IMPORTANT SAFETY INFORMATION

14015-6-0907Page 4
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.
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 precau-
tions 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.
• 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 perform-
ing 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
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 un-
der 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.
• Do not operate electric switches, light matches, use your
phone. Do not do anything that could ignite the gas.
• Get everyone out of the building, vehicle, trailer, or area. Do
that IMMEDIATELY.
• Close all gas tank or cylinder supply valves.
• LP-Gas is heavier than air and may settle in low areas such
as basements. When you have reason to suspect a gas leak,
keep out of basements and other low areas. Stay out until
firefighters declare them to be safe.
• Use your neighbor's phone and call a trained LP-Gas service
person and the fire department. Even though you may not
continue to smell gas, do not turn on the gas again. Do not
re-enter the building, vehicle, trailer, or area.
• Finally, let the service man and firefighters check for escaped
gas. Have them air out the area before you return. Properly
trained LP-Gas service people should repair the leak, then
check and relight the gas appliance for you.
SOME POINTS TO REMEMBER
NO ODOR DETECTED - ODOR FADE
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
That's your signal to go into immediate action!

Qualified Installing Agency
Installation and replacement of gas piping, gas utilization equip-
ment or accessories and repair and servicing of equipment shall be
performed only by a qualified agency. The term "qualified agency"
means any individual, firm, corporation or company which either
in person or through a representative is engaged in and is respon-
sible for (a) the installation or replacement of gas piping or (b) the
connection, installation, repair or servicing of equipment, who is
experienced in such work, familiar with all precautions required
and has complied with all the requirements of the authority having
jurisdiction.
State of Massachusetts: The installation must be made by
a licensed plumber or gas fitter in the Commonwealth of
Massachusetts.
The installation and the provisions for combustion and ventilation
air must conform with the National Fuel Gas Code, ANSI Z223.1/
NFPA54* Canadian Installation Code CAN/CGA B149.
*Available from the American National Standards Institute, Inc. 11 West 42nd St.,
New York, N.Y. 10018.
High Altitude Installation
When installing this unit at an elevation above 2000 feet (in the
United States) it may be necessary to decrease the input rating by
changing the existing burner orifice to a smaller size. Generally,
input should be reduced 4 percent for each 1000 feet above sea
level. However, if the heating value of the gas has been reduced,
this general rule may not apply. Check with local gas utility for
proper orifice size identification.
For Canadian high altitude applications, this appliance is suitable for
installation at elevations between 0 feet (0m) and 4,500 (1,370m)
without change.
When installing this unit at an elevation above 4500 feet (1,370m)
(in Canada), check with local authorities.
Consult your local gas utility for assistance in determining the
proper orifice for location.
• Turn off gas supply to fireplace or firebox.
• Have the fireplace floor and chimney professionally cleaned to
remove ashes, soot, creosote or other obstructions.
Have this cleaning performed annually after installation.
• Seal any fresh air vents or ash clean-out doors located on floor
or wall of fireplace. If not, drafting may cause pilot
outage or sooting. Use a heat-resistant sealant. Do not seal
chimney flue damper.
Installing Damper Clamp (Figure 2)
Remove all ashes or other debris from the fireplace. If the fire-
place is equipped with an ash dump be sure to seal the door with
furnace cement or high temperature silicone. Be sure to check the
damper for proper operation and verify that the flue passageway
is open. Attach damper clamp to the vent damper and tighten hold
down bolt.
Place the clamp over the lip of the damper and tighten the hold
down bolt until the clamp is securely attached to the damper. This
will prevent the damper from accidentally closing.
State of Massachusetts requirement for installation of vented
decorative appliance in a vented fireplace is the following:
In the Commonwealth of Massachusetts vent free products are
not approved.
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.
Figure 2
GENERAL INFORMATION (continued)
FIREPLACE PREPARATION

14015-6-0907 Page 7
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.
1. Center the gas log in the fireplace or firebox. The grates must
clear the fireplace or firebox screen.
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.
Proper installation of the grate is essential to prevent any move-
ment of the gas logs and controls during operation.

