In the State of Massachusetts:
This product must be installed by a licensed plumber •
or gas fi tter.

•
length shall not exceed 36 inches.
When lever type gas shut-offs are used, they shall
•
be T-handle type.
Installers - Follow local regulations with respect to
installation of CO (Carbon Monoxide) Detectors. Follow
maintenance recommendations in this manual.
Boiler Sizing
Check to be sure you have selected the boiler with •
the proper capacity before continuing the installation.
The I=B=R Rating of the boiler selected should be
greater than or equal to the calculated peak heating
load (heat loss) for the building or area(s) served by
the boiler and associated hot water heating systems.
See “Boiler Ratings and Capacities,” (page 4) for more
information.
Heat loss calculations should be based on approved
•
industry methods.
Considerations For Boiler Location
Before selecting a location for the boiler, the following
should be considered. Each boiler considered for
installation must be:
Supplied with the correct type of gas (natural gas or •
propane).
Connected to a suitable combustion air intake piping
•
system to supply the correct amounts of fresh
(outdoor) air for combustion (max. length 60’).
Connected to a suitable venting system to remove
•
the hazardous products of gas combustion (max.
length 60’).
Connected to a suitable hot water heating system.
•
Supplied with a suitable electrical supply for all •
boiler motors and controls.
Connected to a properly located thermostat or
•
operating control. (Not included with boiler)
Placed on level surface (must NOT be installed on
•
carpeting)
Condensate drain line must be pitched down to fl oor
•
drain or external condensate pump with reservoir at
¼” per foot (21 mm/m) (wood frame or blocks may
be used to raise boiler).
Locating The Boiler
Select location which is level, central to piping systems
1.
served and as close to vent and air intake terminals as
possible.
Accessibility clearances, if more stringent (i.e. larger
2.
clearances) than required fi re protection clearances,
must be used for boiler installation. Accessibility
clearances may be achieved with use of removable
walls or partitions.
Boiler is approved for installation in closets and on
3.
combustible fl oors. Boiler shall NOT be installed on
carpeting.
Clearances shown in Table 4 indicate required
4.
clearances per CSA listing. Minimum 1” (25 mm)
clearance must be maintained between combustible
construction and each of the right, top and back
surfaces of boiler. Minimum 8” (203 mm) clearance is
required on left side, to allow room for inlet air pipe.
18” (457 mm) clearance must be maintained at front
where passage is required for cleaning or servicing,
inspection or replacement of any parts that normally
may require such attention. Allow at least 24” (610
mm) at front and left side and 8” (203 mm) at top for
servicing. No combustible clearances are required to
venting or combustion air intake piping.
