Locating the Heater
WARNING: Gas burning appliances require air for combustion and proper venting. Minimum fresh air opening of 1 square inch per 1,000 BTU per
hour input rating must be provided for ventilation. EXAMPLE: A 30,000 BTU per hour input unit requires the equivalent of a 30 inch wide window be
open 1 inch for safe operation.
A. In choosing the location for the heater, the following factors should be considered:
1. Convenience to gas supply.
2. Arrangement of rooms or area to be heated.
3. Probable location of furniture.
4. General appearance.
5. Safe clearance from anything that could catch fire.
6. Ability to properly vent the heater.
B. Locate the heater centrally in the area which it is to heat. The ideal location is at the
source of cold air, which is an outside wall. If the heater is on an outside wall, the cold
air will be warmed before it moves through the room.
C. Place the heater where the air will circulate freely throughout the area to be heated. If one heater is intended to heat the entire house, it is
advisable to consider the installation of grilles immediately below the ceilings to permit circulation of hot air from room to room. Return air grilles
are also desirable.
D. Be certain the heater is placed where the air is free to circulate around it. Never install the heater in a wall recess. The minimum clearance
required to any wall or object can be found on the rating plate located inside the furnace control door on the base plate. We recommend a 24-inch
min. clearance from the burner access door for the ease of lighting and for observation of pilot and burner flames.
E. Heater must be installed so that the drafthood is in the same pressure zone as the combustion air.

For natural gas, the minimum inlet gas supply pressure for the purpose of input
adjustment is 5” water column. The maximum inlet gas supply pressure is 7”
water column.
For L.P. gas, the minimum inlet gas supply pressure for the purpose of input
adjustment is 11” water column. The maximum inlet gas supply pressure is 13”
water column.
Gas pressures and input to the burners must not exceed the rated input and
pressure shown on the rating plate. On natural gas the manifold pressure
shown should be 4” water column. The manifold pressure should be 10.5” water
column for L.P. gas.
Orifice changes may be required to suit gas supplied.
For heaters located at elevations between sea level and 4,500 feet, the
measured input must not be greater than the input shown on the rating plate of
the heater. For elevations above 4,500 feet, the measured input must not
exceed the input of the rating plate reduced by 4 percent for each 1,000 feet
that the heater is above sea level.
Minimum Fresh Air Opening is 1 Square Inch Per 1,000 Btu/Hr
WARNING
Danger of property damage, bodily injury
or death. Even when a house meets
requirements for unconfined space with
adequate air infiltration, it is
recommended that a fresh air intake be
installed to lessen the possible dangers
from any future changes on the home.

Thermostat Installation
Williams’ heaters are operated by a millivolt type thermostat. Current
to the thermostat is supplied by the pilot generator. Do not connect to
electricity. Anticipator settings are not required.
1. Use of existing wire is acceptable if it is in a satisfactory location
and the wire is in good condition. When in doubt, use new wiring.
2. If a new location is chosen or if this is a new installation, thermostat
cable must first be run to the location selected. All wiring must
agree with local codes and ordinances. These instructions cover
bringing the wire down from the attic but it can be run from a
basement or crawl space using similar methods.
3. Before drilling a hole in wall at selected location, drive a small
finishing nail through the ceiling in the corner of the wall and ceiling
above the thermostat location. Pull the nail out and push a small
stiff wire through the hole so it can be found in the attic. Drill a 1/2-
inch hole through the ceiling wall plate.
4. Probe for obstructions in the partition. Then, drill a 1/2-inch hole
through wall at selected location for thermostat.
5. From the attic, feed the thermostat wire through wall until even with
thermostat location.
6. Snag thermostat wire through hole and pull wire through hole in
wall so that 6-inches of the wire protrudes.
7. Route wire to heater.
Wall-Mounted Thermostat Installation
1. To remove thermostat cover, squeeze both sides and lift.
2. Connect thermostat wires to the thermal screws on the back
of thermostat base.
3. Push any excess wire back through hole in wall and plug
hole with insulation to prevent drafts from affecting thermostat
operation.
4. Be sure to level thermostat for best appearance. Fasten
thermostat base to wall through mounting holes with screws
provided.
5. Replace the thermostat cover.
6. Do not run wire in any location where it might be damaged. Avoid
splicing thermostat wires unless the spliced wires are properly
cleaned, soldered and taped.

