SECTION 3.
Installation
3A. Freight Claims
The boiler and it's components should be
inspected for damage upon arrival and any claim filed
immediately against the carrier by the consignee. The
carrier is responsible for taking prompt action on all
claims.
3B. Regulations
THE BOILER INSTALLATION MUST BE
CARRIED OUT BY A QUALIFIED INSTALLER
IN ACCORDANCE WITH THE REGULATIONS
OF AUTHORITIES HAVING JURISDICTION
AND CSA STANDARD B139 or ANSI / NFPA 31
Installation of Oil Burning Equipment - latest edition,
the National Electrical Code ANSI / NFPA 70 - latest
edition and local codes and authorities having
jurisdiction. Such applicable requirements take
precedence over the general requirements contained
herein.
The installer must also be properly licensed and
experienced in all the codes and ordinances.
WARNING
In the interest of safety, gasoline or other flammable
fluids or vapors must not be stored or used in the
vicinity of the boiler.
3C. Sizing the System
Over sizing the boiler will cause short cycling
and reduce its operational efficiency, so it is
recommended that a building heat loss calculation is
made to ensure that the correct size boiler is used
(
see Table 1 ).
3D. Location
The boiler should be mounted on a solid level
floor and located as close as possible to the chimney
or the position chosen for the direct vent terminal.
The boiler can be mounted on a combustible floor due
to its wet base construction, however, a check should
be made to ensure the floor is capable of supporting
the installed weight of the boiler including its water
content.
A closet may be used to enclose the boiler,
providing the enclosure is properly vented to ensure
the controls do not become overheated (see
Ventilation Air section). The boiler must also have the
correct amount of air available for combustion when
using a conventional chimney (see Combustion Air
section).
When installed, the boiler must be level. If
necessary use metal shims under the base to level the
unit particularly front to back otherwise air could be
trapped inside the boiler.
3E. Clearance
Adequate clearance should be allowed around
the boiler for cleaning and servicing. The following
minimum clearances are recommended:
Front - 24" (610mm) (for hinging door)
Rear - 6" (152mm)
Sides - 6" (152mm)
Clearance from combustible materials should be in
accordance with local and national codes. Guidance is
given in the National Fire Protection Bulletin NFPA,
Installation of Oil Burning Equipment. All other
applicable codes should also be followed.
3F. Combustion Air
(other than direct vent)
WARNING
As an additional measure of safety, Laars strongly
recommends installation of suitable Carbon
Monoxide detectors in the vicinity of this appliance
and in any adjacent occupied spaces.
AVERTISSEMENT
Laars recommande fortement, comme mesure de
sécurité supplémentaire, l'installation de détecteurs
de monoxyde de carbone adaptés dans le voisinage
de l'appareil et dans chacune des pièces habitées
adjacentes.
Chimney Vent: For boilers installed in
basements, infiltration may be adequate to provide
combustion air. For buildings of exceptionally tight
construction, the boiler must be installed in an
unconfined space, or in an area which directly
communicates with an unconfined space. An
unconfined space is a space whose volume is 50 cubic
ft. (1.4m3) or more per 1,000 BTU (293kW) of the
aggregate input of all appliances in that space. Two
openings to the space, one 6" (152mm) from the floor
and one 6" (152mm) from the ceiling of the enclosure
must be provided. Each opening must have at least
168 square inches (1084 sq.cm) of free area.
Chimney Vent with outside air duct connected
directly to burner: In an installation of exceptionally
tight construction, intake air may be ducted directly to
the burner from the outdoors. On an AF2 burner
remove the black air intake shroud to connect the 4"
(102mm) aluminium duct (up to 15 equivalent ft.
[4.6m] maximum). Terminate the duct on the outside
of the building with a suitable protective cover. This
cover must be located at least 16" (406mm) above
grade or above an anticipated snow line.
