Safety Information
Prioritize safety! The Ideal Logic Heat H15 manual details critical carbon monoxide warnings and emergency shut-off procedures for safe operation.
Carbon Monoxide Warnings
Crucially, carbon monoxide (CO) is a colorless, odorless, and potentially fatal gas produced by incomplete combustion. Your Ideal Logic Heat H15, if not properly maintained or ventilated, can produce CO. Always ensure adequate ventilation in the room where the boiler is located.
Install a certified carbon monoxide detector, following the manufacturer’s instructions, in a central location near sleeping areas. Regularly test the detector’s functionality. Be aware of the symptoms of CO poisoning: headache, dizziness, nausea, breathlessness, and confusion.
If the CO detector alarms, immediately shut off the boiler, evacuate the premises, and call emergency services. Never ignore a CO alarm. Refer to the full manual for detailed safety guidance and professional servicing recommendations.
Emergency Shut-Off Procedures
In an emergency, knowing how to quickly shut off your Ideal Logic Heat H15 is vital. Locate the gas supply valve – typically near the boiler – and turn it to the ‘off’ position. This isolates the gas supply, halting operation.
Additionally, the boiler itself has a power switch, usually located on the front panel. Switch this to the ‘off’ position to disconnect the electrical supply. Familiarize yourself with these locations before an emergency arises.
If you suspect a gas leak, do not operate any electrical switches. Evacuate immediately and contact your gas supplier or emergency services. Consult the full manual for detailed diagrams and specific instructions related to your installation.
