What Is the ICC G34-N Examination?

The G34-N examination is associated with the ICC Contractor and Trades testing program. Participating licensing authorities may use it as part of their journeyman gas pipe fitter qualification process.

The examination may evaluate a candidate’s ability to:

• Interpret fuel-gas code requirements
• Calculate connected appliance demand
• Select gas pipe and tubing sizes
• Identify approved materials and joining methods
• Install valves and pressure regulators
• Apply pressure-testing requirements
• Evaluate combustion-air provisions
• Apply appliance venting requirements
• Recognize unsafe gas installations

Passing the exam does not automatically issue a license. Candidates must also satisfy the requirements of the applicable state, county, city, or municipality.

Confirm Local Licensing Requirements

Before purchasing materials or scheduling the exam, verify:

• Whether the licensing authority accepts G34-N
• The required fuel-gas code edition
• The current approved reference list
• The examination format and testing time
• The passing-score requirement
• Rules for tabs, highlighting, and notes
• Required gas-fitting experience
• Application and examination fees
• License renewal requirements

Common G34-N Study Areas

• Fuel-gas definitions
• Natural gas and propane characteristics
• Gas demand calculations
• Pipe and tubing sizing
• Approved piping materials
• Joints, fittings, and connectors
• Pipe support and protection
• Valves and regulators
• Pressure testing and leak detection
• Purging procedures
• Combustion air
• Chimneys and vents
• Gas-fired appliances
• Permits, inspections, and safety

Gas Demand and Pipe Sizing

Gas piping must be sized to deliver enough fuel to all connected appliances while maintaining the required operating pressure.

Pipe size may depend on:

• Fuel type
• Gas pressure
• Permitted pressure drop
• Gas specific gravity
• Pipe or tubing material
• Total connected demand
• Developed pipe length
• Branch arrangement

Candidates should practice adding appliance input ratings, converting BTU per hour when necessary, selecting the correct sizing table, and choosing a pipe size with sufficient capacity.

Longest-Length Method

The longest-length method commonly uses the distance from the point of delivery to the most remote outlet when sizing system sections.

A practical process includes:

• List each connected appliance
• Determine each appliance input rating
• Calculate the demand carried by each pipe section
• Measure the longest applicable run
• Select the correct fuel, pressure, and material table
• Choose a pipe size that meets or exceeds the required capacity

Approved Piping Materials

Gas piping materials must be approved for the fuel, pressure, environment, and installation method.

Materials may include:

• Steel pipe
• Copper or copper-alloy tubing where permitted
• Corrugated stainless steel tubing
• Approved polyethylene piping for underground use
• Listed fittings and transition fittings
• Listed appliance connectors

Candidates should identify the material before determining the permitted joining, support, protection, and testing methods.

Pipe Support and Protection

Gas piping must be supported to prevent sagging, movement, vibration, and stress on joints.

Study subjects may include:

• Horizontal support spacing
• Vertical support
• Protection through framing members
• Protection from vehicles and equipment
• Underground burial and corrosion protection
• Rooftop supports
• Tracer wire for underground plastic piping
• Protection at building entrances

Valves and Pressure Regulators

Gas piping systems use shutoff valves and pressure regulators to control gas flow and protect downstream equipment.

Candidates should review:

• Building shutoff valves
• Appliance shutoff valves
• Emergency shutoff valves
• Service regulators
• Line pressure regulators
• Appliance regulators
• Regulator venting
• Overpressure protection
• Accessibility and identification

Pressure Testing and Leak Detection

New and altered gas piping must be tested before concealment or operation.

Important preparation topics include:

• Approved test media
• Test pressure
• Test duration
• Gauge range
• Isolation of appliances and regulators
• Inspection of exposed joints
• Repair and retesting
• Approved leak-detection solutions and instruments

Open flames should never be used to locate a gas leak, and oxygen should not be used as a pressure-test medium.

Combustion Air

Gas-fired appliances require sufficient air for combustion, dilution, and ventilation.

Combustion-air requirements may depend on:

• Total appliance input
• Room volume
• Building construction
• Indoor openings
• Outdoor openings
• Horizontal or vertical ducts
• Mechanical air systems
• Louver and grille free area
• Competing exhaust equipment

Candidates should identify the combustion-air method before calculating required openings or airflow.

Appliance Venting

Venting systems carry combustion products safely outdoors.

Study subjects may include:

• Natural-draft appliances
• Fan-assisted appliances
• Direct-vent appliances
• Vent categories
• Type B gas vents
• Chimneys
• Vent connectors
• Common venting
• Vent slope and support
• Clearance to combustibles
• Vent termination

Manufacturer installation instructions may add appliance-specific requirements to the general code provisions.

Gas-Fired Appliances

Common appliances that may appear in G34-N preparation include:

• Furnaces
• Boilers
• Water heaters
• Ranges and ovens
• Clothes dryers
• Fireplaces and decorative appliances
• Unit heaters
• Pool heaters
• Standby generators
• Commercial cooking equipment

For each appliance, review gas demand, shutoff valves, connectors, sediment traps, combustion air, venting, clearances, and access for service.

Code-Book Navigation

A reference-based exam still requires fast and accurate navigation.

A practical lookup method includes:

• Read the complete question
• Identify the main technical keyword
• Determine whether the question concerns piping, testing, combustion air, venting, or appliances
• Use the index or table of contents
• Read the complete section
• Check definitions, tables, notes, and exceptions
• Confirm that the rule applies to the stated fuel and pressure

Recommended Study Plan

• Review fuel-gas terminology
• Practice gas demand calculations
• Practice natural gas and propane pipe sizing
• Review materials, joints, and support requirements
• Study valves and regulators
• Review pressure-testing procedures
• Practice combustion-air calculations
• Study venting systems and appliance categories
• Complete timed practice questions
• Review every missed answer in the reference book
