Alpine TR42 Direct Vent Gas Fireplace
WIRING/LOG INSTALLATION
When installing the low voltage wiring it is essential that
the wires be marked so as to never have 110 volt /24 volt
power attached to them. If power is attached to the control
valve, damage will certainly occur.
The appliance generates the millivoltage needed to operate
the gas control system. A standard wall toggle switch or a
millivolt thermostat may be used to control the main gas
valve.
The millivolt system has limitations on the distance it can
be installed from the fireplace. The greater the distance
from the fireplace, the larger the wire size must be to
prevent loss of the millivoltage. See the table below for
recommendations.

Millivolt thermostats and remote controlled millivolt
thermostats are available from your Alpine dealer.
See (figure 20) for wiring illustration of the control valve.
A snug connection must be made at the control valve and
the switch location to ensure reliable operation. Do not
over tighten the screws at the control valve, they will strip.
Note: Local codes need to be followed when installing
any electrical appliance. If conflicts between this
manual and local electrical codes exist. Local codes
always prevail.

LOG INSTALLATION
Fig. 22 – Side Logs
Locate the back log (42-1) and position it over the locating
pins on the back of the burner. ( fig. 21)
Locate the left side log (42-2) and place it so the flat side
faces the left side wall. Push it back against the back log
and swing the front towards the center of the firebox until
the log hits the grate. Locate the right side log (42-3) and
position it so the flat side faces the right side wall. Push it
back against the back log and swing the front towards the
center of the firebox until the log hits the grate. ( fig.22)
Fig. 21 – Back Log
Carefully remove logs from their packaging . You will
notice that your Alpine Gas Fireplace logs are extremely
lightweight and are very fragile, care must be taken when
handling. It is also important to note that the positioning of
the logs in the fireplace is very critical , the logs must be
installed as instructed in this manual to maintain an attrac-
tive and clean burn.
NOTE: DO NOT CHANGE THE
LOGS ORDER OF INSTALLATION IN ANY WAY.
