Assembly Guide

Real cast iron radiators are a thing of beauty. But another thing they are is heavy! 

If your cast iron radiator weighs over 100kg, you will need an additional piece of kit called a joining tool to connect each section of your radiator together. 

Depending on the width of your cast iron order, the radiator may be split into 2 or more sections to ensure that it arrives safely.

This guide will show you step by step how to use the joining tool to assemble your new cast iron ready for installation. 

But first, let’s answer a couple of your FAQs.

How To Assemble Your Milano Cast Iron Radiator

Step 1 – Prepare The Sections


Please Note: Your order will be shipped on two or more pallets. We recommend moving your radiator using the carry straps onto a single pallet for installation.

Using the shipping pallet as a secure base to work on, prepare the two radiator sections for joining.

Section A connects to Section B (and if your radiator is long enough to split into further sections, then B connects to C, C to D and so on).

If you have multiple split radiators this will be indicated with a number (e.g. A1 connects to B1, A2 connects to B2 etc).

Step 2 – Screw In The Joining Nipples & Gaskets


Being sure to use the correct opposing threads, carefully screw in the joining nipples provided and put in place the graphite gaskets for the middle section connection.

Step 3 – Join The Radiator


Slowly push the two sections of radiator together, being sure that the joining nipples sit neatly in the thread ready to be joined.

Step 4 – Turn The Joining Key


Take the radiator joining key and insert it into the radiator from one end.

Slowly make one full turn of the joining key until the center of the radiator is brought together.

Repeat this for both the top and the bottom connections, being sure to make firm and even connections.

Step 5 – Tighten The Sections


Using a bar or a spanner begin to tighten the top & bottom sections of the radiator.

Then, using a torque wrench, tighten each section to the recommended torque setting of 250 Nm (Newton metres) or 185 lb/ft² – being careful not to overtighten.

Step 6 – Add The Gasket & End Bush


To finish the assembly of your radiator, place the brown gambit gasket around the inlet of the end section.

Replace the end bush and tighten using a spanner and finish by tightening with a torque wrench to 250 Nm (Newton metres) or 185 lb/ft² .
