High-Efficiency Gas Furnace And Forced Air Zone Controls

By Michelle McDonald


When a new object does not perform to its rated efficiency, customers rarely think it is because it was improperly installed; they blame it on factory faults or damage during delivery. High-efficiency gas furnace installation, if done correctly, reduces home energy consumptions and forced air zone controls save money. The necessary procedures and steps of properly installing a furnace in an existing house are given below.

When one part or few parts of an existing system gets replaced, new parts bought should be able to fit the space of the old ones perfectly and have an improved performance. That is why before the furnace installation can take place, a certified contractor should come and check out the old furnace system. This is one of the 4 important steps to be followed when retrofitting a gas furnace and it is called the pre-Changeout phase. The other remaining steps are; installation, commissioning, and lastly, education and maintenance.

In this stage of the process, the aim is to calculate the new system s required specification. Furnace systems are designed differently to serve a different purpose in terms of the heat they release and their shape, size and their design. So a contractor will go the old system and calculate its heat load and measure the circumference and area of its ductwork. From then on, they will know which furnace system will meet all their requirements and make a purchase.

The second step is called the installation phase. The newly bought parts and furnace are now ready to get installed. The furnace s manufacturer normally gives installation instructions, they are unique to every furnace. The contractor should follow those instructions during the process to avoid making mistakes. The rules in the Health and Safety Regulations Act should also be followed during the process.

When connecting the old ductwork to the new one, aluminium tape must be used to seal them to avoid air leakages where needed. Also, the furnace should be well levelled, otherwise the acid condensate released during the furnace operation may cause corrosion at a later stage. The opportunity of the air to flow at a turbulent from should be prevented during the installation process. That can be done by putting turning vines in the furnace and tapering where needed.

Once the furnace is installed, a certified gas fitter should be called to confirm and/or modify the new system so that it meets the manufacturer and the owner s performance requirements. This is the commissioning phase, the process involves checking individual system components like wiring and filters, checking the air pressure, temperature rise, static pressure and firing rate, and finally recording all these in a checklist before making the necessary modifications.

The homeowner should be given that checklist and if it shows that some modifications are needed, he/she should tell the contractor which installed the furnace. The last step should be taken by the contractor and it involves informing the homeowners about what to do when maintenance is needed, the warranty and how to use the furnace.

High-efficiency gas furnace installation should not be taken as a do-it-yourself project, certified contractors should be hired to complete the task. If they don t follow the above-mentioned steps then you ve chosen wrong contractors.