This heater must be properly connected to a venting system. This heater is equipped with a vent safety shutoff system to protect against improper
venting of its’ combustion products. Tampering with or removal of this control will void the limited warranty and can result in carbon monoxide (CO)
poisoning and possible death.
WARNING: Operation of this heater, when not connected to a properly installed and maintained venting system or tampering with the vent safety
shutoff system, can result in carbon monoxide (CO) poisoning and possible death.
This appliance needs fresh air for safe operation and must be installed so there are provisions for adequate combustion and ventilation air. This room
heater is equipped with a vent safety switch. The vent safety switch will cause gas flow to the main burner to shutoff due to improper venting or a
blocked flue. If the vent safety switch continues to shutoff the gas flow, a qualified service person must be contacted to inspect for improper venting,
blockage in the vent pipe or the vent safety switch for being defective.
WARNING: Do not bypass the vent safety shutoff switch. To do so could expose the
consumer to property damage, personal injury or possible death.
A. An effective flue is necessary to carry off water vapor, carbon monoxide (CO), carbon
dioxide (CO2), and other products of combustion. For proper venting, follow
the following basic rules for gravity venting, which are:
1. Keep the flue gasses hot.
2. Follow the vent manufacturer’s installation instructions.
3. Select the proper vent size.
4. Provide constant fresh air replacement.
B. For new installation, it is recommended that a Type “B” vent in accordance with its’ listing be used. A Type “B” vent is one made of non
combustible, corrosion resistant material of sufficient thickness, cross sectional area and heat insulating quality to avoid excess temperatures on
adjacent combustible material and certified by a nationally recognized testing agency. Existing brick flues should be lined to provide an effective vent.
Brick chimneys, even in good repair, may be too large and will not provide sufficient draft to effectively vent a heater.
C. Use vent pipe of the same size as the outlet on back of heater. In no case should a different size vent be used. Single wall vent pipe may be
attached directly to the drafthood of the room heater when a clearance of 2-1/2 inches (64mm) is maintained between the single wall vent pipe and
the combustible wall of the room in which the room heater is located. Use double wall vent pipe for clearances less than 2-1/2 inches (64mm) to
combustibles.
D. Avoid a horizontal run to vent pipe whenever possible. When a horizontal run is necessary, the pipe must pitch upward at least 1/4 inch to the foot.
It must be supported securely and joints fastened by sheet metal screws or rivets. Under no circumstances should the vent run downhill.
E. Never put a damper or barometric draft control in a gas vent pipe.
F. Never end a vent in an open attic or run vent through a wall to the outside without extending it
upward above the roof.
G. Always terminate vent with an approved cowl.
H. ALWAYS SECURE VENT PIPE TO OUTLET ON BACK OF HEATER WITH A SHEET METAL SCREW.
I. Flue pipe should extend through the wall of a chimney to be flush with inner wall.
J. Flue pipe must be adequately supported by metal strips.
K. For flue pipe running through walls and roofs, use B-1 (1 inch (25mm) clearance to combustibles) vent pipe.
L. Chimneys should extend at least 2 feet (.6m) above the roof and above any object or nearby building within 10 feet (3m).
M. Open tees should not be used in the flue pipe.
N. Heater must not be connected to a chimney flue that is servicing a separate solid-fuel burning appliance.
O. For proper venting, do not attach a 90 degree elbow directly to draft diverter. It is recommended to attach 2 feet (.6m) of straight vent pipe before
an elbow is used. Use 45 degree elbows if possible. Run flue pipe as direct as possible with a minimum of elbows.
P. The use of more than one appliance per vent system may cause the vent safety shutoff device to shut off the heater due to the cooling of vent
temperatures through the draft diverter of the second appliance.
Q. The vent safety shutoff may shut down the heater if a too large or an unlined, masonry chimney is used. The vent may not warm quickly enough
to get adequate vent action in a chimney before the shutoff device will shut down the heater. If this is the case, it is recommended lining the chimney
with proper size type “B” vent pipe or type “B” chimney liner.
R. Single-wall metal pipe should not be used outdoors in cold climates or venting gas equipment. If the vent is installed directly outside, the cold pipe
may delay the venting and cause the heater to shut-off by the vent safety switch. To prevent this problem, as well as condensation of flue products,
an insulated enclosure is recommended. Use type B, vent pipe and maintain at least a one inch clearance to combustibles. Use a metal thimble to
protect vent pipe as it passes through combustibles.
IMPORTANT: Inspect venting system prior to each heating season.
Warning
Danger of illness, bodily injury or death. This
heater and any other fuel burning appliance
must be provided with enough fresh air for
proper combustion and ventilation of flue
gasses. Most homes will require that outside
air be supplied into the heater area.