Check all local codes for requirements, especially for the size and
type of gas supply line required.
Note: Never use plastic pipe. Check to confirm whether your local
codes allow copper tubing or galvanized.
Note: Since some municipalities have additional local codes, it is
always best to consult your local authority and installation code.
Installing a New Main Gas Cock
Each appliance should have its own manual gas cock.
In the state of Massachusetts the gas cock must be a T handle
type.
A manual main gas cock should be located in the vicinity of the
unit. Where none exists, or where its size or location is not ad-
equate, contact your local authorized installer for installation or
relocation.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liquefied petroleum gases. The gas lines must be
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.
Never use an exposed flame to check for leaks. Appliance must
be disconnected from piping at inlet of control valve and pipe
capped or plugged for pressure test. Never pressure test with
appliance connected; control valve will sustain damage!
A gas valve and ground joint union should be installed in the gas
line upstream of the gas control to aid in servicing. It is required
by the National Fuel Gas Code that a drip line be installed near
the gas inlet. This should consist of a vertical length of pipe tee
connected into the gas line that is capped on the bottom in which
condensation and foreign particles may collect.
The use of the following gas connectors is recommended:
— ANS Z21.24 Appliance Connectors of Corrugated Metal Tubing
and Fittings
— ANS Z21.45 Assembled Flexible Appliance Connectors of
Other Than All-Metal Construction
The above connectors may be used if acceptable by the authority
having jurisdiction. The state of Massachusetts requires that a flexible
appliance connector cannot exceed three feet in length.
Figure 4
Pressure Testing of the Gas Supply System
1. To check the inlet pressure to the gas valve, a 1/8" (3.175mm)
N.P.T. plugged tapping, accessible for test gauge connection, must
be placed immediately upstream of the gas supply connection
to the appliance.
2. The appliance and its individual shutoff valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of 1/2
psig (3.5 kPa).
3. The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff valve during any
pressure testing of the gas supply piping system at test pressures
equal to or less than 1/2 psig (3.5 kPa).
Attention! If one of the procedures results in pressures in excess
of 1/2 psig (14" w.c.) (3.5 kPa) on the appliance gas valve, it will
result in a hazardous condition.
Checking Manifold Pressure
VSR Natural gas models will have a manifold pressure of ap-
proximately 3.5" w.c. (.871kPa) at the pressure regulator outlet
with the inlet pressure to the pressure regulator from a minimum
of 4.5" w.c. (1.120kPa) for the purpose of input adjustment to a
maximum of 10.5" w.c. (2.615kPa). VSM Natural gas models will
have a manifold pressure of approximately 4.5" w.c. (1.12kPa) at
the pressure regulator outlet with the inlet pressure to the pressure
regulator from a minimum of 7.0" w.c. (1.74kPa) for the purpose
of input adjustment to a maximum of 10.5" w.c. (2.615kPa). VSR
and VSM Propane gas models will have a manifold pressure ap-
proximately 10.0" w.c. (2.49kPa) at the pressure regulator outlet
with the inlet pressure to the pressure regulator from a minimum
of 11.0" w.c. (2.739kPa) for the purpose of input adjustment to a
maximum of 13.0" w.c. (3.237kPa).
VSM
Note: A test gage connection is located downstream of the gas
appliance pressure regulator for measuring gas pressure. The con-
nection is a 1/8 inch 3mm) N.P.T. plugged tapping.

