•
The flue products coming from the exhaust vent will create a
large plume when the heater is in operation. Avoid venting in
areas that will affect neighboring buildings or be considered
objectionable.
•
DO NOT locate exhaust vent or intake pipe in a parking area
where machinery may damage the pipe.
•
DO NOT vent near soffit vents, crawl space vents, or other areas
where condensate or vapor could create a nuisance or hazard
or cause property damage.
•
DO NOT vent where condensate vapor could cause damage
or could be detrimental to the operation of regulators, relief
valve, or other equipment.
In the Commonwealth of Massachusetts and as Required by
State and Local Codes:
•
The vented gas fueled appliance shall not be installed so its
combustion, ventilation, or dilution air is obtained from a
bedroom or bathroom.
•
Signage: Whenever any through-the-wall (horizontal or
sidewall) vent is installed less than seven feet above the
finished grade, a metal or plastic identification plate shall
be permanently mounted to the exterior of the building at
a minimum height of eight feet above grade directly in line
with the exhaust vent terminal. The sign shall read, in print no
less than 0.5 inches in size, “GAS VENT DIRECTLY BELOW. KEEP
CLEAR OF ALL OBSTRUCTIONS”.
•
Marking of Exhaust Vent and Intake Pipe: Piping used for
ventilation, make-up, or combustion air intake shall be labeled
as follows:
a. Throughout the entire developed length:
i. Labels must be placed every ten feet for exposed/visible
piping; or
ii. Labels must be placed every three feet for concealed
piping.
b. At all changes of direction;
c. On each side of a penetration through a partition, wall or
ceiling; and
d. The labels shall be black lettering that:
i. Indicates that the piping is used for ventilation, make-up, or
combustion air intake, and
ii. The letters shall be sized equal to a minimum of the pipe
diameter. However, for piping with a diameter exceeding two
inches, said lettering does not need to be larger than two
inches.

1 Instructions included with termination kits contain detailed assembly and installation instructions.
2 Clearance requirements in this manual supersede those of the instructions included with the vent terminal.
3 Piping MUST be secured to the vent terminal during installation.
4 IPEX Concentric Terminal MUST be cemented together and to the vent pipes during installation.
5 Vent Screens provided with boiler may be used with the IPEX Concentric Vent Kits; otherwise use IPEX vent screens (2 in. vent screen p/n 196050; 3 in. vent
screen p/n 196051 - each sold separately).
6 IPEX Low Profile and Concentric kits (exluding p/n 197117) are constructed out of ULC-S636 approved PVC. Check with your local authority for the
