Cremation Furnace Maintenance
Best Practices for Safety, Longevity, and Efficiency
Routine cremation furnace maintenance is essential to the safe and cost-effective operation of your crematory. Whether you operate a small family-owned funeral home or manage a high-volume facility, staying ahead of wear and tear ensures reliable performance, compliance with emissions standards, and peace of mind for your staff and clients.
At Cremation Systems, a division of Armil CFS, we bring over five decades of high-temperature process expertise into every maintenance recommendation. Our best-in-class cremation reports, like the CFS 2300 and CFS 3000, are designed for ease of use and long service life, but even the most advanced systems require regular upkeep.
Why Cremation Furnace Maintenance Matters
Neglected maintenance doesn’t just increase the risk of mechanical failure, it also drives up fuel consumption, accelerates wear on components, and may trigger unexpected shutdowns or emissions compliance issues. Proper service protocols:
- Reduce total cost of ownership
- Extend the lifespan of your retort
- Minimize emissions and environmental impact
- Improve safety for operators and facility staff
- Ensure faster turnaround times for families and clients
By following a consistent maintenance schedule and leveraging the built-in advantages of Cremation Systems technology, you can optimize operations and prevent costly disruptions.
Key Areas of Crematory Service & Maintenance
Our experts recommend a proactive approach centered on four core areas:
1. Routine Inspections
Performing regular visual and operational checks is your first line of defense. We recommend:
- Weekly inspections of refractories, burners, blowers, and control panels
- Checking door seals and insulation for heat leakage
- Monitoring flue stack conditions for buildup or corrosion
- Verifying alarm and safety shutdown functions
Even minor inconsistencies can signal underlying wear or inefficient combustion. Early detection is crucial.
2. Hearth System Upkeep
The hearth tile system bears the brunt of daily operation. Our patented Quick Change Modular Hearth Tile System™ makes replacement fast, clean, and cost-effective.
Instead of a full refractory overhaul, our modular tiles allow:
- Partial replacements without complete teardown
- Minimized downtime during service
- Lower long-term repair costs
If your hearth is showing signs of cracking, excessive ash buildup, or uneven combustion, it’s time to consider a replacement cycle using our quick-swap technology.

3. Combustion System Checks
EPA regulations and local air quality standards demand attention to exhaust and emissions systems. Maintenance should include:
- Regular inspection and cleaning of ignition and opacity monitor components
- Inspection of afterburner and stack temperatures
- Ensuring proper airflow and draft levels
- Tuning of air-to-fuel ratios for optimal burn
Our CFS-series retorts are designed to help you stay in compliance, but routine maintenance is essential to ensure they perform as intended.
4. Remote Monitoring & Diagnostics
Cremation Systems units are equipped with Tek Marshal™— our remote diagnostics and monitoring technology. This cloud-based system enables:
- 24/7 equipment status tracking
- Real-time alerts for fault conditions
- Remote support from our service team
- Reduced need for on-site service calls
With Tek Marshal™, you’re never operating blind. Our techs can remotely troubleshoot most issues before a service visit is required, saving time, cost, and stress.

Signs Your Crematory System Needs Service
You don’t have to wait for a breakdown to act. Watch for:
- Uneven burns or extended cycle times
- Higher-than-normal fuel usage
- Persistent odors or visible smoke
- Control panel warnings or alerts
- Delayed chamber cooldowns
Early service intervention often prevents expensive part replacements and delays that affect clients.

FAQ: Cremation Furnace Maintenance
How often should a cremation retort be serviced?
We recommend a comprehensive inspection and tune-up every 6–12 months, depending on volume. NFPA 86 – 2015 Section 7.4 requires annual inspection. High-use units may require quarterly checks.
What’s the average lifespan of a cremation furnace?
With proper maintenance, a high-quality system like the CFS 2300 can operate efficiently for over 20 years.
Can I replace just part of the hearth tile system?
Yes. Our Quick Change Modular Hearth System enables section-by-section replacement without requiring extended shutdowns for repairs.
How does Tek Marshal help reduce service costs?
Tek Marshal’s remote access feature enables our technicians to identify and often resolve issues without requiring a site visit, thereby cutting costs and delays.
