Care should be taken to design the shortest possible intake and exhaust systems. Each system should contain as few elbows as possible to insure the satisfactory operation of the furnace. However, system length should never be less than 8 ft of pipe with two (2), 90 deg. elbows. For best overall operation of the combustion system, we recommend the actual equivalent lengths for both the constructed intake and the exhaust systems have approximately the same value.

9.The furnace comes with two 3” street elbows. The first street el shall be affixed to the secondary outlet collar either for left or right hand venting direction. First slide the black radiator hose (parts bag) over the metal exhaust collar. Next, slide 2 band clamps over the radiator hose. Then insert the PVC street el into the collar making sure to push the elbow all the way in until it stops. Finally the band clamps can be positioned and tightened. If you are venting left or right, simply continue venting with 3” PVC making sure to seal all connections. If you desire to vent thru the top right of the cabinet, utilize the second street el and line it up accordingly. (See Figure 1)

10.Use a saw designed to cut thermoplastic pipe. All cuts should be made at right angles to the pipe wall. Smooth jagged edges and remove all burrs and strings. Clean all pipe surfaces at connections using a fine abrasive material or approved PVC cleaner (primer). Secure all pipe joints using suitable permanent PVC pipe solvent cement. Joints are NOT to be made by simply gluing raw edges of butted together vent pipe.

Notice: Piping joints inside the furnace vestibule should be sealed with silicone caulk, rather than pipe cement, to allow for disassemble and removal of piping, if necessary, during maintenance.

Notice: Use silicone caulk to seal the pipe to the metal air intake collar on the burner, and then secure with a sheet metal screw.

11.Vent connections shall be visually checked for leakage.

12.Vent pipe passing through an unheated space shall be insulated with 1-inch thick, foil-faced
