I would call the gas utility and tell them you have a smell. Tell them its coming from the heater and you don't know if its gas or not. They will respond promptly.

You don't want CO.

At this point I think you need legal advice not mechanical.

You need to have the boiler checked by a technician that knows electrical and knows how to troubleshoot. The boiler should not be reaching the high limit temperature

hate to say this but with your symptoms I would strongly say do not run this unit.

I don't know if this is propane or Natural gas but call the gas supplier or the fire dept and have it checked. Landloard is an idiot.

I would not take any chances with this.

The hole is there to allow a tiny amount of flow and thereby prevent freezing. It’s typically not enough to actually heat the radiator up.

I would chalk that up to meter or operator error.. If this is a closed system the water cannot separate and evaporate out?

The numbers for glycols are

Freeze point, ice crystals form, fluid still flows

Slush point, fluid turns to a slushee, cannot be pumped

Burst point, fluid freezes solid and can break pipes and tubes, even Pex.

It depends on the brand of glycol, generally 30-35% mix is adequate for burst protection.

The higher percentage is harder to pump and transfer heat from. No need to overdo the glycol mix.
