HTP Elite FT Series User Manual

LP-387 Rev. 011 Rel. 005 Date 1.3.19
32
instructions reference snow levels in establishing a minimum height
for the installation of exhaust vent or air intake terminations. Snow
levels shall be determined as follows:
a. The installation location may, by ordinance, designate how snow
levels are calculated in that location; or
b. In the absence of specic ordinances, snow levels shall be
calculated from the average monthly maximum depth of snow
accumulation as indicated by the National Weather Service’s 10
year statistics for the installation location/geographical area.
In addition:
• Total length of vent piping shall not exceed the limits specied
in this manual.
• The vent piping for this direct vented appliance is approved
for zero clearance to combustible construction.
• The ue products coming from the exhaust vent will create a
large plume when the heater is in operation. Avoid venting in
areas that will aect 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 sot 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
nished grade, a metal or plastic identication 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.

H. Applications
1. Direct Vent Installation of Exhaust and Intake
If installing a direct vent option, combustion air must be drawn
from the outdoors directly into the boiler intake, and exhaust must
terminate outside. There are three basic direct vent options detailed in
this manual: 1. Side Wall Venting, 2. Roof Venting, and 3. Unbalanced
Venting.
Be sure to locate the boiler such that the exhaust vent and intake
pipe can be routed through the building and properly terminated.
Dierent vent terminals can be used to simplify and eliminate multiple
penetrations in the building structure (see Optional Equipment in
Venting Section). The exhaust vent and intake pipe lengths, routing
and termination methods must all comply with the methods and limits
given in the Venting section of this manual.
When installing a combustion air intake from outdoors, care must be
taken to utilize uncontaminated combustion air. NOTE: To prevent
combustion air contamination, see Table 2.
