GAS CONNECTIONS
1) Install the final gas nipple into the fireplace insert
(the nipple should only extend about 3” past the
interior wall of the fireplace insert).
2) Connect the appliance gas shut off valve and
proceed to check for leaks
(consult local building
officials for the accepted test procedure in your
area)
.
3) After testing the system for leaks, install the
connect the flexible appliance adapter to the gas
line.
4) Turn the gas supply on to the fireplace and test
again for gas leaks.
LOG INSTALLATION
Gently remove the logs from their packaging.
Place the two largest logs on the locating pins on the
burner (the bigger of the two placed in the front and
the smaller placed to the rear). The face of the back
log should be even with the back of the burner,
centered, and then gently pushed down onto the
locating pin. The face of the front log should be
behind the front of the burner approximately 1/2 of an
inch and centered.
The number of top logs will vary depending
on the size of the insert (see fig. 8A & 8B). The 360
and 310 models have three top logs while the 270
model has two top logs. The top logs should be placed
on the cut out pads located on the top surface of the
two largest logs. They must be located in these
positions to avoid combustion related problems.

UNIT TESTING AND ADJUSTMENTS
AERATION ADJUSTMENT
Pilot Light Adjustment
The pilot light is preset at the factory and should
require no adjustment. The flame on the pilot should
project about 5/8” past the pilot head, with enough
flame to impinge on both the thermocouple on the left
side and the thermopile on the right side of the pilot
head
.
If the pilot is erratic, noisy, or yellow, call your
Alpine Fireplaces Dealer or another qualified service
technician to make the adjustment.
(Refer to figure 9A)
NOTE: The appliance and its individual shut off
valve must be disconnected from the gas supply
piping system during any pressure testing of that
system in excess of 1/2 psig.
The appliance must be isolated from the gas
supply piping system by closing its individual
manual shut off valve during any pressure testing
of the gas supply piping system when test
pressures are equal to or less than 1/2 psig.

Note: A flame hitting directly on the bottom of a
log will burn dirty and cause excessive soot build
up on the log and inside the firebox.
