6. Installation and repair should be done by a qualified service person.
7. To prevent malfunction and/or sooting, an unvented gas heater/firebox
should be cleaned at least annually by a professional service person. More
frequent cleaning may be required due to excessive lint from carpeting, etc.
It is imperative that control compartments, burners and circulating air
passageways be kept clean.
8. CARBON MONOxIDE pOISONING: Early signs of carbon monoxide poisoning are
similar to the flu with headaches, dizziness and/or nausea. If you have these
signs, obtain fresh air immediately. Have the heater serviced as it may not be
operating properly.
9. The installation must conform with local codes or, in the absence of local
codes, with the National Fuel Gas Code, ANSI Z3.l/NFPA54.
10. This unit complies with ANSI Z1.91 ventless firebox enclosures for gas-
fired unvented decorative room heaters.
11. Do not install the unvented heater in a bathroom. 1. Do not install the
unvented heater in a bedroom unless
the maximum input rating is equal to or less than 10,000 Btu/hr.
71D0531
13. Correct installation of the ceramic fiber logs, proper location of the
heater, and annual cleaning are necessary to avoid potential problems with
sooting. Sooting, resulting from improper installation or operation, can
settle on surfaces outside the fireplace. See log placement instructions for
proper installation.
14. Avoid any drafts that alter burner flame patterns. Do not allow fans to
blow directly into fireplace. Do not place a blower inside burn area of
firebox. Ceiling fans may create drafts that alter burner flame patterns.
Sooting and improper burning will occur.
15. CAUTION: Candles, incense, oil lamps, etc. produce combustion byproducts
including soot. Vent-free appliances will not filter or clean soot produced by
these types of products. In addition, the smoke and/or aromatics (scents) may
be reburnt in the vent-free appliance which can produce odors. It is
recommended to minimize the use of candles, incense, etc. while the vent-free
appliance is in operation.
16. An unvented gas-fired heater uses air (oxygen) from the room in which it
is installed. Provisions for adequate combustion and ventilation air must be
provided. See installation guidelines.
17. Keep room area clear and free from combustible materials, gasoline and
other flammable vapors and liquids.
18. Unvented gas heaters are a supplemental zone heater. They are not
intended to be a primary heating appliance.
19. Unvented gas heaters emit moisture into the living area. In most homes of
average construction, this does not pose a problem. In houses of extremely
tight construction, additional mechanical ventilation is recommended.
0. During manufacturing, fabricating and shipping, various components of this
appliance are treated with certain oils, films or bonding agents. These
chemicals are not harmful but may produce annoying smoke and smells as they
are burned off during the initial operation of the appliance; possibly causing
headaches, or eye or lung irritation. This is a normal and temporary
occurrence.
Continued on page 4 3
VF/VFR Vent-Free Fireboxes
Continued from page 3
The initial break-in operation should last two to three hours with the burner
at the highest setting. Provide maximum ventilation by opening windows or
doors to allow odors to dissipate. Any odors remaining after this initial
break-in period will be slight and will disappear with continued use.
1. Input ratings are shown in BTU per hour and are for elevations up to ,000
feet. For elevations above ,000 feet, input ratings should be reduced 4
percent for each 1,000 feet above sea level. Refer to the National Fuel Gas
Code.

A listed manual shutoff valve must be installed upstream of the appliance. A
union tee and plugged 1/8″ NPT pressure tapping point should be installed
upstream of hte appliance.
IMpORTANT: Install main gas valve (equipment shutoff valve) in an accessible
location. The main gas valve is for turning on or shutting off the gas to the
fireplace.
A sediment trap may be upstream of the heater to prevent moisture and
contaminants from passing through trap to the heater controls and burners.
Failure to do so could prevent the heater from operating reliably. Consult
applicable codes.
An external regulator must be used on all propane/L.P.G. heaters, in addition
to the regulator fitted to the heater, to reduce the supply tank pressure to
13″ w.c. (maximum). Any copper tubing used to supply propane / L.P.G. from the
tank must be internally tinned.
NOTE: When connecting propane / L.p.G. vent-free room heaters, you must use
pipe sealant resistant to propane / L.p.G.
IMpORTANT: Hold heater regulator with a wrench to prevent movement when
connecting to inlet piping.
Check gas type: The gas supply must be the same as stated on the heater’s
rating plate. If the gas supply is different, DO NOT INSTALL THE HEATER.
Contact your dealer for the correct model.
Do not connect directly to natural gas 1/2 pSI or 2 pSI systems. Always make
sure natural gas pressure is regulated 10.5 w.c. (maximum before operating the
unit).
After completing connection, test all gas joints from the gas meter to the gas
heater regulator for leaks. Using soap and water solution or a gas sniffer. DO
NOT USE AN OPEN FLAME.
