WARNING: Do not bypass the vent safety shutoff switch. To do so could expose the consumer to property damage, personal injury or possible death. The switch, when activated, will extinguish the pilot flame. If the homeowner experiences this problem, the vent system must be checked and corrected. NOTE: An existing vent that has worked for years may not be adequate for todays design because of higher efficiency requirements resulting in lower stack temperatures. The following is a list of possible causes and corrective actions. POSSIBLE CAUSES CORRECTIVE ACTION 1. Blockage in vent pipe 1.A) 1.B) Check vent pipe for blockage, such as bird nest, wasp nest, twigs, leaves, etc. Check that the vent cap is properly installed, not shoved too far down on the vent pipe. 2. Burner is over firin 2.A) 2.B) Check the manifold pressure. 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 main burner orifice section of instructions for proper orifice size and re-orifice accordingly. 3. Improper vent system A) Vent too short B) Restriction in vent system caused by offsets 3. A) B) Correct vent system. The vent should not terminate less than 5 feet above the drafthood connection. A gas vent extending through an exterior wall shall not terminate adjacent to the wall or below eaves or parapets. Also, the top of the vent must be at least 2 foot above any obstacles within a 10 foot radius, including the roof. See Figure A. All type “B” vent 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 “B” type vent pipe. Do not use transite or any other type of ceramic pipe for venting. Do not use single wall pipe. 4. Loose connections on the vent safety wiring harness 4. Check the connection on both the switch and the gas valve. Tighten if necessary.
