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.
2. Refer to Figure 4 for hole locations. After centering
the grate correctly, mark the hole positions on the fire-
place/firebox floor. Drill two (2) 5/32" diameter holes
approximately 1Z\x" deep.
3. Anchor the grate to the fireplace/firebox floor using the
screws provided. Figure 4
Proper installation of the grate is essential to prevent any
movement of the gas logs and controls during operation.

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 5

Gas Connection
Hold appliance regulator firmly with a wrench
to prevent movement when connecting to inlet piping.
The gas supply must be the same as
stated on the gas logs rating plate. If the gas supply is dif-
ferent, Contact your
dealer for the correct model.
Always use an external regulator for all propane/LPG gas
logs only, to reduce the supply tank pressure to a maximum
of 13" w.c. This is in addition to the regulator fitted to the
gas log set. High pressure natural gas systems require a
regulator to reduce supply pressure to 10" w.c.
