## Summary description

Wired gas detector BLOW model 50-622# (TG20) operates on 230V and is designed to detect gas leaks in residential and commercial spaces. The unit houses a gas sensing element that triggers an alert when gas concentration rises, enabling timely response to natural gas or other combustible gas leaks. Suitable for continuous monitoring near boilers, stoves, and gas installations.

## Long description

The BLOW 50-622# TG20 wired gas detector is a mains-powered 230V device designed for continuous monitoring of combustible gas concentrations in homes and commercial premises. It incorporates a gas sensing element that responds to rising levels of natural gas and other flammable gases, providing an early alert to help occupants or staff take appropriate safety measures. The compact wall-mounted unit is intended for installation near boilers, stoves, gas meters or other gas installations where prompt detection is required.
Advantages
The detector offers constant, hardwired power from a 230V supply to ensure uninterrupted operation without reliance on batteries. Its gas sensing element is calibrated for sensitivity to combustible gases and designed for reliable triggering at elevated concentrations. The device is compact and suitable for fixed installation, reducing the need for frequent handling. Because it is intended for indoor use near gas appliances, it supports continuous monitoring of areas with potential leak sources.
Suitable for
Domestic kitchens and boiler rooms
Small commercial premises with gas appliances
Apartment buildings and rental properties requiring fixed detectors
Service rooms and maintenance areas with gas-fired equipment
Key specifications
Power supply: 230 V AC mains
Sensor type: combustible gas sensing element (for natural gas and similar gases)
Mounting: wall-mounted, fixed installation
Application: continuous indoor monitoring near gas appliances
How to use
Install the BLOW TG20 detector on a wall close to the potential leak source, such as above or near a gas boiler, stove, or meter, following local electrical and safety regulations. Connect the unit to a 230V AC supply using appropriate wiring and protective devices; installation should be performed by a qualified electrician. After power is applied, the detector continuously monitors ambient air for combustible gas and will activate its alert output when concentrations rise above its trigger threshold. Regularly test the device according to the manufacturer’s test procedure and local safety guidelines to confirm proper operation.
Usage recommendations
Place the detector at breathing height or as recommended for the specific gas type, keep it clear of obstructions and direct heat sources, and avoid mounting in areas with excessive dust, steam, or corrosive vapors. Do not use the detector outdoors or in locations exposed to weather. Schedule periodic functional checks and professional maintenance to ensure reliable long-term performance.
