INSTALLING HEATER BASE 
ASSEMBLY

 WARNING: You must secure 

this heater to fireplace floor. If 

not, heater will move when you 

adjust controls. Moving heater 

may  cause  a  gas  leak  or  log 

misplacement.

  WARNING:  If  installing  in  a 

sunken  fireplace,  special  care 

is  needed.  You  must  raise  the 

fireplace  floor  to  allow  access 

to  heater  control  panel.  This 

will  insure  adequate  air  flow 

and guard against sooting and 

controls being damaged. Raise 

fireplace floor with noncombus

-

tible material. Make sure material 

is secure.

  CAUTION:  Do  not  pick  up 

heater base assembly by burn

-

ers. This could damage heater. 

Only handle base assembly by 

grates.

IMPORTANT: 

Make sure the heater burners are 

level. If heater is not level, heater will not work 

properly. For thermostat models, avoid damage 

to thermostat bulb. Avoid nicks or sharp bends 

in thermostat bulb wire. Keep thermostat bulb 

in mounting bracket until ready to mount base 

to floor. See 

Optional Positioning Of Thermostat 

Sensing Bulb

, page 25.

Installation Items Needed

•  hardware package (provided with heater)

•  approved flexible gas hose and fittings (not 

provided) (if allowed by local codes) 

• 

sealant  (resistant  to  propane/LP  gas,  not 

provided)

•  electric drill with 3/16" drill bit (metal or ma-

sonry as applicable)

•  flathead screwdriver

•  pipe wrench

INSTALLATION

Continued

Figure 11 - Attaching Flexible Gas Hose 

to Heater Gas Regulator

1.  Apply  pipe  joint  sealant  lightly  to  male 

threads of gas fitting (not provided). Connect 

approved flexible gas hose to gas regulator of 

heater (see Figure 11). 

IMPORTANT:

 Hold 

gas regulator with wrench when connecting 

flexible gas hose.

2.  Locate  two  masonry  screws  in  hardware 

package. 

3.  Place heater base in fireplace.

4.  Place logs in their proper position on heater 

base (see Installing Logs, page 15).

5.  Center heater base and logs front-to-back and 

side-to-side in fireplace.

6.  Carefully remove logs without moving heater 

base.

7.  Mark screw locations through one hole on 

each side of the base (see Figure 12). If install

-

ing in a brick-bottom fireplace, mark screw 

locations in mortar joint of bricks.

8.  Remove heater base from fireplace.
