made for combustion and ventilation air. Consult the
written instructions provided with the heater for
information concerning combustion and ventilation air.
In the absence of instructions, refer to the National Fuel
Gas Code, ANSI Z223.1, Section 5.3 or applicable local
codes.
This heater is equipped with a PILOT LIGHT SAFETY
SYSTEM designed to turn off the heater if not enough fresh
air is available.
DO NOT TAMPER WITH PILOT LIGHT SAFETY
SYSTEM!
If heater shuts off, do not relight until you provide fresh air.
If heater keeps shutting off, have it serviced. Keep burner
and control compartment clean.
12409-2-0403
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, heater may not be working properly. Get fresh air at
once! Have 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.
The pilot light safety system senses the depletion of oxygen
at its location. If this heater is installed in a structure having
a high vertical dimension, the possibility exists that the
oxygen supply at the higher levels will be less than that at
the heater. In this type of application, a fan to circulate the
structure air will minimize this effect. The use of this fan
will also improve the comfort level in the structure. When
a fan is used to circulate air, it should be located so that the
air flow is not directed at the burner.

SAFETY INFORMATION FOR USERS OF LP-GAS
Propane (LP-Gas) is a flammable gas which can cause fires
and explosions. In its natural state, propane is odorless and
colorless. You may not know all the following safety precautions which can protect both you and your family from an
accident. Read them carefully now, then review them point
by point with the members of your household. Someday
when there may not be a minute to lose, everyone's safety will
depend on knowing exactly what to do. If, after reading the
following information, you feel you still need more information, please contact your gas supplier.

firefighters declare them to be safe.
NO ODOR DETECTED - ODOR FADE
Some people cannot smell well. Some people cannot smell the
odor of the chemical put into the gas. You must find out if you
can smell the odorant in propane. Smoking can decrease your
ability to smell. Being around an odor for a time can affect your
sensitivity or ability to detect that odor. Sometimes other odors
in the area mask the gas odor. People may not smell the gas odor
or their minds are on something else. Thinking about smelling a
gas odor can make it easier to smell.
The odorant in LP-gas is colorless, and it can fade under
some circumstances. For example, if there is an underground
leak, the movement of the gas through soil can filter the odorant.
Odorants in LP-Gas also are subject to oxidation. This fading can
occur if there is rust inside the storage tank or in iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into
walls, masonry and other materials and fabrics in a room. That
will take some of the odorant out of the gas, reducing its odor
intensity.
LP-Gas may stratify in a closed area, and the odor intensity could
vary at different levels. Since it is heavier than air, there may be
more odor at lower levels. Always be sensitive to the slightest
gas odor. If you detect any odor, treat it as a serious leak.
Immediately go into action as instructed earlier.
SOME POINTS TO REMEMBER
• Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it to
find out what the propane odor smells like. If you suspect that
your LP-Gas has a weak or abnormal odor, call your LP-Gas
Dealer.
• If you are not qualified, do not light pilot lights, perform
service, or make adjustments to appliances on the LP-Gas
system. If you are qualified, consciously think about the odor
of LP-Gas prior to and while lighting pilot lights or performing service or making adjustments.
• Sometimes a basement or a closed-up house has a musty
smell that can cover up the LP-Gas odor. Do not try to light
pilot lights, perform service, or make adjustments in an area
where the conditions are such that you may not detect the
odor if there has been a leak of LP-Gas.
• Odor fade, due to oxidation by rust or adsorption on walls of
new cylinders and tanks, is possible. Therefore, people
should be particularly alert and careful when new tanks or
cylinders are placed in service. Odor fade can occur in new
tanks, or reinstalled old tanks, if they are filled and allowed
Page 4
to set too long before refilling. Cylinders and tanks which
have been out of service for a time may develop internal rust
which will cause odor fade. If such conditions are suspected
to exist, a periodic sniff test of the gas is advisable. If you
have any question about the gas odor, call your LP-gas
dealer. A periodic sniff test of the LP-gas is a good safety
measure under any condition.
• If, at any time, you do not smell the LP-Gas odorant and you
think you should, assume you have a leak. Then take the same
immediate action recommended above for the occasion when
you do detect the odorized LP-Gas.
• If you experience a complete "gas out," (the container is
under no vapor pressure), turn the tank valve off immediately. If the container valve is left on, the container may draw
in some air through openings such as pilot light orifices. If
this occurs, some new internal rusting could occur. If the
valve is left open, then treat the container as a new tank.
Always be sure your container is under vapor pressure by
turning it off at the container before it goes completely empty
or having it refilled before it is completely empty.

GENERAL INFORMATION
This is an unvented gas-fired heater. It uses air (oxygen) from the
room in which it is installed. Provisions for adequate combustion
and ventilation air must be provided.
Keep room area clear and free from combustible materials, gasoline and other flammable vapors and liquids.
Handle the gas log burner assembly by the grate and legs only.
Do not pick the unit up by the burner.
Gloves are recommended when handling ceramic fiber logs
to prevent skin irritation from loose fibers. Logs are fragile Handle with care.
Unvented gas heaters are a supplemental zone heater. They are
not intended to be a primary heating appliance. Water vapor produced by an unvented heater can create moisture problems in a
home when operated for extended periods of time.
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.
The initial break-in operation should last 2-3 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.

WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combustion. An unvented
room heater produces approximately one (1) ounce (30ml) of
water for every 1,000 BTU's (.3KW's) of gas input per hour.
Unvented room heaters are recommended as supplemental heat (a
room) rather than a primary heat source (an entire house). In most
supplemental heat applications, the water vapor does not create a
problem. In most applications, the water vapor enhances the low
humidity atmosphere experienced during cold weather.
The following steps will help insure that water vapor does not
become a problem.
1. Be sure the heater is sized properly for the application, including ample combustion air and circulation air.
2. If high humidity is experienced, a dehumidifier may be used to
help lower the water vapor content of the air.
3. Do not use an unvented room heater as the primary heat source
Exhaust fans, fireplaces, clothes dryers and fuel burning appliances draw air from the house to operate. You must provide
adequate fresh air for these appliances. This will insure proper
venting of vented fuel-burning appliances.
PROVISIONS FOR ADEQUATE COMBUSTION & VENTILATION AIR
This heater shall not be installed in a confined space unless provisions are provided for adequate combustion and ventilation air.
The National Fuel Gas Code defines a confined space as a space
whose volume is less than 50 cubic feet per 1,000 Btu per hour
(4.8m3 per kw) of the aggregate input rating of all appliances installed in that space and an unconfined space as a space whose
volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8
m3 per kw) of the aggregate input rating of all appliances installed
in that space. Rooms communicating directly with the space in
which the appliances are installed, through openings not furnished
with doors, are considered a part of the unconfined space.
Unusually Tight Construction
The air that leaks around doors and windows may provide enough
fresh air for combustion and ventilation. However, in buildings of
unusually tight construction, you must provide additional fresh
air.
Unusually tight construction is defined as construction
where:
a. Walls and ceilings exposed to the outside atmosphere have
a continuous water vapor retarder with a rating of one perm
or less with openings gasketed or sealed, and
b. Weatherstripping has been added on openable windows
and doors, and
c. Caulking or sealants are applied to areas such as joints
around window and door frames, between sole plates and
floors, between wall-ceiling joints, between wall panels, at
penetrations for plumbing, electrical, and gas lines, and at
other openings.
If your home meets all of the three criteria above, you must
provide additional fresh air.
Warning: If the area in which the heater may be operated is
smaller than that defined as an unconfined space or if the building
is of unusually tight construction, provide adequate combustion
and ventilation air by one of the methods described in the National
Fuel Gas Code, ANSI Z223.1, Section 5.3. or applicable local
codes.
12409-2-0403
Example of Large Room with 1/2 Wall divider.
Figure 1
The following formula can be used to determine the maximum
heater rating per the definition of unconfined space:
Btu/Hr =
(L1 + L2)FT x (W)FT x (H)FT
x 1000
50
If the area in which the heater may be operated is smaller than
that defined as an unconfined space, provide adequate combustion
and ventilation air by one of the methods described in the National
Fuel Gas Code, ANSI Z223.1, Section 5.3.

INSTALLING AS A VENTED APPLIANCE
Manual and millivolt controlled gas logs may be installed as a
vented decorative log set in compliance with ANSI Z21.60 and
National Fuel Gas Code, Section 6.6 since, the gas logs are operated with the damper open, non-combustible material and minimum mantel requirements do not apply.
This appliance is for installation only in a solid fuel burning fireplace (masonry fireplace or manufactured fireplace) with a working flue and constructed of noncombustible material.
Damper stop installation:
A damper stop must be provided with the unit. Contact your dealer
to obtain one. The damper stop must be installed as shown in
(Figure 9) to prevent full closure of the fireplace damper blade
and provide a minimum 29 square inch flue opening.
State of Massachusetts requirement for installation of vented
decorative appliance in a vented fireplace is the following:
A vented decorative gas appliance must be installed in a vented
fireplace only in the state of Massachusetts. The vent damper
must be removed or welded permanently open.
Page 10
Damper Stop Installation
Figure 9
12409-2-0403
BEFORE FULLY INSTALLING THE APPLIANCE
• Turn off the gas supply to the fireplace or firebox.
• Seal any fresh air vents and/or ash clean-out doors located on
the floor or wall of the fireplace. If left unsealed, drafting may
cause pilot outage or sooting. Use a heat resistant sealant. Do
not seal the chimney flue damper.
Before installing in a solid fuel burning fireplace, the chimney
flue and firebox must be cleaned of soot, creosote, ashes and loose
paint by a qualified chimney cleaner.
You must secure the gas log heater to the fireplace floor.
If not, the entire unit may move when you adjust the
controls. Movement of unit may cause shifting of the gas
logs which leads to sooting and improper burning. Grate
movement could cause a gas leak.
Special care is required if you are installing the unit into
a sunken fireplace. You must raise the fireplace floor to
allow access to gas log controls. This will insure adequate
air flow and guard against sooting. Raise the fireplace
floor using noncombustible materials.
Metal shipping plate covering burner marked REMOVE
must be removed from top of burner and discarded.
Burner will not operate if plate is left in place.
Save for future use – when servicing fireplace.
Assembly Procedure: (Figure 10)
1. Center the gas log unit in the fireplace or firebox. Make certain
the front feet of the grate sit inside the front edge of the
fireplace or firebox.
2. An anchor hole is provided in the two bottom side members of
the grate frame. After centering the grate correctly, mark the
hole positions on the fireplace/firebox floor. Drill two (2) 5/
32" diameter holes approximately 1-1/2" deep for masonry
screws or 1/8" hole for sheet metal screws.
3. Anchor the grate to the fireplace/firebox floor using the screws
provided. Refer to Figure10.
Proper installation of the grate is essential to prevent any
movement of the gas logs and controls during operation.

