Placement in Fireplace with a Restrictive Barrier
The following are guidelines for placing a gas log set in a
replace that has a restrictive barrier on the replace for
vented appliance only. See Figure 2.3.
Height of Restriction
(x)
Minimum Depth of
Fireplace/Firebox
No Restriction 14" (356mm)
0" to 3" (76mm) 16" (406mm)
Greater than 3" (76mm) *
*Any barrier greater than 3" placed in front of the gas log set is not
recommended by the manufacturer.
NOTE: Non-combustible material such as refractory brick
may be used to line the oor of the replace in order to raise
the height of the gas log set in relation to a restrictive barrier.
If the unit is raised, the minimum height dimension listed
in the homeowner’s manual must be met or exceeded.
NOTE: If the log set is equipped with a remote receiver, a
restrictive barrier may reduce the battery life by increasing
the ambient temperature inside the replace. Placement of
the receiver outside of the replace will extend the battery
life. (MV models only)
Barriers such as the bottom of a glass door frame
placed in front of a gas log set can change the air
ow characteristics of the replace which in turn
can cause the unit to overheat and malfunction when
installed as a vented log set.

D. Assembly Procedure
1. Center the burner assembly inside the fireplace or
firebox. Make certain that the front of the burner
assembly sits inside the front edge of the replace or
the rebox. Burner assembly should be as far to back
of box as possible.
2.Anchor holes are located on the right and left sides of the
front bracket attached to the engine base. After centering
the burner assembly correctly, mark the holes on the
replace or rebox oor. Drill two (2) 5/32” diameter holes
in the oor of the rebox. Anchor the two anchoring
screws shipped with the unit using Phillips head chuck
and secure the burner assembly to the replace through
the holes drilled earlier.
You must secure the gas log heater to the replace
oor. If not, the entire unit may move when you
adjust the controls. Movement of unit may cause
shifting of the gas logs which leads to sooting and
improper burning. Grate movement could cause a
gas leak.

44 Gas Information
A. Gas Line Connection
NOTICE: A qualied gas appliance installer must connect
the heater to the gas supply. Consult all local codes.
IMPORTANT: Hold heater valve rmly with a wrench to
prevent movement when connecting to inlet pipe.
Always use an external regulator for all propane/LPG
heaters and high pressure one to two-pound systems
only, to reduce the supply tank pressure to a maximum of
13" w.c. This is in addition to the internal regulator in the
heater valve.
The heater gas inlet connection is a 3/8" NPT at the valve.
On all control type units, the inlet connection is on the right
side of unit. To connect from the opposite side, route the
pipe around the back portion of the unit.
When tightening up the joint to the valve, hold the valve
securely to prevent movement.
Test all gas joints from the gas meter to the heater valve for
leaks using a gas analyzer or soap and water solution after
completing connection. DO NOT USE AN OPEN FLAME.
Check the gas pressure with the appliance burning and
the control set to HIGH.
Use new black iron or steel pipe. Internally tinned
copper or copper tubing can be used per National
Fuel Code, section 2.6.3, providing gas meets
hydrogen sulde limits, and where permitted by local
codes. Gas piping system must be sized to provide
minimum inlet pressure (Listed on Data Plate) at the
maximum ow rate (BTU/hr). Undue pressure loss
will occur if the pipe is too small.
A manual shutoff valve must be installed upstream
of the appliance. Union tee and plugged 1/8" NPT
pressure tapping point should be installed upstream
of the appliance.
WARNING
Connecting directly to an unregulated propane/
LPG tank can cause an explosion.
WARNING
CHECK GAS TYPE: The gas supply must be the
same as stated on the heater’s rating plate. If the
gas supply is different, DO NOT INSTALL THE
HEATER. Contact your dealer for the correct model.
