Install Log Set
1. Remove the logs from their packaging, and inspect
each piece for damage. DO NOT INSTALL DAM-
AGED LOGS.
2. Install the rear log by placing it on the sheet metal
shelf at the back of the firebox. (Fig. 23) The log
should touch the back wall of the firebox and be
centered.
3. Install the right log by placing it on the sheet metal
bracket behind the grate with the right end of the
log, “the thicker end”, touching the grate and the
right side the firebox. Swing the left end of the log
“painted end”, backward until it comes in contact
with the branch on the rear log. Set the log down
over the bent tab on the right. When the log is in
place it rests on the tab mentioned earlier and the
tip of it comes in contact with the branch on the rear
log. (Fig. 23)

This appliance should only be
connected by a qualified gas techni-
cian. Test to confirm manifold
pressures as specified below.
The UVS27 and its individual shutoff valve must
be disconnected from the gas supply piping
during any pressure testing of that system at test
pressures in excess of 1/2 psig (3.5 kPa).
The UVS27 must be isolated from the gas supply
piping system by closing its individual manual
shutoff valve during any pressure testing of the
gas supply piping system at test pressure equal
to or less than 1/2 psig.
There must be a gas shutoff between the stove
and the supply.
In order to connect Natural Gas, use a fitting with
1/2” NPT on the valve side and 1/2” natural gas
supply line with an input of 28,000 BTUs at a
manifold pressure of 3.5” between minimum inlet
supply of 5.5” w.c. and maximum of 14.0” w.c.
In order to connect Propane, use a fitting with 1/2”
NPT on the valve side and 1/2” propane gas supply
line with an input of 28,000 BTUs at a manifold
pressure of 11.0” between a minimum inlet supply
of 11.0” w.c. and maximum of 14.0” w.c.
CAUTION
4. Install the left log by placing it on the sheet metal
bracket behind the grate with the left end of the log,
“the thicker end” touching the grate and the left end
of the firebox. Lay the log into the recessed area on
the left branch of the rear log. When the log is in
place, it will rest on the left branch of the rear log
toward the left side of the branch.
5. Loosely sprinkle the lava rocks directly on top of the
burner just behind decorative grate. (Fig. 24) Do not
place lava rocks toward back of burner. The lava
rock is shipped inside the bag assembly.
