SPECIAL PRECAUTIONS / SI (METRIC) CONVERSION FACTORS 
 CAUTION
18. The unit should be isolated from the gas supply piping 
  system by closing its field installed manual shut-off valve. 
  This manual shut-off valve should be located within 6' of 
  the heater.
19. Turn off all gas before installing appliance.
20. Ensure that the supply voltage to the appliance, as 
  indicated on the serial plate, is not 5% less than the rated  
 voltage.
21. Check the gas inlet pressure at the unit upstream of the   
  combination gas control. The inlet pressure should be 
  6-7" W.C. on natural gas or 11-14" W.C. on propane. If   
  inlet pressure is too high, install an additional pressure  
  regulator upstream of the combination gas control.
22. Service or repair of this equipment must be performed by 
  a qualified service agency.
23. Do not attempt to reuse any mechanical or electronic 
  ignition controllers which has been wet. Replace defective  
 controller.
IMPORTANT
1. To prevent premature heat exchanger failure, do not locate 
ANY gas-fired appliances in areas where corrosive vapors 
(i.e. chlorinated, halogenated or acid) are present in the   
atmosphere.
2. To prevent premature heat exchanger failure, the input to   
the appliance as indicated on the serial plate, must not   
exceed the rated input by more then 5%.
3. To prevent premature heat exchanger failure, observe 
heat exchanger tubes. If the tubes become red while 
blower and furnace are in operation, check to be sure the 
blower has been set to the proper rpm for the application. 
Refer to page 15 for blower adjustments.
4. Start-up and adjustment procedures must be performed 
by a qualified service agency.
