Figure 2-3.—Spate heater (Type II). CAUTION Hold the sheet metal securely while curl- ing it to prevent it from slipping and causing severe cuts. 6. Assemble the smoke-pipe sections starting with the section of pipe having the damper installed. Place the smooth female end of the pipe over the steel collar on the heater top. b. From the inside, insert a split rivet through each of the three holes in the smoke-pipe sections. Spread the tines of the rivet, and hammer them flat. NOTE The damper is not required in the smoke pipe when it is burning liquid fuel. c. In one section of the smoke pipe, insert the damper. Punch a hole through the pipe at a position half the length of the pipe. Hold the damper in place inside the pipe, and thread the damper shaft through the holes locking the curved shank of the damper shaft into the center slot of the damper. When they are locked together properly, the damper and operating handle are parallel. NOTE When conditions permit, use six lengths of pipe extended straight up. Elbows and horizon- tal pipes reduce the draft and cut down the heat output. 7. Install the spark arrester on one pipe section above the heater or on top of the smoke pipe outside of the shelter. To assemble and set up the Type II space heater, refer to figure 2-5 and proceed as follows: 1. Place the adapter ring on the heater base. 2-9
