Lo-Rider Vent Free Fireboxes

IMPORTANT SAFETY INFORMATION

1.  Due  to  high  temperatures,  the  firebox  should  be 

located out of traffic and away from furniture and 

draperies.

.  Children and adults should be alerted to the hazard 

of high surface temperature and should stay away 

to avoid burns or clothing ignition.

3.  Young children should be carefully supervised when 

they are in the same room with the firebox.

4.  Do not place clothing or other flammable material 

near the fireplace when the firebox is in use.

5.  Any safety screen or guard removed for servicing, 

must be replaced prior to operating a heater within 

the firebox. 

6.  Installation and repair should be done by a qualified 

service person.

7.   To prevent malfunction and/or sooting, an unvented 

gas heater/firebox should be cleaned at least annu-

ally by a professional service person. More frequent 

cleaning may be required due to excessive lint from 

carpeting, etc. It is imperative that control compart-

ments, burners and circulating air passageways be 

kept clean.

8.  The installation must conform with local codes or, in 

the absence of local codes, with the National Fuel Gas 

Code, ANSI Z3.l/NFPA 54. 

9.  This unit complies with ANSI Z21.91 Ventless Fire-

box Enclosures for gas-fired unvented decorative 

room heaters. 

10. Do not install the unvented heater in a bathroom.
11.  Do not install the unvented heater in a bedroom unless 

the  maximum  input  rating  is  equal  to  or  less  than 

10,000 Btu/hr.

1. Avoid any drafts that alter burner flame patterns. Do not 

allow fans to blow directly into fireplace. Do not place 

a blower inside burn area of firebox. Ceiling fans may 

create drafts that alter burner flame patterns. Sooting 

and improper burning will occur.

13. 

CAUTION:

 Candles, incense, oil lamps, etc. produce 

combustion byproducts including soot. Vent-free appli-

ances will not filter or clean soot produced by these 

types of products. In addition, the smoke and/or aro-

matics (scents) may be reburnt in the vent-free appli-

ance which can produce odors. It is recommended to 

minimize the use of candles, incense, etc. while the 

vent-free appliance is in operation. 

14. Keep  room  area  clear  and  free  from  combustible 

materials, gasoline and other flammable vapors and 

liquids.

15. During manufacturing, fabricating and shipping, various 

components of this appliance are treated with certain 

oils, films or bonding agents. These chemicals are not 

harmful but may produce annoying smoke and smells 

as they are burned off during the initial operation of the 

appliance; possibly causing headaches or eye or lung 

irritation. This is a normal and temporary occurrence.

 

The  initial  break-in  operation  should  last  -3  hours 

with the burner at the highest setting. Provide maxi-

mum ventilation by opening windows or doors to allow 

odors to dissipate. Any odors remaining after this initial 

break-in period will be slight and will disappear with 

continued use.

 16. Always  have  a  fireplace  screen  in  place  when  the 

appliance is in operation and, unless other provisions 

for combustion air are provided, the screen shall have 

an opening(s) for induction of combustion air.

ARNING

  Improper installation or use of the heater can cause serious injury or death from 

fire, burns, explosion or carbon monoxide poisoning.

  Do not allow fans to blow directly into the fireplace. Avoid any drafts that alter 

burner flame patterns.

  Do  not  use  a  blower  insert,  heat  exchanger  insert  or  other  accessory,  not 

approved for use with this heater where applicable.