RWO Curing Process
The logs shipped with this product are formed from a cast
refractory material. The curing process for this material won't be
completed until after your new burner assembly has fired for a
period of time. During this curing period you may notice popping
noises and small pieces of material coming from the logset. This
is caused by moisture near the surface of the logs and is normal.
Anytime your vent-free burner is operating, the screen curtains
on the fireplace or firebox should be closed. This is especially true
during the first few hours of operation.
Log Placement
VFYR and VFYM-16SO Logs Shown

PLACEMENT OF GLOWING EMBERS AND LAVA ROCK
Provided with the log set is a small bag of glowing embers (rock
wool) to be placed between logs on the flat metal surface of the
burner.
Placement of the glowing embers (rock wool) is very individual
and light coverage of the areas indicated will provide your best
effects. We recommend separation of the rock wool by hand and
make your coverage as light and fluffy as possible.
Place just enough embers on the burner to obtain the glow and a
gold yellow flame.
Do not place embers (rock wool) over large ports in rear portion
of burner.
A thin layer of glowing embers (rock wool) should be placed
under open space between the right and left middle logs.
Rock wool should not be placed in the area of the pilot assembly.
Placing Lava Rock in Front of Grate and Burner Pan on Fireplace Floor
Spread lava rocks on fireplace floor in front of grate and burner
pan. The lava rocks are for decorative effect and are not required
for fireplace operation.

OPERATION INSTRUCTIONS / FLAME APPEARANCE
Flames from the pilot (rear right back side of the pan burner) as
well as the main flame should be visually checked as the log set
is installed.
This appliance must not be used with glass doors in the closed
position. This can lead to pilot outages and severe sooting outside
the fireplace.
In normal operation at full rate after 10 to 15 minutes, the flame
appearance should be sets of yellow flames.
NOTE: all flames will be random by design, flame height will
go up and down.
Glowing embers (rock wool) can cover the pan burner in between
the front and middle logs, but very little is necessary to cover this
area. Excess ember material causes the yellow flame to become
orange and stringy. Apply just enough to obtain slow glow and a
gold yellow flame.
Manual - Figure 17
Avoid any drafts that alter burner flame patterns. Do not allow
fans to blow directly into fireplace. Do not place a blower inside
the burner area of the firebox. Ceiling fans may create drafts that
alter flame patterns. Sooting and improper burning will result.
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.
The initial break-in operation should last 2-3 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 will be slight and will disappear with
continued use.

PILOT FLAME CHARACTERISTICS
Figures 19 and 22 show a correct pilot flame pattern. The correct
flame will be blue and will extend beyond the thermocouple. The
flame will surround the thermocouple just below the tip. A slight
yellow flame may occur where the pilot flame and main burner
flame meet. Figures 20 and 23 show an incorrect pilot flame
pattern. The incorrect pilot flame is not touching the thermocouple.
This will cause the thermocouple to cool. When the thermocouple
cools, the heater will shut down.

Millivolt Control
The valve regulator controls the burner pressure which should be
checked at the pressure test point. Turn captured screw counter
clockwise 2 or 3 turns and then place tubing to pressure gauge
over test point (Use test point “A” closest to control knob). After
taking pressure reading, be sure and turn captured screw clockwise firmly to re-seal. Do not over torque. Check for gas leaks.
Wiring Diagram (Figure 25)
Label all wires prior to disconnection when servicing controls.
Wiring errors can cause improper and dangerous operation. Verify
proper operation after servicing.
750 Millivolt System
When you ignite the pilot, the thermocouple produces millivolts
(electrical current) which energizes the magnet in the gas valve.
After 30 seconds to 1 minute time period you can release the gas
control knob and the pilot will stay ON. Allow your pilot flame
to operate an additional one (1) to two (2) minutes before you turn
the gas control knob from the PILOT position to the ON position.
This time period allows the millivolts (electrical current) to buildup to a sufficient level allowing the gas control to operate
properly.
16", 18", 24" and 30" Gas Logs (Millivolt) thermopile is self powered gas valve and does not require 110 volts. Refer to (Figure
25) to provide optional wall switch, thermostat, or remote control. Maximum length of 20 feet of 18 AWG to conductor wires is
to be used with all optional switches.
