Never  use  a  gas  container,  LPG  connector 
hose, LPG cylinder or any other fuel item that 
is damaged or appears damaged.

The LPG cylinder valve should be fully closed 
when the generator is not in use or is running 
with gasoline.


The regulator/hose assembly and cylinder 
valve must be inspected before each use for 
leaks or sign of damages.

Use  only  20  or  30  lb  capacity  cylinders  with 
Type  1,  right  hand  Acme  threads  with  this 
generator.  Verify  the  re-qualification  date 
on the tank has not expired. Do not use rusted 
or damaged cylinders. 

All new cylinders must be purged of air and 
moisture prior to filling. Used cylinders that 
have not been plugged or kept closed must 
also be purged. The purging process should 
be done by your propane gas supplier.

Do not connect or disconnect the LPG cylinder 
in enclosed area.

Do not install or replace the LPG cylinder near 
open flames, pilot lights, or sparking electrical 
equipment such as power tools, welders and 
grinders.

Attach  the  LPG  regulator/hose  assembly 
(included)  to  the  LPG  hose  connector  (inlet) 
on the control panel of the generator. Tighten 
the nut with 19 mm or adjustable wrench.
Remove the safety plug or cap from the 
cylinder valve.
Attach the other end of the LPG regulator/hose 
assembly to the cylinder valve. Tighten the nut
by  hand  clockwise  to  a  positive  stop.  Do  not 
use  a  wrench  to  tighten.  Use  of  wrench  may 
damage quick closing coupling nut and result 
in a hazardous condition.
Do not use tape or any type sealant to seal the 
LPG hose connections.

Always  position  the  cylinder  so  the  connection 
between the valve and the regulator won’t cause 
bends or kinks in the hose.
Spray  a  soapy  water  solution  (one  part  liquid 
detergent  and  one  part  water)  to  check  all 
connections  for  leaks  before  attempting  to 
use generator.   Slowly open the cylinder valve. 
A  leak  exists  if  bubbles  appear  or  grow  larger 
in size or number. This must be corrected before 
using  the  generator.  Contact  your  local 
Authorized  Service  Facility  for  assistance.  Do 

not attempt to make repairs yourself.
Do not check for leaks with a lighted match or flame.
Do not light or smoke cigarettes.
Check the fuel system periodically for leaks 
or signs of damages. 

LPG under pressure is highly flammable and 
can cause a fire or explosion if ignited.

CAUTION

LPG is heavier than air and can accumulate in confined 
spaces and low places in the event of a leak.
LPG has a distinctive odor to help detect 
potential leaks.

Do not allow children to tamper or play with 
the LPG cylinder.

 If you smell gas: close off the gas supply. Spray 
a soapy water solution to check all connections 
for  leaks  before  attempting  to  use  generator. 
Contact  a  qualified  technician  to  inspect  and 
repair  the  LPG  system  if  a  leak  found  before 
using the generator.

You must use the supplied regulator/hose 
assembly for safe operation.

WARNING

Device  used  for  handling  LPG  must  be  installed 
and  used  in  strict  conformance  with  NFPA  58 
(Liquefied  Petroleum  Gas  Code)  and  NFPA  54 
(National Fuel Gas) and all other codes, regulations 
and manufacturer recommendations.

If you smell gas: close off the gas supply. Make 
sure there is no leak before using the generator.


Do not check for leaks with a lighted match or 
flame.
The LPG cylinder valve should be fully closed 
when the generator is not in use or is running 
with gasoline.