Warning
Danger of property damage, bodily
injury or loss of life. Do not install
heater in any area where oxygen
is in use.

Typical Methods of Safely Venting Your Heater
1. Any horizontal run of vent pipe must slope upward a minimum of 1/4” per foot.
Secure all joints of the vent with sheet metal screws.
2. Where the vent passes through the ceiling or wall, a thimble is required to keep
the ceiling from catching fire. Use only a thimble designed for use with Type “B” gas
vent, certified by a nationally recognized testing agency.
3. The vertical (straight up and down) part of the vent must end 2 feet above any
part of the roof within 10 feet of the vent. This is to make sure the “draw” of the vent
is not obstructed in any way.
4. A cowl or cap, approved by a nationally recognized testing agency, must be
installed on top of the vent to keep out rain and snow and to prevent obstructions of
the vent. The cowl will also prevent excessive downdraft that can cause carbon
monoxide to enter into the home. Do not use a homemade cowl. They are
dangerous and can restrict the draft of the vent.
5. Safe clearances are shown below. To prevent a fire, make sure the heater is
installed no closer than the distances shown in the figures that apply to your type of
venting.
6. If you are venting into a masonry chimney, it must be lined, in good repair and
must not serve a wood or coal burning appliance. The flue must be at least as large
in diameter as the vent connector. The top of the chimney must be two (2) feet
higher above any part of the roof within ten (10) feet horizontally of the chimney and
must be three (3) feet higher than the point where it passes through the roof line. If
installed in front of a fireplace, the pipe must pass through a sheet metal cover on
the fireplace that fits tightly.

Start-Up Procedure
Check the heater operation as outlined in the following instructions. If
any sparking, odors or unusual noises are encountered, shut off electric
power immediately. Recheck for wiring errors, or obstructions in or
near fan motor (if equipped).
Check Gas Input and Pressures
For heaters located at elevations between sea level and 4,500 feet, the
measured input must not be greater than the input shown on the rating
plate of the furnace. For elevations above 4,500 feet, the measured
input must not exceed the input of the rating plate reduced by 4 percent
for each 1,000 feet that the heater is above sea level.
Gas supply pressure and manifold pressure with the burner operating
must also be as specified on the rating plate.
Rated input will be obtained on the heating valve of 2510 Btu/hr for
propane at 10.5-inches manifold pressure and factory-sized orifices. If
L.P. Gas having a different heating value is supplied, orifices must be
changed by a qualified service technician before the heater is operated.
Check the Manifold Gas Pressure
A tapped opening is provided in the gas valve to facilitate measuring the
manifold gas pressure. A “U Tube” manometer having a scale range
from 0 to 12 inches of water should be used for this measurement. The
manifold pressure must be measured with the burner and pilot operating.
Any major changes in the flow must be made by changing the size of the
burner orifice.
Check Thermostat
Check thermostat operation. When set above room temperature or
temperature shown on the thermostat, the main burner should light.
Make certain the thermostat turns off the heater when room temperature
reaches the selected setting and starts the heater when room
temperature falls a few degrees.
Check the Gas Input (Natural Gas Only)
Under-firing could cause inadequate heat, excessive condensation or
ignition problems. Over-firing could cause shooting flame impingement
or overheating of the combustion chamber.
Before starting natural gas input check, obtain heating value of gas (BTU
per cubic foot) at standard conditions from your local supplier.
To measure the input using the gas meter, proceed as follows:
Step 1: Turn off gas supply to all other appliances except the heater.
Step 2: With the heater operating, time the smallest dial on the meter for
one complete revolution. If this is a 2 cubic foot dial, use the time in
seconds as is. (3,600 = Sec. Per Hr.) This gives the seconds per cubic
foot of gas being delivered to the heater.
Step 3: Assuming natural gas with a heating value of 1,000 Btu per
cubic foot and 34 seconds per cubic foot as determined by Step 2 then,
input: 1,000 x 3,600 34 = 106,000 Btu Per hour. This measured input
must not be greater than the input indicated on the rating plate of the
heater.
Step 4: Relight all other appliances turned off in Step 1 above and verify
all pilot burners are operating.
Warning
Warning
Danger of property damage, bodily injury or death.
Liquified petroleum (L.P.) gas is heavier than air and it will
settle in any low area, including open depressions and it
will remain there unless area is ventilated. Never attempt
start-up of unit before throughly ventilating area.

