Combustion Air - Pacific energy pacific vista Operating Instructions Manual

Combustion Air

Intake or combustion air can be supplied to the stove
in one of two ways. Consult your local building code or
Installation Code for Solid-Fuel-Burning Appliances and
Equipment before proceeding.
1. Outside air supply - (Necessary for mobile home
installation, optional for residential installation.) Outside
air may be drawn from either underneath the stove or
from behind.
To draw outside air through the fl oor, leave the 100mm
knockout or cover plate in place in the rear of the
pedestal or leg kit ash box enclosure.
Pedestal Model: Cut or drill a 100mm diameter
hole in the fl oor anywhere inside the perimeter of the
pedestal. Cover the hole with a (100 mm x 100 mm)
rodent screen and staple/nail in place.
Leg Model: Cut or drill a 100mm diameter hole di-
rectly below the bottom hole of the ash box enclosure.
Connect enclosure to the fl oor with a short 100mm
diameter pipe. If you wish to connect the outside air to
the rear hole on the ash box, then remove the 100mm
knockout or cover plate at the rear of the ash box.
This hole must get its air from a ventilated crawl
space or be extended with duct to the outdoors (see
Figure #4). The use of outside combustion air for
residential installation requires the unit to be secured
to the structure to prevent dislodging of the air duct.

To draw outside air from behind the stove, an outside
air adaptor may be required cut or drill a 100mm hole
through a wall behind the unit. Use an appropriate
household 100mm inlet. You must remove the rear
cover plate from the pedestal or move the cover plate
at the rear of the leg kit ash box enclosure to cover
the bottom hole.
Note: This unit is not designed to be operated with the
fi ring door open. In addition to the obvious hazard of
sparks landing on combustibles, an open fi re door will
cause the heater to draw air from the living space and
possibly cause suffocation.
2. Room air supply - Remove the cover plate from the
rear of the pedestal or leg kit ash box enclosure. The
stove will now draw its air from the room through this
opening and into the fi rebox intake.
Note: 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. During extremely cold
weather, and especially when burning at very slow
rates, the upper parts of the exposed chimney may
ice up, partially blocking the fl ue gases. If blockage
occurs, fl ue gases may enter living space.
