Insert Leveling - Lennox Hearth Products Shoreline 33/40 DV INS Installation And Operation Manual

Vertical Venting
The vent pipes must be connected to the proper collars on the unit and
the exhaust vent pipe must be connected to the termination cap or the
unit will not operate. The combustion air vent pipe can be connected to
the termination cap (see Figure 6b) or it can terminate inside the chimney
(see Figure 6a). The bottom opening of the chimney must be sealed
around the vent pipes if the combustion air vent is not connected to the
termination cap. Use unfaced fiberglass insulation to seal around the vent
pipes or a positive flue connection using a seal-off plate. The insulation
may give off an odor during the first hour of operation.
NOTES:
The minimum vertical rise (exhaust vent) is 10 feet (3.05 M) and the
maximum vertical rise is 35 feet (10.67 M). These dimensions are
measured from the flue collar of the unit to the end of the vent pipe,
The fireplace and fireplace chimney must be clean and in good working
order and constructed of non-combustible materials. Inspect chimney
clean-outs for proper fit and seal.
See Table 5 for the minimum vertical termination height requirements.

Insert Leveling

At each front and rear corner of the insert is an adjustable leg provided
to level the insert should the hearth of the fireplace be uneven. To adjust
the legs in the rear, loosen the two 5/32" allen head screws, move the leg
to the desired height, and then tighten the screws. Repeat these steps
for each adjusting leg. To adjust the legs in the front use a 9/16" open
end wrench. See Figures 7 and 8.
