What are some preventive maintenance required for Boilers

Introduction

You can perform the preventive maintenance routines on your residential boiler – In Floor Heat Boiler, when you inspect and analyze the parts regularly. Many of the procedures involve cleaning, minor replacements, and adjustment and alignment of the loose parts. It is better to make a checklist of the parts you have to inspect and the maintenance procedures.

Part diagnosis and Replacement

Diagnosis of the boiler parts from the vent piping, air piping, relief valve, condensing system, water cut off system boiler piping.

Vent Piping

The vent pipe comes in two basic types, namely the C and B. C is primarily used as connector. Its application is to vent the gas. The type B is used in most of the old model boilers. Check the screws and the assembly in the piping. If there are any loose parts and screws, you have to tighten them up using the right tools.

Boiler Valves

The boiler valves are the parts which come under frequent pressure during the operation. They also tend to wear out and loosen faster. So, you have to pay special attention to the screws and the connecting parts in the valves. If screws, washers and the components are worn out, you have to replace them.

Pressure Pumps

The pressure pumps are the key components of the gas boiler calgary system. Check the assembly for any loose screws and tighten them.

Boiler Leak Maintenance

Visually examine the boiler’s external parts for the leaks. Then you have to focus on the boiler’s interiors starting from the condensate trap, through the piping and air openings, to the burner pipes and the fuel pipes. In case of the latest models of the boilers, you can open the front panel completely. Then it allows you the free access to the pipes, valves and the joints.

Use the focus light or the magnifying glass to check the minor cracks on the pipes or damages to the screws and the connecting parts. The procedure may seem to be tedious and time consuming. But it will be worth the effort.

 Filter Cleaning/ Replacement

The calgary boiler filters are made of fiberglass, pleated materials, or an electrostatic material. Check the entire filter parts for damages or cracks. If you find any such signs it is better to replace it. Otherwise you can take the filter out and clean it.

Turn off the burner and shut down the gas supply. Open the top lid on the filter part using the spanner. Then you have to make sure of the parts safety. As you start unscrewing, the pressure from the housing assembly gets released to the external environment.

Then you can open the access panel slot and take it out. Your first task is to vacuum the chamber containing the filter. It removes most of the accumulated dirt and dust. In the next step you have to clean the filter. It is possible to do it by keeping the filter in its potion or by removing it. The best suggested practice is to take it out.

Spray the cleaning liquid all over the surfaces. Let the liquid drench the filter for 10 to 15 minutes. Then you can use a soft bristled brush to rub the filter top surface. It removes all the deposited dirt from the top surface. Check the filter once and vacuum it. But you have to be careful about the volume of pressure applied from the vacuum as it can damage the finer elements in the filter. In the next step you have to clean the filter slots from any of the accumulated dirt. Replace the filter to its original slot and screw the sides. Then close the access panel.

Part Lubrication

The motors on the air fans, water pump, fuel pump, bearing, and the joints on the rotating and moving parts require lubrication. Apart from that you will also need to apply the anti-corrosion liquids on the pipes, joints, and the connecting parts.

Refer to the product manual and find out the exact location of the motors. You have to open the access plates or the covers from the top and expose the parts to be lubricated. Clean the exterior with the help of a soft nylon pad. Use a miniature vacuum to clean the deposits of the dirt and dust from the surfaces and the interior parts.

Fill the OEM recommended lubricant into the sprayer. Then you can spray the lubricant exactly according to the service manual provided by the manufacturer. Avoid using the lubricant to excess level.

Boiler Cleaning

Apart from the filter, you have to clean the valves, vent, burner, exchanger, pipes, and the expansion tank. If the size of the boiler is compact, you may not be able to reach the internal parts. In such cases you have to use the high pressure vacuum for the cleaning.

Burner Cleaning

With some experience, you can clean the burner by taking it out from the assembly. Open the front access panel of the boiler and you can view the burner within the lower part of the boiler (It may vary, depending on the brand and model).

You have to check the type of ignition used in the burner before dismantling it for cleaning. Many of them use the standing pilot type while the others use the intermittent pilot with the electronic ignition.

The first step is to loosen the burner tube. You can see the screws between the tube and the valve which have to be unscrewed. Use the standard spanner provided by the OEM. Or you have to refer to the service manual and get the recommended standard spanner.

Slowly remove the burner from the slot without damaging it. Use a vacuum to remove the accumulated dirt within the burner. Avoid using flammable liquids and use only the OEM recommended liquids. Rub the externally visible parts of the burner with a soft cloth. Reassemble the parts and replace the burner into its original location.

You have to perform the cleaning and lubrication procedures once in a month at least to ensure proper running. The visual inspection, fine tuning and the replacements have to be done as advised by the OEM.

NOTE

 

If you don’t have the expertise or the experience for the maintenance, it is better to call the boiler repair and maintenance professionals.
