What are the different flue options available on Rinnai Fires and what do they mean?
Rinnai offers three different types of flue (Natural draft, Power flue or Direct vent). The type of flue will determine where the fire can be installed.
Often referred to as a standard flue system. This type of flue draws the air for combustion (to run the fire) from the room and then expels combusted gases to the outside via a vertical flue. As the air for combustion is being drawn from the room there is a requirement for adequate ventilation (requirement to replenish the air). Adequate ventilation must be calculated and provided by the gasfitter, as per AS/NZS 5601.1
The flue must terminate vertically through the roof.
A Rinnai power flue system has a sealed combustion chamber with a fan, that draws air for combustion from the outside (through the outer flue) and expels combusted gases to the outside (through the inner flue). This type of system does not take oxygen or heated air from the room.
Rinnai appliances flued by a power flue are approved by the sensitive choice programme of the Asthma foundation as they maintain air quality for a healthy breathing environment.
Power flues are smaller in size, can have a number of bends, can be flued down and-out, sideways, and can terminate horizontally or vertically. This means power flued appliances can be installed in almost any living or working space, including bedrooms.
A direct vent flue system, like the power flue, also has a sealed combustion chamber, but differs by using natural draft to draw air (from the outside) and expel combusted gases (to the outside). Like the power flue, the air quality of the room being heated is maintained.
Direct vent flues, as they use natural draft to move air and gases through the flue have a larger flue size (compared to the power flue).
The flue can terminate horizontally or vertically.
What are the size and the length of the flue parts for Rinnai Fires?
The size and length of the flue parts will vary depending on the fire specified. Refer to the Specification Guide for Gas fireplaces for detailed information.
How many bends can a flue have?
This depends on the fire being specified.
|Evolve/Arriva:||can have a maximum of 3 bends|
|Symmetry:||with a vertical termination, a maximum of 2 45° bends
with a vertical termination, a maximum of 2 90° bends
with a horizontal terminal, a maximum of 1 90° bend
|Neo/Compact 2:||can have a maximum number of 2 45° bends|
How does the Symmetry Heat Transfer system work?
The heat transfer system allows you the ability to warm up to two additional rooms using the heat transfer system via either a floor vent or ceiling outlet. The heat transfer system doesn’t provide the ability to select which room to heat – it will warm the rooms that have been connected with the heat transfer system.
Can the fires go in to existing masonry installs?
Yes. The Neo and the Compact 2 are designed to go into existing masonry. The size of the existing cavity will determine which fire you can install.
Are all the fires efficient?
The Rinnai fire range are efficient heaters with a star rating of between 4.1-5.7 stars (excluding the Compact 2). The number of stars is a visual representation of the annual energy consumption and is great for a quick reference. The more stars a fire has, the more energy efficient it is.
Gas is both fast and reliable. Natural gas is available to many areas of NZ but in areas where it isn’t available, it can be delivered to your doorstep in LPG bottles. It’s convenient and like natural gas, delivers fast efficient heat.
Gas is an energy source New Zealanders can rely on because there is a lot of it right on our coastline. Experts believe there is enough to keep us going for at least eight generations.
Can I specify a Rinnai gas fire into an apartment?
Yes. The following fires can be installed in an apartment:
It is important to note that the flue termination point doesn’t go outside of the boundaries for the building consent.
Where do I find information on the fire dimensions?
This information can be found by looking in the specification guide.
Where are Rinnai products developed and manufactured?
Rinnai fires are designed and made in New Zealand. We make our fires for New Zealanders and ensure that they work optimally in New Zealand’s environment.
Do you have a product technical statement available for your fires?
Yes, we have developed product technical statements (PTS) for our current range of gas fires. These can be found as a PDF document within the technical tab for each fire.
A PTS is a way to show how a product or system is fit for purpose for use in New Zealand, and to demonstrate compliance with the NZ Building Code (Building Amendment Act 2013: 14G)
How many gas fires can you install in one house?
There is no limit to the number of gas fires that you can install in a house. However, the installer and gas supplier will need to calculate the MJ load on the gas supply and calculate the pipe sizing required and the necessary meter requirements. On natural gas, a commercial meter may be required and on LPG more than 2 LPG cylinders may be required.
What does the Architect portal provide me with?
The Rinnai architect portal is an easy way to access light-weight CAD/BIM data for a number of Rinnai products for use in design specifications. The information is delivered in formats that support the latest tools being utilised by specifiers and the building industry.
Use the architect portal to view all the product files in one place, or if you know what you’re specifying, access the pre-filtered files in the CAD/BIM tab of each Rinnai product on the Rinnai website.
