AMULET INSTALLATION INSTRUCTIONS
(Required on some models)
The amulets provided have been selected by Riello to protect the combustion tube from hot exhaust gases and
flame. This protection may be needed in applications where the combustion tube opening in the combustion
chamber refractory is larger than the tube outside diameter.
The amulet has been sized to fit Riello Model 40 sizes F3 and F5 plus the Riello Model R35.
When installing this amulet, handle it carefully. Do not exert undue pressure when pushing the amulet over the
combustion tube. Excessive force can result in a broken amulet!
If the amulet will not fit easily onto the tube, remove a small amount of the inner diameter with a sharp knife to
provide the necessary clearance.
The diagram below shows the proper position of the amulet after installation.
