Vented Application Installation; Nb, Nbsc Models - Monessen Hearth NB18 Installation And Operating Instructions Manual

NB18/NB24 Gas Log Set
VENTED APPLICATIONS ONLY
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),
reposition 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.
ASSEMBLY PROCEDURE
1. Center the gas log unit on the fireplace or firebox. Make certain the front of the burner sits
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 burner
correctly, mark the hole positions on the fireplace/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 13
Proper installation of the grate is essential to prevent any movement of the gas logs
and controls during operation.

Securing Heater to Floor of Fireplace/Firebox
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 gas 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 on Page 6.
