Pipe Tapered thread (BSPT), order 44178804 brass
female NPT (FPT) to male BSPT gas pipe thread
adapter, available at extra cost.
3. Connect to gas supply pipe using thread sealant or Teflon
tape. Torque 90 - 175 inch-pounds [10.2 - 19.7 Nm].
NOTE: The connection of gas supply to the appli-
ance shall be made with a flexible hose suitable for
the appliance category in accordance with national
installation regulations of the country of destina-
tion. If in doubt contact the dryer distributor or man-
ufacturer.
NOTE: When connecting to a gas line, an equipment
shut-off valve in accordance with the National Fuel
Gas Code, ANSI Z223.1/NFPA 54 and the Natural
Gas and Propane Installation Code, CSA B149.1
must be installed within 6 feet [1.8 m] of the dryer.
