Gas Heaters

[fmpayne64]

We just moved into a new house that has radiators for heating. When we checked the gas heater I noticed there are 2 pressure readings on the front of the heater. The one goes from 0 to 60 and the other starts at 100 and goes to 360. What should the maximum pressure be for these readings? Is there danger level because right now the first one is reading 20 and the latter is on 160?
