This  heater  requires  an  electrical  supply  to 
be furnished by the user. The electrical outlet 
should have the following ratings:

120 volts (+/- 10%), 60 Hertz, 15 Amps

Ground Fault Interrupter (GFI)

The heater uses the ground circuit to prove the 

flame by sending a low voltage (40 mV DC) 

signal back to the DSI control. If the ground 
supply is not correctly wired or is missing, the 
heater will not work.

ExTENSION CORDS

Extension cords used to connect the heater 
must  be  3  prong,  grounded  type  of  proper 
gauge. Extension cord requirements are as 
follows:

•  Up to 100 feet (30 m), use 16 AWG rated 

cord

•  101 to 200 feet (32 to 60 m), use 14 AWG 

rated cord.

OPERATION WITH PORTAbLE 
GENERATOR

 WARNING: before operating 

heater  or  any  appliance  from  a 

portable  generator,  verify  that 

generator has been properly con-

nected to earth ground. Improper 

grounding  or  failure  to  ground 

generator  can  result  in  electro-

cution  if  a  ground  fault  occurs. 

Refer to owner’s manual supplied 

by  generator  manufacturer  for 

proper grounding procedures.

The operating voltage range of the heater is 
108  to  132  Volts  (120  Volts  +/-  10%).  Prior 
to plugging heater into generator the output 

voltage  should  be  verified  (if  generator  is 

equipped with the automatic idle feature, the 
output voltage should be measured with the 
generator running at full speed). If the voltage 
does  not  measure  in  this  range  the  heater 
should not be plugged into the generator.

UnPacking

1.  Remove  all  packing  items  applied  to 

heater for shipment. Keep plastic cover 
caps  (attached  to  inlet  connector  and 
hose/regulator assembly) for storage.

2.  Remove all items from carton.
3.  Check all items for shipping damage. If 

heater is damaged, promptly inform dealer 
where you bought heater.
