Fireplace Gas Logs in Pasadena: Written Report, Licensed Technicians

The homeowner called us on a Tuesday in October. She'd bought a 1923 Craftsman bungalow near the Arroyo Seco corridor the previous spring, and the original brick fireplace had been sitting idle since she moved in. She wanted gas logs installed before the holidays but had questions she couldn't get straight answers on. Was her old flue even safe to vent through? Did she need a vented or ventless set for a living room that small? And what about the gas line - her house still had the original stub-out behind the firebox, capped off decades ago. She didn't want to gut the original tile surround or change the look of the hearth. She just wanted to use her fireplace without worrying about carbon monoxide or cracking the historic masonry.

We hear versions of this call constantly from Old Pasadena and San Marino, where Craftsman-era homes dominate entire blocks. These fireplaces were built for wood. The fireboxes are often undersized by modern standards, the dampers are original cast iron with heavy rust, and the flue liners - if they exist at all - are unlined or lined with deteriorating clay tile. Dropping a gas log set into one of these without a proper assessment is a carbon monoxide risk. That's not a scare tactic. It's the reason we schedule a hands-on evaluation before recommending any gas log configuration, especially in homes built before 1940. If you're in a similar situation, a good first step is a professional gas fireplace cleaning to assess what you're working with.

We started with a CSIA-standard Level 2 inspection, which NFPA 211 requires whenever you change the fuel type in a fireplace. The camera scan showed exactly what we expected: the clay flue liner had two vertical cracks above the smoke shelf, and the damper plate was frozen in a half-open position. For a vented gas log set - which we recommended here because the room measured only 180 square feet with 8-foot ceilings - the damper needs to stay fully open at all times. We installed a damper clamp to lock it in place permanently. The cracked liner got a stainless steel reline to contain combustion gases. We selected a 24-inch ceramic gas log set rated at 35,000 BTUs, which matched the firebox dimensions without crowding the original firebrick walls. Ceramic logs hold heat longer and look more realistic than fiber alternatives, which matters when the fireplace is the visual centerpiece of a Craftsman living room.

The gas line required a new flexible connector from the existing stub-out to a safety shut-off valve mounted inside the firebox. We pressure-tested the line before lighting the set. The whole project took one full day. The homeowner kept her original tile surround, her original mantel, and gained a fireplace she can turn on with a match. If your Craftsman bungalow along the Arroyo Seco corridor or in Old Pasadena needs a similar setup - or if you're considering a broader fireplace remodel - Ashgard Chimney Sweep handles the inspection, gas line work, and installation as one project.