Natural gas heating value (Btu per cubic foot) can vary
significantly; therefore, it is the installer’s responsibility to see that
the Btu input to the heater is adjusted properly. Failure to do so
could cause combustion chamber failure, asphyxiation, fire or
explosion, resulting in property damage, bodily injury or death.
Refer to the National Fuel Code (NFPA-54) to be sure the heater
is burning fuel at the proper rate.

Burner Flame Characteristics
Start the furnace and let it operate at least 10 minutes. Open the
access door to view the burner flame. Limit your movements near
the furnace a few more minutes before making your final
observations. The flame may look yellow due to dust particles in
the room air. The flame should change to a nice blue color with firm
inner and secondary cones. An occasional flash of orange might be
seen as dust particles burn in the flame. This is normal. No burner
adjustment is provided, or is necessary. (Figure 8).
Normal Appearance
Natural Gas:
1. Inner cone - blue color - 3/8 to 5/8 inch above ports
2. Secondary inner cone - light blue - 1 to 2 inches above ports
3. Total flame - from blue to nearly invisible - approximately 6 inches
above ports.
L.P. Gas:
1. Inner cone - blue color - 1/2 to 3/4 inch above ports.
2. Secondary inner cone - light blue - 1 to 2 inches above ports.
3. Total flame - from blue to nearly invisible - approximately 6
inches above ports.
Abnormal Appearance
Lazy Flame
Long soft yellow cones moving around in the combustion chamber
lifting from ports (insufficient air).
Extremely Fast Flame
Will not hold to ports - entire cone sections blow off from noisy ports
(too much pressure).
Warning
If flame appears abnormal, contact the gas company or a qualified
service technician immediately.
Check Pilot Burner
The pilot flame must envelop 1/2- to 5/8-inches of the generator.
Pilot flame is preset at the factory, so ordinarily does not require field
adjustment. (Figure 7). On new installations, the gas lines will be
filled with air and may take several minutes to establish a pilot flame.

