56 ON STARTUP: 1. Have s ystem inspec ted and s tarted b y a qualifie d heating contractor. 2. Check oil level in tank. If the tank has not been f illed w ith fresh oi l, inspec t the rem aining oi l for signs of contam ination with water, alg ae, dirt or other i mpurities .
57 : Do not use this appliance if any part has been un der wat er. Immediately call a qu alified s ervice techn ician t o inspe ct the furnace an d to rep lace any part of the control s y s tem and an y oil control that has be en under water.
58 If this ac tion does no t react ivate th e unit, cont act a qual ified serv ice agenc y for ass istance. In genera l, if the th erm ostat is set i n the heat ing mode, the heating system function s entirel y automat ically. Ho wever, un der certai n circum stances , the applia nce m ay not be a ble to fire th e burner.
59 2. Make s ure therm ostat is cal ling for bur ner oper ation. 3. Check oil suppl y and mak e sure all valves are open. A. DIAGNOSTICS : To ass ist in troubles hootin g this app liance, it is equip ped with an integr ated saf ety and ignit ion contro l with diagn ostics.
60 3. Check the res istance across the cad cel l pins with the cel l covere d (protec ted from exposur e to ambient l ight). T he resistan ce should b e greater th an 2 0,000 ohm s. 4. If cell r esis tances are differ ent from above, r eplace the pl ug - in port ion of cell, (H oneywell Par t No.
