    Are Vent-Free gas products safe to use in the home?
    Yes. There is a national safety standard for vent-free gas appliances, ANSI Z21.11.2-2002 and the ANSI Z21.11.2a-2003 addenda, and all of ProCom’s heaters are certified to meet these standards.
    How can a consumer be sure of this?
    Look for the CSA symbol on product packaging. This is a certification mark from an accredited safety certification-testing agency (Canadian Standards Association—which covers both the United States and Canada).

    Is it safer to use a vented model instead of a vent-free one?
    Both vented and vent-free gas products are safe, provided they have been certified and they are installed and operated in accordance with ProCom’s instructions.
    What else should a customer know about vent-free gas product usage and care in their home?
    As with all gas appliances, the customer should read and follow the instructions and safety warnings provided on the unit and within the owner’s manual. The area in which the appliance is installed should always be kept clear and free of combustible materials, gasoline and other flammable vapors and liquids. Vent-free gas heaters must be installed be a qualified gas installer and local codes should be checked to ensure proper installation. Also, yearly cleaning, maintenance and professional inspection by a certified gas technician is required.
    Can a vent-free gas heater be used as a sole source of heat?
    All major building codes categorize vent-free products for supplemental use and recommend that a primary source of heat (for example, a furnace) be present in the home before a vent-free product is installed. Operating instructions clearly state they are to be used as supplemental heating only.
    Are vent-free gas products widely accepted for use in the United States?
    Currently, most states in the U.S. allow for the sale and installation of vent-free supplemental gas heat appliances. Local codes may vary. Note that Massachusetts requires Board of State Examiners of Plumbers approval before installation. ProCom’s approval code is G1-1104-48. Also, California does not currently permit the use of vent-free gas heaters.
    Do vent-free gas heaters take all of the oxygen out of the room?
    All products which burn gas and draw combustion air from the living space “take oxygen” from that space. This includes gas cooking ranges which are vent-free units. The owner’s manual on our products and any local code official will inform about the need for make-up combustion air. A typical well-insulated home still has sufficient air movement to completely exchange indoor air for fresh outdoor air several times per hour. If this air exchange did not take place, normal human breathing would eventually take all the oxygen from that space. This normal air exchange provides more than enough make-up air for the vent-free heater. Vent-free heaters have an ODS or Oxygen Depletion Sensor which automatically shuts off the gas supply in the rare event that the oxygen level in the room falls to 18%. This is well above unsafe levels as established by ANSI (American National Standards Institute).
    Besides the ODS valve, what other safety features do vent-free heaters have?
    These heaters have precision-engineered burners to produce the cleanest, most complete gas burn, with no lift-off or flashback when subjected to low input rates, low pressure, or drafts. All units also feature an internal, non-adjustable pressure regulator that prevents over-firing in case of increased gas pressure. Most of our products include an ignition device, usually a Piezo igniter, which eliminates the need for matches. All of our heaters have defined cabinet temperature limits for wall or floor-mounted heaters. Lastly, but the most simple, all of our products feature either safety grills for heaters, or fire screens and hoods on our fireplaces.
    Can I use my existing chimney?
    ProCom Vent-Free Log Sets are certified to be used with the chimney damper open or closed. The chimney should be inspected and cleared for operation by your installer if used to vent combustion products. It is generally better for the appliance if the chimney has a liner installed. Please consult your dealer or installer for definitive information.
    Is it possible for me to convert the gas type on my heater?
    Vent-free heaters cannot be changed from one gas type to another. The Canadian Standards Association has certified each individual heater according to the type of gas being used. Converting the gas type will change the certification and void any warranty on the heater.
    Does the unit produce any moisture?
    Any vent-free unit no matter what the gas type produces water between one half to one pint of moisture per hour, in the room. Under normal household conditions, this will not pose a problem. In the event you are experiencing a problem, you will need to provide an outlet for the moisture. This can be done by using a dehumidifier or providing additional ventilation.
    Can ceiling fans be installed in rooms with vent-free fireplaces?
    Ceiling fans (or oscillating fans) may be used to help distribute the heat; however, fans should not blow directly into the fireplace or create drafts that alter the burner’s flame patterns, which can result in sooting.
    Are you experiencing pilot outage?
    1. Obstruction in the pilot inlet hole- please clean pilot burner with air compressor
    2. Low gas pressure-check incoming gas pressure
    3. High elevation  (4500 feet above sea level)
    4. Using the wrong gas-make sure you are using the type of gas indicated on rating plates
    5. Not enough air or ventilation-provide enough ventilation
    6. A draft blowing out the pilot flame-eliminate draft
    Can’t get a spark from igniter?
    1. Battery may not be installed in igniter-install AAA battery in igniter
    2. Wire may be loose from igniter case-check igniter wire
    3. Battery may be weak-replace battery
    No gas to pilot?
    1. Stuck internal regulator-unstuck plunger located inside of the internal regulator
    2. Small gas line size-increase gas line size to size indicated in the owner’s manual
    3. Low gas pressure-increase gas pressure to proper water column (W.C.) pressure as indicated in the owner’s manual
    4. Low pressure external regulator-replace with high pressure two stage regulator (LP only)
    5. Control knob may not be fully pressed in-make sure knob is on pilot position and fully pressed
    6. Air in gas lines-purge air out of gas lines
    What do I do when I have a missing or damage part?
    Please contact customer service at 877-886-5989
    Why do I smell slight smoke or odor during initial operation?
    1. Residues from manufacturing processes-please, burn the unit on HIGH for 4-6 hours with the windows open to burn off the “New” and the smell should go away
    2. Not enough air-check burner for dirt or debris if found clean burner
    3. Gas regulator defective-replace regulator
    Do I need an external regulator?
    If you are using propane gas, you will need a high pressure dual stage external regulator
    If you are using natural gas and you have a gas meter than you do not need an external regulator
    How much gas pressure do I need?
    If you are using propane gas, you will need between 11’to 14’ of W.C. pressure
    If you are using natural gas, you will need between 5’ to 10.5’ of W.C. pressure
    What is the single AAA battery for?
    The AAA battery is to be placed inside the igniter positive side out
    Do I need to have my heater professionally installed?
    Your heater must be installed by a license gas installer.
    Warranty will be voided in case of self-installation
    How often do I need to maintain/clean my heater?
    Your heater needs to be clean every 3 months or after 2500hrs of operation-read cleaning and maintenance section in the owner’s manual.
    Do I need a vent?
    Our vent-free appliances are 100% vent-free; no vent is needed for operation.

    Our vented gas log sets do require venting. If you are installing your vented gas log set in your existing fireplace it is recommended that you operate the appliance with the flue open at all times.
    Can I purchase direct?
    ProCom does not sell to the general consumer; please contact one of our distributors for purchase
    Can I use LP gas on a natural gas heater or vice-versa?
    If it is a Dual-Fuel heater you may use either gas type.
    If the unit is a dedicated fuel type heater you must use the type of gas indicated on the rating plate, you cannot use liquid propane gas in a natural gas heater or vice-versa
    Can I convert my heater?
    Field conversion is not permitted.
    Is it required to move the sensing bulb?

    2011 Recovery Act Tax Credit Information
    The American Recovery and Reinvestment Act of 2009 (Recovery Act) awarded a 30% consumer tax credit (up to $1,500) for products that met the IRS guidelines. This applied to products purchased in 2009 and 2010. Unfortunately, even though ProCom products are 99.9% energy efficient the IRS did not recognize vent-free heating appliances under the Recovery Act.