To Remove Logs from Combustion Chamber
Always remove the logs from the combustion chamber when cleaning
the burner or combustion chamber.
1. As parts are removed, place them in a safe place until ready for
reassembly.
2. Remove the chrome hearth assembly. Compression clips hold
hearth assembly in place. Grasp assembly frame and pull forward.
3. Remove the screws in the glass window frame.
IMPORTANT- The logs are made of special light weight materials that
can be easily damaged by rough handling.
4. Lift the front log up and out of the front log support brackets
carefully. Take care when pulling it out through the window
opening. Do not scrape it against the metal edges of the opening.
5. Remove the screws and plates holding the top right and top left
sides of the rear log set against the top rear support brackets.
6. Lift the rear log set up and out of the bottom support brackets. Tilt
the top towards the back and slowly allow the bottom to pass
through the opening first. Take care not to scrape it against the
metal edges of the opening.
7. Reverse the above procedure to reassemble after cleaning.
How to Care for Your Heater
Note: A properly adjusted burner with nearly all gasses will produce a flame which has clear blue cone having a bluish-red or bluish-violet
outer mantle.
Danger
A build up of any dust, lint or foreign material in the primary air
opening of the burner can interfere with the proper air gas mixture
and can result in a yellow flame which can produce carbon monoxide
and soot. This condition if allowed to develop, can lead to bodily
injury including death. It is imperative that the burner be kept clean.
Figure 11
Heater Area
Keep the area near the heater clear and free from combustible
materials, gasoline and other flammable liquids and vapors.
Combustion and Ventilation Air
The combustion and ventilation air supply must not be blocked.
Do not put anything in or on the heater cabinet. For better circulation
and more effective heating, do not place obstructions, furniture or other
items closer than four feet to the front of the cabinet or two feet from
each side of the cabinet.
Annual Upkeep Needed
It is recommended that a qualified service technician perform these
checks at the beginning of each heating season.
Cleaning Blower (If Equipped)
Shut off electricity. Clean any lint or dirt from fan blades, fan motor and
exposed air passages. Annually put two drops of SAE 20 oil in each of
the two cups or oil tubes.
Pilot Burner
Light pilot using instructions in “OPERATING INSTRUCTIONS”. Leave
thermostat at lowest setting. Pilot flame should surround 1/2 to 5/8
inches of the generator tip. If flame needs adjusting, do so as follows:
Adjust Pilot Burner
1. Remove screw cover over pilot adjusting screw.
2. Insert small screwdriver. Adjust flame as needed. Turn screw
counterclockwise to increase flame, clockwise to
decrease.
3. Turn thermostat to highest setting. Main burner should light quickly
and smoothly. Turn thermostat to lowest setting. Main burner
should go out. Pilot should remain lit.
4. Replace screw cover with gasket over pilot adjusting screw. Refer
to Figure 10.
Vent System
Make sure that no parts of the venting system are blocked or rusted.
Clean or replace before using heater.
Cleaning Burner Compartment
Because cold air is attracted to the flame during heater operation, a
build up of lint from carpeting, bedding, dust, etc. in the burner area will
occur. It is necessary to clean this area regularly. Use a vacuum
cleaner with a narrow attachment to reach small areas. Be careful in
and around the pilot. A change in its adjustment could be made if
moved during cleaning.
Glass Cleaning
Use mild soap and water only. Never clean when glass is hot.
If the glass is broken it must be replaced with the manufacturer’s
authorized part only. Failure to do so could cause property damage,
bodily injury or death.
Cabinet Finish
Clean cabinet with damp cloth. Never use abrasive cleaners.
Cabinets are finished with heat resistant powder paint.
-DO NOT refinish with wall or spray paint.
Removable Cabinet Top (350, 500, & 650 Model Series)
For ease of cleaning, access or replacement of internal parts, the top of
this heater can be removed by following these steps:
1. Remove three (3) brackets on rear of heater securing cabinet top
to back plate.
2. Pull cabinet top forward and lift up. Reinstall cabinet top by reversing
the procedures noted above. (Figure 9).

