The right Rasmussen burner depends on your fireplace’s dimensions, the approved log arrangement, and the flame and ember appearance you prefer. If you want remote operation, you also need to select a compatible valve and control system.
This overview compares the F, FX, CS, CXF, TNA, LC, and LD vented burner families. Confirm the exact burner, fuel, log set, and control configuration against Rasmussen’s installation requirements before ordering.
Rasmussen Gas Burner Basics
Valve Vanisher
Rasmussen’s Valve Vanisher conceals the controls beneath a raised burner assembly. On compatible configurations, this reduces the need to shift or downsize the log set to make room for a control box beside it.
The design places heat-sensitive components in a cooler area, but correct installation and airflow still matter. Keep its ventilation openings unobstructed, and use the dimensions specified for the complete Valve Vanisher configuration.
Valve Vanisher describes the control-housing arrangement, not one universal remote system. Check the included valve and ignition type to determine how the burner operates and which controls it accepts.
Included Components
Rasmussen lists pan filler, Ember Magic, a connector kit, a damper clamp, and installation instructions with its vented burner systems. Its standard pan-filler guidance specifies granulated white sand for natural gas and black volcanic ash for propane; specialty configurations may differ.
Check the exact package contents before ordering. Do not assume the logs, grate, valve, receiver, and handheld remote are all included, or that the supplied connector kit covers every installation requirement.
Double-Face Configurations
For a see-through fireplace, choose a burner and log arrangement approved for viewing from both sides. Rasmussen offers dedicated double-face configurations, including the DF-CF. A standard single-face burner is not automatically suitable for a two-sided installation.
A Closer Look at Rasmussen Fireplace Burners
F Burner
The F is a single-tube burner used beneath a log grate. It offers a compact ember bed and is a starting point for a traditional log presentation.
FX Burner
The FX uses the F burner’s main-tube design with two added ember-booster tubes. Consider it when you want a larger, brighter ember bed in front of the logs.
CS Burner
The CS is a pan-style burner that can be installed with legs or without them for a lower, pit-fire appearance. The logs sit on the pan filler inside the burner; this design does not use a separate log grate.
CXF Burner
The CXF combines the CS-style flame presentation with the expanded ember bed associated with the FX. Its ramped pan is height adjustable. Like the CS, it supports the logs within the pan rather than on a separate grate.
TNA Burner
The TNA is designed for narrow-backed Kiva and Rumford fireplaces, with approved tipi-style log arrangements or specified andiron configurations. Compare the complete set’s requirements with your fireplace’s shape and dimensions.
LC and LD Burners
LC and LD systems integrate multiple burner levels with the log grate. Rasmussen lists LC sizes of 18, 24, and 30 inches, while LD models cover larger configurations beginning at 30 inches. Check the selected model’s dimensions and approved log combinations rather than choosing by nominal size alone.
Choose the Controls Separately from the Burner Style
A burner family name describes the burner design, not necessarily its ignition or remote functions. Depending on the configuration, Rasmussen systems may use manual controls, a remote-ready standing pilot, variable-flame controls, or electronic ignition.
- For on/off control: Confirm the valve type and approved transmitter-and-receiver combination.
- For remote flame adjustment: Select a control system designed to provide that function. An on/off remote does not add flame adjustment.
- For automatic pilot lighting: Look for the appropriate electronic ignition configuration. A standing-pilot remote generally controls the main burner rather than lighting the pilot.
For example, Rasmussen identifies its RPK3E remote-ready control as a latching-solenoid system, not a millivolt system. Similar names or the words “remote ready” are not enough to establish compatibility.
Frequently Asked Questions
Can every manual Rasmussen burner system be upgraded to remote control?
No. Upgrade options depend on the installed valve and approved configuration. Rasmussen describes upgrade kits for certain EASY control systems, while its basic SPK1 manual safety pilot control is not remote-upgradable. Identify the control model before buying an upgrade.
What information should I provide when asking about a replacement remote?
Provide the complete burner model, valve or ignition-system model, fuel type, and existing transmitter and receiver model numbers. Include photos of accessible labels if available. A burner-family name such as FX or CXF alone does not identify the correct replacement remote.
Final Thoughts
Start with the burner and log combination that fits your fireplace, then confirm the control functions you want. The F and FX offer grate-based presentations, the CS and CXF use pan-supported logs, the TNA suits specialized fireplace shapes, and the LC and LD integrate multiple burner levels with the grate.
