Installing Vented Applications - Monessen Hearth HVFL24 Installation And Operating Instructions Manual

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.
PLACING AND SECURING APPLIANCE
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 11.
ASSEMBLY PROCEDURE:
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 in front of the unit and in the back (right and left sides) of the unit. After centering the grate
correctly, mark the hole positions on the fireplace/firebox floor. Drill two (2)
1 1 / " deep.

3. Anchor the grate to the fireplace/firebox floor using the screws provided. See Figure 14.
