INSTALLATION

ASSEMBLY PROCEDURE:

1. Center the gas log unit in the fireplace or firebox. Make
certain the front feet of the grate sit inside the front edge
of the fireplace or firebox.
. Anchor holes are located on the right and left sides of
the unit. After centering the grate correctly, mark the
hole positions on the fireplace/firebox floor. Drill two ()
B\cx" diameter holes approximately 1Z\x" deep.
3. Anchor the grate to the fireplace/firebox floor using the
screws provided. Figure 14
Proper installation of the grate is essential to prevent
any movement of the gas logs and controls during

CONNECT THE GAS
NOTICE: A qualified gas appliance installer must connect
the heater to the gas supply. Consult all local codes.
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 sulfide
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 flow 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. Figure 15

CHECk GAS TYPE: The gas supply must
be the same as stated on the heater's rat- gas connect
ing plate. If the gas supply is different, DO
NOT INSTALL THE HEATER. Contact your
dealer for the correct model.
Connecting directly to an unregulated pro-
pane/LPG tank can cause an explosion.
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.
