    I believe Lynn Products makes a kit for the 62 series. What burner is on that boiler?

    I took it down to steel. Used high temp refractory cement for target wall and floor. Question 1: Should I use fire bricks for the sides or leave it open to heat quicker.


    Question 2: Should I paint the steel?

    The burner is a Becket - 51771J

    You need to keep to the dimensions of the original firebox. The firebrick creates the proper environment for the flame. If you skimp on it, you will probably not get a clean, soot-free flame.

    What part did you want to paint?

    What's the condition of the refractory on the front plate and the rope gasket?

    Like @Steamhead said, Lynn might, might offer a chamber kit for the 62 but maybe not. The 66/68 series yes. The 62 is going back in time. At least it's not the "pancake model".

    You could have just gotten a "wet pack" target wall and a kaowool blanket.

    The block is cast iron, not steel.
    Paint the combustion chamber?
    No, dont paint it.

    It's the Lynn #1001 "Quickie".

    HVACNUT: No rain cap, so I was considering painting the block with 1200F stove paint to slow the rusting, but might just flake?
    The Refractory on the door had damage and the "rope" looked like flattened epoxy.

    STEAMHEAD: The free advice from the plumber started me down the fire brick road. :) As I stand now would you cement the firebrick to the block to create a solid mass? Or spot cement the brick and leave air space behind for heat.


    The 1st image above shows what looks like an air gap around the chamber. Mine was is such disarray I don't know how it was setup 50 years ago.



    Thanks for all your help, as you can tell I am new to this, but want to get one more season before a new boiler.

    IIRC the original fireboxes in those 62s were held together with metal bands, not cemented to the cast-iron.
