Natural and Propane/LP Gas: 

Natural and pro

-

pane/LP gases are fuel gases. Fuel gases are 
odorless. An odor-making  agent is added  to 
fuel gases. The odor helps you detect a fuel 
gas  leak.  However,  the  odor  added  to  fuel 
gas can fade. Fuel gas may be present even 
though no odor exists.
Make  certain  you  read  and  understand  all 
warnings. Keep this manual for reference. It 
is your guide to safe and proper operation of 
this heater.

  WARNING:  Any  change  to 

this  heater  or  its  controls  can 

be dangerous.

  WARNING:  Do  not  use  a 

blower  insert,  heat  exchanger 

insert or other accessory not ap-

proved for use with this heater.

Due  to  high  temperatures,  the 

appliance should be located out 

of traffic and away from furniture 

and draperies.

Do not place clothing or other 

flammable  material  on  or  near 

the appliance. Never place any 

objects on the heater.

Surface of heater becomes very 

hot when running heater. Keep 

children and adults away from 

hot  surface  to  avoid  burns  or 

clothing  ignition.  Heater  will 

remain hot for a time after shut-

down.  Allow  surface  to  cool 

before touching.

Carefully supervise young chil-

dren when they are in the same 

room with heater.

Make sure grill guard is in place 

before running heater.

Keep  the  appliance  area  clear 

and free from combustible ma-

terials, gasoline and other flam-

mable vapors and liquids.

1.  This appliance is only for use with the type 

of gas indicated on the rating plate. This 
appliance  is  not  convertible  for  use  with 
other gases.

2.  Do not place propane/LP supply tank(s) 

inside any structure. Locate propane/LP 
supply tank(s) outdoors.

3.  This  heater  shall  not  be  installed  in  a 

bedroom or bathroom.

4.  If you smell gas

• shut off gas supply

• do not try to light any appliance

• do not touch any electrical switch; do not 

use any phone in your building

• immediately call your gas supplier from 

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

• if  you  cannot  reach  your  gas  supplier, 

call the fire department

5.  This heater needs fresh, outside air ventila

-

tion to run properly. This heater has an Oxy

-

gen Depletion Sensing (ODS) safety shutoff 
system. The ODS shuts down the heater if 
not enough fresh air is available. See 

Air for 

Combustion and Ventilation,

 page 5.

6.  Keep all air openings in front and bottom 

of heater clear and free of debris. This will 
insure enough air for proper combustion.

7.  If heater shuts off, do not relight until you 

provide fresh, outside air. If heater keeps 
shutting off, have it serviced.

8.  Do not run heater

• where flammable liquids or vapors are 

used or stored

• under dusty conditions

9.  Before using furniture polish, wax, carpet 

cleaner or similar products, turn heater off. If 
heated, the vapors from these products may 
create a white powder residue within burner 
box or on adjacent walls or furniture.

10. Do not use heater if any part has been 

under water. Immediately call a qualified 
service  technician  to  inspect  the  room 

heater  and  to  replace  any  part  of  the 

control system and any gas control which 
has been under water.

11. Turn off and let cool before servicing. Only 

a qualified service person should service 
and repair heater.
