We were wondering if the air coming off the heat pumps against the side of the house would cause this. Move some dirt onto the fire site and mix thoroughly to fully smother it. I have a two ton round condensing unit which does not have near the recommended clearance on two sides (house wall on one side and a fence consisting of horizontal 1'' x 6" boards with 1" gaps on the opposite side). (Feb 19, 2015) Chuck said:Are there any clearance requirements for condensing units and entrances? The heat pumps blow air up and we can see that the air hits the windows on that side of the house. Never reach into a campfire to rearrange pieces of wood. Where either these conditions are possible I'd increase the clearance distance to 10 feet or 3 meters. ONE LESS SPARK CAMPAIGN TOOLKIT. Be aware that rocks obtained from the river may explode due to moisture in the rock becoming superheated by the campfire.
The sources for that data do not explicitly specify a clearance from a gas appliance direct vent terminal cap to an A/C compressor/condenser. So obstructing airflow out at the unit top will also reduce air flow across the condensing coils, shortening equipment life and cutting its efficiency. Typically, because of the electrical or water connection, this will help push the fridge out slightly away from the wall, but 1-2 Inches is ideal. But of course the final authority is the equipment manufacturer. One Less Spark–One Less Wildfire Watch the campaign PSA on preventing wildfires caused by people. Or see CLEARANCE DISTANCE, HVAC FAQs - questions & answers posted originally at this page. Side Clearance Requirements Many newer fridges have zero-clearance doors -- doors that open flush with the sides of their cabinets. Details about refrigerant piping diameters, distances, and effects on equipment operation are. In our photo above, from a Minneapolis MN home, these two compressor/condenser units are just about three feet apart - a little close, and that right-most larger compressor/condenser unit is too close to building walls, a clothes dryer vent, and shrubbery. away from the campfire. 1. respect the required working/service clearance distances: Blocking air flow through the outdoor A/C or heat pump compressor/condenser unit is a really bad idea that shortens equipment life (as the equipment runs hotter) and increases system operating costs (for the same reason - hotter operating temperature means lower efficiency during the cooling season). Once the water has been applied, stir the dampened coals and douse it again with water. Legal experts whose opinions we've come across online claim that HVAC equipment will be turned "off" prior to servicing, so the NEC's equipment clearance distances that apply to "energized equipment" would not apply to an air conditioner or heat pump compressor/condenser unit. As an added precaution, shovel sand or dirt to cover the dampened coals to smother any remaining embers. Are there any codes or standards for the foundation for a heat pump? Here is an adapted (reformatted) quote of clearance requirements from a Carrier 24ANA Infinity Series Air Conditioner of 2-5 nominal ton size A/C equipment installation manual and the Lennox Elite® Seroes XC13 condensing units and other condenser installation instruction documents that you can read inPDF form at REFERENCES. Your fire must never be left unattended and the fire must be extinguished completely before leaving. together will probably not receive enough cool air flow to function properly. Top: A minimum of ½', and ideally 1 full inch of clearance above. If you're talking about privacy walls or screens at patios or decks, say at a condo, the A/C compressor condenser side-clearance distances specified by the manufacturer (and cited above) need to be respected. A rule of thumb is to assure that there is at least 4 ft. above the A./C compressor/condenser unit. but in my opinion, if the unit is right below an operable window you won't like the noise nor the blast of hot sir out of the condenser unit top, especially if the window is open. Great article. Build a campfire surround with rocks to contain your campfire. Since an exit stair or door wants at least a 3-foot landing or clearance in the direction of travel it seems to me that'd be a bare minimum and 48" or more makes more sense; imagine trying to bring a couch into a building having to lift it over the AC unit.
Scrape away grass, leaves or needles down to the mineral soil. Access and download campaign materials. - AC Unit Clearance space to a fence: Tuti Teach children how to STOP, DROP and ROLL should their clothing catch on fire. This will allow for plenty of room for furniture and traffic space. The manufacturer probably specifies a minimum number of feet of clear space above the compressor/condenser unit to avoid restricting its intake or more often outflow. As little as 1 second contact with a 70°C (158°F) campfire can cause 3rd degree, full thickness burns. The safest way to extinguish a campfire is with water. but the installation and operation manual for your specific HVAC condenser unit brand and model would of course be the best authority as their data could differ. Some air conditioner manufacturers such as McQuay provide a refrigeration piping guide that gives complete, detailed guidance and charts on refrigerant line sizing (diameter) as a function of length of run. It's true that blocking air flow across a heat pump will limit its effectiveness, but I'd be surprised if that showed up as a difference between rooms in the home. Bill Secure all lighters and matches and keep them out of children’s reach. But most-likely you won't find an explicit clearance distance from the gas fireplace heater vent cap to an air conditioning compressor. That's to avoid the heat or the air demand from one unit from impacting the other's operating efficiency and life expectancy. How far must the AC unit be set back from the property line between us? Ensure that a responsible adult is monitoring the campfire at all times. Really? Stack extra wood upwind and away from the campfire so that sparks from the campfire cannot ignite your woodpile. Watch the wind direction to ensure sparks aren’t getting on flammable materials. Watch out: Separately, if a different compressure unit desigh caused the unit's exhaust to blow into the gas heater exhaust vent, that could prevent safe venting of exhaust gases. The smell is unpleasant for you and your neighbours, and may attract animals to your campsite. Also, keep a shovel and bucket of water nearby at all times.

If a fire starter is required, use only proper lighting fluid and use the lighting fluid sparingly. For example, Lennox air conditioner installation instructions for the compressor/condenser unit typically require 48" of clear space above the unit. The cross - sectional area of the duct would be the same as the area of the existing factory discharge opening and would be a straight vertical run with no offsets. 2015/11/06 Tom said: what is the minimum required distance between a home A/C condenser unit and a fill valve for a home heating oil tank?
Keep all combustible materials, including flammable liquids, propane cylinders, lighting fluid, etc. However it's rather likely that the manufacturer's instructions and do require that the pad be level and that the condenser unit be installed with sufficient slack or extra material in wiring and refrigerant piping that shukd the unit move slightly the wiring and refrigerant piping will not be disturbed, broken, or made to leak or made unsafe. NEC ARTICLE 110 Requirements for Electrical Installations, I. General110.1 Scope.This article covers general requirements for the examination and approval, installation and use, access to and spaces about electrical conductors and equipment; enclosures intended for personnel entry; and tunnel installations. All it takes is one spark for things to go wrong. The article above gives typical condenser clearance distances, 72" (Canada) or 36" (U.S.) to a mechanical air supply inlet, & 3' (91cm) above if within 10' (3m) horizontally. I can't tell fro your photo but if the back side of that condenser unit is expected to take in or exhaust air it may be blocked by the solid fencing. Any recommendation on the length? (A) Working Space. This is not quite correct. You should find the installation instructions for your specific brand and model gas fireplace and therein you should find the specific clearance distances given by the manufacturer. A campfire put out with water is reduced to 50°C (122°F) within 10 minutes of applying the water and reduced to 10°C (50°F) after 8 hrs.
Mike, Your condenser location 3 ft out from the wall and presumably not blocked for working space nor air movement can be acceptable, for condenser unit operation and maintenance, General answer is that the best Authority is the manufacturer's installation instructions for your particular heat pump or air conditioner brand and model.
