COMBUSTION AND VENTILATION AIR
When installed, this gas appliance must be provided with flesh 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 bin/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 flee area of one square inch per 1,000 bm 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 Fimlre A.
If the home is of unusually tight construction (new and remodeled homes), tree 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 comlnunicate 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 flee area of one square inch per 4,000 btu/hr of total
input rating of all gas appliances. See Fimlre B and C. If horizontal ducts are used,
the minimum flee 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
colrnnencingwithin 12inches oftheceiling. Theminimum free areaofthis opening
shall be one square inch per 3,000 bm/hr ofthe total input rating ofatl gas appliances
but not less than the sum of the areas of all vent connectors in the space. See
Fibre D.
When calculating the amount of fresh air needed you must include make-up air
requirements tbr the operation of exhaust fans, kitchen ventilation systems, clothes
dryers, and fireplaces.

VENTING
This appliance must be properly connected to a venting
system. Consult local ordinances governing venting. Install only
UL listed type BW 4" oval gas vent. When the vent enters the
attic, a listed type B- 1 round flue pipe may be used. See Figure
2, Page 7.
Vent pipe must connect to the wall furnace header plate
with a"B" vent base plate and terminate with a cap at a point at
least 12 foot above the bottom of the wall furnace, two feet
above any obstacle within a 10 foot radius, and at least 3 foot
above the roof.
Provisions must be made for adequate combustion and
ventilation air.
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.
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 offthe 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.
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.
Page 5
WARNING: Do not bypass the blocked flue
switch. To do so could expose the consumer to
property damage, personal iniury or possible death.
