Ventless (Unvented) Gas Heaters from HearthRite


Reliable heating - Intelligent design - Exceptional value

  • 99.9% efficient - ventless heaters do not send any heat up the chimney.
  • Uses no electricity or batteries - works during electric power failures.
  • Easy source of supplemental heat - simpler to install than forced air ducts; easier to maintain than a radiator.
  • Pushbutton piezo spark ignition and standing pilot.
  • Oxygen depletion sensor (O.D.S.) pilot shuts off before oxygen drops below a safe level
  • Factory verified quality control by actual test firing.
  • Three-year limited warranty on parts and labor.
  • Manual or built-in thermostat control - multiple heat settings.
  • Natural gas or liquid petroleum gas [propane] - specify at time of order - cannot be converted.
  • Wall mount included - optional floor stand available.
  • Infrared (radiant plaques that glow bright orange) or blue-flame models available in a range of heating capacities.
Heating capacity is given in maximum nominal BTU per hour of fuel input.

You can also download the brochure for more information on other models that can be special ordered.

Because of high temperatures, any heating appliance should be located out of traffic and away from furniture and draperies.
Children and adults should be alerted to the hazard of high surface temperature and should be kept away to avoid burns or clothing ignition.

These heaters cannot be used to burn oil, wood, coal or paper.
Heaters use oxygen from the room air.  Do not operate heater in a confined space.
When used without adequate combustion and ventilation air, heater may give off carbon monoxide (CO), an odorless, poisonous gas.
These heaters have a pilot light safety system that turns the heater off if not enough fresh air is available.
Do not tamper with this safety system.  If the heater shuts off, do not re-light until you provide fresh air.
If the heater keeps shutting off, have it serviced.  Keep the burner and control compartment clean.

Carbon monoxide poisoning may lead to death.  Early signs of carbon monoxide poisoning resemble the flu, with headache, dizziness and/or nausea.
If you have these signs, the heater may not be working properly.  Get fresh air at once and have the heater serviced.
Some people (pregnant women, persons with heart or lung disease, anemia, those under the influence of alcohol, those at high altitudes) are more affected by carbon monoxide than others.

Combustion of LPG [liquid petroleum gas] (also called propane [C3H8 or CH3-CH2-CH3]) produces approximately 2.5 times more heat per unit volume than natural gas (methane [CH4]).
Therefore, these gases are not interchangeable.
Never use a type of fuel in a heater for which it was not manufactured, nor at a delivery pressure or altitude for which it is not properly regulated.

Installation and repair must be done by a qualified person and must conform to local codes.
Comply with manufacturer's directions and building codes for installation, operation and maintenance.
In the absence of local codes, the installation must conform with American National Standard (National Fuel Gas Code) known as NFPA 54 and ANSI Z223.1 (latest edition) available from the American National Standards Institute, Inc., 11 West 42nd St., New York, NY 10036, or from the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269, USA.

These heaters are design certified in accordance with American National Standards Institute Z21.11.2a by the Canadian Standards Association as Unvented Room Heaters.
