B.  ADJUSTMENTS

7 DAYS AFTER INSTALLATION and EVERY 6 MONTHS THEREAFTER

Inspect bolts, nuts, screws, (bearing set screws), non-permanent gas connections (unions, shut-off valves,

orifices, and grounding connections).  Motor and drive belts 

should be

 examined.  Cracked or seriously

frayed belts 

should be

 replaced.  Tighten loose V-belts when necessary.  Complete operational check of

controls and valves.  Complete operational check of 

ALL

 safety devices (door switches, lint drawer

switch, sail switch, burner and hi-limit thermostats).
