Make that old Victorian fireplace an enjoyable feature once again with the 17 inch wide Rasmussen Chillbuster CoalFire Burner. This vent free gas coal burner is without a fireplace coal basket, so you can use your own or go without one. Designed to fit small, shallow depth, coal and wood burning fireplaces, the CoalFire will upgrade an old fireplace into supplemental heat and make it usable again without going through expensive relining or reconstruction. The coals are made from refractory materials that have no potentially harmful ceramic fiber. Turn the valve knob to light the main burner for on and off flame controls and some minimal flame height adjustment. You can have this with or without a remote. There is also a thermostat option, where you can upgrade to a more specific temperature control this with a hand held remote.  Or, you can upgrade to a Variable Flame Height Remote, which will give better control to the flame height with the hand-held wireless remote.

This item is the coal BURNER only. Does NOT include decorative gas coal basket or grate.
You can install the CoalFire in a vent-free, vented and in reduced vent installations.

Manufacturer's Warranty


For Residential Single-Family Indoors (Non-Commercial, Non-Multi-Tenant or Non-Hospitality):
Rasmussen warrants against defects in manufacturing and materials:
Two years for logs, burners, grates and safety lighting controls.

For all Outdoors and Commercial, Multi-Tenant and Hospitality:
Six months for logs, burners, grates and safety lighting controls, except 
No warranty on Safety Lighting Controls for Outdoors installations.

For All Vented and Vent-free Sets:

Rasmussen agrees to repair or replace, at our election, any part or component we deem to be covered under warranty. Buyer must notify Rasmussen within thirty days of defect discovery. Unauthorized returns will be refused. Labor costs are not included in warranty. Shipping and handling costs are the responsibility of the Buyer.

Exclusions from warranty for both Vented and Vent-free sets:
- Maximum liability by Rasmussen is the price paid for the product.
- Misuse, neglect, accident, improper installation or use in violation of instructions are not covered by warranty.
- Repair or alterations not made or authorized by Rasmussen voids all warranties.
- Rasmussen is not responsible for components that did not originate from Rasmussen, regardless of retailer representations.
- Freight damage, cracking from thermal shock,
 color changes and corrosion from outdoor installations are beyond Rasmussen's control and are not covered by any warranty.


Cracks in Logs

Mere cracking is not grounds for warranty replacement of a log, as all logs will experience cracking at some time.  The logs are subjected to uneven heating, which relieves itself through cracking.  Such cracks are most evident in smooth faced logs like split face, manzanita and birch.  We reinforce the logs with steel rods to hold together the log (which is much more rigid and effective than other means used by competitors, such as metal shards, mesh, plastic threads or none at all).
