How Gelco Products Fail - and How We Fix Them

• Gelco gas log sets with standing pilots (GL-18, GL-24 series) often develop thermopile voltage drop after 8-12 years in Philadelphia’s hard-water service area. The pilot stays lit but won’t open the main gas valve. We test millivolt output at the valve, clean the pilot orifice with a proper port cleaner (never a wire), and replace the thermopile with an OEM Robertshaw or a tested equivalent. If the valve itself is sticky, we replace it with the exact White-Rodgers or SIT match - no universal substitutes that void your burner warranty.
• Gelco fireplace inserts (VSI-32, VSI-38 wood-burning units) suffer cracked refractory panels from thermal shock, especially in West Philly and Germantown rowhouses where owners crank them hard after work. Hairline cracks we can seal with HeatShield refractory sealant; panels separated by more than a nickel’s width get replaced with Gelco-specified 1.25-inch refractory board, not the thinner aftermarket sheet that bows in two seasons.
• Gelco direct-vent gas fireplaces (GDV-40, GDV-50 series) get draft interference from Philadelphia’s tight lot lines and shared flue conditions in older neighborhoods. The pressure switch trips, the unit shuts down, and a less experienced tech replaces the switch three times. We check actual draft with a digital manometer, verify the termination cap clearance from the neighbor’s soffit, and fix the root cause - often a partially blocked vent run or an improper initial installation that didn’t account for the rowhouse stack effect.
• Gelco chimney-top dampers (CTD series, common on pre-fab wood fireplaces) seize in the open position after years of creosote glazing and freeze-thaw. The cable frays, the cast-aluminum frame corrodes at the pivot pin, and homeowners lose conditioned air all winter. We disassemble, media-blast the frame, lube with high-temp graphite, and replace the cable with stainless aircraft wire. When the frame is too far gone, we install a new Gelco CTD or a Lock-Top equivalent with the same mounting footprint - no masonry cutting needed.
• Gelco firebox weld seams in older prefab units (1985-2005 production) rust through at the floor-to-sidewall joint, especially where Philadelphia’s humid summers let condensation collect behind rusted flashing. We cut back to sound metal, patch with 16-gauge aluminized steel per NFPA 211, and seal with Furnace Cement rated to 2,000°F. For extensive floor rot, we document with photos and give a plain verdict: repair or replace the entire firebox. No hiding the truth to get the job.

Our Gelco Fireplace Services Process

1. 1
   You call, we answer. A live person at (866) 580-4069, 24 hours a day. We ask the model number if you have it, the symptoms, and schedule a window that day or next.
2. 2
   Level-2 camera inspection on arrival. Our tech arrives uniformed and background-checked, lays down runners, and inspects the firebox, venting, and chimney interior with a color camera. You see the photos on the tablet. We explain what we found and what it means - no jargon, no scare tactics.
3. 3
   Parts decision: OEM or quality aftermarket. For Gelco units, we stock common thermopiles, gas valves, refractory panels, and damper cables. If your part is obsolete, we source through our network or fabricate from DuraFlex or HeatShield materials that meet or exceed original spec. You get the choice and the price before we start.
4. 4
   The repair, done right. Most Gelco fireplace services take 2-4 hours. We test every gas joint with electronic leak detection, verify draft and spillage with a combustion analyzer, and run the unit through three complete cycles before we call it done.
5. 5
   Written documentation and the 90-Day Done Right Promise. You get photos, a plain-English report, and our guarantee in writing: if it’s not right, we come back. No paperwork to dig up, no arguing.
6. 6
   Cleanup and final walkthrough. We vacuum, remove runners, and show you what was fixed. The estimate price is the invoice price. Period.

Why Philadelphia Homeowners Call Hearthstone Chimney Co. of Philadelphia for Gelco Work

We’ve been working on Philadelphia chimneys since 1984. Carl Bridwell trained at Rosedale Technical College and spent the better part of two decades on ladders from Bella Vista to Allegheny West before building Hearthstone Chimney Co. into what it is now. We know Gelco units because we’ve repaired hundreds of them in this city’s actual houses - rowhouses with shared walls, Center City condos with zero clearance, stone farmhouses in the far Northeast with flues that haven’t been touched since the Reagan administration.

Our 90-Day Done Right Promise means what it says: in writing, no arguing. Our technicians are background-checked, uniformed, and carry the parts to finish most Gelco fireplace services in one visit. We also work with DuraFlex liner systems and HeatShield refractory products, so when a Gelco repair needs a companion fix, we’re not subcontracting or sending you elsewhere. A live person answers the phone 24 hours a day, 7 days a week. If it’s worth burning wood in, it’s worth knowing what’s above it.
