Venting Requirements - Empire Comfort Systems Mantis Instructions D'installation

WARNING
This appliance must not be vented with any other
appliances, even if that appliance is of the condensing type.
Common venting can result in severe corrosion of other
appliances or their venting and can allow combustion gas-
es to escape through such appliances or vents. Do not
vent the heater into a fireplace chimney or building chase.
WARNING
Upon completion of the installation, carefully inspect the
entire flue system to assure it is properly sealed. DO NOT
use any vent material other than what is specified in this
manual. Leaks in the flue system can result in serious
personal injury or death due to exposure of flue products,
including carbon monoxide.
The Mantis is classified as a "Category IV" appliance, which
requires special venting materials and installation procedures.
Installations can be Conventional (one-pipe) and Direct Vent
(two-pipe). In selecting a location for installation, it is neces-
sary to provide adequate clearances for servicing and proper
installation.
All vent and combustion air pipes and fittings must be Sched-
ule 40 PVC and meet the ANSI/ASTM Standard D1785. Ce-
ment must conform to ASTM Standard D2564.
Installation in Canada must conform to the requirements of
CSA B149 code. Vent systems must be composed of pipe, fit-
tings, cements, and primers listed to ULC S636. In Canada,
the primer and cement must be of the same manufacturer as
the vent system; do not mix primers and cements from one
manufacturer with a vent system from a different manufacturer.
Follow the manufacturer's instructions the use of primer and
cement and never use primer or cement beyond its expiration
date.
The safe operation, as defined by ULC S636, of the vent system
is based on following these installation instructions, the vent
system manufacturer's installation instructions, and proper use
of primer and cement. Acceptability under Canadian standard
CSA B149 is dependent upon full compliance with all installa-
tion instructions. Under this standard, it is recommended that
the vent system be checked once a year by qualified service
personnel. The authority having jurisdiction (gas inspection
authority, municipal building department, fire department, etc)
should be consulted before installation to determine the need
to obtain a permit.
The maximum vent length is 40 feet equivalent with three
90° elbows. The minimum vent length is twelve inches.
Each 90° elbow used in the vent system will be the equivalent
to three feet, and each 45° elbow is equivalent to 1.5 feet, which
should be added to the overall vent length.

Systems, ULC S636.
B. A maintenance schedule, when a means is provided
to neutralize condensate, if required.
C. Periodic cleaning of the condensate collection and
disposal system(s), if required.
D. For Category IV appliances:
(1) When the manufacturer supplies the venting sys-
tem, the instructions shall include a parts list and
instructions covering the installation of properly
identified parts to provide for the venting of the
vent gases to the outdoors.
(2) When the parts for venting the vent gases are not

cific types listed by a nationally recognized test-
ing agency, these instructions shall clearly identify
and specify the use of the specific parts.
2. For Category IV appliances, the venting system shall be
installed in accordance with the appliance manufacturer's
instructions.

(1) Be supported to prevent sagging. The methods of
and intervals for supports shall be specified in the
installation manuals.
(2) Slope upwards not less than 1/4 in/ft (21 mm/m)
from the appliance to the vent terminal.
(3) Category IV appliances shall be installed so as to
prevent accumulation of condensate in the vent-
ing system.
4. Category IV appliance installations shall provide a means
for removal of condensate.
5. For appliance installation instructions accompanying a di-
rect vent appliance or other appliance that can utilize a
side wall vent system shall include information on where
the vent terminal can and cannot terminate, including:
For Category IV appliances, the following statement:
The vent for this appliance shall not terminate:
(a) Over public walkways; or
(b) Near soffit vents or crawl space vents or other
