Fuel Delivery, Ignition Logic, and Mounting
A torch is a small appliance in a demanding position. It stands exposed, often at the end of a long gas run, frequently near a structure, and sometimes within reach of salt spray. Those four conditions drive every specification decision.
The sections below cover fuel sizing, how ignition systems differ, clearance to walls and structures, and what protects an orifice outdoors.
How Is the Gas Supply Sized for a Torch Run?
A single torch draws modestly. A row of them at the end of a long run is a different calculation entirely.
Natural gas and propane each impose their own constraints:
- Natural gas hinges on pipe bore measured over the whole distance, because pressure bleeds away along it
- Propane depends on tank capacity and on vaporization rate, which falls in cold weather
- Multiple torches total their demand, and the line has to carry the sum rather than the largest unit
Distance is what gets underestimated. Torches end up at boundaries and path ends, typically further from the meter than anything else installed. Pipe that feeds a nearby fire pit perfectly well can leave a torch starved well down the garden. What shows up is a short wavering flame, and the unit takes the blame.
Propane installations add a cold weather consideration. A tank has to vaporize liquid fast enough to meet demand, and that rate drops as temperature falls and as the tank empties. Several torches on one small tank is the combination that disappoints in January.
How Do the Ignition Systems Differ?
Three approaches exist, and they suit quite different situations.
Manual lighting is the simplest and has nothing to fail. It suits a single torch within easy reach of someone holding a lighter. A standing pilot holds a small flame ready so the main burner catches on demand. That spares the walk to each unit, in exchange for burning a little fuel around the clock. Electronic ignition lights on command from a switch or remote, proves the flame electrically, and shuts the gas off if that proof is lost.
Automatic reignition is the feature that matters on exposed sites. Wind extinguishing a torch is routine rather than exceptional, and a unit that relights itself keeps working where one that simply shuts down does not. That capability belongs to electronic systems specifically.
Brand ranges differ in which they offer. Options across Tempest Torch, HPC Fire, Fire by Design, and The Outdoor Plus cover manual through fully automated, and the control approach is often the deciding factor between them.
Can Low Voltage Wiring Share a Trench With Gas?
Electronic torches need power as well as fuel, and both frequently run to the same post.
Codes govern how far apart the two services stay, and those distances come from the local authority rather than from a product catalogue. What holds everywhere is that the answer has to arrive before the trench does. Pulling apart a buried line and a buried cable later means digging the same ground twice.
Three practices keep an installation straightforward. Running each service in its own conduit at the prescribed separation is the baseline. Bringing them up into a post through separate entries rather than a shared opening keeps the separation intact where it matters most. Leaving the gas joint reachable once the cable is in place also matters, so that testing one service never requires disturbing the other. The installing trades and the inspector settle the figures.
What Clearance Does a Torch Need From a Wall?
A torch places open flame at head height, often beside a structure, which makes clearance a code matter rather than an aesthetic one.
Three directions apply. Horizontal distance to a wall or post protects the surface from radiant and convective heat. Vertical distance above the flame protects soffits, eaves, pergola beams, and overhanging branches. And distance to anything that moves, including awnings and shade sails, has to account for where that thing goes when the wind blows rather than where it sits still.
Combustible surfaces need the full published figure. Timber siding, painted trim, and vinyl are all affected by sustained heat well below ignition temperature, with discolouration and distortion appearing long before anything worse. Non combustible masonry tolerates more, though the manufacturer figure still governs. Where a desired position cannot provide the distance, moving the torch is the answer rather than reducing the clearance.
How Are Gas Orifices Protected Outdoors?
An orifice is a precisely sized opening in an exposed appliance, and anything that partially blocks it changes the flame.
Insects cause most of it. The odorant added to gas attracts spiders especially, and they build inside burner ports and pilot tubes. Service literature treats this as expected behaviour rather than a curiosity. Windblown grit and plant debris finish the job on open sites.
Three measures reduce the exposure. Covering a torch when it will be unused for an extended period keeps the opening sealed against nesting. Screens fitted where the manufacturer provides them block access without restricting flow. And periodic inspection catches a partial blockage while the symptom is still a slightly uneven flame rather than a failure to light.
Coastal sites add salt to the list. Rinsing the housing and exposed hardware with fresh water clears salt before it reaches fasteners and burner parts. It counts for more here than on a sheltered appliance, since a torch stands in whatever arrives.
What Mounting Methods Are Available?
Torch mounting divides into permanent and surface fixed, and the ground conditions usually decide.
In ground post mounting sets the unit in concrete, which gives the most stable result and the least flexibility. Depth and footing dimensions follow the manufacturer specification and local frost depth, both of which matter because a footing above the frost line will move. Surface mounting fixes a base plate to an existing slab or deck, which is faster and reversible, and depends entirely on the fixing being appropriate to that surface. Wall and pier mounting attaches a unit to existing structure, which removes groundwork but transfers load into whatever it is fixed to.
Each puts different demands on the fuel and power routing. A post mounted unit needs both services brought up inside the post. A wall mounted unit needs them arriving at the mounting point. Settling the mounting method first is what makes the service routing straightforward, since the reverse order rarely works. The wider outdoor fire features category covers ground level alternatives where overhead clearance is the limiting factor.
What Keeps a Flame Stable in Weather?
Wind is what defeats most torch installations, and the response is partly in the product and partly in the position.
Enclosed designs shield the flame behind glass or within a housing, which holds it in conditions that would extinguish an open burner. Internal airflow geometry does as much work as the shield itself. A housing that steers air around the flame along a controlled path holds it where a plain windbreak would not. Automatic reignition covers the remainder.
Position contributes independently. A torch at the exposed corner of a terrace faces conditions a torch against a sheltering wall never sees. Where several units are planned, placing the more exposed positions carefully, or specifying enclosed designs for those, costs nothing at the planning stage.
