Sean phoned to confirm what time he would be on-site to remove and install the new Rheem Hot water cylinder. He arrived on time and set about removing the old cylinder and installing the new . He worked non stop with the installation which was completed to a very high standard. He cleaned up any mess and after loading the truck he ran through the install showing me what did what and if I had any problems to let the company know. It was good to see a conscientious tradesman at work.Thanks Sean, a great job

Josh and Brandon arrived on site and explained what they were going to do. Took minimal time to do the job and explained the warranty and maintenance procedures before they left. They gave me peace of mind by stating they would return within the 10 year warranty period if any trouble occurred with the system. I found both boys to be polite and courteous and took the time at the end to show what was replaced and how to operate it. From start of the booking process at 7:30 am to the completion of the job at 3:00 pm the same day, JR Gas kept me informed of the progress of the job and the whole booking system was quick and easy. Thank you for allowing us to have hot showers tonight. I found the Gold Service to be better value than other competing Hot Water replacement services without the extras like new pipes and slab.

Installation Insights for the Vulcan 4 Star 135L

The process of installing a hot water system can seem daunting, but with the Vulcan 4 Star 135L, it doesn’t have to be. This system comes with clear installation instructions, and Vulcan’s service team is always ready to provide additional guidance.

We’ll guide you through the process to install and provide post-installation advice.

Preparing for Installation

Good preparation is the first step to a successful installation. Before installing the Vulcan 4 Star 135L, you should ensure there is sufficient space for the system, taking into account its size and access requirements. Evaluating the current pipework and connections for compatibility with the system is also a vital step.

Having standard plumbing tools on hand, including pipe wrenches, screwdrivers, and pipe cutters, will facilitate an easier installation. And of course, thoroughly reading the instructional manual that comes with the system is a must for understanding the installation steps and requirements.

Step-by-Step Installation Guide

While the installation process of the Vulcan 4 Star 135L is straightforward, it’s recommended to hire a qualified professional to ensure the unit operates safely and at peak efficiency. The chosen site should have a non-combustible and level surface, adequate clearance from combustible materials, and proper ventilation. If the water supply pressure exceeds the system’s recommendations, a pressure limiting valve should be installed.

An approved tempering valve should also be in place to regulate water temperature and prevent scalding. After the system is installed and connected to water and gas lines, a thorough check for leaks and operation is necessary. Any additional operations or settings adjustments can be referred to in the detailed manual provided.

After-Installation Tips

Once the Vulcan 4 Star 135L is installed, the job isn’t over just yet. To ensure your system continues to operate at peak efficiency and maintain its longevity, regular maintenance such as keeping the unit clear of obstructions and conducting periodic system flushes is crucial. Knowing the location of the gas shut-off valve and how to use it in an emergency is another important tip.

For complex issues like gas leaks, temperature fluctuations, and low hot water pressure, professional assistance is recommended. Early detection of issues, such as unusual noises, leaks, or temperature fluctuations, can also help prevent more serious problems down the line.
