CONNECTING TO GAS SUPPLY

 WARNING: A qualified ser

-

vice  person  must  connect  log 

set  to  gas  supply.  Follow  all 

local codes.

Installation Items Needed

Before installing log set, make sure you have 
the items listed below.
•  piping (check local codes)
•  sealant (resistant to Propane/LP gas)
•  equipment shutoff valve
•  test gauge connection
•  adjustable (crescent) wrench or pliers
•  sediment trap
•  tee joint
•  pipe wrench

  CAUTION:  Use  only  new, 

black  iron  or  steel  pipe.  Inter

-

nally-tinned copper tubing may 

be used in certain areas. Check 

your  local  codes.  Use  pipe  of 

1/2" diameter or greater to allow 

proper gas volume to log set. If 

pipe is too small, undue loss of 

volume will occur.

Installation must include a equipment shutoff 
valve, union, and plugged 1/8" NPT tap. Locate 
NPT tap within reach for test gauge hook up. 
NPT tap must be upstream from log set (see 
Figure 4, page 7).

IMPORTANT:

 Install equipment shutoff valve 

in  an  accessible  location.  The  equipment 
shutoff valve is for turning on or shutting off 
the gas to the appliance.
Apply pipe joint sealant lightly to male NPT 
threads. This will prevent excess sealant from 
going into pipe. Excess sealant in pipe could 
result in a clogged burner injector.

  WARNING:  Use  pipe  joint 

sealant that is resistant to liquid 

petroleum (LP) gas. 

VENTING SPECIFICATIONS FOR 
INSTALLATION

The fireplace chimney flue and vent must be 
drafting properly. To check the vent for proper 
drafting: Light a tightly rolled newspaper on 

one end and place it at the inside front edge 

of the fireplace. Observe the smoke and be 
sure  the  vent  is  properly  drawing  it  up  the 
chimney. If the smoke spills out into the room, 
extinguish the flame and remove any obstruc

-

tion until proper venting is achieved.
The chimney flue must remain open a mini

-

mum of 3" at all times during the operation 
of this log set. 

For Massachusetts Residents Only

Installation of this vented gas log set in the 
Commonwealth  of  Massachusetts  requires 
the  damper  be  permanently  removed  or 
welded in the fully open position.

INSTALLING DAMPER CLAMP

Secure  the  damper  stop  clamp  provided  to 
the leading edge of the damper as shown in 
Figure 3. If for any reason this clamp doesn't 
work on your fireplace, another suitable clamp 
or permanent stop must be installed, or the 
damper blade must be cut or removed.
