Alpine SE42 Direct Vent Gas Fireplace
POSITIVE PRESSURE SYSTEM
POSITIVE PRESSURE SYSTEM
The Alpine SE-36 is equipped with a highly efficient
positive pressure heating system. This system provides
outside air for heating. The appliance has been provided
with a blower, blower housing, and blower controller. The
items below are requirements for the system to work safely
and properly.
System Requirements
1. The Positive Pressure system must be ducted to an
outside air source or ventilated attic. Air should not be
taken directly from a ventilated or non-ventilated crawl
space, as freezing of adjacent water piping may occur.
2. The duct may be run an unlimited number of ways;
however, the straighter the duct, and the shorter the duct
run, the better the air flow will be.
3. In some installations, the blower and the blower housing
may be installed near the appliance. If installed near the
appliance, the blower housing must be sealed shut and
additional ducting run from the blower housing to an
outside air source or ventilated attic space.
4. The blower adapter, blower, and blower housing must be
securely anchored to minimize vibration noise.
5. The blower must remain accessible for future
maintenance.
6. It is critical that the air intake for the positive pressure
system and the vent outlet or termination be spaced a
minimum of 3’ apart. The intake should also NEVER BE
PLACED ABOVE the exhaust vent outlet on the exterior
of the home.
7. Any questions regarding the proper installation of the
Positive Pressure system should be directed to your Alpine
Dealer.
SYSTEM OPTIONS
Typical installation of the Positive Pressure system into a
new construction installation is drawn in (figures 20 and
21).
If the installation is to be below grade, the ducting must be
lengthened and installed as in (figure 22).
The blower housing comes as an unassembled kit. See the
kit container for housing assembly instructions.