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.
Rock wool should not be placed in the area of the pilot assem-
bly.
Placing Lava Rock in Front of Burner on Fireplace Floor
Spread lava rocks on fireplace floor in front of the burner pan.
The lava rocks are for decorative effect and are not required for
fireplace operation.
ATTENTION: DO NOT PLACE LAVA ROCKS ON BURN-
ER, LOGS OR ROCK WOOL. THE LAVA ROCKS SHOULD
ONLY BE PLACED ON THE FIREPLACE FLOOR.
Figure 5
Flames from the pilot (right back side of the pan burner) as well
as the main flame should be visually checked as the log set is
installed.
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.
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 Pattern (Figure 9)
Figure 8 shows a correct pilot flame pattern. The correct flame will be blue and will extend beyond the thermocouple/thermopile. The
flame will surround the thermocouple/thermopile just below the tip. A slight yellow flame may occur where the pilot flame and main
burner flame meet.
After use, cleaning of the pilot burner may be required for the proper flame. The pilot orifice can be cleaned with high pressure air or
by placing under running water. Pilot orifice must be dry before replacement. Use a pipe cleaner to clean inside the pilot after the pilot
orifice has been removed.
To Remove Pilot Orifice
1. Disconnect the pilot supply line at the pilot burner.
2. Remove pilot orifice from pilot burner. It may be necessary to tap on pilot burner in order to remove the pilot orifice.
Pilot Flame Pattern
Figure 9
If pilot flame pattern is incorrect
• See Troubleshooting, page 15
Main Burner Flame Pattern
The main burner flame will be completely yellow.
Main Burner Flame Ignition and Extinction
When the main burner is ignited it will take a few seconds for the full flame pattern to develop.
When the main burner is extinguished it will take a few seconds for the flames to disappear. It is normal to have the flames burn down
near the rock wool, as the remaining gas is burned.
PILOT AND MAIN BURNER FLAME CHARACTERISTICS

14015-6-0907 Page 13
Thermostats are not approved on vented decorated
appliances.
Label all wires prior to disconnection when servicing controls.
Wiring errors can cause improper and dangerous operation. Verify
proper operation after servicing.
VSR gas valve does not require 24 or 110 volts. See Figure 10 to
provide optional wall switch or remote control.
It is important to use wire of a gauge proper for the length of the
wire:
RECOMMENDED WIRE GAUGES
Maximum Length Wire Gauge
1' to 10' 18
10' to 25' 16
25' to 35' 14
Use the two leads (black wires) from ON/OFF switch to attach
optional components.
Check System Operation
Millivolt system and all individual components may be checked
with a millivolt meter 0-1000 MV range.
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.
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.
Remote Receiver -VSR-(18, 24, 30)
Use the following steps to place the remote receiver adjacent to
the gas valve.
Attention:
1. The remote receiver can not be placed behind the gas valve
and burner assembly.
2. When facing the appliance, the remote receiver must be placed
in the right side firebox, toward the front.
Note: Do not let remote control receiver come in contact with
burner assembly.
Refer to remote control installation and operating instructions for
more details on remote control.
VSR Wiring Diagram (Figure 10)
Figure 10
VSR
Note: (Wiring harness located in envelope)
Connect the 2 - 1/4" terminals onto the TH and TH/TP terminals
on valve. Place decorative log to right of the gas valve and burner
assembly. When connecting to remote receiver, cut off 1/4" terminals
from wires attached to ON/OFF switch. Strip wires back about
1/4". Connect stripped ends into remote receiver.
Keep the control compartment, logs and burner area surrounding
the logs clean.
THE LOGS CAN GET VERY HOT— HANDLE ONLY
WHEN COOL.
Always keep the appliance area clear and free from combustible
materials, gasoline, and other flammable vapors and liquids.
Never obstruct the flow of combustion and ventilation air. Keep the
front of the appliance clear of all obstacles and materials.
Inspecting Venting System
A vented fireplace venting system is designed and constructed
to develop a positive flow adequate to remove flue gases to the
outside atmosphere.
Any foreign objects in the venting system, may cause spillage of
the flue gases into the room.
Periodic examination and/or cleaning of the venting system of the
solid-fuel burning fireplace must be done by a qualified service
person. Visually inspect the damper and flue area for excessive
soot build-up. This soot (carbon) may be removed by brushing
with a soft bristle brush.

