You’ve been searching through our range and you have found a fire that fits your requirements and budget and you are ready to buy. Great! But, wait, who’s going to put it in?
Gas fire installation is a high specialised job due to the gas work involved. A registered gas fitter must be used to install your gas fire, and the installation needs to meet certain requirements. But do not worry, we can help.
We at Gas Fires are specialists in gas installation and are fully qualified and certified in New Zealand. Having helped many people get the gas fire they wanted, we can help you too. All of the fires on our website come with the option of installation, and will be fully gas certified upon completion.
Things to bear in mind with a gas fire installation
- Freestanding gas fires need a metal flue installed through the through the roof.
- If you do not yet have gas set up at your home yet, the installer will need to install a gas regulator, the gas bottle connection and piping.
- For inbuilt fires, you will need to build a false wall enclosure for the fireplace and flue.
Upon installation, all gas appliances need to be commissioned to ensure the installation meets standards and everything has been done right. What does this involve?
During a commissioning, the following checks will be done:
- Visual check: purging and lighting of the appliance to check for the correct flame. Gas/air mixture will be adjusted as necessary.
- Pressure check: A manometer will be connected to the appliance pressure point to check the working pressure when the appliance is fully on. The pressure regulator will be adjusted as necessary to ensure correct operating pressure.
- Leak test: Once the manomter is removed and the test screw reinstalled, the appliance will be tested for gas leaks.
- Appliance Operation: The appliance will be turned off and on several times as well as up and down (if modulating type) to ensure correct operation and smooth igniting.
- Gas-rate check: The rate at which the appliance uses gas will be checked against the appliance specifications and adjusted to ensure the appliance is correctly operating.
Why gas-rate an appliance?
Gas rating an appliance involves checking the hourly gas rate to ensure that the heat input is within the correct amount for which the appliance is designed. Too little heat will lower the efficiency and heat output, whereas too much heat will cause high gas accounts as well as causing the appliance to overheat.
Gas rating an appliance is done by setting the appliance at the correct working pressure, turning off all other gas appliances, then timing one complete revolution of the test dial with the appliance on full. Based on how much gas passed through the appliance, the gas rate is calculated and adjusted accordingly.
