COMBUSTIONAND VENTILATIONAIR  
When installed, this gas appliance must be provided with fresh air for combustion, ventilation, and dilution of hot  
flue gases. The minimum required volume of the area where the appliance is installed should be 50 cubic feet per  
1,000 btu/hr.  
If installed in an area of the home that is considered an unconfined space, the natural infiltration of air around  
windows and doors will be adequate. If the area is considered a confined space (less than 50 cubic feet per  
1,000 btu), fresh air can be supplied by providing two permanent openings into adjoining rooms. Each opening  
shall have a minimum free area of one square inch per 1,000 btu per hour of the total input rating of all gas  
appliances in the confined space, but not less than 100 square inches. One of the openings shall be within 12  
inches of the ceiling and one within 12 inches of the floor. See FigureA.  
If the home is of unusually tight construction (new and remodeled homes), free air must be supplied through  
opening(s) to the outdoors. This can be accomplished by providing 2 permanent openings, one commencing  
within 12 inches of the ceiling and one within 12 inches of the floor. These openings shall communicate directly  
with the outdoors, or spaces that communicate freely with the outdoors, such as a ventilated attic and crawl space  
through galvanized or equivalent corrosion-resistant ducts. Exception: unobstructed stud and joist spaces are  
acceptable ducts provided that not more than one fire block is removed. Special provisions must be taken to  
insure that these stud and joist spaces cannot be blocked with insulation or other objects. Each of these openings  
using vertical ducts shall have a minimum free area of one square inch per 4,000 btu/hr of total input rating of all  
gas appliances. See Figure B and C. If horizontal ducts are used, the minimum free area shall be one square inch  
per 2,000 btu/hr of total input rating of all gas appliances.  
Fresh make-up air can also be provided through a duct to one permanent opening commencing within 12 inches  
of the ceiling. The minimum free area of this opening shall be one square inch per 3,000 btu/hr of the total input  
rating of all gas appliances but not less than the sum of the areas of all vent connectors in the space. See Figure D.  
When calculating the amount of fresh air needed you must include make-up air requirements for the operation of  
exhaust fans, kitchen ventilation systems, clothes dryers, and fireplaces.  
Additional information can be found in the latest edition ofANSI Z223.1 (National Fuel Gas Code).

CEILING  
PLATE  
Provisions must be made for adequate combustion and  
ventilationair.  
This appliance is equipped with a manual reset blocked  
flue switch designed to protect against a blocked flue condition,  
which would cause combustion products to spill back into the  
living quarters. NOTE: A partially blocked, inadequate, or  
disconnected vent system may not activate the switch.  
Discoloration of the grille is an indication of a bad vent. If this  
occurs, the vent can be checked by a qualified serviceman using  
a draft gauge. After 15 minutes the gauge should read between  
-.02 up to -.04 inches w.c. Vent must be checked at the  
beginning of each heating season.  
AIR  
GRILLE  
FLOOR  
PLATE  
The switch when activated on a bulb control burner will  
extinguish the pilot flame, on a thermostat controlled burner, the  
thermostat circuit will be broken, turning off the main burner  
flame. Before the heater can be relit, the reset button must be  
activated. See Figure B for location of the manual reset blocked  
flue switch. To reset the switch, insert a slender rigid object  
(i.e. screwdriver) through the front panel louvers and push the  
reset button down. See Figure B-1. However, you may have  
to remove the front panel, then reset the switch and reinstall the  
front panel to relight heater. If homeowner experiences this  
problem, the vent system must be checked and corrected.  
NOTE: A pre-existing vent that has worked for years may not  
be adequate for todays design because of higher efficiency  
requirements that result in lower stack temperatures. See  
“Possible Causes and Corrective Action” on Page 16.

