Cleaning of the heat exchanger. MCZ Powerbox Compact-Link

INSTALLATION AND USE MANUAL

5.2.3. Cleaning of the heat exchanger

Halfway through the winter, but especially in the spring, you will need to clean the air spaces where discharge smoke passes.

This cleaning must be done in order to remove all combustion residues before time and humidity let them harden and make them difficult to remove.

When the unit is cool, open the fire door and extract the ash drawer and grate. Then loosen the three screws located just above the fire mouth to remove the bracket that holds the internal Alutec refractory parts. Gently remove the sides and then the back.

When removing the refractory parts, be careful not to let them hit each other as they may chip or break. Put them in a safe place until it is time to re-install them.

As soon as the refractory material back is removed, you will notice that the steel back has openings where smoke normally passes. Insert a bottle brush (preferable iron) in all of the openings and scrape the walls of the fire box so that the ashes fall into the part below where the inspection panels are located.

Loosen the bolts and open the inspection panels located under the ash drawer. With a vacuum cleaner attachment, remove all the ash and soot from the heat exchanger, again using a brush and the attachment.

Put everything back in place by performing the above steps in reverse order.

5.2.4. Cleaning of smoke duct and connection

When the unit is extracted, on the left it is possible to work on the smoke intake volute (1) for cleaning and maintenance. To perform this maintenance, you will need to remove the smoke intake fan.

On the outlet of the volute there is a gasket (3) that seals the connection with the smoke connection (2). Always check the condition of this gasket and replace it as needed. The gasket can also be adjusted using a screw. You can turn the screw to increase or decrease the pressure on the connection.

Cleaning and inspection panels

At the rear of the unit, at the volute outlet, there is the smoke connection with its ash collection compartment (4). Also clean this compartment with a vacuum cleaner, inserting the attachment in the insertion hole of the volute.

2 Clean the smoke discharge system, especially in the area of the connectors, curves and any horizontal stretches of pipe. For information on cleaning the flue pipe, contact a professional chimney sweep.

WARNING:

The frequency with which the smoke discharge system is cleaned should be determined based on the type of use that is made of the product and the type of installation.
