I am looking for a heat source for a well insulated cabin. I would prefer a direct vent furnace. Will we experience any safety issue concerning carbon monoxide with this non-vented unit? I like the look of this unit. I currently have a Longvie direct vent unit that I would like to upgrade to something more efficient. What is the BTU rating of this heater and the 30BF model?

Answer:Both the BF20 and BF30 vent free heaters are some of the most clean burning style of vent free appliance available. Unlike a vent free fireplace, the flames make no contact with decorative media of any kind, leading to nearly perfect combustion and no release of CO into the space. Efficiency of the heaters is nearly 100%. However, vent free heaters are only intended for use as supplemental heaters, as they consume oxygen from the room. If makeup air is not introduced from time to time, the units will shut down.

When the room temperature reaches the thermostat setting of this Empire BF20 Blue Flame gas heater, does the unit shut off automatically? What is the CFM of the fan for this unit?
By Will M. on November 30, 2015
Modulating hydraulic thermostat or thermostatic bulb heaters will have a dial that corresponds to a temperature range and, yes, the heater will shut down when the bulb senses the temperature has been satisfied.
The heater will not arrive with a blower, but the optional Empire SRB-18T Automatic Blower
can be purchased at an additional cost.

I read the one answer concerning altitude limitations. My house is sitting at 5,600 ft above sea level, in the hills of Prescott, AZ. This unit would be installed in a garage workshop and the garage is not sealed from outside air due to the gaps and air infiltration from around two garage doors. I also have a garage service door that I could crack to permit air into the garage area. Would you still not recommend using this Empire BF20 blue flame gas heater at my altitude due to oxygen limitations?
By Brennan W. on November 10, 2015
Answer:Unfortunately, even with the added air intake in your area, we would not advise installing this unit at your altitude.

Is this unit rated for elevations of 6500 ft. above sea level?
By Collin C. - NFI Master Hearth Professional on January 3, 2014
Answer:The ODS pilot assembly for vent free heaters is calibrated to operate normally up to elevations of 4,500 feet. Above that, you may have nuisance pilot outages, as the oxygen depletion system will cause it to shut down. This is an unfortunate byproduct of the lower oxygen levels at higher altitudes.

Does the BF20 have a variable speed blower fan option? Will the BF10 heat a room 22' x 12' with a 10 foot ceiling that slopes to 8 feet? Or should I go with the BF 20?
By Collin C. - NFI Master Hearth Professional on October 4, 2013
Answer:The BF20 does indeed have a blower option. It is an automatic, single speed fan. Both the heater stand and the blower can be seen under the accessory tab on the item page.
The BF10 would be sufficient to heat the space, as long as the room is well insulated and does not have to be heated up from very cold temperatures. If the insulation is poor or greater than 10 degree temperature cycles are expected, the BF20 would be the better choice.

What is the range of the thermostat of this Empire BF20 Blue Flame gas heater? I am looking for a heater that will come on if the main heat fails when I am not home. Can it be set for 50 degrees? I leave the main heat set for 60 degrees when I am away.
By Brennan W. on February 1, 2016
Answer:Per the manufacturer, the heater has 5 settings, with setting one being at 55 degrees Fahrenheit and setting five being at 95 degrees Fahrenheit.
