Start-Up & Adjustment BEFORE PLACING THE UNIT INTO OPERATION Smell all around the appliance area for gas. Be sure to smell next to the floor because LP/Propane gas is heavier than air and will settle on the floor. Use only your hand to move the gas control switch. Never use tools. If the switch will not move by hand, do not try to repair it. Force or attempted repair may result in a fire or explosion. A - Placing the Unit into Operation IMPORTANT See Table 1 for supply line pressure.

C - Gas Flow (Approximate) NOTE: To obtain accurate reading, shut off all other gas appliances connected to meter. Unit Capacity Furnace should operate at least 5 minutes before checking gas flow. Determine time in seconds for two revolutions of gas through the meter. (Two revolutions assures a more accurate time.) Divide by two and compare to time in Table 2. If manifold pressure matches Table 1 and rate is incorrect, check gas orifices for proper size and restriction.
