Gas words, in plain English No trade vocabulary needed.

Demand / load: How much gas the equipment needs. An appliance label gives its fuel input in BTU per hour; add the relevant appliances when assessing a shared pipe.
BTU/h / input rating: British thermal units per hour: the rate of fuel energy going into an appliance. Heat output is what it delivers after losses, so use the input rating for gas-supply calculations.
Flow / CFH: How much gas passes a point over time. CFH means cubic feet per hour. A cubic foot is a volume, like a box one foot on each side.
Pressure / pressure drop: Pressure is the push on the gas. A pressure difference moves it along a pipe. The reduction in pressure along the route while gas flows is called pressure drop.
Capacity: How much gas a pipe, meter or other part can deliver at the specified pressure. The connected appliances determine how much capacity is needed.
Branch / upstream / downstream: A branch takes gas from a shared route to part of the system. Upstream means toward the supply; downstream means in the direction gas travels toward the appliances.
Meter / regulator: The meter measures gas use. A regulator controls pressure.
Shutoff / sediment trap: A shutoff is a valve that stops supply to a section. A sediment trap is a capped pocket arranged to catch debris before it reaches an appliance’s gas controls.
Inlet / manifold: The inlet is where gas enters an appliance. The manifold distributes it to the burners inside. Pressure requirements at these two places can differ.
Combustion air / venting: Combustion air is air needed to burn fuel. Venting carries the resulting exhaust away.
Clearance / access: Clearance is required space around equipment or piping. Access means being able to reach a part for inspection or service.
Code / commissioning: Code means installation rules adopted for the job’s location. Commissioning means checking and starting equipment according to its instructions, then confirming that it operates as required.

LEARN THE SYSTEM / NO EXPERIENCE REQUIRED

Gas lines,
one idea at a time.

Follow the gas through a home, change example appliance demands, or translate pressure units. Each lesson explains what the result means.

Follow the gas through the whole building.

The meter is outside. Inside, shared piping divides into branches for different appliances. Each appliance has a shutoff. Explore those connections together, then trace any appliance back to the supply.

THE WHOLE HOME / INSIDE & OUT

One supply.
Every connection.

11 appliances. One connected building.
Choose a part, inspect its shutoff, and trace its gas supply.

Preparing the connected building…

Click an appliance or shutoff. Every appliance stays in the building.

House gas pipingAppliance shutoffsSelected supply route

SELECTED IN THE BUILDING

Outside the home

Utility service

The underground utility line brings gas to the meter installation outside. This is the supply for the whole building, before it divides into appliance branches.

Why it matters

The utility confirms its available service. A new appliance can require review of the meter and supply as well as work on your house piping.

Outside · utility equipment

Meter service shutoff

This valve is at the meter installation. It controls the supply to the whole system beyond it. It is different from the smaller shutoff serving one appliance.

Why it matters

Identify the equipment without operating it. If you suspect a leak, leave and call 911 and Enbridge from a safe place. Do not try to turn gas valves on or off.

Outside · pressure control

Utility regulator

The regulator reduces and controls the pressure of gas entering the meter installation. Pressure means the push that moves gas through the pipe.

Why it matters

The meter measures gas use, and the nearby regulator sets the delivery pressure. A house using higher-pressure distribution may have additional regulators before its appliances.

Outside · measures gas use

Exterior gas meter

The meter measures the gas passing into the property’s piping. In this building it is outside, beside the utility regulator and service shutoff.

Why it matters

A meter has a limit to how much gas it can deliver under its specified conditions. Adding equipment can require a meter review, even when a nearby pipe connection is available.

From outside to inside

Entry through the wall

After the meter, the customer piping enters the building through the exterior wall. The cutaway exposes that transition so you can follow it.

Why it matters

Protection at the wall keeps sharp edges and building movement from damaging the pipe. Weather sealing closes the gap around the entry, and nearby supports keep its weight off that opening.

Inside the building

Shared piping & branches

The larger shared route supplies smaller routes called branches. Each branch takes gas to equipment in a room or outside. The model reveals piping that could be concealed in a real house.

Why it matters

Adding an appliance increases demand in the shared pipes feeding it. Follow the route back to the meter and include the other appliances supplied along that route.

One appliance at a time

Appliance shutoffs

Each yellow-handled valve in this model marks an appliance shutoff. It closes the supply to the appliance it serves. Click a valve to see which appliance it serves.

Why it matters

Each appliance’s shutoff controls its gas branch and needs to remain reachable after cabinets or equipment are installed. Select “Find its shutoff” to trace that relationship.

After the appliance shutoff

Sediment traps

A sediment trap is a short, capped pocket below a change in direction near an appliance. It helps catch debris before it reaches the appliance’s gas controls. Installers sometimes call it a drip leg.

