•  Children and adults should be alerted to the hazard of high 

surface temperature and should stay away to avoid burns or 

clothing ignition.

•  Young children should be carefully supervised when they are 

in the same room with the heater.

•  Do not place clothing or other flammable material on or near 

the heater.

•  Any safety screen or guard removed for servicing the heater 

must be replaced prior to operating the heater.

•  Installation and repair should be done by a qualified service 

person. The heater should be inspected before use and at 

least annually by a professional service person. More fre-

quent cleaning may be required due to excessive lint from 

carpeting, bedding material, etc. It is important that control 

compartments, burners and circulating air passageways of 

the heater be kept clean.

•  Allow the heater to cool before servicing. Always shut off the 

gas to the heater while performing service work. 

 •  The  installation  must  conform  with  local  codes  or,  in  the 

absence  of  local  codes  with  the  National  Fuel  Gas  Code, 

ANSI Z3.1/NFPA 54-latest edition.

•  The heater and its individual shut-off valve must be discon-

nected from the gas supply piping system while performing 

any tests of the gas supply piping system at pressures in 

excess of 1/ psig.

•  The  heater  must  be  isolated  from  the  gas  supply  piping 

system by closing its individual manual shut-off valve during 

any pressure testing of the gas supply piping system at test 

pressures equal to or less than 1/ psig.

•  Keep heater area clear and free from combustible materials, 

gasoline and other flammable vapors and liquids.

•  Do  not  use  this  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.

•  Input ratings are shown in BTU per hour and are for elevations 

up to 4,500 feet. Do not install this heater at an elevation 

above 4,500 feet if the gas supply has not been derated for 

that elevation. Consult your local gas supplier. (For operation 

at elevations above 4,500 feet, equipment ratings shall be 

reduced at the rate of 4 percent for each 1,000 feet above 

4,500 feet before selecting appropriately sized equipment). 

When installing any vent-free appliance at elevations above 

4500 feet, nuisance pilot outages may occur.

•  Ensure that the heater is clean when operating. Excessive 

dust accumulation on the burner will increase the amount 

of  carbon  monoxide  formation  and  could  lead  to  carbon 

monoxide poisoning and/or death.

•  This appliance is intended for supplemental heating. If the 

appliance is used in a room as the sole source of heat, then 

condensation may occur on colder surfaces within the room.

•  Carbon monoxide poisoning – early signs of carbon monox-

ide poisoning resemble the flu with headaches, dizziness, 

or nausea.  If you have these signs, get fresh air at once!  

Turn off the gas supply to the appliance and have the heater 

inspected by a qualified service technician.  Some people 

are more affected by carbon monoxide than others.  These 

include pregnant women, people with heart or lung disease 

or anemia, those under the influence of alcohol, and those 

at high altitudes.

•  Maintain minimum clearances.

•  Do  not  install  the  appliance  in  a  sleeping  room  or  bath-

room.

•  Do not place any objects on top of the appliance.
