Stove & insert installation: is a credential required in Kentucky?
#stove-installNONE- Credential
- EXPLICIT statutory carve-out — KRS 198B.650(7) verbatim: ''Heating system' does not include fireplaces and free-standing stoves not incorporated into a primary heating system' — so typical wood/pellet stove and insert installs are NOT the licensed 'practice of HVAC contracting' (KRS 198B.650(15)(a)); the Master HVAC Contractor license DOES attach at the edges: add-on wood furnaces incorporated into primary heat, and solid-fuel boilers/outdoor hydronic heaters ('hydronic system' is inside the practice definition, § 198B.650(8)); permits: 815 KAR 7:125 § 2(2)(a) verbatim — 'Permits, inspections, and certificates of occupancy shall not be required for a single-family dwelling unless required by local ordinance' — stove permits exist only where cities/counties opt in by ordinance; CODE TRAP: the current '2018 Kentucky Residential Code' (Third Ed. Aug 2024, reg eff. 12/3/2024) is based on the 2015 IRC; no statewide GC layer (Louisville/Lexington local per rights research); NFI/CSIA voluntary

- Split by fuel: NG-fired heating appliance work = Master HVAC Contractor (business qualifier) + Journeyman HVAC Mechanic (individual) licenses (KRS 198B.650-.689; 815 KAR 8:010) — whether a purely DECORATIVE gas appliance falls inside the HVAC definition is UNVERIFIED; LP appliance/container/equipment install or connection = LP gas business license (KRS 234.120) — Class (e) 'assembling, repairing, installing, or connecting of LP gas containers, regulating equipment, LP gas appliances, or any LP gas utilization equipment' with $500,000 minimum liability insurance — an explicit LP vs NG split; KY plumbing licensure (KRS ch. 318) does not reach fuel gas (reported); statewide building code exists but GC licensing is local only

- Liability minimum
- Split: HVAC contracting = GL >= $500,000 + property damage >= $300,000 (KRS 198B.668, fetched) — proof to HBC BEFORE issuance/renewal, 'no license shall be valid without the insurance', and CARRIERS MUST NOTIFY the department upon cancellation — the strongest carrier-reporting structure in batch 2; also preempts separate local insurance requirements (198B.668(2)); LP gas licenses = minimum liability by class (KRS 234.120, 2020 text fetched): $1M dealer (a) / $500k small-container+install (b), motor-fuel site (c), INSTALLER class (e) / $100k storage (d), COI filed with HBC named certificate holder (815 KAR 30:010); chimney/masonry/GC = NONE (no state credential)

Before anyone goes on your roof
What should you ask a chimney company in Kentucky?
- Is your company a member of the National Chimney Sweep Guild (NCSG)?
- Does the technician coming to my home hold an individual NCSG certification, and which one?
- Does the technician hold a National Fireplace Institute (NFI) certification — and for which fuel: wood, gas, or pellet?
- What other certifications does the technician hold (for example, CSIA), and can I check them on the issuer's own roster?
- What state or local license or registration covers this work here, and what is the number?
- Will you send a certificate of insurance, dated and naming your company, before work starts?
- Which NFPA 211 inspection level — Level 1, 2, or 3 — are you performing, and why that level?
- Will you show me what you found — photos or video of the flue — in writing?
We take no fee from any certification body, guild, or contractor, and are not paid to mention anyone named.
