since furnaces burn fuel in order to produce heat, they can develop some serious safety issues if they begin to malfunction.
A heat detector should also be located directly on the ceiling; however if this is not possible, the unit can be installed up to 125mm below it. Sloped Ceiling With a sloped ceiling the position of a smoke or heat detector needs to be measured vertically from the peak.
High Efficiency 90+ Condensing Gas Furnace Manufactured By A Lennox International Company 421 Monroe Street Bellevue, OH 44811 The installation of the furnace, wiring, warm air ducts, venting, etc. must conform to the requirements of the National Fire Protection Association; the National Fuel Gas Code, ANSI /NFPA No. 54 (latest edition) and the National Electrical Code, ANSI/NFPA ...
Detector location Fire detection. Various rules of thumb are used to determine the location and coverage of the different types of fire detector. Point heat detectors in open, naturally ventilated areas are sited at approximately a density of 1 per 25m2 and at spacing of 7m with a maximum distance from bulkheads of In enclosed mechanically ventilated modules, they are sited at ...
· This is why there are very strict fire protection laws and regulations when it comes to fire protection. ... Sensors may be sensitive to smoke, heat, gaseous combustion products or radiation. Normally the control and indicating equipment operates a fire alarm system and it may perform other signalling or control functions as well. Automatic sprinkler systems can also be used to operate a fire ...
Inside the burner compartment, the flame sensor will be located in front of one of the inshot burners. Be careful not to mistake the igniter for the flame sensor. There are different types of ignition systems in an electronic ignition gas furnace. If you have a hot surface ignition system, the hot surface ignitor can be fragile and easily break.
· The flame sensor is one among the many safety features inside of a gas furnace. There are some being checked right before the gas is allowed to burn and some right after the gas is burning. Those that are checked right after the gas is burning are available to safeguard you and your home from dangerous conditions while your gas is burning. The flame sensor is …
FIRE PROTECTION SYSTEMS to close and send an alarm. If the expanding air can leak out of a vent hole, the resulting pressure will be reduced. However, if the air expands at a rate faster than the vent hole can compensate for, the contacts will close and an alarm will be sent. Combination heat detectors can combine the two operating principles of

The manual reset rollout switch located above the burner may be tripped. Check for excessive manifold pressure. Check for blocked flue or heat exchanger. 4 Blink Pressure Switch is closed. The switch contacts remain closed during the off cycle. The points may have welded together or have become stuck. The furnace will not go into the ignition sequence if the pressure switch …
Utility and Furnace Rooms. The low volume steam and gases produced by mechanical equipment will not activate the CFH10. The recommended Fixed Temperature Setting is 135°F (57°C). Recommended Locations for Your Heat Sensor. 6 Bedrooms. Smoke Sensors are required protection in all sleeping rooms. A bedroom is NOT a good location for a stand …
· Fire sprinklers are activated by convective heat transfer. In Operation of Fire Protection Systems, the authors sum up the process as follows: Within a room, a plume of hot gases will rise until it hits the ceiling and then splits, forming a ceiling gas jet that pushes out to both sides of a room. The thickness of this jet flow is roughly ...
Observe heat detector location guidelines. Ambient temperature operating range is 32° F to 100° F (0° C to 38° C). Temperature fluctuations should be below 6° F/min (° C/min). Detector locations should be determined only after careful consideration of the physical layout and contents of the area to be protected. Refer to NFPA 72, the National Fire Alarm Code. On smooth …
