INSTALLATION
MOUNTING TRIM PANELS FOR MASONRY INSTALLATION
(Changes refer to pages 9 and 10 in your owners manual)
POSITIONING THE HEATER
When positioning the heater, the following conditions
MUST be met! (See Figure 2)
1. The front of the damper opening must be positioned
BEHIND the rear edge of the lintel to ensure proper
draft. (See Figure 2)
2. The vertical plane of the fireplace front must fall
BEHIND the side cold air vent on top of the unit. (In
other words, it is possible to have the heater too far in
as well as not far enough.)
3. Center the heater in the fireplace opening.
MOUNTING THE TRIM PANELS
After the unit is positioned, as shown in Figure 2, mark the
mounting position of the trim panels as follows:
1. Set the top (long) trim panel in place on top of the unit.
The panel should be flat against the outside face of the
fireplace, and standing vertically. Mark along the
lower edge of the trim panel with a pencil to make a
reference line for mounting.
2. Set the side trim panels in place behind and against the
intake covers, again, flat against the face of the
fireplace. Mark down the edge of the trim panel to
make a vertical reference line.
