How Gelco Products Fail - and How We Fix Them

• Gelco gas fireplace inserts (GI-series): The pilot assembly on early GI-550 and GI-750 units collects condensation from Chelmsford’s freeze-thaw cycles, leading to intermittent ignition or a pilot that won’t stay lit. We clean the orifice with a calibrated reamer, replace the thermopile if voltage has dropped below 325 mV, and seal the burner pan to stop moisture migration. OEM pilot assemblies are available, though we’ve had equal longevity with SIT aftermarket kits when the bracket geometry matches.
• Gelco wood-burning fireplaces (Pre-fab models): The refractory panels in the firebox develop hairline cracks after 8-12 seasons of thermal cycling, especially when homeowners burn green hardwood or overfire during January cold snaps. We source Gelco-spec 1.25-inch refractory board or upgrade to HeatShield Cerfractory foam for panels that have lost more than 30% surface integrity. The repair is documented with before-and-after photos.
• Gelco chimney-top dampers (CTD series): The stainless cable can seize inside the conduit after years of creosote dust accumulation, leaving the damper stuck open or closed. We don’t just lubricate and hope; we pull the cable, inspect for fraying, and replace the entire assembly if strands are compromised. Chelmsford’s red oak and maple produce sticky creosote that accelerates this failure.
• Gelco direct-vent gas fireplaces: The co-axial vent terminal’s intake louvers clog with cottonwood seed in June and ice dams in February, causing rollout switches to trip or combustion air starvation. We disassemble the terminal, verify proper wall termination clearances per MA fuel gas code, and install a high-wind directional cap if the unit faces west toward the prevailing wind across Heart Pond.
• Gelco fireplace doors and frames: The tempered glass gaskets compress and harden after a decade, leaking room air into the firebox and killing draft on wood-burning units. We measure the exact channel width, since Gelco used two different extrusions depending on production year, and install either OEM rope gasket or a silicone-impregnated upgrade that outlasts the original in our experience.

Our Gelco Fireplace Services Process

1. 1
   Call and schedule. A live person answers, notes the Gelco model if you have it, and books a window. No app, no callback queue.
2. 2
   Arrival and diagnostic. Our technician arrives uniformed and background-checked, lays down floor protection, and begins with a Level-2 visual inspection. For gas units, we check manifold pressure, flame characteristics, and venting with a digital manometer and combustion analyzer.
3. 3
   Parts decision. If a component has failed, we show you the exact part and explain OEM versus quality aftermarket options. We stock common Gelco wear items; specialty orders arrive in 2-3 business days if needed.
4. 4
   The repair. We complete the work, test all safety controls, and verify proper operation. Gas units get a written combustion analysis printout. Wood units get a draft and smoke test.
5. 5
   Documentation and cleanup. You receive photos of the issue and the repair, a plain-English verdict, and an invoice that matches the upfront price. We leave the work area cleaner than we found it.
6. 6
   The guarantee. Every job is covered by our 90-Day Done Right Promise in writing. If it’s not right, we come back. No paperwork, no arguing.
