VENTING INSTALLATION
Follow the vent material manufacturer’s instructions in
conjunction with these instructions for venting system
installation.
I. Non-Direct Vent Installation
The air for combustion is taken from the ambient air
surrounding the boiler; therefore, ample supply of air is
required for combustion and ventilation (see page 5.)
DO NOT use this installation method if the surrounding of
the boiler is contaminated. The harmful corrosive
contamination may be from the chlorine-type detergents,
cleaners, bleaches, and fabric softeners used in laundry or
chlorine-based swimming pool chemicals.
A. SIDEWALL VENTING - NON-DIRECT VENT
Figures 5 and 6 show typical horizontal sidewall venting. For
combustible wall passage of vent piping, a UL or CSA listed
thimble must be used, providing the wall thickness from 76
mm (3") minimum up to 305 mm (12") maximum. The vent
piping must terminate with a screened tee or elbow
termination facing down.
CAUTION: Flue gasses existing from the vent terminal will
condense. Building materials in the area of the vent terminal
should be protected from discoloration and degradation.
VENT TERMINATION LOCATION AND CLEARANCES
1. The venting system shall terminate at least 914 mm (36")
above any forced air inlet located within 3048 mm (120").
2. The venting system shall terminate at least 1219 mm
(48") below, 1219 mm (48") horizontally from, or 305 mm
(12") above any door, window or gravity air inlet into any
building. The bottom of the vent terminal or air intake ter-
minal shall be at least 305 mm (12") above grade or the
normal snow level whichever is greater.
3. Through the wall vents shall not terminate over public
walkways or over areas where condensate or vapor
could create a nuisance or hazard or could be detrimen-
tal to the operation of regulators, relief valves or other
equipment. Minimum clearance of 1219 mm (48") hori-
zontal distance is maintained, from electric meters, gas
meters, regulators and relief equipment.
4. Vent termination must not be located in any confined
space (i.e. window wells, alcoves, narrow alleys) or under
any overhang or deck. Vent termination should not allow
flue gas discharge towards neighbor’s windows or where
personal injury or property damages can occur.
B. NON-DIRECT VENT - VERTICAL VENTING
Figure 7 shows typical venting through the roof. The vent
pipe must pass through the ceiling, floor and the roof verti-
cally through a 178 mm (7") minimum diameter cutout. A fire
stop is required for each ceiling and floor penetration. For
roof passage, an appropriate UL listed roof flashing must be
used.
An existing chimney (see Figure 8) may be used as a chase
for vertical venting. Other appliances CANNOT be vented
into the same chimney or vent pipe with in the chimney.
The vertical vent piping must terminate with a screened tee,
or combination of 45° elbow and a 90° screened elbow
termination or a rain cap termination.
II. Direct Vent Installation
Air intake piping from outside to the boiler air intake collar
provides the air for combustion. The boiler surrounding may
be contaminated with chlorine-based products such as laun-
dry detergents.
A. SIDEWALL DIRECT VENTING
Figures 9 and 10 show typical sidewall direct venting.
Slant/Fin vent/air intake termination MUST be used for this
method of installation.
CAUTION: Flue gasses existing from the vent terminal will
condense. Building materials in the area of the terminal
should be protected from discoloration and degradation.
See page 4 for vent termination location and required
clearances.
VENT/AIR INTAKE TERMINATION INSTALLATION
1. Termination must be installed horizontally.
2 Refer to Figure 11 for installation details.
3. Wall thickness should be 76 to305 mm (3" to12") thick
4. Follow instruction for "vent termination location and
clearances" explained on this page.
5. Cut a rectangular opening with following dimensions in the
wall.
Height: 133 mm (51/4")
Width: 324 mm (1213/44")
6. From outside of the wall, install outside termination plate
using 4 screws. Make sure the louvers are at left side.
7. For combustible wall a 4" galvanized pipe must be used as
a wall thimble.
The length of the 4" galvanized pipe should be
approximately 25 mm (1") shorterthan the wall thickness.
8. From inside the building, fit galvanized pipe over4" collar
of the outside plate.
9. From inside, fit 3” diameterair intake pipe over3" collar
located on the air box of the outside plate.