CLEANING AND SERVICING

14015-6-0907Page 14
SYMPTOMS-POSSIBLE CAUSES AND CORRECTIONS
1. Match will not light pilot.
a. Main shut-off valve closed.
• Make sure that the shut-off valve located on the pipe
supplying gas to the fireplace is open.
b. Air in the gas line.
• Light a match, turn valve knob to "PILOT" position and
depress, keep match near pilot burner until it lights.
c. Valve knob in "OFF" position.
• Turn valve knob to "PILOT" position and depress, keep
match near pilot burner until it lights.
d. Pilot orifice plugged up, not allowing gas to flow.
• This repair requires tools and some degree of experience.
Ask serviceman for assistance.
e. No gas supply to the fireplace.
• Check plumbing to see if gas fireplace has been hooked
up to the gas supply line.
• Propane tanks is empty.
2. Pilot will not stay lit after carefully following lighting instruc-
tions for VSR—Models.
a. Defective pilot generator (thermopile), remote wall
switch.
• Check pilot flame. Must impinge on thermopile. Clean
and or adjust pilot for maximum flame impingement on
thermopile.
• Be sure wire connections from thermopile at gas valve
terminals are tight and thermopile is fully inserted into
pilot bracket.
• One of the wall switch wires may be grounded. Remove
wall switch wires from valve terminals if pilot now stays
lit, trace wall switch wiring for ground. May be grounded
to appliance or gas supply.
• Check thermopile with millivolt meter. Take reading at
thermopile terminals of gas valve. Should read 325 mil-
livolts minimum while holding valve knob depressed
in pilot position and wall switch "Off." Replace faulty
thermopile if reading is below specified minimum.
b. Defective automatic valve operator — Turn valve knob to
"On." Place wall switch to "On" millivolt meter should read
greater than 100 M.V. If the reading is okay and the burner
does not come on, replace the gas valve.
c. Defective thermopile.
• Check all connections and try.
• If still not operating, disconnect lead between thermo-
couple switch and valve operator. Then disconnect lead
to pilot magnet and connect to valve operator terminal
(TP, TH). If pilot remains lit fault lies with thermocouple.
Check that bulb is in proper location. If still not work-
ing replace thermocouple (see drawing in manual for
additional information).
3. Pilot burning, no gas to burner, valve knob "On," wall
switch "On."
a. Wall switch or wires defective.
• Check wall switch and wires for proper connections.
Jumper wire cross terminals at wall switch, if burner
comes on, replace defective wall switch. If okay, jumper
wires cross wall switch wires at valve, if burner comes
on, wires are faulty or connections are bad.
b. Thermopile may not be generating sufficient millivoltage.
• Replace.
c. Plugged burner orifice.
• Check burner orifice for debris and remove.
4. Pilot will not stay lit after carefully following lighting in-
structions for VSM—Models.
a. Defective thermocouple.
• Check that pilot flame impinges on thermocouple. Clean
and/or adjust pilot for maximum flame impingement.
• Ensure that the thermocouple connection at the gas valve
is fully inserted and tight (hand tight plus 1/4 turn) faulty
thermopile if reading is below specified minimum.
• Disconnect the thermocouple from the valve, place one
millivolt meter lead wire on the tip of the thermocouple
and the other meter lead wire on the thermocouple
copper lead. Start the pilot and hold the valve knob in.
If the millivolt reading is less than 15 mv, replace the
thermocouple.
b. Defective valve.
• If thermocouple is producing more than 15 millivolts,
replace faulty valve.
5. Frequent pilot outage problem.
a. Pilot flame may be too low or blowing (high) causing the
pilot to drop out.
• Clean and/or adjust flame for maximum flame impinge-
ment on thermopile or thermocouple.
6. Main burner flame is too low or too high.
a. Check inlet supply pressure for "M" and "R" models.
b. Check manifold pressure on gas valve for "R" models and
inlet regulator on "M" models.

a. To check the inlet pressure to the gas valve, a 1/8" (3mm)
N.P.T. plugged tapping, accessible for test gauge connection,
must be placed immediately upstream of the gas supply
connection to the appliance.
b.The appliance and its individual shutoff valve must be dis-
connected from the gas supply piping system during any
pressure testing of that system at test pressures in excess
of 1/2 psig (3.5 kPa).
c. The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig (3.5 kPa).
Attention! If one of the above procedures results in pressures
in excess of 1/2 psig (14" w.c.) (3.5 kPa) on the appliance
gas valve, it will result in a hazardous condition.
