Gas Line Installation for Fire Pits: Safety, Cost & What to Expect on Long Island

A backyard fire pit transforms your Long Island outdoor space into a year-round gathering spot. Gas fire pits — whether a sleek modern fire table or a traditional stone fire pit with a gas insert — offer the ambiance of a wood fire without the mess, the smoke, or the need to haul firewood. But installing a gas line for a fire pit requires professional expertise. At Retro Hot Water & Heating, we handle gas fire pit installations across Nassau and Suffolk Counties safely, legally, and efficiently.

Natural Gas vs. Propane for Fire Pits: Which Is Better?

You have two fuel options for a gas fire pit: a propane tank or a permanent natural gas connection. Here’s how they compare for Long Island homeowners:

Propane Fire Pits

Propane fire pits are portable and easy to set up — you simply connect a standard tank. However, propane runs out, requires tank storage, and costs more per BTU than natural gas. On Long Island, where many homes already have natural gas service for heating and water heating, propane for outdoor features is often a short-term solution.

Natural Gas Fire Pits

A natural gas fire pit connected directly to your home’s gas line provides unlimited fuel on demand. No tanks, no refills, no running out mid-evening. Natural gas is also cleaner-burning and less expensive than propane over time. If your home has natural gas service — for your boiler, water heater, or range — adding a fire pit line is a logical and cost-effective upgrade.

If you’re currently on oil heat and are considering making the switch, our oil-to-gas conversion services can be a great starting point before expanding to outdoor features.

Safety: The Most Important Factor in Gas Fire Pit Installation

Gas fire pit installation involves working with pressurized natural gas lines — which is why it must be performed by a licensed professional. Safety considerations include:

  • Proper shutoff valve installation within reach of the fire pit
  • Correct pipe sizing to ensure steady flame without pressure fluctuations
  • Underground line depth requirements to protect against accidental damage
  • CSST bonding to prevent lightning or electrical surge damage
  • Leak testing at every connection before ignition
  • Compliance with New York State fuel gas code and local Nassau/Suffolk regulations

A poorly installed gas line is a serious fire and explosion hazard. Never attempt to install or modify a gas line yourself, and always verify that any contractor you hire is a licensed master plumber or licensed gas fitter in New York State.

Safety first: All gas fire pit installations by Retro Hot Water & Heating include a full pressure test and inspection coordination before the system is ever activated.

How the Fire Pit Gas Line Installation Process Works

Step 1: Consultation and Site Evaluation

We visit your property, assess the location of your fire pit, measure the distance from your gas meter, evaluate existing gas supply capacity, and discuss your fire pit’s BTU requirements. Most residential gas fire pits range from 30,000 to 100,000 BTUs.

Step 2: Permit Application

Gas line work in Nassau and Suffolk Counties requires a permit. We apply on your behalf, submit required drawings, and coordinate the inspection schedule so you don’t have to navigate the bureaucracy alone.

Step 3: Trenching and Pipe Installation

We trench from your home’s gas supply to the fire pit location at the required depth. We install approved gas piping — typically CSST or black steel — with proper connectors, a shutoff valve at the fire pit, and all required protective fittings.

Step 4: Pressure Test and Inspection

The completed line is pressure-tested to verify zero leaks. The local building inspector then reviews the installation before the line is put into service.

Step 5: Connection and Startup

We connect the gas line to your fire pit’s burner system, test all controls and igniters, and walk you through safe operation and shutoff procedures.

What to Look for When Choosing a Fire Pit

Before we install your gas line, it helps to know what type of fire pit you’re connecting to. Popular options on Long Island include:

  • Fire tables — double as outdoor furniture with a recessed burner in the center
  • In-ground fire pits — custom-built stone or brick structures with a gas burner insert
  • Fire pit rings — circular inserts installed in an existing fire pit structure
  • Wall-mounted fire features — vertical fire features for patios and outdoor living walls

We can work with virtually any fire pit design, as long as the burner unit is rated for natural gas (not propane-only).

Connecting Your Fire Pit to Your Broader Gas System

Many Long Island homeowners use a single gas line project as an opportunity to extend natural gas service to multiple outdoor features. If you’re already running a line for a fire pit, it may be cost-effective to extend service simultaneously to a BBQ or generator.

Our BBQ and outdoor kitchen gas line installation service can be combined with your fire pit installation for cost savings on trenching and permitting.

If you have a pool, consider adding a pool heater gas line in Nassau/Suffolk County at the same time to maximize your investment.
