Vermont Castings NBST27 Installation Instructions Manual page 11

VENTED APPLICATION INSTALLATION / SECURE APPLIANCE
The fireplace and gas logs function as a system. If the fireplace is
spilling into the room (check with a match or a smoke stick), reposi-
tion the damper clamp until a positive draft is obtained by opening the
damper. If negative pressure in home prevents having a positive draft,
contact your dealer for assistance.
You must secure the gas log heater to the fireplace floor. If not, the
entire unit may move when you adjust the controls. Movement of unit
may cause shifting of the logs which leads to sooting and improper
burning. Grate movement could cause a gas leak.
Special care is required if you are installing the unit into a sunken
fireplace. You must raise the fireplace floor to allow access to gas log
controls. This will insure adequate air flow and guard against sooting.
Raise the fireplace floor using noncombustible materials, as described
in "Placement in a Fireplace with Restrictive Barrier" section.
PLACE and SECURE APPLIANCE
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. Anchor holes are located on the right and left sides of the unit. After centering the grate
correctly, mark the hole locations on the fireplace/firebox floor. Drill two (2) 5/32" diam-
eter holes approximately 1Z\x" deep.
3. Anchor the unit to the fireplace/firebox floor using the
screws provided. Figure 11
Proper installation of the grate is essential to
prevent any movement of the logs and con-
trols during operation.
RIGHT CORNER APPLICATIONS
For right corner installations, the piezo ignitor
can be moved to the opposite corner of the ap-
pliance:
1. Remove wire from back of ignitor.
2. Remove two (2) screws holding piezo brack-
et.
3. Reattach bracket on the opposite corner
(where inlet fuel comes into the valve) by us-
ing two clearance holes on burner base.
4. Reattach wire to ignitor.
