INSTALLATION

NOTICE: This heater is intended 

for  use  as  supplemental  heat. 

Use this heater along with your 

primary heating system. Do not 

install  this  heater  as  your  pri

-

mary heat source. If you have a 

central heating system, you may 

run system’s circulating blower 

while using heater. This will help 

circulate the heat throughout the 

house. In the event of a power 

outage, you can use this heater 

as your primary heat source.

 WARNING: A qualified service 

person must install heater. Fol

-

low all local codes.

NOTICE:  State  or  local  codes 

may only allow operation of this 

appliance in a vented configura

-

tion.  Check  your  state  or  local 

codes.

 WARNING: Before installing 

in a solid fuel burning fireplace, 

the  chimney  flue  and  firebox 

must be cleaned of soot, creo

-

sote, ashes and loose paint by 

a  qualified  chimney  cleaner. 

Creosote  will  ignite  if  highly 

heated. A dirty chimney flue and 

firebox may create and distribute 

soot within the house. Inspect 

chimney  flue  for  damage.  If 

damaged,  repair  flue  before 

operating heater.

 WARNING: Seal any fresh air 

vents or ash clean-out doors lo-

cated on floor or wall of fireplace. 

If not, drafting may cause pilot 

outage or sooting. Use a heat-

resistant  sealant.  Do  not  seal 

chimney flue damper. 

 WARNING: Never install the 

heater

•  in  a  bedroom  or  bathroom 

unless  installed  as  a  vented 

appliance, see page 11

•  in a recreational vehicle

•  where  curtains,  furniture, 

clothing  or  other  flammable 

objects are less than 42" from 

the front, top or sides of the 

heater

•  in high traffic areas

•  in windy or drafty areas

  CAUTION:  This  heater  cre-

ates  warm  air  currents.  These 

currents move heat to wall sur-

faces  next  to  heater.  Installing 

heater next to vinyl or cloth wall 

coverings  or  operating  heater 

where impurities (such as, but 

not limited to, tobacco smoke, 

aromatic candles, cleaning flu

-

ids, oil or kerosene lamps, etc.) in 

the air exist, may discolor walls 

or cause odors.

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 from too much moisture. See Air 

for Combustion and Ventilation

, page 5.

CHECK GAS TYPE

Use the correct gas type (natural or propane/LP) 

for your unit. If your gas supply is not correct, do 

not install log set. Call dealer where you bought 

log set for proper type fireplace. 

  WARNING:  This  appliance 

is equipped for natural or pro

-

pane/LP gas. Field conversion 

is not permitted.
