Post Mount Gas Torches: What to Compare Before You Choose
Mounting shapes the whole experience. Choosing a post mount gas torch means weighing its BTU rating, flame protection, shutoff features, ignition, post dimensions, and mounting configuration against your space. No single specification tells the whole story.
This guide explains what each specification means, how to compare torches against your site, and where HaloFire's post-mounted and tall gas torches fit.
Key Takeaways
- BTU/hr measures heat input, not flame quality. Compare it alongside burner design and the effect you want.
- Flame protection and gas shutoff are separate features. Check exactly what each torch includes.
- Measure the post, base, and surrounding area before choosing. Dimensions affect both fit and circulation.
- Electronic ignition makes lighting simple. Check the control options and power requirements for the exact model.
- Match the mounting style (post, in-ground, wall, or freestanding) to the space and the gas route.
BTU Ratings
BTU per hour describes a gas torch's heat input. It's useful for sizing the gas supply and estimating fuel use, but it doesn't measure how the flame looks. Burner design, orifice sizing, inlet pressure, regulator capacity, piping, run length, and available gas volume all shape performance. If the supply doesn't meet the torch's requirements, it won't perform as intended.
When comparing torches, record these from each product's documentation:
- BTU input: the rated input for the fuel configuration you'll use
- Flame purpose: whether the torch will mark an entrance, define a path, or create a focal point
- Supply conditions: the fuel and supply requirements versus your planned connection
- Operating pattern: how long and how often you'll run it
Estimating fuel use
Multiply the torch's BTU/hr by your hours of use. For natural gas, one therm equals 100,000 BTU, so a torch rated at 11,000 BTU/hr uses about 0.11 therm per hour at full input. For propane, one gallon holds roughly 91,500 BTU, or about 0.12 gallon per hour for the same torch. Apply your local utility or propane rate for a cost estimate.
Flame Protection and Safety Shutoff
Flame protection and gas shutoff do different jobs, and neither replaces careful placement and supervision.
- Flame protection may mean a glass enclosure, a housing, or a hood over the flame. Check what the product's documentation actually describes. A glass enclosure doesn't make a lit torch safe for unsupervised children or pets.
- Gas shutoff may be manual, automatic, or both. Some gas appliances use flame sensing that interrupts gas flow if the flame goes out. Don't assume a control knob is an automatic shutoff, or that every torch includes flame-failure protection. Check the instructions.
Before choosing, confirm what the shutoff is, what activates any flame sensing, what the guard protects, and the torch's placement and clearance requirements.
Plan an accessible manual shutoff valve for each fixture as part of the installation. If a torch behaves unexpectedly, appears damaged, or won't shut off as directed, stop using it and follow the manufacturer's troubleshooting instructions. Never bypass a sensor or modify a guard.
Post and Base Dimensions
Measure the full installation area before choosing: the post, the base, and the flame position.
- Post height: Compare it with windows, seating, and sightlines.
- Base footprint: Check it against paving joints, planting edges, and walking routes.
- Nearby features: Note the doors, steps, furniture, and landscaping around it.
- Visual alignment: Consider how the post lines up with columns, fences, and other vertical elements.
Mark the actual footprint on the ground before deciding. A torch that looks right from across the yard can still narrow a path or crowd a doorway. Next to outdoor dining, check that it doesn't pinch the route between the table and an exit.
Ignition
Electronic ignition lights the flame at the press of a button or the flip of a switch, with no reaching in with a lighter. Some systems also allow smart switch or phone control.
Compare ignition options by:
- Operator access: Can you reach the control comfortably from the patio or path?
- Startup steps: What's the exact lighting sequence?
- Power needs: What powers the ignition, and how is it maintained?
- Service access: Can ignition components be reached without disturbing the mount?
Ignition and safety shutoff are separate functions. A spark starts the flame; it doesn't mean the torch detects flame loss or shuts off the gas.
