INSTALLATION

IMPORTANT:

 Vent-free heaters add moisture 

to the air. Although this is beneficial, installing 

heater in rooms without enough ventilation air 

may cause mildew to form too much moisture. 

See 

Air for Combustion and Ventilation

, pages 

6 through 8.
Before  beginning  assembly  or  operation  of 

the  product,  make  sure  all  parts  are  pres-

ent.  Compare  parts  with  package  contents 

list.  If  any  part  is  missing  or  damaged,  do 

not  attempt  to  assemble,  install  or  operate 

the  product.  Contact  customer  service  for 

replacement parts.
Before installing heater, make sure you have 

the items listed below:
•  Hardware package (provided with heater)

CHECK GAS TYPE

Be sure your gas supply is right for your heat-

er. Otherwise, call dealer where you bought 

the heater for proper type heater.
