DRL6500 Linear Direct-Vent Gas Fireplaces
Proper Sizing of Gas Line
Properly size and route the gas supply line from the supply regulator to the area where the appliance is to be installed
per requirements outlined in the National Fuel Gas Code, NFPA 54—latest edition (USA) or CAN/CGA-B149.1—latest
edition (Canada).
NOTE:
•
All fireplaces are factory-equipped with a flexible gas line connector and 1/2" shutoff valve (Figure 33, Page 40).
•
See Massachusetts Horizontal Vent Requirements for additional requirements for installations in the state of
Massachusetts in the USA.
•
A pipe joint compound rated for gas should be used on the threaded joints. Ensure propane-resistant compounds
are used in propane applications. Be very careful that the pipe compound does not get inside the pipe.
•
A sediment trap in the supply line as close as possible to the fireplace is recommended.
•
Check with the local building official for local code requirements (e.g., Are below grade penetrations of the gas
line allowed?, etc).
If propane is used, be aware that with a tank that is too small (i.e., under 100 lbs, if this
is the only gas appliance in the dwelling—see NPFA 58), there may be a loss of pressure.
This can result in insufficient fuel delivery that can cause sooting, delayed ignition, or other
malfunctions. Any damage resulting from an improper installation is not covered by the
limited warranty.
Rough in the Electrical Supply, if Needed
4.
1. As necessary, rough in the fireplace electrical supply per NEC and local codes.
Place the Fireplace in the Framing, Secure, and install Heat Shield
5.
1. See instructions on Page 44.
VENT SYSTEM PREPARATION
Select a Horizontal or Vertical Vent System
6.
1. With the fireplace secured in the framing, determine the vent route and identify the exterior termination location.
The following sections describe vertical (roof) and horizontal (exterior wall) vent applications. Use only approved
vent components (Page 9 and Page 48).
NOTE: This fireplace must be vented directly to the outside.
The vent system may not service multiple appliances, and must never be connected to a flue
serving a separate solid fuel burning appliance.
NOTE: The vent pipe is tested to be run inside an enclosed wall (such as a chase). There is no requirement for
inspection openings in the enclosing wall at any of the joints in the vent pipe.
Install the Vent Restrictor (if necessary)
7.
1. Use the vent run descriptions in Figure 12 to determine if a vent restrictor is necessary.
2. If necessary, assemble the vent restrictor and wings as detailed in Figure 13 and Figure 14.
3. If necessary, install the appropriate vent restrictor with the flaps facing up (Figure 13). The vent restrictor is held in
place by friction. The vent restrictor must not be visible inside the firebox.
NOTE: If the baffle and back panel are installed, remove them before installing the vent restrictor.
NOTE: The vent restrictor is shipped in the firebox.
