About Siemens Combustion Controls

Precision Combustion Control
for Every Burner

Siemens Combustion Controls is the global standard in burner management technology — from the LFL flame safeguard found on boilers worldwide to the LMV5 linkageless burner management system that represents the state of the art in combustion control. Their products protect people, optimize fuel efficiency, and reduce emissions on every type of commercial and industrial burner.

The Siemens combustion platform covers the complete control chain — flame safeguards, burner controllers, flame detectors, gas valve actuators, combustion air actuators, pressure switches, and sensors. Every component is engineered to work together as an integrated system, not a collection of individual parts.

ICA Heating carries the full Siemens combustion controls line and has been commissioning, tuning, and servicing Siemens-equipped boilers across NJ and NY since 1974. When your combustion system needs attention — from a routine safeguard replacement to a complete linkageless retrofit — ICA is the call to make.

Technology & Advantages

Why Linkageless. Why Siemens.
Why It Matters.

The engineering advantages that make Siemens the preferred combustion control platform for mechanical engineers, contractors, and facility managers running commercial and industrial boilers.

Linkageless Control
The LMV5 eliminates mechanical linkages between fuel valves, air dampers, and flue gas dampers. Electronic actuators with 900 repeatable positions replace cams, levers, and jackshafts — delivering precise fuel-air ratio control that doesn't drift over time.
Integrated O2 Trim
Built-in oxygen trim continuously adjusts the air-fuel ratio based on real-time flue gas analysis. The result: optimized combustion efficiency across the entire firing range — not just at the commissioning setpoint.
Independent Safety Processor
The LMV5 flame safeguard runs on an independent processor — physically separated from the combustion control logic. Safety functions cannot be overridden or compromised by control system faults.
VFD Blower Integration
Integrated variable frequency drive control modulates combustion air blower speed to match firing rate. This reduces electrical consumption at low fire, lowers noise, and extends blower motor life.
Multi-Spectrum Flame Detection
QRI infrared and QRA ultraviolet detectors cover every fuel and firing condition. From standard natural gas to heavy oil, low-NOx, and multi-fuel applications — Siemens has the right flame sensing technology.
15-Point Fuel-Air Curve
The LMV5 allows 15 programmable fuel-air ratio points across the firing range — compared to the 3-5 points typical of mechanical linkage systems. More points mean tighter combustion control and lower emissions.

Frequently Asked Questions

Common Questions About
Siemens Combustion Controls

What is the Siemens LMV5 burner management system?
The LMV5 is Siemens' flagship linkageless burner management system. It integrates flame safeguard (on an independent processor), fuel-air ratio control with 15 programmable points, PID load control for temperature or pressure, integrated O2 trim, and VFD blower control — all in a single platform. It controls up to 5 rotary actuators simultaneously with 900 repeatable positions each, replacing mechanical linkages with electronic precision.
What is the difference between the LMV5 and LMV3?
The LMV5 is the full-featured platform supporting up to 5 actuators, 15 fuel-air ratio points, integrated O2 trim, and comprehensive monitoring. The LMV3 is a compact alternative for simpler applications — supporting up to 2 actuators with single or dual-fuel capability and programmable purge timing. Both provide parallel positioning control and VFD integration.
What is a flame safeguard control?
A flame safeguard is a safety device that monitors the burner startup sequence and continuously verifies flame presence during operation. If the flame is lost or fails to establish during startup, the safeguard immediately shuts off fuel flow to prevent dangerous gas accumulation. The Siemens LFL is one of the most widely installed flame safeguards in the world, with UL, FM, and CSA approvals.
When should I use QRI vs QRA flame detectors?
QRI infrared detectors are the standard choice for burners firing natural gas and light oil — they are reliable, cost-effective, and widely used. QRA ultraviolet detectors are needed for heavy oil, low-NOx burners, and complex firing conditions where background infrared radiation could cause false flame signals. Your burner type and fuel determine which detector is appropriate.
Does ICA service and repair Siemens combustion controls?
Yes. ICA Heating provides complete Siemens combustion control services across New Jersey and New York — including system design, installation, commissioning, combustion tuning, O2 trim calibration, annual inspections, and 24/7 emergency troubleshooting. Our technicians carry replacement LFL safeguards, QRI/QRA detectors, and other critical components for fast on-site repairs.
Can ICA upgrade my boiler from mechanical linkage to linkageless controls?
Yes. Retrofitting from mechanical linkage to Siemens LMV5 linkageless control is one of the most impactful upgrades you can make to an existing boiler. Linkageless control eliminates cam and linkage drift, provides tighter fuel-air ratio control across the firing range, integrates O2 trim, and typically improves combustion efficiency by 2-5% — paying for itself in fuel savings within 1-3 years.