Mounting Configurations
| Configuration | Where it works | Gas routing |
|---|---|---|
| Post-mounted | Walkways, steps, garden borders, deck perimeters | Supply runs up through or alongside the post |
| In-ground tall torch | Pool edges, terraces, perimeters | Supply runs below grade to the torch |
| Wall-mounted | Entrances, columns, walls where floor space matters | Supply runs through or along the wall |
| Freestanding propane | Anywhere a gas line can't reach | Self-contained cylinder, no gas line |
Before choosing a configuration
- Confirm the mounting type matches the product's intended installation.
- Assess the surface or ground against the model's mounting requirements.
- Plan the gas route using the product's connection requirements and local rules.
- Preserve access to the controls, ignition, and service points.
Mounting hardware, anchors, and gas connections aren't interchangeable between torches. Keep the product instructions with your site plan. Permanent gas connections should be completed by a licensed gas professional following the product instructions and local requirements.
HaloFire Post-Mounted and Tall Gas Torches
HaloFire designs gas torches with a spinning vortex flame that rises into a defined vertical column.
| Torch | Mounting | Key details |
|---|---|---|
| Vortek™ NG/LP Gas Torch | Post-mounted | Approx. 23 in tall, approx. 11,000 BTU/hr; published pressures 3.5 in W.C. (natural gas) and 11 in W.C. (propane); requires a rain cap for rain exposure |
| Hollywood™ Series | Post-mounted and tall configurations | Architectural gas torch, especially suited to planned gas rough-ins; requires a rain cap for rain exposure |
| Tempo™ Tall Torch | In-ground | Approx. 75 in tall, approx. 25,000 BTU/hr; rain cap included |
| Torrent™ Wall Mounted Torch | Wall-mounted | 24, 32, and 48-inch glass heights; built-in hood covers the flame from rain |
| Torrent™ Stand-Alone | Freestanding | Approx. 78 in tall, concealed 20-pound propane cylinder, no gas line; built-in hood |
Every HaloFire gas torch has electronic ignition. Most are available with push-button or smart switch and phone control; the Torrent™ Stand-Alone uses a push-button switch.

Make the Flame Part of the Design
Start with the flame's role: marking an arrival, lining a path, defining the deck's edge, or anchoring a focal point. Let that purpose guide the mounting style and placement, then compare the specifications against your site.
Bring your site plan and gas details to HaloFire, and find the torch that fits.
Frequently Asked Questions
What is a post mount gas torch?
An outdoor gas torch mounted on a post and connected to a natural gas or propane supply. Gas flows to a burner, where electronic or manual ignition lights the flame.
Natural gas or propane: which do post mount torches use?
Each torch is configured for a specific fuel. HaloFire's Vortek™ NG/LP is available in either. Choose the configuration that matches your supply, and don't assume a torch can be converted.
How much gas does a post mount torch use?
Multiply its BTU/hr rating by your hours of use. The Vortek™ NG/LP, at about 11,000 BTU/hr, uses roughly 0.11 therm of natural gas or 0.12 gallon of propane per hour at full input.
Do post mount gas torches work in the rain?
It depends on the model. The Vortek™ NG/LP and Hollywood™ need a rain cap for rain exposure. The Tempo™ comes with a rain cap, and Torrent™ models have a built-in hood.
What permits do outdoor gas torches need?
It depends on your jurisdiction and whether the torch connects to a permanent gas line. Check with your local building or fire department, and have a licensed gas professional complete the connection.
What maintenance do post mount gas torches need?
Follow the maintenance schedule in your torch's instructions. In coastal areas, rinsing metal and wiping glass more often helps protect the finish from salt.
What are the fire, burn, and carbon monoxide risks?
An open gas flame can cause burns or ignite nearby materials, and gas combustion produces carbon monoxide. Use gas torches outdoors only, never indoors or in enclosed spaces. Follow the placement and clearance instructions, and never leave a flame unattended. If you smell gas, don't light the torch; follow the product's emergency guidance and contact your gas utility.
