HEAT MAKER II Heating Problem

I have a Heat Maker II heating system that cuts off and on. It never gets past 66 degrees. I bypassed the control thermostat by connecting the two wires together and I still had the same problem.
The motor comes on then the heat comes on 1 minute later. Then it cuts off again, and back on again.

I did not notice the valve flame and the ignition on at all.

The purge light blinks while the heat goes off and comes back on solid when the heater fires on.

Th PSI gauge reads about 25. The top red gauge goes from 70 - 130. The lower red gauge goes from 6 - 80.

System uses a Honeywell S9301A Integrated Boiler Control.

What is the FULL model number of your boiler?
