Installing and Securing Unit to Wall Sleeve
Before installing and securing the unit to the wall sleeve,
make sure that the proper louver is installed. Due to the
high temperatures of the combustion products released
from the vent pipe, these units require the use of either
an aluminum louver or polypropylene louver (see the
Accessories section).
1. Make sure the gaskets attached to the sleeve are not
damaged.
2. Verify divider panel is positioned properly. Refer to
Table 2 for wall sleeves that allow for multiple divider
panel locations.
3. Place the unit into the wall sleeve. Lift leading end of
unit and walk unit onto the sleeve. Once in the wall
sleeve, lower the unit into position. This prevents
damage to the base pads. Assure that the unit is level
and completely seated against the gaskets on the
wall sleeve. The unit must be supported by a field-
fabricated and supplied platform.

4. Use the two installation brackets to secure the unit to
the wall sleeve (see Figure 7). The units are shipped
with the brackets placed loose on the unit top panel,
beneath packaging. Hook each bracket into the front
edge of the wall sleeve side panel. Position the bracket
so it can be bent around the front corner of the unit.
Remove one of the two screws in that position on the
unit. Line up one of the holes in the installation bracket
with the screw hole and attach the bracket to the unit
with that screw. Make sure to fasten tight enough
that the seal is maintained. Trim off excess bracket if
applicable.
5. Inspect the fit up of the unit to the wall sleeve. Verify
that the gaskets of the wall sleeve make a complete
seal to the unit paying particular attention to top and
bottom corners of unit to sleeve seal. Caulk if needed.
Venting
The venting system is an integral part of the appliance.
The venting system must not be modified in any manner
other than what is specified in these instructions.
This appliance should be installed in a location such that
the vent outlet is located in the following manner:
1. Distances to windows that open, building openings, or
public walkways should be consistent with the National
Fuel Gas Code Z223.1.
2. For U.S. installations, the vent system shall terminate
a minimum horizontal clearance of 4’ from electric
meters, regulators, and relief equipment.
3. Flue products from properly adjusted and maintained
units, should not cause degradation to building
materials.
The unit contains a combustion air inducer. The inducer
draws the combustion products out of the heat exchanger
together with dilution air and forces the mixture from the
unit to the outside. No special provisions are required for
supplying air for combustion, nor is a chimney required as
this is a direct vent appliance.
The vent outlet must be extended (see Vent Pipe
Installation).
The venting system is designed for proper operation under
most weather conditions and for wind speeds up to 40 miles
per hour. The venting system should be unobstructed for a
minimum of 2 feet.
Existing Venting Systems
When an existing furnace is removed and replaced, the
MGE4 unit venting system may no longer be sized to
properly vent the attached appliances. An improperly sized
venting system can result in spillage of flue products into
the living space, the formation of condensate, leakage, etc.
Refer to the CAUTION box in the next column for proper
test procedure.
