data  plates  from  the  grate  as-

sembly. The data plates contain 

important  warranty  and  safety 

information.

1.  Remove  log  set  assembly  from  carton.

 

Note:

 Do not pick up assembly by logs. This 

could damage heater. Always handle assembly 

by grate.

2.  Remove control cover floor media components.

3.  Remove all protective packaging applied to 

log set for shipment.

3.  Check all items for any shipping damage. If 

damaged, promptly inform dealer where you 

bought heater.

PRODUCT FEATURES

OPERATION

This heater is clean burning. It requires no outside 

venting. There is no heat loss out a vent or up a 

chimney. Heat is generated by realistic flames and 

glowing ceramic logs/coals. This heater is designed 

for vent-free operation with flue damper closed. It has 

been tested and approved to ANSI Z21.11.2 standard 

for unvented heaters. State and local codes in some 

areas prohibit the use of vent-free heaters.

SAFETY PILOT

This heater has a pilot with an Oxygen Deple

-

tion Sensing (ODS) safety shutoff system. The 

ODS/pilot is a required feature for vent-free room 

heaters. The ODS/pilot shuts off the heater if there 

is not enough fresh air.

REMOTE IGNITION AND CONTROL

This gas log set has a battery powered electronic 

remote ignition and control. This system requires 

no matches or other source to light log set.

AIR FOR COMBUSTION 

AND VENTILATION

 WARNING: This heater shall 

not  be  installed  in  a  confined 

space  or  unusually  tight  con-

struction unless provisions are 

provided for adequate combus-

tion and ventilation air. Read the 

following instructions to insure 

proper  fresh  air  for  this  and 

other  fuel-burning  appliances 

in your home. 

Today’s homes are built more energy efficient 

than ever. New materials, increased insulation and 

new construction methods help reduce heat loss 

in homes. Home owners weather strip and caulk 

around windows and doors to keep the cold air out 

and the warm air in. During heating months, home 

owners want their homes as airtight as possible.

While it is good to make your home energy efficient, 

your home needs to breathe. Fresh air must enter 

your home. All fuel-burning appliances need fresh 

air for proper combustion and ventilation.

Exhaust fans, fireplaces, clothes dryers and fuel 

burning appliances draw air from the house to 

operate. You must provide adequate fresh air for 

these appliances. This will insure proper venting 

of vented fuel-burning appliances.

PROVIDING ADEQUATE 
VENTILATION 

The following are excerpts from 

National Fuel 

Gas Code, ANSI Z223.1/NFPA 54, Section 5.3, 

Air for Combustion and Ventilation

.

All spaces in homes fall into one of the three fol

-

lowing ventilation classifications:

1.  Unusually Tight Construction

2.  Unconfined Space

3.  Confined Space

The information on pages 5 through 7 will help you 

classify your space and provide adequate ventilation. 

Unusually Tight Construction

The air that leaks around doors and windows may 

provide enough fresh air for combustion and ven

-

tilation. However, in buildings of unusually tight 

construction, you must provide additional fresh air.
