Will this unit work at high altitude such as 6100 ft? Also, I have a 350 gal propane tank that feeds my furnace with a pipe that I can branch off on. Would I still need to connect another regulator to this or should the one on the big tank suffice?
By eFireplaceStore on May 27, 2014
Answer:Vent free heaters work consistently at altitudes up to 4,500 feet. Between 4,500 and 7,500 feet, oxygen levels drop enough that the oxygen depletion pilot assembly can experience intermittent drop outs. The issue is not common, but it can be a nuisance when it does occur.
Depending on the pressure level that the first regulator steps the output to, you may need a second regulator for this heater. The heater requires an input pressure between 11 and 13 inches of water column, with 13 inches being approximately 1/2 of a psi. If the first regulator steps pressure down to this level, another regulator will not be needed.

I am looking fora wall heater for a 250 sq ft great room and a 100 sq ft bedroom. I like the look of the infrared models and like the fact that no vent is required. What would you recommend?

Why does this Empire gas heater not need a vent? Does that mean it doesn't need to be on an outside wall?
By Brennan W. on March 30, 2015
Answer:This unit does not need to be vented because it operates at a level of efficiency that puts out only water vapor and carbon dioxide during combustion. You would not need to mount this to an exterior wall.

Can I use this unit in my 40' x 10' mobile home? Will there be enough ventilation?
By Collin C. - NFI Master Hearth Professional on May 29, 2013
Answer:Based on the size of the mobile home, ventilation for this size of a heater should not be an issue. However, the heater cannot be the primary heat source for the mobile home. This restriction stands for all vent free appliances. It is recommended that you consult with your local code office as well, as they may have further guidelines regarding vent free heaters.

What is the hydraulic thermostat in this Empire SR18T infrared vent-free gas heater with hydraulic thermostat controls and how does it work?
By eFireplaceStore on November 9, 2015
Answer:A hydraulic thermostat is a type of thermal modulation device used by some gas space heaters. The thermostat works by utilizing a vial of expanding fluid to trip a switch. Adjusting the temperature controls on the unit adjusts the location of the switch contacts. When the fluid in the vial expands enough, due to the increase in room temperature, it will open the contacts on the switch and turn the unit off. Once the room temperature goes back down and the fluid in the vial cools enough, it will contract and allow the switch to close again, causing the heater to fire again.

I would like to mount this within a fireplace where the logs would be. Is that possible?

Answer:You should not install the heater in this application as adequate airspace clearances will not be provided and this may prove to be quite hazardous.
