EXISTING CLASS “A” CHIMNEY: Run 4” Class “L” connector from the furnace connection to a positive connection with the class “A” chimney. AN APPROVED 4” LINER MUST BE USED IN CLASS “A” CHIMNEYS. Make sure each joint is firmly locked in place. Make sure the attachment of Class “L” to the Class “A” chimney is secure with sheet metal screws. Seal all joints with high temperature silicone. Class “L” connector should maintain a pitch on rise from the furnace to the chimney of at least .” per foot. A): “L” Vent connector 4” B): “L” Vent elbow 90° adj. 4” EXISTING MASONRY CHIMNEY: Run 4” Class “L” connector from the furnace connection to a positive connection with the masonry chimney. Make sure each joint is firmly locked in place. Make sure the penetration of the Class “L” connector into the masonry chimney is sound and secured with high temperature cement. Seal all joints with high temperature silicone. Class “L” connector should maintain a pitch on rise from the furnace to the chimney of at least .” per foot. AN APPROVED 4” LINER MUST BE USED IN MASONRY CHIMNEYS. Your new furnace is so efficient; an unlined chimney could remain cold and cause a downward pressure creating poor burning, incomplete combustion or back draft.

Run Class “L” chimney all the way from the furnace connection to point of termination. Make sure each joint is firmly locked in place. Seal all joints with high temperature silicone. Class “L” connector should maintain a pitch on rise from the furnace to the chimney of at least .” per foot. A.) Vertical top 4” D.) Adj. flashing 4” B.) “L” Vent pipe 4” E.) Fire stop spacer 4” C.)

Class “L” connectors shall be installed without any downward pitch from the appliances and without any dips or sags. 2. Class “L” connectors shall be pitched upward from the appliance at least .” per foot. 3. Class “L” starter adapter shall be firmly attached to the vent outlet collar of the furnace and a positive seal made with high temp silicone, approved metal tape and/or sheet metal screws. 4. The chimney shall extend at least three (3) feet above the highest point when they pass through the roof of the building and at least two (2) feet higher than any portion of any building within ten (10) feet. COMBUSTION AIR: Furnaces must have air (oxygen) for proper performance. The incomplete combustion that takes place when a furnace is “air starved” causes carbon monoxide (CO) to be formed in quantities that can be dangerous inside a well-sealed house. Having a source of combustion air from outside prevents this “air starvation” of the furnace. Provisions for combustion air shall be made in accordance with applicable provisions of local building codes. The GBU070 combustion air intake is the slot on the back of the unit. Keep this opening free of obstructions which would restrict airflow. Text Box: Text Box: Text Box: HIGH BUILDING OR SECTION OF BUILDING DUCTING PRIMARY FURNACE To install the GBU070 as a “Primary Furnace” first locate the furnace as near the chimney and as centralized with respect to heat distribution as practical. Follow all clearance to combustible requirements. Connect the ductwork to the furnace. Minimum supply plenum size: 14” x 14”, minimum return plenum size: 12” round. When a furnace is installed so that supply ducts carry air circulated by the furnace to the areas outside the space containing the furnace, the return air must also be handled by a duct sealed to the furnace casing and terminating outside the space containing the furnace. Where there is no complete return duct system, the return connection must be run full size to a point outside the furnace room. Air duct systems should be installed in accordance with standards for air conditioning systems. NFPA Pamphlet #90. They should be sized in accordance with ACCA Manual D or whichever is applicable, after completing installation as per the appropriate section of this manual. Text Box: ELECTRICAL REQUIREMENTS 1. Make sure that the power source conforms to the requirements of the furnace. Disconnect the power source before performing any maintenance or electrical work. 2. Connect the electrical power according to the appropriate wiring diagram on the following page. 3. Plug the power supply into a surge protected and grounded 15-amp branch circuit. The outlet must have the correct polarity. With a voltage tester, check the outlet and make sur...
