Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

How Gelco Products Fail - and How We Fix Them
- Gelco Vented Gas Log Sets - delayed ignition and sooting. The G4 and G5 burner assemblies use a fixed orifice that clogs with Lansdale’s mineral-heavy water vapor and seasonal dust. We see this in Ranchlands and Upper Gwynedd splits built 2015-2020. The fix is not a new log set. We pull the burner, ultrasonic-clean the orifice, check gas pressure at the manifold with a digital manometer, and replace the ember material if it’s fused. The camera doesn’t guess. Neither do we.
- Gelco Direct-Vent Inserts - failed blower motors and cracked refractory panels. The DV-36 and DV-42 series run blowers hard through Montgomery County’s shoulder seasons. Motor bearings dry out; the refractory cracks from thermal cycling when the blower fails and heat pools. We source OEM blowers through our Haven buying network or match spec with a sealed-bearing aftermarket unit that outlasts the original. Refractory panels are measured in-place, not eyeballed, because Gelco changed the DV-42 mold in 2018 and the pre- and post- panels don’t interchange.
- Gelco Wood-Burning Fireplaces - smoke chamber deterioration and damper seizure. The SC-36 and SC-42 units installed in Lansdale’s 1990s colonials near the Merrick Road corridor have parged smoke chambers that flake with age. The throat damper rusts in place from condensation, not use. We parge with Chamber-Tech 2000 or spec a lock-top damper if the throat is too far gone. Corrine’s crew has done enough of these to know which SC-36s left the factory with the narrow firebox depth that makes retrofit inserts a nightmare.
- Gelco Fireplace Inserts - liner connection gaps and creosote in the transition. The insert-to-liner adapter on older Gelco wood inserts was a slip-fit collar that gaps with thermal expansion. Class III creosote, the hardened, tar-like stuff, packs that gap and restricts draft. We camera the full liner length, remove the insert if needed, and reseat with a proper Gelco-compatible adapter or fabricate a stainless transition. We document the creosote class on the photo report so you know why we recommended what we did.
- Gelco Gas Fireplaces - thermopile degradation and valve timing drift. The SIT 820 valve paired with many Gelco units loses millivolt output as the thermopile ages, causing intermittent pilot dropout. Worse, the valve’s solenoid can hang open if debris passes the fine mesh screen. We test thermopile output under load, not open-circuit, because a 750mV reading that drops to 250mV when the main valve opens is a failed unit dressed up as good. We replace with OEM or a Robertshaw equivalent that meets the spec.
Our Gelco Fireplace Services Process

- 1
Call and schedule. A live person answers. We book a window, text the tech’s name and photo, and send a tracker when they’re en route.
- 2
Camera-scan inspection. NFPA 211 Level 2 standard: camera down the flue, digital photos of the firebox, smoke chamber, damper, and exterior termination. We find the problem before we name a price.
- 3
Written price and scope. Clause 1 of the Haven Standard: written price, written scope, written warranty before any work starts. No exceptions. You sign or you don’t; either way, you keep the inspection photos.
- 4
Parts decision. OEM Gelco when it matters for warranty or fit, quality aftermarket when it performs better or faster. We stock common Gelco blowers, thermopiles, and refractory panels through our Haven buying network with DuraFlex, HeatShield, and other suppliers.
- 5
Repair and test. The work, then a combustion analysis on gas units or a draft test on wood units. We run the appliance through a full cycle while you watch.
- 6
Documentation and cleanup. Clause 4 of the Haven Standard: photo record of completed work, written warranty, and the 365-Day Done Right Promise stamped on the invoice. We leave nothing behind but the fix.

Why Lansdale Homeowners Call Emberly Chimney Cleaners Lansdale for Gelco Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and enough of them were Gelco units that we stock the parts that fail. Corrine Halstead trained in building systems at New York City College of Technology before spending the better part of two decades doing chimney work across Montgomery County. Her crew knows which Gelco serial numbers shipped with the narrow firebox, which DV blowers cross to a better aftermarket spec, and where Lansdale’s clay soil shifts the chimney crown enough to crack the flue liner behind a Gelco insert.
Every job carries the 365-Day Done Right Promise, background-checked uniformed techs with license numbers on the invoice, and Clause 4’s documented photo record. We also service DuraFlex and HeatShield systems, so when a Gelco repair reveals a liner or relining issue, we don’t hand you off. We fix it.
FAQs
No, routine maintenance and repair by an independent qualified technician does not void a Gelco warranty, provided OEM-spec parts are used for any warranty claim. We document parts origin on every invoice for this reason. If your unit is still under factory warranty, we’ll flag that before ordering anything. Call (267) 327-4785 and we’ll check the serial number.
Common items - blowers, thermopiles, refractory panels for current DV and SC series - we stock or source within 2-3 business days through our Haven buying network. Discontinued Gelco lines may take 5-10 days or require a fabricated equivalent. We tell you which before you sign.
Repair if the firebox is sound, the liner is intact, and the repair cost is under half the price of a comparable new insert. Replace if the firebox is cracked through, the liner is compromised, or parts are obsolete and the unit is pre-2005. We camera first, then give you both numbers in writing. No guesswork.
Annually, per NFPA 211, even if it looks fine. Gas fireplaces accumulate dust and debris on burners, blower motors collect lint, and vent terminals clog with Lansdale’s leaf litter and cottonwood seed. The thermopile degrades gradually; you won’t notice until the pilot won’t stay lit on the coldest night of January.
Creosote builds, draft degrades, and the risk of a chimney fire or CO spillage increases. Class I creosote brushes off. Class III creosote, common in Gelco SC units burned with unseasoned hardwood, is a fuel source and a restriction. We camera, classify it, and show you. If it’s safe to wait, we say so. If it’s not, we show you why. Call (267) 327-4785 for a free estimate.
