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.

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 

located on floor or wall of fire

-

place. 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 12

•  in a recreational vehicle

•  where  curtains,  furniture, 

clothing  or  other  flammable 

objects are less than 42" from

•  in high traffic areas

•  in windy or drafty areas

Figure 3 - Ventilation Air from Outdoors

ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or 

ducts. You must provide two permanent openings: 

one within 12" of the ceiling and one within 12" 

of the floor. Connect these items directly to the 

outdoors or spaces open to the outdoors. These 

spaces include attics and crawl spaces. Follow the 

National Fuel Gas Code, ANSI Z223.1/NFPA 54, 

Section 5.3, Air for Combustion and Ventilation

 for 

required size of ventilation grills or ducts. 

IMPORTANT:

 Do not provide openings for inlet 

or outlet air into attic if attic has a thermostat-

controlled power vent. Heated air entering the attic 

will activate the power vent.