PILOT ADJUSTMENT  
MAINTENANCE INSTRUCTIONS  
Locate the pilot adjustment screw on the valve. The pilot  
flame should surround at least the top 3/8” of the powerpile  
(pilot generator) or thermocouple (see below). The pilot is  
unregulated so it will be operating at inlet line pressure (Max.  
7” w.c. for natural gas and 11” w.c. for propane). To decrease  
the pilot flame, turn the screw clockwise (approximately seven  
to nine full turns to bottom of pilot light channel) until you  
produce sufficient flame at the minimum noise level.  
1.  
Installation and repair should be done by a qualified  
service person. The appliance should be inspected before  
use and at least annually by a professional service person.  
More frequent cleaning may be required due to excessive  
lint from carpeting, bedding material, etc. It is  
imperative that control compartments, burners, pilot  
burners, circulating air passageways and venting systems  
of the appliance be kept clean.  
2.  
3.  
If the appliance has been equipped with the optional  
WFF81-C fan kit assembly, the bearings of the motor  
should be oiled every six months with approximately 2  
drops of S.A.E. 20 oil.  
PILOT FLAME ADJUSTMENT  
3/8 TO 1/2 INCH  
The appliance area must be kept clear and free of any  
combustible materials, gasoline and other flammable  
vapors and liquids.

Select left or right side of front panel for most convenient location of the temperature control knob. Remember  
to choose the side that allows adequate clearance for accessibility to adjust the control knob.  
STEP 2.  
On selected side, locate three (3) vertical dimples beginning approximately 20-½” above bottom of the front  
panel. See Figure 9.  
*On Gravity Wall Furnaces manufactured prior to November 2005 (without bracket hole dimples in the left  
and right side), you may use the gravity BBSK bracket as a template to locate holes. Measure 20-1/2” up on  
the preferred side, to locate lowest hole.  
STEP 3.  
STEP 4.  
STEP 5.  
Using these three (3) dimples as locator, drill three ¼” holes.  
Remove the BBSK control switch from the packing set. See Figure 10.

STEP 6.  
Place BBSK control switch inside front panel, align engagement holes with clearance holes in P/N 40230 heat  
shield and the ¼” drilled holes in the front panel. Attach using two (2) #8x½” screws provided. Make sure  
heat shield is between the BBSK control switch and the heat exchanger.  
STEP 7.  
Connect each end of the black wires to the two outside terminals on the BBSK control switch, route wires  
down the inside of the front panel. See Figure 11.  
STEP 8.  
Straighten the bulb capillary tube using extreme care not to bend or damage the tube, route the tube down the  
inside of the front panel.  
STEP 9.  
Install the front panel onto the wall furnace.  
Insert the control knob onto the control rod. See Figure 10.  
Open the front panel door.

BBSK KIT LIGHTING INSTRUCTIONS  
FOR YOUR SAFETY READ BEFORE LIGHTING  
WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing  
property damage, personal injury or loss of life.  
A.  
This appliance has a pilot which must be lighted by  
hand. When lighting the pilot, follow these instruc-  
tions exactly.  
If you cannot reach your gas supplier, call the fire  
department.  
B.  
BEFORE LIGHTING smell all around the  
appliance area for gas. Be sure to smell next to the  
floor because some gas is heavier than air and will  
settle on the floor.  
C.  
Use only your hand to push in or turn the gas control  
knob. Never use tools. If the knob will not push in  
or turn by hand, don’t try to repair it, call a qualified  
service technician. Force or attempted repair may  
result in a fire or explosion.  
WHAT TO DO IF YOU SMELL GAS:  
Do not try to light any appliance.  
Do not touch any electric switch; do not use any phone  
in your building.  
Immediately call your gas supplier from a neighbor’s  
phone. Follow the gas supplier’s instructions.  
D.  
Do not use this appliance if any part has been under  
water. Immediately call a qualified service technician  
to inspect the appliance and to replace any part of the  
control system and any gas control which has been  
under water.

