NOTE: To determine the size of the branch gas line from the main gas line to the fireplace, enter the tables below (for iron
pipe or copper tubing) using the distance from the gas meter or second stage regulator to the furthest appliance on the
gas system. Select a pipe or tube diameter which has enough capacity to meet the maximum input requirement of the
fireplace. Regardless, do not use less than 1/2" diameter for the branch line. For any distances required longer than
shown in these tables, refer to the National Fuel Gas Code.
NOTE: There may be a local gas utility requirement specifying a minimum diameter for gas piping. All units require a 1/2 inch pipe
connection at the gas valve.

WARNING: Use only internally tinned copper tubing. If correct copper tubing is not used, tubing can deteriorate and
develop gas leaks.
•
Position the top log so the hole on the bottom fits
over the peg on top of the rear log. The top log is
positioned correctly when it extends over the portion
of the burner that has a single row of ports (holes).
If the top log extends over a slotted row of ports, it is
not in the correct positon.
CAUTION: Proper log location is critical for
trouble-free operation. Ensure that the front and
back log are centered in the grate and are vertical
as seen from the side. There must be no impinge-
ment of the flames from the burner on any log.
Decorative Volcanic Ash
The volcanic ash provided should be sprinkled on the
hearth pan and up to the front burner shield. Do not
sprinkle volcanic ash around or on the burner or logs.
WARNING: Failure to position the parts in accor-
dance with this diagram or failure to use only
parts specifically approved with this heater may
result in property damage or personal injury. Do
not alter logs!
