Know what you want for your fire but not sure how to get it done? Don’t worry, we can help you make your plans into reality. Gas Fires NZ specialises in the design of any gas fire system you may have in mind.
When designing a gas system, there is a lot that needs to be kept in mind. Location in the home, space, where to mount the bottles are all things that need to be considered when designing a gas system. There are certain regulations that need to be met for some of these things such as bottle placement. An appliance must be installed to meet the safety requirements of NZS 5262 “gas appliance safety” and 5601 part 1 and 2. This is something that a certified gas fitter will know and will ensure is done. As well as this, you need to know your requirements of the gas system to be able to select adequate components from sizes of gas bottles to the appliance (in the case the gas fire) that will be meet your needs.
We at Gas Fires NZ are fully certified gas fitters who can help you design you ultimate gas fire. We can help you to select the gas fire that best suits your need and budget, help you complete the design and make sure that the installation is done to the highest standard and meets all regulations. We are your one stop gas fire shop!
Efficiency is also another factor that should be considered when designing a gas fire. You don’t want to be wasting money for no reason, especially since you already installing a new system and when more efficient system may be available. The size of the area you wish to heat and how hot you want it to be will dictate the size of the system and the fire should be selected accordingly. Why pay for bigger than what you need?
Things to consider when selecting a gas fire or heater:
The volume of the area you want to heat (including ceiling height).
The climate zone of the area you live in.
Features of your home including wall & ceiling insulation, window coverings and carpeting.
The kW output of the gas heater.
Common mistakes to avoid when selecting a gas fire or heater:
- Choosing the incorrect fuel type for your needs
- Selecting the wrong type of gas heater for your home
- Getting the wrong size gas heater
- Paying too much for the gas heater

Flues are a very important consideration which must be made for any gas appliance (excluding a few flueless appliances). But first, what is a flue?
A flue is duct (or chimney) for gas appliances that produce larger amounts of combustion gases that need to be discharged out of the building. There are several different types of flue including:
- Natural draught flues
- Down draught diverters
- Balanced flues
- Fan assisted and fan diluted flues
The flue can be a very important factor in placement of your fire as flues need to be positioned in certain areas to comply with installation standards. The flue terminal (or cowl) needs to be designed to offer the least air resistance to outflowing gases and much resist down-draughts, rain, wind and airborne debris. The flue cowl terminal must be installed where it can function properly. What can affect a flue’s operation?
Overhanging or adjacent structures. These may cause a pocket of still air which a natural draught flue may not be able to overcome. This results in combustion spilling back into the room and incomplete combustion will occur because the burner flame will be smothered. They can also cause wind eddies to blow into the flue, which causes a down-draught.
Trees. Often overlooked, trees can cause the same issues as the aforementioned structures. It must be taken into account where trees are located before installing a flue terminal.
Steep Roofs. Unfavourable wind conditions combines with steep roofs can cause turbulence, resulting in down-draught in the flue. One way to combat this is to install the terminal higher from the roof’s surface, reducing the amount of turbulence at the terminal. Only in some extreme cases will the flue have to be relocated or installed elsewhere.
Other Flues. Other flue terminals and vents can also cause a disruption as they will be discharging their gases and could result in their output being drawn into yours.
Other Components To Consider
There are several other components to a gas system that also need to be considered in the design.
There are three kinds of control systems for appliances which are:
- Mechanical control systems – These control gas supply directly, or indirectly by means of a flame failure device or relay valve.
- Electrical control systems – These control the gas supply indirectly using a solenoid valve.
- Electronic control systems – These use electronic circuits to control electrical equipment, which in turn controls the gas supply.
