The installation of a heater is an easy HVAC project that can be done by most homeowners. Installation of a heater will require an electrical circuit that is dedicated to the heater. It is typically connected by a junction board in the wall.
You must shut off the power source to the circuit you are doing work on by using the panel for breakers. Also, ensure you have the right tools and a valid permit to perform this work.
Installation
The setting up of a heating system is considered a plumbing job and will require a permit to be granted by your location. Certain installations could require a direct vent or a powered direct vent. It is more difficult and should be left to a professional. Install a pressure and temperature relief valve as well as a drain pipe. Install the correct instructions for your heater and any local code.
In order to install a heater onto the wall requires the addition of the locking bar included in the mount kit. The process involves installing the locking screw from the outside into the hole located at the base of the vent pipe on the left hand side (see Fig. 5). Be careful not to screw gas heat installation the screw to far, as this will obstruct the left hand mounting clip and cause that the heater not to sit well in its bracket.
The heater may then be connected to the wall with the screws provided on the two highest anchoring places. In Fig.3 make sure the clips are placed to ensure that the arrows point towards the upward direction. 3 illustration.
Wiring
A certified electrician is required to complete the wiring for an electric heater. Only a licensed electrician should perform this electrical job, since it requires the handling of live wires, which could cause shocks or fires. Additionally, it's important to follow laws and regulations for local and national electrical work. Additionally, you must seek permits, and get your work inspected.
First, turn off power to the unit that is older. In the next step, empty the tank by using an empty bucket. Finally, disconnect the electrical wires by unscrewing the screws that connect the terminals. Wire the new heater according to the manufacturer's guidelines. If the wiring from the old heater is insufficient to connect the heater you want to install, place an electrical device made of steel at the top of the ceiling or wall close to the heater, and connect the electric wires through it. It is a good idea to set up a shutoff valve in the vicinity of the heater.
Most residential heaters use 240 volt lines. This requires a dedicated circuit consisting of three wires (two 240 volt and one ground) to be installed on the service panel. Make sure the circuit you are installing is properly sized by consulting the heater installation manual for specific wattage and amperage requirements.
Nichrome is a popular alloy used to make heating wires. It contains 80 percent nickel and 20 percent chromium. Nichrome is corrosion-resistant, has an extremely high melting temperature as well as a lower resistance. It's important to remember that nichrome has neither an alternating pole for positive or negative as it's the result of a resistive circuit.
Once the breaker has been adequately sized, connect two 240 volt lines together to the heater. Attach the ground wire. The ground wire is required by code and should always be attached to a grounded metal pipe, or conduit.
Remember that both the wiring for the breaker and heater needs to be grounded or linked to an earthing system. Failure to do so can lead to dangerous carbon monoxide poisoning. To stop carbon monoxide poisoning, the breaker and heater wires must be connected to an earthing rod or strap. It is also a good idea to have a qualified electrician examine the grounding mechanism prior to turning the heater on.
Connections
The final step after you've removed the old heater to join it up with the new heater. Close the gas and water supply valves prior to starting your work. This will prevent any damages or leaks. Also, you may want to switch off electricity employing a disconnect switch in sight of the heater or a circuit breaker. Use a 240-volt tester before you touch any exposed wires. They could be fatal or cause severe injury.
There are thermoplastic, copper, or sweat-soldered pipe depending on what type that you are using in your residence. Install a gate valve for cold water that connects the pipe to the heater, regardless of the type of material. This prevents debris from entering the water system. Install an union fitting or flare on the gas pipe that joins the heater in case there is a liquid that is flammable.
After that, connect the wires that are electrical to the terminal block located on the control. Green ground wire is connected to the terminal marked "G." The other wires (L and T) connect to terminals marked L1, T2 and T3. If you are using a single-phase heater, make sure the T1 and T3 connections will be connected. Be sure that the connections are firmly secured.
Overtemp protection for the heater is the connection that makes it final. It connects through the terminal block, which is then connected using an enclosure clamp. The process of preparing this connector is identical to preceding ones. Make sure you follow your label tags or a image of the wire connections to complete the process.
Thermostat
The thermostat functions by analyzing the temperature of the surrounding area and then deciding the temperature at which your heater is required to be on to attain your preferred indoor temperature. It's an easy concept but there's an array of thermostats that work in different ways.
The thermostats that are digital and mechanical are two of the most popular kinds. Mechanical thermostats depend on an iron strip that expands and expands when heated cools to switch an electrical circuit that connects to the heating system shutting off and turning it off and. Digital thermostats are equipped with sensors inside that detect the surrounding temperature and manage current flow according to that information, without the need to physically move any metal strip.
The non-programmable thermostats (nondigital) feature the dial, which lets you to set the desired temperature and adjust it. They tend to be less expensive than programmable thermostats, and might be more convenient in places where weather conditions don't fluctuate drastically from one year to the following.
The programmable (digital) thermostats let you design a program for your heater to turn on or off at specific times of day and during certain days during the week. They're ideal for people who work from home frequently, or who are late for appointments, or have kids at home who require warmth when they arrive.
The thermostats that log data are higher-end version than others. They can assist you to detect issues through the tracking of temperature readings from multiple sensors in your home. The thermostats will provide you with a detailed account of the heating and cooling system use.
Examine the health of your batteries first, if you're having issues with a smart thermostat or digital one. Also, make sure that the fuse box or circuit breakers aren't broken. If the thermostat still does not react after all of the settings have been switched on, you need to call an electrician. You may require a reset. If the device is still not functioning even after the reset, you're likely to find that there's a problem with the sensor and you will require an electrician to fix it.
