Can the number of plaques burning of this Empire SR30T infrared vent-free gas heater with hydraulic thermostat controls also be selected?
By eFireplaceStore on November 30, 2015
Answer:This unit is designed so that all 5 ceramic plaques will ignite when the unit is active. There is not a way to make the unit operate with only 1 or 3 plaques burning.

I have bought three items from you before. Two of them work great. However, the vent free unit was not satisfactory as it left a wetness afterward which created mold. I would like to purchase the 30,000 BTU unit in natural gas but am wondering if it will produce a dampness also from burning the natural gas or is it different? I am referring to the SR30T infrared vent free gas heater. Or, do you have a vented unit this size?
By Chris on October 29, 2013
Excess moisture is one of the by products created by vent free appliances. If you were to choose a direct vent model instead of a vent free model, the moisture created would not be an issue as the appliance would be vented to the outdoors. I would suggest the Empire DV35SG Direct Vent Gas Wall Furnace
as a suitable replacement instead of a vent free furnace. In addition to the information above, vent free appliances are not allowed to be installed in Canada as well as several other states and localized municipalities across the United States.

How many square feet does this Empire SR30T infrared vent-free gas heater with hydraulic thermostat contorls heat?
By Will M. on September 22, 2015
Answer:With standard 8' ceilings, this heater will heat approximately 857 square feet.
By Bruce from Waverly, OH on September 22, 2015
Answer:Placed in the center of the home, it will heat a home 60 foot long and 30 foot wide. With the outside temp at zero degrees F and the wind blowing hard. With no wind, it will heat the same home to -15 degrees F. I've owned my first one for 10 years. I'm on my second one now. I was so impressed with the first one that when I bought the second, I also bought a third one for backup.

Does this Empire SR30T infrared vent-free gas heater with hydraulic thermostat controls shut off and on when the desired temperature is reached? Also, does it have a pilot that stays on?
By Will M. on October 5, 2015
Answer:A hydraulic thermostat gives the ability to set the unit at a desired heat range and the unit will cycle at that setting. The temperature swing is usually +/- 2 degrees. The system works by utilizing a vial of expanding fluid. As the fluid expands with room temperature, it trips the control valve and shuts the unit down. When the fluid cools and contracts, it turns the unit on again.
This model will feature a standing pilot equipped with an ODS or Oxygen Depletion Sensor that will shut off the flow of gas to the burner when the oxygen level around the pilot assembly drops to around 19 percent.

What kind of regulator is required for this unit, and do you sell them?
By Collin C. - NFI Master Hearth Professional on November 8, 2012
Answer:This unit will require a regulator that can step pressure down to approximately 1/2 psi at the inlet of the gas valve. Detailed pressure specs are available in the product manual. Depending on the inlet pressure from your gas supply pipe, you may need a regulator that is rated to handle 1 to 2 psi of incoming gas pressure, but this will depend on your installation.
Also, the regulator thread sizes will depend on the size of your incoming gas line. We do offer a limited supply of adjustable regulators, but if a 3/4 or larger line is used you may need to purchase this type from a local plumbing supplier.

We have one of these that we want to convert to natural gas. Is there a kit available to switch it over?
By Collin C. - NFI Master Hearth Professional on September 13, 2012
Answer:Because of the potential danger of converting a vent free heater incorrectly, manufacturers of these products do not produce conversion kits for them. The heater must only be used with the fuel for which it was originally designed.
