Gas conversion burner replacement help

Bruce Ambuter

I am seeking information on my steam boiler system, which works very well as well as operating when AC lost. I would like to either purchase a new gas conversion burner or get parts for the old one. Replacing the heating system is too much $$$ considering the cost of the internal asbestos removal and other assoicated costs. The pipes are fiberglass insulated.

Currently I run a pellet stove for main heat,
Gas bill for year is about $1000

Can I legally replace the the present gas conversion burner with a new one that uses a thermocouple ignition?
If not can I simply purchase spare parts in the event of failure?
Is the trend toward States not allowing mortgages to be written for houses that have asbestos lined ( although
intact) heating systems. In which case, I should replace the heating system as soon as possible.

American Radiator company (coal converted to oil to gas )
Ideal Arco
Number 223 Series 3

Gas conversion burner
HeatBath by Mardan, Inc Model 27Pr Serial # 1255
Max 270000 BTU's min 70000 BTU's
Uses Honeywell PowerPile Gas Valve VS8187A1369
WOuld you happen to be able to help determine the Honeywell part number
for the assoicated pilot generator valve?

Thanks for any information you can provide me.

I really enjoyed the "The Lost Art of Steam Heating".
