The installation of a heater is a simple HVAC task that can be done by most homeowners. Installing a heater requires running a dedicated circuit to the heater. This usually happens to a junction box in the wall.
Switch off the power supply to the circuit you're working on via the panel for breakers. Be sure you are licensed and have appropriate tools for this job.
Installation
Heating installation is a plumbing project that requires permits (if necessary in your location). Certain installations could require a direct vent or a powered direct vent. It is much more difficult to install and should be done by a professional. Install a pressure and temperature relief valve as well as drain pipes. Follow the installation instructions for your heater and the local codes.
The installation of a heater to the wall requires the addition of the locking bar that comes with the mounting kit. The locking screw on the outside is put into the hole that is that is located on the left hand side of the vent pipe at the top. 5). Do not screw the screw into too tightly as this can block the left mounting clip, which will cause that the heater not to sit well in its bracket.
The heater can then be mounted to the wall by using screws included at the top two anchor position. Be sure to align these clips with arrows pointing upward as shown in the Fig. 3 illustration.
Wire
A certified electrician is required to conduct the wiring work for an electric heater. Only an electrician with a license can perform this electrical job, as it requires handling of live wires which can cause shocks or fires. Furthermore, it is essential to adhere to laws and regulations for local and national electrical work. You should also request permits and have the work examined.
When you are in this procedure initially, you must do is shut off electrical power supply to the unit that was previously in use. Then, empty the tank by using a bucket and cut the electrical wires off by unscrewing the screws that connect the terminals. It is the responsibility of the manufacturer to tell you how to wire your heater. If the wires from the previous heater are way too far away from the new heater, put an electrical box made of metal to the ceiling or wall in front of the heater. Run the electric wires through the new heater. The installation of a switch to turn off the heating is recommended.
Most residential heaters use 240 volt lines. It is necessary to have a separate circuit comprising three wires (two each 240 volt and one ground) to be installed on the panel for service. Check the manual for installation of the heater to find the appropriate power, amp, and specifications for voltage.
Nichrome is an all-purpose alloy which is utilized in the manufacture of heating wires. It is composed of the majority of nickel, and 20% percent chrome. The Nichrome alloy is extremely resistant, a high melting point and it is also resistant to corrosion. It is important to note that nichrome has neither the negative and positive poles It's just an electrical circuit that is resistive.
Once the breaker has been correctly sized, connect two 240-volt lines to the heater. The ground wire should be connected. Ground wires are mandatory by law and should always be connected to a grounded metal pipeline or conduit.
It is very important to be aware that the breaker and heater wires need to be connected to the correct earth or grounding system. Carbon monoxide could be fatal if you are not able to connect the breaker and heater wires. To ensure that carbon monoxide poisoning is not averted it is recommended that the breaker and heater wires must be linked to an earthing rod or strap. It's also a great suggestion to have a certified electrician look over the grounding system before turning the heater on.
Connectivity
After you've removed the old heater, and then installed the new one. The final stage is to connect the two. Shut off the water and gas supply valves prior the start of your work. This can prevent loss or damage. If you've got a service disconnect close to your heater or a circuit breakers in your home, it is best to shut off the electricity. If you own a 240-volt test light, it's a good suggestion to put it on before touching any bare wires because it could result in serious injury or death.
You might have thermoplastic copper, or sweat-soldered pipe in the form you use in your home. No matter what material you use, you should install a cold water gate valve near the place where it joins with the heater so sediment does not enter the line of water. Install an union fitting or flare on the gas line that connects the heater if there is a liquid with flammability.
The next electrical connection is in the block that houses the terminals of the control. The grounding wire (green) will go into the terminal "G". The L and T wires go into terminals marked as L1 as well as T2, T3 and T3. The T1 as well as the T3 are connected together in the case of a heater with a one phase. Make sure that the terminals have been tightly pressed.
The protection of the overtemp heater is the most important connection. The wire connects directly to the terminal block which is then connected using the cage clamp. The connection needs the same preparation as the others. So, refer to your labelling or photographs of your original wire connections.
Thermostat
The thermostat is able to read the ambient temperature and determining whether or not the heater is required to be on in order to reach your desired indoor temperature. There are a variety of thermostats and each is operated in a different manner.
There are two main types of thermostats, mechanical and digital. Mechanical thermostats use a strip of metal that heating installations contracts and expands when heated or cools to switch an electrical circuit to the heating system shutting off and turning it on. Digital thermostats, however, contain sensors built into them that monitor the temperature in the vicinity and adjust the flow of current based on this information without having to physically move any metal strip.
The non-programmable thermostats (nondigital) have a dial that allows you to set your desired temperature and adjust it. These thermostats are cheaper and easier to use over digital thermostats, especially when the climate is fairly constant.
It is possible to program (digital thermostats) to turn on or off the heater at specific times during the day or on specific days. They're great for people working from home often, who run late to appointments, or have children at home that require warmth when they arrive.
Data logging thermostats tend to be a little more advanced than others and are able to help solve problems by keeping track of temperature measurements from several sensors around your home. They can also give you a complete analysis of your heating cooling systems consumption.
Check the freshness of your batteries first if there are issues in connection with a thermostat that is smart or digital one. Check that your circuit breaker or fuse box isn't tripped. Finally, if everything is working but the thermostat is still not responding, contact your electrician to have it examined. Perhaps it's time for a reset. If the device is still not functioning even after the reset, you're likely to find that there's an issue with the sensor and you will be required to speak with an electrician for help in fixing it.
