FOR YOUR SAFETY 

Do  not  store  or  use  gasoline  or  other 
flammable vapors and liquids in the vicinity of 
this or any other appliance. 
 

 

WARNING: 

If  the  information  in  this  manual  is  not 
followed  exactly,  a  fire  or  explosion  may 
result,  causing  property  damage,  personal 
injury, or loss of life. 
 

 

WHAT TO DO IF YOU SMELL GAS 

 

1.  Open a window. 
2.  Do not try to light any appliance. 
3.  Do not touch any electrical switch; do not 

use the phone in your building. 

4.  Immediately call your gas supplier from a 

neighbor’s  phone.    Follow  the  gas 
supplier’s instructions. 

5.  If you cannot reach your gas supplier, call 

the fire department. 
 

 

 

IMPORTANT: 

Installation and service must 

be  performed  by  a  qualified  professional 
installer, service agency, or the gas supplier. 
 

 

NOTE: 

This appliance is only for use with the 

type of gas indicated on the rating plate. 
 

 

Solid-fuels shall not be burned in a fireplace 
where a decorative appliance is installed. 
 

 

 

This  Hargrove  vented  gas  log  set  is  to  be 
installed  only  in  a  solid-fuel  burning fireplace 
with  a  working  flue  and  constructed  of 
noncombustible  material.    The  installation, 
including  provisions  for  combustion  and 
ventilation  air  must  conform  to  the 

National 

Fuel Gas Code, ANSI Z223.1/NFPA 54, or the 
CSA  B149.1,  Natural  Gas  and  Propane 
Installation Code

, and applicable local building 

code. A damper clamp is included to maintain 
the minimum permanent vent opening and to 
prevent full closure of the damper blade. The 
gas log set must be burned with the 

damper 

completely open (In the Commonwealth of 
Massachusetts the damper must either be 
welded  in  the  fully  open  position  or 
completely  removed)

  and  the  chimney  free 

of any obstructions or restrictions. 
 
The  realistic  yellow  flame  produces  carbon 
monoxide and soot.  Under normal conditions, 
these products are exhausted up the chimney.  
If  fumes  or  soot,  from  the  gas  burning,  are 
evident  in the room when the damper is fully 
open  it  indicates  that  the  fireplace  draft  is 
defective.    Do  not  operate  your  gas  log  set 
until  the  fireplace  draft  is  corrected. 

It  is  the 

home-owners responsibility to assure their 
fireplace has adequate draft.
