7. When counting pipe elbows, this includes all elbows, or equivalent pipefittings, used inside the
furnace jacket in addition to those used to construct the termination. Each 90° elbow is the
equivalent of 5 feet of pipe length. Furthermore, two (2) 45° elbows can be substituted for one (1)
90° elbow.
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 5 ft of pipe with two (2) 90 deg. elbows. This is
separate from the elbows used at the termination and those inside the furnace cabinet.
8. 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. All pipe joints must utilize
standard PVC Schedule 40 series, DWV type elbows, couplings, and fittings. 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.
Piping joints inside the furnace vestibule should be sealed with silicone caulk, rather than pipe
cement, to allow for disassembly and removal of piping, if necessary, during maintenance.