Why it matters

This model shows sediment traps at the heating equipment, water heaters, fire pit, pool heater and generator. A trap collects debris before it reaches gas controls. A drip has the related job of collecting liquid in gas piping.

Kitchen

Kitchen range

The range uses gas for cooking. Its branch ends at an appliance shutoff and the final connection. A cooktop is a related appliance without the oven.

Why it matters

A replacement model can have a different fuel demand. The installer checks its instructions, supply and final connection together.

How to read this cutaway

The meter and utility equipment sit outside. Open walls reveal the shared piping and branches to eleven gas appliances. Choose one to trace its supply or find the yellow handle on its shutoff.

This teaching model simplifies pipe lengths and connections to keep the routes visible. The generator trace reveals its buried branch. Capped sediment traps appear at the heating equipment and other illustrated appliances that use them. IFGC §408.4 explains the appliance exceptions.

What changes when you add another appliance?

Enter appliance input ratings to see their combined demand. BTU/h means British thermal units per hour—the fuel energy an appliance needs. The starting values are practice numbers.

Example appliance A · BTU/hExample appliance B · BTU/hNew example appliance · BTU/h

Set an unused example to 0. Each entry accepts 0–10,000,000 BTU/h.

TOTAL EXAMPLE DEMAND ON THE SHARED PIPE

140,000 BTU/h

40,000 + 100,000 + 0 = 140,000 BTU/h. The shared pipe serves all three example branches.

The total is the fuel demand on the shared pipe. Pipe sizing combines this demand with the route length, piping material, available pressure and the pressure needed at the appliances.

This lesson assumes all listed appliances could use their full rated fuel input at the same time. Use the total with the supply conditions, material and route in a pipe-capacity assessment.

Work through a heater replacement and an added grill ↗

Same pressure. Different units.

Translate a pressure value without changing what it means. psi means pounds-force per square inch. “Ounces” means ounces-force per square inch. inWC means inches of water column, another way to express pressure.

Example pressure valueUnit of that value

Accepts 0–1,000,000. For an appliance pressure setting, use the value in its installation manual.

EQUIVALENT PRESSURE

4 oz/in² = 0.25 psi = 6.92 inWC

All three values describe the same pressure. Converting units lets you compare a manometer reading with an appliance specification. Match the test point and operating condition stated in the manual.

Show the conversion and rounding

1 psi = 16 oz/in² ≈ 27.68 inWC. Convert the entered value to psi, then multiply by 16 or 27.68 for the other units. Outputs are rounded to six significant digits. The units retain the same zero reference. For example, a gauge reading compares with surrounding air pressure; this calculation preserves that reference while converting the unit.

START WITH THE APPLIANCE

Where is the
new line going?

Send the appliance model and where you want it. We use its fuel demand and the route back to the meter to plan the line.

01 / KITCHEN & LAUNDRY

Gas lines for stoves & dryers

A gas range is a stove with an oven; a cooktop has burners without an oven. For either—or a gas dryer—we assess the supply, shutoff, connection and access. Share the new model even when an old appliance used the same location.

Stove & dryer connections explained ↗

02 / OUTDOOR LIVING

Gas lines for grills & fire pits

Natural-gas piping for a BBQ, fire pit or patio heater. The appliance’s fuel type, outdoor location and any buried route belong in the plan from the start. Send the model and tell us whether the yard or patio is already finished.

Repair & restoration explained ↓

CHECKING THE EXISTING SUPPLY

Will the existing line
handle the new appliance?

We trace the route to the meter and add up the demand of the appliances sharing each section. That shows which parts of the piping will carry the added gas.

01

The utility supply

The utility confirms available service and how much gas the meter can deliver when a change is needed.

02

Your house piping

The installer checks the route, material, pressure and appliances sharing each section.

03

The appliance

The model’s instructions give its fuel input and the pressure needed where gas enters the appliance.

BTU: how much fuel?

BTU stands for British thermal unit, a measure of heat energy. An appliance’s input rating in BTU per hour describes its fuel demand. Adding the input ratings shows the demand on shared piping.

Pressure: how it is supplied

Pressure is the push that moves gas through the piping. The supply must maintain the appliance’s specified inlet pressure while equipment is running.

Branch: a route off the main pipe

A branch carries gas to part of the system. It may serve one appliance or several. Adding equipment means checking every shared section back toward the meter.

Black iron, CSST and an appliance connector—what is the difference?

Black iron is the common name for rigid steel gas pipe. CSST means corrugated stainless steel tubing: flexible building piping covered by a protective jacket. A short appliance connector makes the final connection to an appliance. Listed arc-resistant CSST systems such as FlashShield+ eliminate the manufacturer’s extra dedicated bonding-wire requirement. Standard gas-piping electrical bonding still applies, and a system containing conventional CSST still needs the extra bond.
