Locating The Boiler
1.
Place crated boiler as close to selected location as
possible and un-crate boiler. Boiler may be moved into
position with appliance dolly or 2 wheel hand truck.
Insert dolly or hand truck under left hand side of
boiler. It is possible to slide boiler for short distance on
smooth floor or surface.
2.
Select level location central to piping systems served
and as close to vent and air intake terminals as
possible.
3.
Accessibility clearances, if more stringent (i.e. larger
clearances) than required fire protection clearances,
must be used for boiler installation. Accessibility
clearances may be achieved with the use of removable
walls or partitions.
4.
Boiler is approved for installation in closets and on
combustible floors. This boiler shall NOT be installed on
carpeting.
5.
Clearances shown in Table 4 indicate required
clearances. Maintain minimum 1" clearance between
combustible construction and each of left, top and
back surfaces of the boiler. Minimum 11" clearance is
required on right side, to allow room for induced draft
blower. Allow 24" at front and 8" at top for servicing.
No clearances are required to venting or combustion air
intake piping.
6.
Install equipment in location which facilitates operation
of venting and combustion air intake piping systems
as described in this manual. Draft inducer (blower)
may be rotated 90° or 180° to orient vent connections
towards right side or rear. Remove blower mounting
screws. Orient blower and install mounting screws. Do
not overtighten screws.
7.
Advise owner to keep venting and combustion air
intake passages free of obstructions. Both venting
and combustion air intake piping systems connected
to outdoors must permit flow through piping systems
without restrictions for boiler operation.
8.
Install boiler such that the automatic gas ignition
system components are protected from water
(dripping, spraying, rain, etc.) during operation and
service (circulator replacement, condensate trap,
control replacement, etc.).
9.
Keep boiler area clean of debris and free of flammable
and combustible materials, vapors and liquids.
10.
Locate boiler where minimum possible room
temperature where boiler is installed, assuming boiler
is not in operation and therefore contributes no heat
to space, is always at or above 32°F (0°C) to prevent
freezing of liquid condensate.
BOILER INSTALLATION
Combustion Air And Vent Pipe Requirements
This boiler requires a dedicated direct vent system. In a
direct vent system, all air for combustion is taken directly
from outside atmosphere, and all flue products are
discharged to outside atmosphere.
Terminate combustion air and vent pipe connections in
same atmospheric pressure zone, through roof or sidewall
(roof termination preferred). See Figure 12 thru Figure 14,
pages 24 and 25 for required clearances.
Solvent cements are combustible. Keep away
from heat, sparks, and open flame. Use only in
well ventilated areas. Avoid breathing in vapor or
allowing contact with skin or eyes. Failure to follow
these instructions could result in fire, serious injury,
or death.
• Combustion air must be clean outdoor air. Combustion
air must not be taken from inside structure because
that air frequently is contaminated by halogens, which
include fluorides, chlorides, phosphates, bromides
and iodides. These elements are found in aerosols,
detergents, bleaches, cleaning solvents, salts, air
fresheners, paints, adhesives and other household
products.
• Locate combustion air inlet as far away as possible
from swimming pool and swimming pool pump house.
• All combustion air and vent pipes must be airtight and
watertight. Combustion air and vent piping must also
terminate as shown in "Combustion Air and Vent
Pipe" section.
• Vent connections serving appliances vented by
natural draft shall not be connected into any portion
of mechanical draft systems operating under positive
pressure.
