The document describes the Potterton Netaheat Profile boiler, a fully automatic heating appliance designed for use with natural gas. This user's guide provides essential information for operating and maintaining the boiler, emphasizing safety, efficiency, and longevity.

Function Description:

The Potterton Netaheat Profile boiler serves as a central heating and domestic hot water provider. It operates automatically, requiring minimal user intervention beyond setting the thermostat and other controls. The boiler heats water that circulates through a central heating system and/or is stored in a domestic hot water cylinder. Its operation is contingent on the availability of both gas and electricity supplies. The boiler is equipped with a safety thermostat to prevent overheating, which will shut down the appliance if water temperatures become too high.

Important Technical Specifications:

Model Numbers: The guide covers models 30e, 40e, 50e, 60e, and 80e. Notably, the 50e model is specifically mentioned as being found in two-bed flats, suggesting varying capacities or design considerations for different dwelling sizes.
Fuel Type: This appliance is designed exclusively for use with natural gas.
Electrical Supply: It requires a 240V~50 Hz electricity supply.
Earthing: The appliance must be earthed.
Fusing: If a 13 amp (BS 1363) plug is used, the appliance must be protected by a 3 amp fuse. If any other type of plug is used, a 5 amp fuse in the circuit is required.
Boiler Thermostat Range: The boiler thermostat knob can be set from 'O' (OFF) to 'Max', with graduations 1 to Max corresponding to an approximate temperature range of 55°C to 82°C (130°F - 180°F).
Safety Features: Includes an overheat limit thermostat to protect against excessive water temperatures. A reset button is provided for this thermostat.

Usage Features:

Automatic Operation: The boiler is fully automatic, simplifying its use for homeowners.
Boiler Thermostat Control: Users can adjust the water temperature leaving the boiler using the thermostat knob. Lower settings (1 or 2) are suggested for summer months when only domestic hot water is needed for bathing or washing up, while higher settings are recommended for central heating during winter. A warning is given about potential scalding temperatures (around 82°C/180°F) if domestic hot water is not independently controlled at higher boiler thermostat settings.
Lighting Procedure:
1. Ensure the boiler thermostat knob is at '0' (fully anti-clockwise).
2. Switch 'ON' the main electricity supply.
3. Ensure any electronic programmer or time control is in an 'ON' period.
4. Ensure any room and/or cylinder thermostats are set to a high temperature.
5. Turn the boiler thermostat to the desired setting; the main burner should light after a short period, visible through the sight glass on the front.
Shut-Off Procedure: To turn off the boiler, simply turn the boiler thermostat knob to '0' or switch the external programmer to the 'OFF' position.
Longer Shut Down Periods: For extended periods of non-use, the boiler thermostat should be set to '0', and the electrical supply isolated (either at the isolating switch or by unplugging).
Troubleshooting (User Checks): Before calling a service engineer, users are advised to check:
1. Gas, electricity, and water supplies are turned on.
2. Time control (if fitted) is in an 'ON' period.
3. All thermostats are not on low settings.
4. The overheat limit thermostat has not tripped (requires pressing the reset button, accessible through a hole on the underside of the controls cover).
Compartment Installation: If installed in a compartment, it should not be used for storage, and all ventilation openings must remain unobstructed.
Gas Leak/Fault: In case of a suspected gas leak or fault, users must turn off the appliance and consult their local Gas Region or Service Engineer immediately.

Maintenance Features:

Professional Installation: The appliance must be installed by a competent person, adhering to the Gas Safety (Installation and Use) Regulations 1984.
Casing Integrity: The boiler casing should not be removed by anyone other than a qualified service engineer. The appliance must not be operated without the casing correctly fitted and forming an adequate seal.
Regular Servicing: Regular skilled servicing is crucial for maintaining safe and efficient operation throughout the boiler's lifespan. An annual service contract is recommended, and users are encouraged to contact their local Potterton regional service office or return a provided postcard for more information.
System Checks: It is advisable to have the entire heating system checked annually to prevent excessive costs from misadjusted thermostats or radiator valves.
Cleaning: The outside of the boiler casing can be wiped with a damp cloth to remove finger marks. Abrasive materials should not be used.
Frost Precautions: To prevent freezing during cold weather when the boiler is shut down, several methods are suggested:
1. Insulation of the boiler and pipework, ensuring ventilation is not impeded.
2. Completely draining the water system for long periods (on sealed systems, this must be done by a competent person, e.g., a Service Engineer, as it involves removing a drain cap within the boiler case).
3. Having a low limit thermostat fitted (note: this will not work if the boiler is completely shut down and electricity is off).
4. Running the boiler at low thermostat settings when it would normally be shut off if no other frost protection is available.

The document emphasizes that the information provided is intended to help users maximize comfort and minimize trouble and cost, while highlighting the importance of professional installation and maintenance for safety and efficiency.
