16 100353 FRESH AIR FOR COMBUSTION AND VENTILA TION W ARNING This heater must have fresh air for proper operation. If not, poor fuel combustion and improper venting of flue gases will result. Carbon monoxide poisoning from backed-up flue gases could occur.
17 100353 FRESH AIR FOR COMBUSTION AND VENTILA TION Continued DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION Example 1: Locating Heater in Unconfined (Open) Area NOTICE An unconfined area has a minimum air volume of 50 cubic feet for each 1000 BTU/Hr input rating of all appliances in the area (cubic feet equals length x width x height of area).
18 100353 FRESH AIR FOR COMBUSTION AND VENTILA TION Continued Figure 14 - Ventilation Air from Outdoors Draft Hood Spillage: This is a hazardous situation.
19 100353 FRESH AIR FOR COMBUSTION AND VENTILA TION Continued Example 2: Locating Heater in Confined (Closed) Area NOTICE A confined area has an air volume of less than 50 cubic feet for each 1000 BTU/Hr input rating of all appliances in the area (cubic feet equals length x width x height of area).
20 100353 OPERA TING HEA TER A. This appliance has a pilot which must be lighted by hand. When lighting the pilot, follow these instructions exactly. B. BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.
21 100353 5. Wait five (5) minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow “B” in the safety information at the top of page 20. If you don’t smell gas, go to the next step. 6. Turn control knob clockwise Clockwise to the PILOT position.
22 100353 MANUAL LIGHTING PROCEDURE 1. Remove lower front access panel on heater. 2. Locate pilot. Pilot is attached to the front of burner. 3. Follow steps 1 through 6 under Lighting Instructions , pages 20 and 21. 4. With control knob depressed, strike match.
23 100353 Check pilot flame pattern and burner flame pattern often. PILOT FLAME PATTERN Figure 18 shows a correct pilot flame pattern. Figure 19 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will prevent the thermocouple from getting hot, causing the heater to shut down.
