INSTALLATION

Continued 

Note:

  Install optional  GHRCTB Receiver  and 

Hand-Held Remote Control Kit (see 

Accessories

page 26) before installing gas log heater. See in-

stallation instructions included with the kit. 
1.  Apply  pipe  joint  sealant  lightly  to  male 

threads of gas fitting (not provided). Connect 

approved flexible gas hose to inlet side of gas 

control (see Figure 11).

2.  Position heater assembly in fireplace. 
3.  Connect to gas supply. See 

Connecting To 

Gas Supply

.

(if allowed by local 
codes) 

CONNECTING TO GAS SUPPLY

  WARNING:  This  appliance 

requires  a  3/8"  NPT  (National 

Pipe Thread) inlet connection to 

the pressure regulator.

 WARNING: A qualified service 

person must connect heater to gas 

supply. Follow all local codes.

  CAUTION:  Never  connect 

propane/LP  fireplace    directly 

to the propane/LP supply. This 

heater requires an external regu-

lator  (not  supplied).  Install  the 

external regulator between the 

heater and propane/LP supply.

 WARNING: Never connect 

natural gas fireplace to private 

(non-utility)  gas  wells.  This 

gas  is  commonly  known  as 

wellhead gas.

Installation Items Needed

Before installing heater, make sure you have the 

items listed below.
•  external regulator (supplied by installer)
•  piping (check local codes)
•  sealant (resistant to propane/LP gas)
•  equipment shutoff valve *
•  test gauge connection *
•  sediment trap
•  tee joint
•  pipe wrench
•  approved flexible gas line with gas connector 

(if allowed by local codes) (provided) 

* A CSA design-certified equipment shutoff valve 

with 1/8" NPT tap is an acceptable alternative to 

test gauge connection. Purchase the optional CSA 

design-certified equipment shutoff valve from your 

dealer. See 

Accessories

, page 26.

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 inches 

of water. If you do not reduce incoming gas pres-

sure, heater regulator damage could occur. Install 

external regulator with the vent pointing down 

as shown in Figure 12. Pointing the vent down 

protects it from freezing rain or sleet.

  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 heater. If 

pipe is too small, undue loss of 

volume will occur.
