CONNECTING TO GAS SUPPLY

  WARNING:  This  appliance 

requires a 45° male flare fitting 

5/8"-18  UNF  (Unified  National 

Fine Thread) inlet connection and 

the flexible gas line provided.

  WARNING:  A  qualified 

service  person  must  connect 

fireplace to gas supply. Follow 

all local codes.

 WARNING: Never connect 

natural gas fireplace to private 

(non-utility)  gas  wells.  This 

gas  is  commonly  known  as 

wellhead gas.

IMPORTANT:

 For natural gas, check gas line 

pressure before connecting fireplace to gas 
line.  Gas  line  pressure  must  be  no  greater 
than 14" of water. If gas line pressure is higher, 

heater regulator damage could occur.

  CAUTION:  Never  connect 

propane/LP  fireplace  directly 

to the propane/LP supply. This 

fireplace  requires  an  external 

regulator (not supplied). Install 

the external regulator between 

the  fireplace  and  propane/LP 

supply.

For propane/LP units, the installer must supply 

an external regulator. The external regulator 

will reduce incoming gas pressure. You must 
reduce  incoming  gas  pressure  to  between 
11"  and  14"  of  water.  If  you  do  not  reduce 
incoming  gas  pressure,  fireplace  regulator 

damage could occur. Install external regula-

tor with the vent pointing down as shown in 
Figure 21. Pointing the vent down protects it 
from freezing rain or sleet.

Pointing Down

  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" or greater diameter to allow 

proper gas volume to fireplace. 

If pipe is too small, undue loss 

of volume will occur.

Installation must include an equipment shutoff 

valve, union, and plugged 1/8" NPT tap. Lo

-

cate NPT tap within reach for test gauge hook 

up. NPT tap must be upstream from heater 

(see Figure 22, page 18).

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.
Check  your  building  codes  for  any  special 
requirements for locating equipment shutoff 

valve to fireplaces.
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 clogged fireplace valves.

  WARNING:  Use  pipe  joint 

sealant that is resistant to liquid 

petroleum (LP) gas.
