If Installed at Floor Level

NOTICE:  Surface  temperatures 

of adjacent walls and mantels be-

come hot during operation. Walls 

and  mantels  above  the  firebox 

may  become  hot  to  the  touch. 

If installed properly, these tem-

peratures meet the requirement 

of the national product standard. 

Follow all minimum clearances 

shown in this manual.

NOTICE: If your installation does 

not  meet  the  minimum  clear-

ances shown, you must do one 

of the following:

•  raise the mantel to an accept-

able height

•  remove the mantel

FLOOR CLEARANCES

A.  If  installing  appliance  on  the  floor  level, 

you must maintain the minimum distance 

of 14" to combustibles (see Figure 8).

B.  If combustible materials are less than 14" 

to the fireplace, you must install appliance 
at least 5" above the combustible flooring 

(see Figure 9).

INSTALLING DAMPER CLAMP 
ACCESSORY FOR VENTED 
OPERATION

Note:  When  used  as  a  vented  heater,  ap-
pliance must be installed only in a solid-fuel 
burning  fireplace  with  a  working  flue  and 
constructed of noncombustible material.

For Massachusetts Residents Only:

 Instal-

lation of this gas log set as a vented appliance 

in the Commonwealth of Massachusetts re

-

quires the damper be permanently removed 

or welded in the fully open position.
If your heater is a manually-controlled model, 

you may use this heater as a vented product. 
There  are  three  reasons  for  operating  your 
heater in the vented mode.

1.  The fireplace does not meet the clearance 

to  combustibles  requirements  for  vent-
free operation.

2.  State or local codes do not permit vent-

free operation.

3.  You prefer vented operation.
If reasons number 1 or 2 above apply to you, 
you  must  permanently  open  chimney  flue 
damper. You must install the damper clamp 
accessory (to order, see 

Accessories

, page 

27).  This  will  insure  vented  operation  (see 
Figure 10, page 12). The damper clamp will 

keep  damper  open.  Installation  instructions 

are included with clamp accessory.
