Cleaning Glass

Clean  glass  with  any  commercial  glass 
cleaner or soap and water. Do not use any 
abrasive material to clean the glass. Do not 
clean glass with any cool water if glass is still 
hot from fire and smoke.
A gas line or gas log lighter may be installed 
for the purpose of installing a vented or vent-
free decorative gas appliance incorporating an 
automatic shutoff device and complying with 
the S

tandard for Decorative Gas Appliances 

for  Installation  in  Vented  Fireplaces, ANSI 
Z21.60

  or 

American  Gas Association  draft 

requirements for Gas Fired Log Lighters for 
Wood Burning Fireplaces, Draft NO. 4

 dated 

August, 1993.
If you wish to install an unvented (vent-free) 
gas log set, only unvented gas log sets which 
have been found to comply with the standard 
for unvented room heaters, ANSI Z21.11.2 are 
to be installed in this fireplace.

  WARNING:  When  using 

a  decorative  vented  gas  log, 

damper  must  be  removed  or 

permanently locked in fully open 

position and glass doors must 

be in fully open position.

GLASS DOORS

Glass doors are optional with this fireplace. 
When fireplace is in operation, doors must be 
fully opened or fully closed position only or a 
fire hazard may be created (see Figure 23).
A fireplace equipped with glass doors oper

-

ates much differently than a fireplace with an 
open front. A fireplace with glass doors has a 
limited amount of air for combustion. Exces

-

sive heat within fireplace can result if too large 
a fire is built or if combustion air gate is not 
completely open.
The following tips should be used to assure 
that  both  fireplace  and  glass  door  retain 
their beauty and function properly. Both the 
flue  damper  and  glass  doors  must  be  fully 
opened before starting a fire. This will provide 
sufficient  combustion  air  and  maintain  safe 
temperatures in firebox.

IMPORTANT:

  The  glass  must  be  allowed 

to warm slowly and evenly. Tempered glass 
will withstand a gradual temperature rise to 
550° F, which is more than a normal fire will 
generate. Such materials as pitch/wax laden 
logs,  very  dry  mill  end  lumber  and  large 
amounts  of  paper  or  cardboard  boxes  can 
create an excessively hot fire and should not 
be burned in this fireplace. Always keep fire 
back  from doors  and  never  allow  flames  to 
contact glass.

  WARNING:  Fireplaces 

equipped  with  glass  doors 

should  be  operated  only  with 

doors fully opened or doors fully 

closed. Doors, if left partly open, 

may draw gas and flame out of 

the  fireplace  opening  creating 

risks of both fire and smoke.
