Gas Service Installation

From new appliances to full service upgrades, gas work demands experience and precision. John Shelton Plumbing provides safe, code-compliant gas service installation for homes and businesses throughout the Alle-Kiski Valley. Our licensed, insured technicians deliver clean routing, secure connections, and correct sizing—so furnaces, water heaters, ranges, fireplaces, and pool heaters operate reliably and efficiently.

What a Gas Service Installation Covers

A new or upgraded gas service connects your property to the fuel source and distributes gas safely to equipment. Depending on your goals, your project may include:

• Service line routing and secure tie-ins from the meter to your building
• Proper sizing for total connected load and future appliances
• Shutoff valves at accessible, clearly labeled locations
• Venting and combustion air checks for equipment safety

When to Consider a New Gas Service

• Adding new equipment: Converting to a tankless water heater, upgrading furnaces, or adding a gas fireplace or range.
• Low gas pressure or nuisance lockouts: Appliances struggling to stay lit during peak demand.
• Remodels or expansions: New kitchens, additions, or commercial build-outs that increase total load.
• Older or pieced-together piping: Multiple add-ons over the years that need a clean, modern layout.

Our Safe, Proven Process

1) Load Review & Layout

We evaluate existing appliances and planned additions to size the service correctly. For commercial spaces, we account for operating schedules and simultaneous loads to maintain stable supply. If your project also needs new gas line routing inside the building, we plan it as one coordinated solution.

2) Code-Compliant Installation

We route piping in clean, protected runs with proper supports and approved fittings. Transitions and shutoffs are installed where they’re easy to access, clearly labeled, and leak-free. As a D.O.T.-qualified gas contractor through our broader Gas Line Services work, we follow best practices on every job.

3) Testing & Commissioning

All work is pressure-tested and verified before appliances are brought online. We confirm flame characteristics, check for nuisance shutdowns, and review basic operation with you so you know how to safely use and shut down your gas equipment.

Appliances & Equipment We Commonly Serve

• Furnaces and boilers
• Traditional Water Heaters and Tankless Water Heaters
• Ranges, ovens, and cooktops
• Gas fireplaces and log sets
• Pool and spa heaters
• Commercial unit heaters and make-up air equipment

Why Correct Sizing Matters

Undersized lines cause low manifold pressure, ignition issues, and appliance lockouts. Oversized lines waste material and can complicate routing. We size services and branches to manufacturer specifications and local code so equipment runs as designed—especially during peak winter demand.

Upgrades & Conversions

Switching from electric to gas, adding a fireplace, or outfitting a commercial kitchen? We’ll review load, venting, and combustion air requirements and configure the most efficient, safe solution. If you’re pairing a new tankless unit with additional appliances, we’ll map a path that supports both performance and future expansion.
