CONNECTING FIREPLACE TO GAS

Installation Items Needed

•  Phillips screwdriver 
•  sealant (resistant to propane/LP gas, not 

provided)

1.  Remove screws that attach branch sup

-

port to fireplace (see Figure 23). Carefully 

lift  up  branch  support  and  remove  from 

fireplace (see Figure 23).

NOTICE:  Most  building  codes 

do  not  permit  concealed  gas 

connections. A flexible gas line 

is provided to allow accessibility 

from the fireplace (see Figure 23). 

The flexible gas supply line con

-

nection to the equipment shutoff 

valve should be accessible.

Branch Support

We  recommend  that  you  install  a  sediment 

trap in supply line as shown in Figure 22. Lo

-

cate sediment trap where it is within reach for 
cleaning. Install in piping system between fuel 
supply and heater. Locate sediment trap where 
trapped matter is not likely to freeze. A sediment 

trap  traps  moisture  and  contaminants.  This 

keeps them from going into fireplace controls. 

If sediment trap is not installed or is installed 

wrong, fireplace may not run properly.

2. 

Route  flexible  gas  line,  included,  from 

fireplace  control  to  equipment  shutoff 
valve through side or rear access holes 
in outer casing.

3.  Apply  pipe  joint  sealant  lightly  to  male 

threads  of  gas  connector  attached  to 

flexible gas line/equipment shutoff valve 

(see Figure 24).

 CAUTION: Avoid damage to 

gas  control.  Hold  gas  control 

with wrench when connecting it 

to gas piping and/or fittings.

4.  Check all gas connections for leaks. See 

Checking Gas Connections, 

page 19.

5.  Replace branch support back into fireplace. 

Feed flexible gas line into fireplace base area 
while replacing branch support. Make sure 
the entire flexible gas line is in fireplace base 
area. Reattach branch support to fireplace 
with screws removed in step 1.
