PLACEMENT OF APPLIANCE

Center the appliance in the fireplace. Make certain 

the grate front feet sit inside the front edge of 

the fireplace and that there is adequate clearance 

around the appliance for access and operation.

CONNECTING TO GAS SUPPLY

 WARNING: A qualified service 

person must connect heater to gas 

supply. Follow all local codes.

Installation Items Needed

Before installing heater, make sure you have the 

items listed below.
•  external regulator (propane/LP models only)
•  piping (check local codes)
•  sealant (resistant to propane/LP gas)
•  equipment shutoff valve
•  test gauge connection
•  sediment trap
•  tee joint
•  pipe wrench
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 3. Pointing the vent down protects 

it from freezing rain or sleet.

  WARNING:  Connecting 

directly to an unregulated pro-

pane/LP  tank  may  cause  an 

explosion.

VENTING SPECIFICATIONS FOR 
INSTALLATION

The fireplace chimney flue and vent must be draft-

ing 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 

obstruction until proper venting is achieved.
The chimney flue damper must be fixed open to 

provide a minimum of 29 square inch flue opein-

ing at all times during operation of the log set. A 

damper clamp can be used to secure the damper 

(see Accessories, page 18). See the 

National Fuel 

Gas Code ANSI Z223.1/NFPA 54, Section 6.6 

for 

details about minimum flue size.

INSTALLING DAMPER CLAMP

Secure the damper stop clam to the edge of the 

damper as shown in Figure 2. If for any reason this 

clamp doesn't work on your fireplace, another suit-

able clamp or permanent stop must be iinstalled, or 

the damper blade must be cut or removed.
