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. | |

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:Aqualifiedservice personmustconnectheatertogas 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.
