4. Installation
1. Use the following guidelines to position the air/vent
termination.
2. The surroundings must be taken into consideration
when termination the air and vent:
a. The vent termination must be positioned in such
a way as to avoid damaging nearby bushes,
air conditioning equipment, plants and be
aesthetically pleasing.
b. When the air is cold, there will be a noticeable
plume produced from the flue gas product.
Avoid any areas where the plume could be an
obstruction to a window view.
c. Where the flue products impinge on plants or
the building surface, prevailing winds could
cause freezing of the condensate and possible
water/ ice build-up.
d. Avoid any possibility of people and pets
accidentally coming in contact with the flue
products.
e. Never locate the air or vent terminations in
areas such as stairwells, window wells, inside
building corners, courtyards, near adjacent
buildings or surfaces, alcoves, or other recessed
areas.
f. Never terminate under a deck or above any door
or window. Ice formations can be caused by the
condensate freezing.
g. The vent should be positioned or guarded in
such a way that it prevents condensate damage
to the exterior finishes.
3. Ensure the clearances on page 44 are maintained
and the following must also be adhered to:
a. The vent must terminate:
- A minimum of 6’/2 m from any adjacent wall.
- A minimum of 7’/2.1 m above any public
doorway.
- No closer than 5’/1.5 m below a roof
overhang.
- A minimum of 3’/1 m above any forced air
intake within a 10’/3 m distance.
- No closer than 12”/305 mm below or
horizontally from any window, door, or any other
gravity air inlet.
b. The air inlet must have at least a 12”/305 mm
clearance above the grade or snow line.
c. A minimum distance of 4’/1.2 m horizontally,
above or below, must be kept from any electric
meter, regulator, relief valve, gas meter, or any
other equipment.
4. Ensure that the terminations are located in areas
where they are not going to be damaged by foreign
objects such as stones, balls, or subjected to the
build-up of sediment or leaves.
Multiple air/vent terminations
1. For the termination of more than one MCA Pro boiler,
ensure that the instructions in this manual are followed
for each air/vent termination connection.
DANGER
All of the air inlets and vent pipes must be terminated
at identical heights to avoid the possibility of death,
severe personal injury or substantial product/property
damage.
1. Follow the instructions and example on page
44 in order to obtain the minimum clearance
required for US installations. For the Canadian
installations follow the required clearances as per
the CSA B149.1 or B149.2 Installation Code.
2. The MCA Pro air inlet is part of a direct vent
connection and as such is not classified as a
forced air intake with regards to the spacing from
any adjacent boiler vents.
