COMBUSTION AND VENTILATION AIR ALL COMBUSTION AIR FROM ADJACENT INDOOR SPACES When installed , this gas appliance must be provided with flesh air for combustion , THROI _ YGHINDOOR COMBrcYSTION AIR OPENINGS 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 . UL Listed Vent Cap Vent 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 .

VENTING USING ADJACENT STUD SPACE FOR ALL COMBUSTION AIR This appliance must be properly connected to a venting FROM OUTSIDE system . Consult local ordinances governing venting . Install only HOLES CONNECTING UL listed type BW 4 " oval gas vent . When the vent enters the TO VENTILATED ATTIC 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 CEILING least 12 foot above the bottom of the wall furnace , two feet PLATE 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 . AIR Discoloration of the grille is an indication of a bad vent . If this GRILLE occurs , the vent can be checked by a qualified serviceman using a draft gauge . After 15 minutes the gauge should read between FLOOR - . 02 up to - . 04 inches w . c . Vent must be checked at the PLATE beginning of each heating season . The switch when activated on a bulb control burner will HOLES CONNECTING TO extinguish the pilot flame , on a thermostat controlled burner , the VENTILATED CRAWL thermostat circuit will be broken , turning offthe main burner flame . Before the heater can be relit , the reset button must be SPACE activated . See Figure B for location of the manual reset blocked flue switch . To reset the switch , insert a slender rigid object BASED ON 4,000 BTU OF TOTAL INPUT ( i . e . screwdriver ) through the front panel louvers and push the RATING OF ALL GAS APPLIANCES , THE reset button down . See Figure B - 1 . However , you may have HEATER ONLY REQUIRES A MINIMUM to remove the front panel , then reset the switch and reinstall the FREE AREA OF : front panel to relight heater .

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
