Hot water and central heat system

The system operates on city gas. The heater system is electronic and ignition is fully automatic. The main electric switch is on the wall to the left of the stove. The thermostat that governs the radiators is just to the left of the refrigerator.

The hot water boiler is in the corner of the kitchen. On the front panel are three control dials and a pressure meter. We have found that keeping these two dials set at a middle position works well.

Summer use:
1. The control dial on the left should be in the “hot water only” position.
2. The switch on the thermostat (by the refrigerator) should be set to “off”.

Winter use:
1. The control dial on the left should be in the “hot water and radiator” position.
2. The pressure gauge should be between 1 and 2.
3. The thermostat should be set to about 20-22 degrees and the switch can be turned on or off as needed.
4. The radiator in the living room has a blower that forces hot air around the living room. The blower is not connected to a thermostat and must be turned on and off manually. The system is most effective when the fan is kept at a low-medium-low position.

The meter on the right of the heater/boiler indicates the temperature and pressure of the water in the system.. The pressure should be at about 1 ½ - but not below 1 and not over 2. If it goes over 2, water should be released from any radiator valve. If the dial goes below one, water should be added to the circuit by opening the smaller of two black valves directly behind the pressure dial until pressure is restored. The larger valve is easy to find – the smaller is above and in front of the larger one.

If per chance the city turns off the gas for some reason, the system will block automatically and the red light above the control dials will turn on. Pushing the button will reset the system.