TROUBLE SHOOTING CHART - BLOCKED FLUE SWITCH (FOR USE BY A QUALIFIED SERVICEMAN)  
POSSIBLE CAUSES  
1. Blockage in  
vent pipe  
CORRECTIVE ACTION  
A. Check vent pipe for blockage, such as bird nest, wasp nest, twigs, leaves, etc.  
B. Check inside the bottom of the vent pipe to make sure the top of the draft diverter did not  
rip the inner liner causing it to block part of the vent opening.  
C. Check that no insulation from the header plate got caught on top of the draft diverter when  
the heater was inserted into the wall.  
D. Check that the vent cap is properly installed, not shoved too far down on the vent pipe.  
A. Check the manifold pressure.  
B. Check the rate, NOTE: This appliance was orificed for elevations up to 2,000 feet. When  
installed at higher elevations refer to orifice chart in controls section of instructions for  
proper orifice size and re-orifice accordingly.  
2. Burner is  
overfiring  
3. Improper vent  
system  
3. Correct vent system.  
A. Vent too short  
A. The vent should terminate a minimum of 12 feet above the floor. See Figure 2. Also, the  
top of the vent must be at least 2 foot above any obstacle within a 10 foot radius, including  
the roof. See Figure A.  
B. Restriction in  
vent system  
caused by offsets  
B. All type “B” vents shall extend in a generally vertical direction with offsets not exceeding 45  
degrees, except that a vent system having not more than one 60 degree offset may be allowed.  
Any angle greater than 45 degrees from the vertical is considered horizontal. The total  
horizontal run of a vent plus the horizontal vent connector shall be not greater than 75 percent  
of the vertical height of the vent.  
Any offsets used should be as far above the drafthood as possible to allow a venting action to  
begin before any restriction is encountered.  
C. Incorrect vent pipe C. Use listed BW type vent pipe. Do not use tansite 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.  
4. Incorrect header  
plate location  
4. The header plate must be 65-3/4” above the floor plate. See rough-in instructions.  
5. Vent pipe not down 5. Use a base plate (obtained from the vent pipe manufacturer) on top of our header plate.  
on the header plate  
securely  
This will lock the vent pipe down and prevent the draft diverter from shoving it up.  
6. Loose connections  
on the vent safety  
wiring harness  
6. Check the connection on both the switch and the gas valve. Tighten if necessary.  
DO NOT BYPASS THE BLOCKED FLUE SWITCH  
To do so could expose the consumer to property damage, personal injury or possible death.

IMPORTANT SAFETY BULLETIN ON YOUR GAS CONTROL AND PILOT LIGHT  
SYSTEM FOR HEATING EQUIPMENT  
WHAT YOU DON’T KNOW CAN HURT YOU.  
Your pilot light system has been designed for safe and reliable operation. Although safety mechanisms are built-in,  
the potential for hazard exists. This information is intended to help you avoid these hazards.  
YOUR GAS CONTROL AND PILOT LIGHT  
WHAT TO DO IF YOU SMELL GAS . . .  
Do not try to light any appliance.  
SYSTEM  
Your gas control and pilot light system has a safety  
Do not touch any electrical switch; do not use  
device whose purpose is to shut-off the gas supply to  
the appliance if the pilot light goes out. If you have  
any phone in your building.  
Immediately call your gas supplier from a  
trouble lighting the pilot or keeping it lit, it may mean  
that this safety device is warning you that there is a  
problem with your system. Inspection and repairs or  
replacement must be made by a trained gas service  
technician.  
neighbor’s phone. Follow the gas supplier’s  
instructions.  
If you cannot reach your gas supplier, call the  
fire department.  
Installation and service must be performed by a  
qualified installer, service agency or the gas  
supplier.  
TAMPERING IS DANGEROUS  
The pilot safety system may also not work if you do  
not follow the lighting instructions carefully or if you  
tamper with the gas control that you use to light the  
pilot. Tampering with the gas control, particularly  
with tools, can damage the safety mechanism in the  
control and can allow gas to leak. This can result in a  
fire or explosion causing property damage, personal  
injury or death.  
Do not store or use gasoline or other flammable  
vapors and liquids in the vicinity of this or any  
other appliance.  
CRITICAL SAFETY POINTS TO REMEMBER . . .  
Your gas has been odorized so that you can smell it.  
Always smell around for gas before lighting your  
appliance.  
Sniff for L.P.-gas at floor level. LP-gas is heavier than  
air and may temporarily exist at floor level.  
IF YOU SMELL GAS, DON’T LIGHT IT  
If you smell gas, do not attempt to light the pilot. Do  
not cause a spark by turning on or off electrical  
switches or appliances or by using the phone. Turn off  
the gas to the appliances and call your gas supplier  
from another location.  
If your gas control has gotten wet as the result of  
flooding or other wetting, it must be replaced  
immediately by a trained gas service technician.  
Water can lead to damage of the internal safety  
mechanism in the gas control and can create a  
hazardous condition.  
IF YOU CAN’T LIGHT IT,  
DON’T FIGHT IT!
