Install the vent cap by inserting it into the air inlet tube and over the vent tube. OF VENT CAP EXTERIOR WALL IMPORTANT The top of the vent cap is embossed "TOP". Install it in the correct position to prevent water from entering the wall. Level the vent cap and attach it to the outside wall with four (4) #8 roundhead (long) screws (Fig. 6).
Gas Supply Gas control valve, within the furnace, is shipped with a seal over gas inlet tapping. Do not remove this seal until ready to connect piping. & Piping 2, Apply moderate amount of good quality dope to pipe only, leaving 2 end threads bare. If L.R Gas installation, use compound resistant to action of liquefied petroleum gases. WARNING DANGER OF PROPERTY DAMAGE, BODILY INJURY OR DEATH. MAKE SURE THE FURNACE IS EQUIPPED TO OPERATE ON THE TYPE OF GAS AVAILABLE.
