POINTS TO CONSIDER PRIOR TO INSTALLATION
Prior to construction and installation
IMORTANT NOTES:
Install to AS/NZS 2918:2001.
Install to manufacture’s specifications.
All new installations require a permit.
For special requirements concerning materials (timber mantle and surrounds) within close proximity of Warmington products, please contact your
local Warmington technical consultant or designated installer.
Stage 1:
Frame construction procedure by builder.
Mark out flue centre on floor.
Mark out heat cell clearance requirements.
Construct plinth only, to required height.*
Stage 2:
Install procedure by certified “Warmington Installer” or see www.homeheat.co.nz go to ”members” & follow instructions. For an
NZHHA certified SFAIT installer.
Fit fire to plinth.
Fit adaptor to firebox.
Construct Autoclaved Concrete (ACC) enclosure around the firebox.
Fit flue system.
Fit cowl and flashing system.
Stage 3:
Finishing procedure by builder.
Construct hearth to required thickness.*
Finish Autoclaved Concrete (ACC) enclosure and hearth to customers requirements (e.g. paint/tiles).
Close in Autoclaved Concrete (ACC) enclose and chimney chase (if in timber alcove).
* Note: A certified installer can also install hearth and plinth.
Ensure that the Warmington and flue system is swept annually or more frequently if required. To sweep flue and firebox:
Cover front of fire with sheets, or keep door closed during sweeping.
Remove cowl from top of chimney.
Sweep from the top, down the flue.
Remove all soot and ash.
Ensure cowl and bird protection is clean and replaced.
Visually inspect fireplace and flue system.
INSTALLATION ORDER OF OPERATIONS installation is not provided
Location of the fire.
Open fires are better located at one end of a room or area, as they project the heat away from their opening.
The topography of the land.
The slope and position of the land in relation to the home has a bearing on how the wind will interact with the fire and flue system. Care needs to be taken to ensure that the flue
termination is in the correct position to maximise performance.
The Prevailing wind.
Care needs to be taken to ensure that the flue termination is in the correct position as wind and gusts that hits the flue and cowl system may overcome the cowl and draft back down
the flue into the home. This can be a combination of downdraft and high pressure.
Hearth and plinth:
The height of the hearth off the floor. The finishing that is to be used on the hearth is to be allowed for at the design stage.
Note: ensure air intake at base of firebox is not blocked or restricted.
Positioning of the flue system:
There is a maximum distance that an offset flue can be installed. Reference to AS/NZS 2918:2001.
Flue and fire clearance:
To be maintained to the manufactures instructions and/or comply with appropriate standards and building codes.
Pressure differential, venting and external air into the building
:
All fires need air to burn and draw correctly, Kitchen Fans, Air Conditioning units, High Wind Zones, Naturally forming Draft spaces, can all have an effect on the pressure difference
from inside the building to the outside. A lower pressure in the building may induce a draft down the flue system and back into the building causing the fire to smoke or spill into the
building.
Care needs to be taken at the design and installation stage to adequately vent the building, or some mechanical system to ensure that there is always a neutral or
positive pressure at the fireplace and a negative pressure at the flue outlet.
This will ensure that the draft in the flue system is always to the outside.
Wind Noise:
You may encounter wind noise in some installations. It is recommended
to use an enclosed chase with a chimney pot to help reduce noise. There will always be some noise from the
flue systems of all fireplaces.
Installation Notes:
Due to the expansion and contraction of metal fireplaces a 3mm gap between the flange and the finished surround should be maintained.