Troubleshooting
Symptom Possible Causes Corrective Action
1. Pilot will not stay lit after
carefully following lighting
instructions.
A. Generator producing insufficient millivolts. Check pilot flame. It must impinge on the
generator. Be sure generator is fully inserted in
bracket.
B. Loose or dirty generator connections at gas
valve. Clean and/or tighten connections at valve.
C. Generator defective. Check generator with millivolt meter. Take
reading at the generator terminals of the valve
with the valve placed in "Pilot" position.
Disconnect the thermostat wires. The millivolt
reading should be 450 millivolts or more.
D. Grounded thermostat wire. Remove thermostat wires from valve terminals.
If pilot now stays lit, trace thermostat wiring
circuit for a ground. May be grounded to
furnace, gas supply, nails or staples.
E. Defective valve. Replace gas valve after above is verified.
2. Pilot burning - no gas to the
main burner. A. Thermostat not turned to a position calling for
heat. Set thermostat to a position calling for heat.
B. Plugged burner orifice. Clean or replace.
C. Improperly wired or broken thermostat wires.
Defective thermostat. Check connections at valve terminals. If valve
operates, check thermostat wires.
D. Pilot generator may not be generating sufficient
millivoltage to open valve. See 1A and 1C above.
E. Defective valve. Replace.
3. Furnace operates but turns
"OFF" before room temperature
is attained.
A. Thermostat location. Check thermostat location. It should not be in
the path of warm air discharge from furnace,
near a lamp, or above a T.V. or stereo.
B. Defective thermostat. Check thermostat calibration or replace.
4. Furnace not producing sufficient
heat. A. Furnace may be too small for space being
heated. Check heat sizing calculations.
B. Furnace not burning at full rate. Check for low gas pressure at gas valve. It
should be 4 inches W.C. for Natural Gas; 10.5
inches W.C. for L.P.G. Check for blocked
burner orifice.
5. Furnace operates, but will not
shut off after room temperature
is attained.
A. Thermostat wiring defective. Thermostat lead wires may be shorted together,
caused by a nail or staple. Check by removing
thermostat leads from valve terminals.
B. Thermostat location. Check thermostat location. If on an outside wall,
or there is a hole in the wall behind thermostat,
cold air may be coming in contact with the
thermostat. Relocate the thermostat.
C. Defective thermostat. Verify thermostat temperature reading or
replace.
D. Valve stuck open. Replace valve.
6. Pilot outage. A. Pilot flame may be low or blowing (high),
causing pilot to drop out. Adjust pilot flame. Pilot orifice may be plugged
(check for spider webs or other material).
B. Drafts or drafty areas. Check for doorway and high movement areas.

Troubleshooting
Symptom Possible Causes Corrective Action
7. Main burner will not stay on. A. Blockage in vent pipe. Checks vent pipe for blockage, such as bird
nests, twigs, leaves, etc.
Check that the vent cap is properly installed,
and not placed to far down on the vent pipe.
Cap must be the same manufacturer as the
vent.
B. Vent to short. The vent should terminate a minimum of 12 feet
above floor plate. The top of the vent must be
at least 2 feet above any obstacle within a 10
foot radius, including the roof.
C. Restriction in vent system caused by offsets. All type "B" vents shall extend in a vertical
direction with offsets not exceeding 45 degrees.
Any angle greater than 45 degrees from vertical
is considered horizontal. Any offsets used
should be as far above the drafthood as
possible to allow venting to begin before any
restriction is encountered. The use of too many
offsets may also prevent proper venting.
D. Incorrect vent pipe. Use listed B/W type vent pipe. DO NOT use
transite or any other type of ceramic pipe for
venting. DO NOT use single wall pipe. When
venting into a masonry chimney, the chimney
must be properly lined and sized for this gas
furnace. The use of type "B" or flexible chimney
liner is recommended.
E. Loose connections on the vent safety wiring
harness. Check the connection on both the switch and
the gas valve. Tighten if necessary.
8. Abnormal operation. A. Delayed ignition - pilot flame may be too low. Adjust pilot flame. Refer to "How to Care for
Your Heater" section in this manual.
B. Expansion noise, ticking. Heater may be distorted by being vented
through an uneven opening. A restricted vent
may create expansion noise. Refer to "Venting"
section of this manual.
C. Combustible gas spillage. Check vent system for a blocked flue, excessive
down draft (wind) or negative pressure in room
caused by ventilating fan or a fire in a fireplace.
D. Excessive flame roll-out. Furnace is possibly overrated - check for high
gas pressure at gas valve (see 4B).
E. Burner is over-fired. Check the manifold gas pressure. Check the
rate, this appliance is manufactured for
elevations up to 4,500 feet. It must be derated
for operation above 4,500 feet.
F. Yellow burner flame. Check burner for obstructions. Install new
burner and pilot orifices.
G. Yellow pilot flame. Remove pilot orifice, check and clean.
9. Noisy blower. A. Housing rattling. Tighten blower screws.
B. Blower dirty. Clean blower wheel.
C. Blower wheel bent. Straighten or replace.
10. Blower does not run. A. Fan switch not set. Select fan speed.
B. Check bearings. Add oil as outlined in "Blower Accessory
Instructions".
