Operation and Maintenance Manual
Chap 3:
Installation
3.2.2 Boiler Location
The boiler should be located on a level, solid area or base as near to the outside wall as possible and
centrally located to the space heating distribution system. Special attention must be given to local
regulations and codes about boiler rooms and particularly to the maintaining of minimum clearances and
empty space around the boiler. The installation must be in compliance with all recent regulations and
laws about boiler rooms, installations of heating and hot water systems, ventilation, boiler venting
systems capable of evacuating the flue gases of condensing boilers and any other applicable
requirement.
The minimum clearance dimensions for service access, required by AERCO, are listed below (
Figure
3-2
) and on the boiler Data Plate (
Figure 3-8
). Local building codes may require more clearance and
take precedence.
Minimum clearances required:
Sides
24" (510 mm)
Front
24" (510 mm)
Rear
24" (510 mm)
Top
24" (510 mm
)

NOTE
All gas piping, water piping and electrical conduit or cable must be
arranged so that they do not interfere with the removal of any cover, or
inhibit service or maintenance of the unit.
The boiler
MUST NOT
be installed on carpeting.
3.2.3 Pad Height for Boiler
To properly drain and service the boiler’s condensate system, attention must be given to installation
requirements regarding the mounting height of the boiler as well as installation clearances for the
removal of the condensate collector baffle.
The boiler should be mounted on a flat and sufficiently strong base with the same dimensions as the
boiler (see
Table 2-2
) and at least 4 inches (100mm) high, to allow for assembly of the condensate
drain trap (
Figure 5-1
). An alternative to this base may be a 4 inch (100mm) deep well next to the
boiler to house the condensate siphon.
The condensate collector baffle (
Figure 8-12
) can be fixed to the right-hand or left-hand side of the
condensate tray. If no modification is made, the boiler must have its right-hand side accessible,
whether the vent connection is fitted on the right-hand or left-hand side. However, if the flue collector
terminal, with the exhaust connector, is left of the right-hand side, and if, from this same side, the baffle
has to be removed, then the exhaust connector must have the possibility to also be removed. If it is
preferred, the baffle can be moved in order to have its mounting screw on the opposite side, regardless
of the position of the flue collector chamber terminal.
