See Figure B. Maintain equal distance between spring spacers. 3. Remove the 6-." dia. Vent collar from the fireplace. Replace this collar with the 7" dia. Flex Vent adapter collar provided with the vent kit. 4. Slide the Flex Vent flue pipe into the Outer Flex Vent pipe. 5. Install the Wall Firestop/Thimble assembly as required through the wall. Refer to the venting charts in the fireplace manual to determine the proper height and size of the vent opening. The minimum opening should be 9" wide b

3. Run the other end of the duct through the exterior wall cutout. 4. From the outside of the building, connect the duct to the collar on the outside air vent assembly with band clamp or screws to secure. 5. Mate the outside rain cap hood over the air vent, seal with caulk as necessary, then secure with screws provided to the exterior wall surface. See Figure 22 and 23. 6. Figure 24 illustrates the various options for installation of the air duct run possibilities. OUTSIDE HOOD 4” DIA. AIR DUCT

Insert natural gas front burner bushing into throat (Venturi) of front burner. See Figure 45. 11. Replace front burner with one (1) screw from Step 8. 12. Remove rear burner (one (1) screw). 13. Use 3/8” socket or wrench to remove propane gas rear burner orifice marked 1.45 from orifice fitting. Replace with natural gas rear burner orifice marked 43 into orifice fitting. 14. Replace rear burner with one (1) screw from Step 12. 15. Connect caps and plugs on flame sensor and hot surface ignitor. 1

The maximum allowable reduction in manifold pressure for Natural gas shall be from 3.5” w.c. (.872 kPa) to 2.8” w.c. (.697 kPa). The maximum allowable reduction in manifold pressure for Propane (LP) gas shall be from 10.0” w.c. (2.49 kPa) to 8.0” w.c. (1.99 kPa).

Then take the same immediate action recommended above for the occasion when you do detect the odorized LP-Gas. • If you experience a complete “gas out,” (the container is under no vapor pressure), turn the tank valve off immediately. If the container valve is left on, the container may draw in some air through openings such as pilot light orifices. If this occurs, some new internal rusting could occur. If the valve is left open, then treat the container as a new tank. Always be sure your contain

This should consist of a vertical length of pipe tee connected into the gas line that is capped on the bottom in which condensation and foreign particles may collect. The use of the following gas connectors is recommended: — ANS Z21.24 Appliance Connectors of Corrugated Metal Tubing and Fittings — ANS Z21.45 Assembled Flexible Appliance Connectors of Other Than All-Metal Construction The above connectors may be used if acceptable by the authority having jurisdiction The state of Massachusetts re
