Burnham Cast Iron Baseboard Installation
You need to know how to install Burnham cast iron baseboards. Let’s see the process.
Prepare the wall
To prevent heat loss, insulate the stud space behind the assembly with 4” mineral wool batts up to 12” in height. This step is essential if the heater is recessed.
Recess the assembly:
- Nail a ½” plaster ground to the studding.
- Keep the bottom of the plaster ground 10” above the floor.
- Now, line the back of the recess with aluminum foil by stapling the foil with a staple gun.
Assemble the baseboard:
- The shipping length can be up to 6″ cast iron baseboard.
- For longer baseboards, there need to be a few subassemblies.
- To assemble the subassemblies, line them up faced down on the floor and near the wall where they are to be installed.
- Clean the nipple ports and nipples with kerosene or gasoline and wipe them off with a cloth.
- Apply some lubricant on the nipples and insert them into the nipple ports.
- Tighten them as much as possible.
- Cut two pieces of 1 ¼” steel pipe 15” long and then place them on the two clamp handles for necessary leverage.
- Make sure the clamp nose is resting on the bottom of the recess. This is very important.
- Now simultaneously press the two clamp handles down so that the castings are drawn together.
- Make sure the clamp is not tilted because that can break the casting.
- Use a woodblock hammer to ensure that the nipples are drawn evenly.
- Do not use metal hammers on the baseboard.
Install the baseboard:
- In the end, install all the fittings in the sections while all the parts are still on the floor.
- Before raising assemblies to an upright position, install bottom center support. For this, refer to the table of supports provided by the manufacturer.
- Now install the spring clip bottom center support.
- Insert the ¼” cap screw into the clip until the head is more or less ¾” from the clip.
- Place the assemblies in position and fasten them to the wall using top center support. Use the numbers in the table provided by the manufacturer.
- Now insert the top center support into the air outlet opening using a wood screw.
- Adjust the bottom center supports by turning the cap screws until they reach the floor.
- Now connect the assemblies to the piping, fill them with water, and check for any leakage.
- Do not exceed the 30 psi pressure mark and do not test pressure with air.
Install the valve enclosures:
- To access the valve enclosure, remove the knockout at the end of it.
- Bend the tab so that the hole is on the inside facing the wall.
- Fasten the valve enclosure to the baseboard with a ¼” thumb screw.
- Use screws to fasten the valve enclosures to the wall.
Install the corner plates:
- Place the corner plates where the baseboard assemblies overlap.
- Secure them with wood screws.
- To install on tile, drill ½” holes aligned with the holes in corner plates and secure the corner plates with screws.
- To install on masonry, drill the same size holes 1” deep and use slightly oversized wood plugs. Finally, secure the corner plates with screws.
Install the baseboard extensions:
- Install hangers by screwing them to studs so that there is a hanger present at the extreme ends of the baseboard extension.
- Now install end caps on the extension using the hangers.
- Install splice plates by attaching hooks to them and then snapping them into position behind the extensions.
Complete the installation:
- To prevent air leakage, install an air seal. Use 1” tape for this purpose with a thermal setting adhesive, which you can collect from Burnham at a low cost.
- Now install ¾” quarter round or other wood moldings on the top of the baseboard, even on top of the air seal. Nail the wood molding in place.
- It’s time to paint the baseboard. The baseboard comes with latex paint, which must be used with a high-grade oil. This paint prevents the baseboard from rusting. Do not use wall paint on the baseboard.

I am in desperate need of two 2-foot sections exactly like the first picture in this post. I have an 18’ section consisting of nine 2-ft sections and unfortunately there was corrosion in one joint which caused leaking and now I have to replace the two 2-ft sections. Do you have a source for these? Most I am seeing are 10” tall and mine look exactly like those in your photo. Any help is greatly appreciated.
