PRODUCT DESIGN WARNING TO PREVENT DEATH OR SERIOUS ILLNESS TO BUILDING OCCUPANTS DUE TO FLUE PRODUCTS LEAKING INTO THE BUILDING, PROPER INSTALLATION OF GASKETS AND SCREWS IS ESSENTIAL FOR PROVIDING A GAS TIGHT SEAL BETWEEN THE PARTITION PANEL AND THE INDUCED DRAFT BLOWER. Make sure all wires are at least one inch from flue pipe. Relocate junction box to right side of cabinet if necessary. Refer to Electrical Connections section of this manual for instructions.
PRODUCT DESIGN Check 1 - Proper chimney termination. A masonry chimney used as a vent for gas fired equipment must extend at least three feet above the highest point where it passes through the roof. It must extend at least two feet higher than any portion of a building within a horizontal distance of 10 feet. In addition, the chimney must terminate at least 3 feet above any forced air inlet located within 10 feet.
PRODUCT DESIGN does not sound like metal hitting metal, the liner must be removed and replaced (Fix 4). Remember that all appliances must be vented inside the liner. Venting one appliance inside the liner and another appliance outside the liner is not acceptable. Next, use a flashlight and small mirror to sight up the liner. B vent must be supported so as to not come into direct contact with the chimney walls or tile liner. If it is not, it can probably be rehung so as to be acceptable.
PRODUCT DESIGN If none of the above options are practical, the 80% furnace may need to be vented vertically with B vent. Under some conditions a 90%+ furnace could be installed rather than an 80%. The 90% furnace can be vented horizontally or vertically through PVC pipe. Fix 3 - Rebuild the Crown. If the chimney crown is damaged, a qualified mason must repair it in accordance with nationally recognized building codes or standards.
PRODUCT DESIGN WARNING FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN BODILY INJURY OR DEATH. CAREFULLY READ AND FOLLOW ALL INSTRUCTIONS GIVEN IN THIS SECTION. WARNING UPON COMPLETION OF THE FURNACE INSTALLATION, CAREFULLY INSPECT THE ENTIRE FLUE SYSTEM BOTH INSIDE AND OUTSIDE THE FURNACE TO ASSURE IT IS PROPERLY SEALED. LEAKS IN THE FLUE SYSTEM CAN RESULT IN SERIOUS PERSONAL INJURY OR DEATH DUE TO EXPOSURE TO FLUE PRODUCTS, INCLUDING CARBON MONOXIDE.
PRODUCT DESIGN tabular listing of appropriate altitude ranges and corresponding manufacturer’s high altitude (Natural, Propane gas, and/ or Pressure Switch) kits. Do not derate the furnace by adjusting the manifold pressure to a lower pressure than specified on the furnace rating plate. The combination of the lower air density and a lower manifold pressure will prohibit the burner orifice from drawing the proper amount of air into the burner.
PRODUCT DESIGN 1. Use black iron or steel pipe and fittings for the building piping. 2. Use pipe joint compound on male threads only. Pipe joint compound must be resistant to the action of the fuel used. 3. Use ground joint unions. 4. Install a drip leg to trap dirt and moisture before it can enter the gas valve. The drip leg must be a minimum of three inches long. 5. Install a 1/8" NPT pipe plug fitting, accessible for test gage connection, immediately upstream of the gas supply connection to the furnace.
