Into A Factory Built Fireplace; Combustion Air - Pacific energy Alderlea T5 LE Insert Installation And Operating Instructions Manual

Into a Factory Built Fireplace

Your Insert may be installed into a factory built fireplace (size permitting) with the following requirements:
1. Inspect your fireplace for damage or other physical defects. The fireplace must be in good working
condition. If in doubt about its condition, seek professional advice. Check for creosote build up or other
obstructions inside the chimney, especially if it has not been in use for some time. Before installing, clean
your chimney system thoroughly.
2. A full stainless steel rigid or flexible flue liner meeting type HT requirements (2100°F) per UL1777 (U.S.) or
ULC S635 (Canada) must be used for both safety and performance. The liner must be securely attached
to the Insert flue collar and the chimney top.
3. The surround must be sealed to the fireplace front or the damper area around the chimney liner must be
sealed to prevent room air entering the chimney cavity of the fireplace.
4. The air flow within and around the fireplace must not be altered by the installation of the Insert (i.e. no
blockage of louvers or cooling air inlet or outlet ports). This includes the circulating air chambers in a steel
fireplace or metal heat circulator.
5. Alteration of the fireplace in any manner is not permitted with the following exceptions:
• External trim pieces which do not affect the operation of the fireplace may be removed and stored on or
within the fireplace for re-assembly if the Insert is removed.
• The chimney damper may be removed to install the liner.

Combustion Air

Consult local building codes regarding combustion air supply. Intake or combustion air can be supplied to the
Insert in one of two ways:
1. Outside air (O/A) supply: Remove cover from ash clean out in existing fireplace. Place a rodent screen
in place of the cover. Install the Insert as described in the installation section, making sure not to cover
the opening of the air inlet. When installation is complete, seal surround to fireplace and anywhere else
air may enter. This will ensure combustion air is drawn from outside the house and into the intake on the
bottom of the appliance.
2. Room air supply: Remove the two screws securing the Decorative Cover under the ashlip. Remove
the screws holding the Room Air Cover to the Base bottom and discard the this cover. Re-install the
Decorative Cover and tighten screws (Figure 9). Combustion Air will be drawn from the room through the
front of the unit.
This unit is not designed to be operated with the firing
door open. In addition to the obvious hazard of sparks
landing on combustibles, an open fire door will cause the
heater to draw air from the living space and possibly cause
suffocation.
The living space around the heater must be well ventilated
with good air circulation. Anything that may cause a
negative pressure can cause gases or fumes to be pulled
into the living area.
