apply the following rules:
1. Keep it simple with the shortest and straightest possible pipe run.
2. The heater should be within 6 metres of the hot water cylinder, the closer the better.
3. The flow pipe from the heater to the cylinder must rise – the cylinder should be at
least 300 mm above the water-booster outlet.
4. Use only 25mm supply and return pipes.
5. Where possible the pipes should be insulated.
WARNING:
Care must be taken to protect the wetback coil and associated pipework if being
installed in a hard/corrosive water area. Damage caused to the Wetback coil if fitted in
a hard/corrosive water area will not be covered under the manufacturer’s warranty.

7. FREESTANDING FLUE SYSTEM
INSTALLATION INSTRUCTIONS
1. Position heater on floor protector ensuring all heater
clearances are correct as per clearances on page 5.
2. Once the location is confirmed, the appliance and floor
protector shall be fixed to the floor itself (refer to
page 6 & 7 .
3. Extend a plumb line from the centre of the fire flue pipe
spigot to the ceiling. Mark position on ceiling and roof.
4. Trim hole and nog as required ensuring that a 25mm
safe clearance between combustible materials and flue
components is maintained. Fix with non combustible
spacers and screws or clouts on all four sides.
5. Cut and frame (when required an opening in the roof,
position the outer casing through the roof until it is flush
with the under side of the ceiling, making sure as with
the ceiling there is a 25mm safe clearance between
non-combustible materials and the flue components.
Fix as in step 4.
6. Fix appropriate flashing around outer casing to the
roof to ensure a weatherproof seal.
7. Assemble flue pipe sections ensuring all seams are in
line, the assembly is straight and crimped. Ends are
pointing downwards. Fix each joint with three stainless
rivets or self-tapping screws.
8. Place ceiling plate with folded edges upwards over
heater spigot.
9. Position the flue pipe into the heater spigot. The flue
pipe can either lowered from the top as a single unit or
fed up from the room a length at a time, ensuring that
all joints are fixed properly.
10. Slide the inner casing into place, between the outer casing
and the flue pipe.
11. The flue pipe must extend 200mm above the outer casing.
Note: Extra lengths of flue pipe, inner and outer casing
may be required to achieve the minimum clearance from
the roof.
12. Slide top spreader over flue pipe down into outer and inner
casing and tighten.
13. Slide cowl over flue pipe until it rests on spreader. Secure
with rivets or self-tapping screws.
14. Fit rainhat. Do not fasten as it must be removable for flue
